I use java FX to develop betting racing game,
Design .fxml files with
I want to make a game page, 20% of the screen contains a rounded horizontal bar below the sides of the screen. Contains the following elements from left to right:
1 circle contains the character image. connected to the game has a small rounded bar enough to display the character's name.
1 area containing the amount of money the character has, containing gold coins icon,
2 places to store 2 extra game icons for players to earn money. 1 is a predatory snake, the other one I haven't come up with yet.
About 80% of the screen left above I will think about it later

Suppose I am conducting a research paper on time series data entitled “The Nexus Among Oil Price, Stock Market, and Exchange Rate During Recent Pandemic & Russia-Ukraine Crisis: Fresh Evidence from UK Economy”. Here I have taken three variables Stock Index (SI), Brent Oil Price (OP), and Exchange Rate (ER). I have taken time series data from 2014-2023 segmenting into four periods. 2014-2019 for Pre-covid Period; 2020-2021 for Covid Period; 2022-2023 for War Period and 2014-2023 for the Overall Period. My Research Questions are:
1. Does each variable have a direct influence on others?
2. Does each variable granger cause one another and does the stock market work as a mediating variable for shock transmission?
3. Is there any moderating impact of oil price on the dynamic conditional correlation (DCC) between the stock market and exchange rate?
For data analysis, I have checked other relevant literature.
For research question 1, most of them used the VAR model to check the direct influence of variables on each other. For research question 2, most of them used VAR Granger Causality and determined if the stock market transmits the shock as a mediating variable or not. I haven’t found any paper on my 3rd research question but a paper suggested a technique to address it in their future research question. I am giving their exact quotation, “The moderating effect of oil can be estimated by using the NARDL framework for studying the direct influence of OP on the DCCs between SI and ER”.
But the problem is that, for my 1st and 2nd, I can’t use the VAR model as I have autocorrelation and heteroskedasticity which I can’t remove even after log transforming or log differencing the variable. I also can’t use VECM Model either as my variables are not co-integrated from the Johansen co-integration test. Therefore How can I conduct my VAR model removing autocorrelation and heteroskedasticity with any mathematical calculation. I insist to use VAR model. Do you have any idea. Give me guidance in R.

Your task is to, as an astrophysicist, rewrite to improve the proposal based on the reviewers' comments. You need to only reply the new version of proposal.
Reviewer comments: 「Strengths: Scientifically well motivated, a very careful pre-selected targets, and a good-designed project. Weaknesses: There are basically a couple of key issues that are not addressed in the science justification. First, radio sources in the VLASS catalog can be variables except AGN or Galactic stars, e.g., supernovae, tidal disruption events, long gamma-ray bursts, etc. The proposers exclude the possibilities of the selected sources to be AGN, but there is not specific information provided here about these radio sources. Are the sources really similar with the PRSes of FRB 20121102A and 20190520B in term of radio spectra, e.g., spectral index, variability? Otherwise, they can still possibly originate from the other transients. Much more rigorous evaluation of the selection criteria, that actually install some quantitative confidence of the likelihood that the selected sources match the definition of PRSs as defined in e.g. the Law et al. paper cited in the proposal, would improve the proposal. Second, the PRS-FRB association is not well established currently. Just as the proposers mentioned, it’s not conclusive that repeating FRBs have to be associated with PRSes. To date, there have been 8 repeaters localized to exact positions in their host galaxies, while only 3 repeaters are confirmed with PRS associations. Moreover, none of 12 localized apparent non-repeaters turn out to be associated with PRSes. Even though the PRS-FRB association does exist, there is much less than 50% chance to detect FRBs. Third, the sciences of non-detection case are unspecific. Even if we assume most of the selected sources are truly repeaters, it’s still very likely to miss detection considering many factors, such as, beaming angle of coherent emission, free-free absorption by ambient medium, emission band-limited for FAST, etc. In general, high-cadence observations are merely recommended once the sources have been confirmed to repeat. If there is no any clue of repetition, it’s non-sense to talk about active episode or non-Poissonian process. In fact, non-detection can neither establish nor rule out anything, the PRS-FRB association is still an open question. It is unclear how many FRBs the proposers expect to detect from their sample given the diversity in the 'on' and 'off' cycles of the FRBs with long-term periodicities. Technically, the authors may need to focus on a more selected targets, as the positions are accurate enough, no need for recording data for 19 beams.」

你好，下面是一个一维的多重网格代码，请你仔细领悟它的基本思想，在这个一维代码的基础上将其修改为二维的多重网格代码，用来解决f=2·π^2·sin(πx)·sin(πy)的泊松方程，其中使用高斯赛德尔迭代进行预光滑，使用双线性插值进行延拓，使用九点加权平均进行限制，并绘制误差随着迭代次数的变化图像，写出完整代码并作解释，最后，请告诉我最终的迭代次数和误差是多少。close all

I’m using an arduino mega with a keypad 4x4, a rtc3232, a LCD Screen 4x20, a button on pin 4, and 12 relays (from pin 34 to 46). I’m using those libraries : <Keypad.h>, <Wire.h>, <LiquidCrystal_I2C.h>, <DS3232RTC.h>, <Streaming.h>. I want to, when i press the button, to whow the following menu withsub menus and show it ont the lcd screen:
main menu : press ‘A’ to go to the sub menus « Relays Managing », press ‘B’ to go to the sub menu « Informations », press ‘D’ to quit the main menu and shut dows the screen. When you press A, it opn the first sub menu asking the number of the relay you want to manage (and collect this number with the keypad). Then, with this relay, thee sub menu propose to press keys : key ’A’ « ON/OFF », swith the relay statut (if it’s high, turn it to low and reverse), key ‘B’ « TIMER » rely high during a number of minuts (collected with the keybord, from 1 to 999 minuts), ‘C’ « Program with timer» (start hour and minuts collected with the keypad, then the functionning duration collected with the keybord). ‘D’ « exit » to quit the sub menu. The second sub menu (‘B’ information) have to show a second sub menu with « A – temperature info » (will show float numbers stocked in temp1, temp2, temp3, temp4 if pressed), « B – humidity info » (will show float numbers stocked in hum1, hum2, hum3, hum4 if pressed), « D-Quit » to live the sub menu.

model.fit(X_train,y_train,epochs=epochs,batch_size=batch_size,verbose=0)
loss, mae = model.evaluate(X_test, y_test)
loss, mae_train = model.evaluate(X_train, y_train)
train_scores.append(mae_train)
test_scores.append(mae)
train_score=mean(train_scores)
test_score=mean(test_scores)

return 0
else:
return score
# Define the Optuna study
study = optuna.create_study(direction='minimize')
# Optimize the hyperparameters
study.optimize(objective, n_trials=100)
Is it working for classification of y from 0:2 and y as regression? If not how to adjust it?

This code outputs to a text file the last recorded job in a sheet.
It gets the info from row 2 to row 10.
The code words perfectly.
How can I add to the code so that it first puts the value of B1 of the sheet named in wst into the text followed by the values of the last row 2 to 10
Dim sheetName As String
Dim rowValues As String
Dim filePath As String
Dim wst As Worksheet
Dim lastRow As Long
Dim i As Integer
A3A80 = False
sheetName = Me.Range("D" & Target.Row).Value
On Error Resume Next
Set wst = ThisWorkbook.Sheets(sheetName)
If wst Is Nothing Then
Exit Sub
End If
On Error GoTo 0
Set wst = ThisWorkbook.Sheets(sheetName)
lastRow = wst.Cells(Rows.Count, "J").End(xlUp).Row
For i = 2 To 10
rowValues = rowValues & wst.Cells(lastRow, i).Value & ","
Next i
rowValues = Left(rowValues, Len(rowValues) - 1)
filePath = "G:\Shared drives\Swan School Site Premises\PREMISES MANAGEMENT\SERVICE PROVIDERS\LastJob.txt"
Open filePath For Output As #1
For i = 2 To 10
Print #1, wst.Cells(lastRow, i).Value
Next i
Close #1
Shell "notepad.exe " & filePath, vbNormalFocus
End Sub

I'm using libgdx with box2d. Write me a util method that calculates the linear velocity needed to smoothly push a box2d body to a target position without overshooting the target.
Overshooting happens the the velocity returned is greater than needed to reach the target in the next physics timestep.
Note, maxSpeed is the maximum desired speed for the returned velocity, there is no minimum however. maxSpeed has no relation with overshooting.
Also note, you likely need to utilize delta time
This method should be able to handle high maxSpeed parameters I should be able to call this method every frame like so

I should be able to call this method every frame like so
Vector2 velocity = PhysicsUtils.velocityToPosition(body, target, maxSpeed);
body.setLinearVelocity(velocity);
Assume you have access to any information you need.
Note these you also have access to,
PhysicsSystem.STEP_FREQUENCY (when physics timestep = 1/60f, this = 60f)

I'm using libgdx with box2d. Write me a util method that calculates the linear velocity needed to smoothly push a box2d body to a target position without overshooting the target.
Overshooting happens the the velocity returned is greater than needed to reach the target in the next physics timestep.
Note, maxSpeed is the maximum desired speed for the returned velocity, there is no minimum however. maxSpeed has no relation with overshooting.
Also note, you likely need to utilize delta time
This method should be able to handle high maxSpeed parameters I should be able to call this method every frame like so

I will provide you disassembly from a computer game that runs in MS-DOS. The game was written in C with a Watcom compiler. Some library function calls are already identified. Explain the functions I give to you and suggest names and C-language function signatures for them, including which parameters map to which registers or stack values. Also suggest names for global values if you have enough context to do so and explain the data that is used.

Deconvolution Experiment for 1-D Filters
Use the function firfilt( ) to implement the following FIR filter w[n]=x[n]−0.9x[n-1] on the input signal x[n] defined via the MATLAB statement: xx = 256*(rem(0:100,50)<10); In MATLAB you must define the vector of filter coefficients bb needed in firfilt.
(a) Plot both the input and output waveforms x[n] and w[n] on the same figure, using subplot. Make the discrete-time signal plots with MATLAB’s stem function, but restrict the horizontal axis to the range 0 ≤ n ≤ 75. Explain why the output appears the way it does by figuring out (mathematically) the effect of the filter coefficients in (∗).
(b) Note that w[n] and x[n] are not the same length. Determine the length of the filtered signal w[n], and explain how its length is related to the length of x[n] and the length of the FIR filter.
Restoration Filter
The following FIR filter (FIR FILTER-2) [math]y[n]=\sum_{l=0}^{M}r^lw[n-l][/math] can be use to undo the effects of the FIR filter in the previous section.t performs restoration, but it only does this
approximately. Use the following steps to show how well it works when r = 0.9 and M = 22.
(c) Process the signal w[n] from w[n] =x[n] − 0.9x[n-1] with FILTER-2 to obtain the output signal y[n].
(d) Make stem plots of w[n] and y[n] using a time-index axis n that is the same for both signals. Put the stem plots in the same window for comparison—using a two-panel subplot.
(e) Since the objective of the restoration filter is to produce a y[n] that is almost identical to x[n], make a plot of the error (difference) between x[n] and y[n] over the range 0 ≤ n < 50.
Worst-Case Error
(f) Evaluate the worst-case error by doing the following: use MATLAB’s max() function to find the maximum of the difference between y[n] and x[n] in the range 0 ≤ n < 50.
(g) What does the error plot and worst case error tell you about the quality of the restoration of x[n]? How small do you think the worst case error has to be so that it cannot be seen on a plot?

}-> these are some of my classes seperated with ",". First i have a question. at album detail item composable i observe the album picture for all songs. Is this correct ? Because i wanted to have every songs individual picture at album detail item composable.

I am using the below autoencoder code to extra patterns from my business creddit portfolio as i am trying to predict charge off likley, is the code valuable to use or should i use a different one:
from keras.models import Model
from keras.layers import Input, Dense
from keras.optimizers import Adam
from sklearn.model_selection import train_test_split
# Split the data into training and validation sets
X_train, X_val = train_test_split(df_selected, test_size=0.2, random_state=42)
# Define the size of the encoded representation
encoding_dim = 64 # you can adjust this value
# Define the input layer
input_data = Input(shape=(X_train.shape[1],))
# Define the encoding layers
encoded = Dense(64, activation='relu')(input_data)
encoded = Dense(encoding_dim, activation='relu')(encoded)
# Define the decoding layers
decoded = Dense(64, activation='relu')(encoded)
decoded = Dense(X_train.shape[1], activation='linear')(decoded)
# Define the autoencoder model
autoencoder = Model(input_data, decoded)
# Compile the autoencoder
autoencoder.compile(optimizer=Adam(), loss='mean_squared_error')
# Train the autoencoder
autoencoder.fit(X_train, X_train,
epochs=50,
batch_size=256,

You are given a 0-indexed integer array nums representing the strength of some heroes. The power of a group of heroes is defined as follows:
Let i0, i1, ... ,ik be the indices of the heroes in a group. Then, the power of this group is max(nums[i0], nums[i1], ... ,nums[ik])2 * min(nums[i0], nums[i1], ... ,nums[ik]).
Return the sum of the power of all non-empty groups of heroes possible. Since the sum could be very large, return it modulo 109 + 7.
Example 1:
Input: nums = [2,1,4]
Output: 141
Explanation:
1st group: [2] has power = 22 * 2 = 8.
2nd group: [1] has power = 12 * 1 = 1.
3rd group: [4] has power = 42 * 4 = 64.
4th group: [2,1] has power = 22 * 1 = 4.
5th group: [2,4] has power = 42 * 2 = 32.
6th group: [1,4] has power = 42 * 1 = 16.
7th group: [2,1,4] has power = 42 * 1 = 16.
The sum of powers of all groups is 8 + 1 + 64 + 4 + 32 + 16 + 16 = 141.
Example 2:
Input: nums = [1,1,1]
Output: 7
Explanation: A total of 7 groups are possible, and the power of each group will be 1. Therefore, the sum of the powers of all groups is 7.
Constraints:
1 <= nums.length <= 105
1 <= nums[i] <= 109
TESTCASE: [2,1,4]

need to fix entity here and make it endlessly spawn from the right side by chaotically moving in progression with platforms to the left side and then they should simply disappear by reaching the left side of canvas. entities need to multiply in count of enities spawned with player progression or just some basic timer, and enities should shot some projectiles which affects player square physics a little. also, need to make basic projeciles to display. output minified code: class Platform{constructor(x,y,w,h){this.x=x;this.y=y;this.w=w;this.h=h}collidesWith(obj){if(obj.y+obj.h<=this.y)return false;if(obj.y>=this.y+this.h)return false;if(obj.x+obj.w<=this.x)return false;if(obj.x>=this.x+this.w)return false;const objAbove=obj.y+obj.h-obj.vy<=this.y;const objBelow=obj.y-obj.vy>=this.y+this.h;const objLeft=obj.x+obj.w-obj.vx<=this.x;const objRight=obj.x-obj.vx>=this.x+this.w;if(obj.vy>0&&objAbove&&!objBelow){obj.y=this.y-obj.h;obj.vy=0;obj.jumping=false;return true}if(obj.vy<0&&!objAbove&&objBelow){obj.y=this.y+this.h;obj.vy=0;return true}if(obj.vx<0&&objRight){obj.x=this.x+this.w;obj.vx=0;return true}if(obj.vx>0&&objLeft){obj.x=this.x-obj.w;obj.vx=0;return true}return false}}class Player{constructor(x,y,w,h){this.x=x;this.y=y;this.w=w;this.h=h;this.vx=0;this.vy=0;this.jumping=false}move(keys){const friction=.9;const gravity=1;if(keys[87]&&!this.jumping){this.vy-=20;this.jumping=true}if(keys[68]){this.vx+=5}if(keys[65]){this.vx-=5}this.vx*=friction;this.vy+=gravity;this.x+=this.vx;this.y+=this.vy;if(this.x<0){this.x=0}if(this.y<0){this.y=0}if(this.x+this.w>canvas.width){this.x=canvas.width-this.w;this.vx=0}if(this.y+this.h>canvas.height){this.y=canvas.height-this.h;this.vy=0;this.jumping=false}}}class Entity{constructor(x,y){this.x=x;this.y=y;this.size=20;this.vx=-2+Math.random()-4;this.vy=-2+Math.random()4;this.projectiles=[];this.cooldown=0}move(){this.x+=this.vx;this.y+=this.vy;if(this.x<0||this.x+this.size>canvas.width)this.vx=-this.vx;if(this.y<0||this.y+this.size>canvas.height)this.vy=-this.vy;this.cooldown;if(this.cooldown<=0){this.projectiles.push({x:this.x+this.size/2,y:this.y+this.size/2,vx:-3,vy:0});this.cooldown=3}for(let i=0;i<this.projectiles.length;i++){this.projectiles[i].x+=this.projectiles[i].vx;this.projectiles[i].y+=this.projectiles[i].vy}}collidesWithPlayer(player){for(let i=0;i<this.projectiles.length;i++){const proj=this.projectiles[i];if(player.x<proj.x&&proj.x<player.x+player.w&&player.y<proj.y&&proj.y<player.y+player.h){player.vx+=proj.vx2;player.vy+=proj.vy2;this.projectiles.splice(i,1);i}}}draw(ctx){ctx.fillStyle=“red”;ctx.fillRect(this.x,this.y,this.size,this.size);ctx.fillStyle=“black”;for(const proj of this.projectiles){ctx.fillRect(proj.x,proj.y,5,5)}}}class Game{constructor(canvas){this.canvas=canvas;this.ctx=canvas.getContext(“2d”);this.platforms=[];this.player=new Player(100,100,50,50);this.scrollSpeed=4;this.platforms.push(new Platform(0,canvas.height-50,50,10));for(let i=0;i<10;i++){this.createRandomPlatform();this.entities=[];this.entitySpawnCooldown=0}this.keys={};document.addEventListener(“keydown”,evt=>{this.keys[evt.keyCode]=true});document.addEventListener(“keyup”,evt=>{delete this.keys[evt.keyCode]});requestAnimationFrame(this.update.bind(this))}createRandomPlatform(){const x=this.canvas.width;const y=Math.random()*this.canvas.height;const w=50+Math.random()*150;const h=10;this.platforms.push(new Platform(x,y,w,h))}update(){this.player.move(this.keys);for(let i=0;i<this.platforms.length;i++){this.platforms[i].collidesWith(this.player);this.platforms[i].x-=this.scrollSpeed}this.player.x-=this.scrollSpeed;if(this.platforms[this.platforms.length-1].x<this.canvas.width-500){this.createRandomPlatform()}this.entitySpawnCooldown;if(this.entitySpawnCooldown<=0){this.entities.push(new Entity(canvas.width,Math.random()*canvas.height));this.entitySpawnCooldown=100}for(const entity of this.entities){entity.move();entity.collidesWithPlayer(this.player);if(entity.x+entity.size<0){this.entities.shift()}}this.ctx.clearRect(0,0,this.canvas.width,this.canvas.height);for(let i=0;i<this.platforms.length;i++){let p=this.platforms[i];this.ctx.fillRect(p.x,p.y,p.w,p.h)}for(const entity of this.entities){entity.draw(this.ctx)}this.ctx.fillRect(this.player.x,this.player.y,this.player.w,this.player.h);requestAnimationFrame(this.update.bind(this))}}let canvas=document.createElement(“canvas”);canvas.width=window.innerWidth;canvas.height=window.innerHeight;document.body.appendChild(canvas);let game=new Game(canvas);

this code extracts named entities from a PDF resume using the BERT model and stores them in a MongoDB database. It first parses the text from the PDF file, then extracts named entities using the BERT model. The named entities are then organized into a Python dictionary with predefined categories, and this dictionary is stored in a MongoDB database. The code demonstrates how to use the BERT model and MongoDB to extract and store information from PDF resumes.

act as a professional freelance developer and reply to this:
I will just have to rely on your expertise. The feedback I provided sometimes might be vague to you, but honestly i dont know how to describe it in a specific way. It's just a feeling. I appreciate you tried to take consideration of "light up tech inspiration", but I cant tell it is reflected honestly, but that's the right direction.
In terms of the font, I also need your recommendation as well. Maybe try those high tech company site's font

question : “Companies these days now have the option to control their users very well owing to the
introduction of token management systems that possess a well-developed database.
Features needed –
● This definitely assists in handling tokens in a more simple way
● Novices should get acquainted with this as it is one of the best SQL project ideas
they can begin with.”
make tables for token booking management system in mysql server code dbms
1. query to retrieve the no. Of tokens assigned to a user.
2. To retrieve the token status of any particular user, how many token genarated by that uaser and which tokens are expire.
3. updation on token tables with insertion of a new user.
4. view on the output of ex 1
5. list of all users who have tokens < say 3
etc.

I will provide you disassembly from a computer game that runs in MS-DOS. The game was written in C with a Watcom compiler. Some library function calls are already identified. Explain the functions I give to you and suggest names and C-language function signatures for them, including which parameters map to which registers or stack values. Also suggest names for global values if you have enough context to do so.

need to make properre entitities spawning function, so they can multiply by numbers after each entity is passing away through left side of canvas and disappears. need to make some factor on which the entities multiply by time as well. so, for example, one entitty is left canvas through left side and two entities are spawned from the right side, but need to make some factor on which it decides if one or two entities be spawned in each iteration, so they not rapidly spawn in swarms of entities on the next iteration in progression. so, the more time passed, the more chance that there will be more entities going from the right side to the left and shoting their physical projectiles to player's square while player trying to jump on platforms.: class

Generate an actual HTML CSS and JS game using alerts, confirm messages, console.log and others from these descriptions
Title: Pop-up Closer
Instructions:
There are 3 pop-ups that can appear. One is an annoying pop-up, one is a mine that you have to type close or else you get a BSOD, and one is Clippy pop-up, who says random sayings. But if he says the same as the mine pop-up, you had to type it but not get a BSOD. Closing a pop-up will award you 10 points, and double those points for the Clippy one.

}-> these are my classes seperated with ",". What i want to do is adding a favorite songs functionality. I want to add a heart icon into album detail item composable. Whenever user clicks for empty heart icon for a song basically that song will add to the favorites. Favorites page will be similar to the album detail screen because. I want same structure. But every item in favorites will have loaded heart icon since they are already added to the favorite. If user reclick to the loaded heart than that means it is no longer a favorite song so it will be removed from favorites page and also if user go back to that song's album detail item the heart icon will also be empty since it is no longer favorite. And if a song is in favorites then when user opens also album detail item the heart icon in it will be a loaded heart. Also adding and removing from favorites by clicking heart feature will work on album detail item too. The song in the favorites page will also be ready to preview or pause just like in album detail item composable. For the favorites page i actually thought about making a bottom bar, you can see it in the main activity even if it is not on use right now. I wanted a bottom bar with 2 icons one for favorites page and other for category->artist->artist detail-> album detail page chains . Show me how can i add this functionality to the project as i described. Show me necessary classes and code changes.

For this assignment, you will be designing a "Friends Movie Selection Advisor" that will suggest movies for
people to see with their network of friends, and friends of friends. The suggestions should be constrained to
suggest only movies that everyone in the group wants to see, or would like. Your program should work with
facts about who is friends with whom. To find a network of friends that might want to see a movie together, you
need to build a recursive set of friends and friends of friends. Although you will be given a small set of sample
data, make sure your code can work with an arbitrarily large network of friends. To keep things simple, we will
start by assuming that friendship is reflexive f(A,A), and transitive, (f(A,B),f(B,C) → f(A,C)) but
NOT a symmetric relationship (f(A,B) ↛ f(B,A)).
Friends
Encode the following sample information as a set of facts. Use lower-case for the names.
Chris is friends with Lee.
Dale is friends with Myrna.
Chris is friends with Spike.
Pat is friends with Chris.
Myrna is friends with Sean.
In this part, also define a recursive predicate friends/2 where friends(A,B) means that A is friends with B. This
predicate will be used for testing, so keep the exact name for this recursive predicate. You can call your base
level "fact" predicates anything you want.
Preferences
Encode the following sample information as a set of rules. Most of the rules should use information from the
movie database predicates described below.
Pat wants to see a comedy movie.
Sean likes adventure.
Dale is ok with anything.
Lee is ok with anything that Sean would not like.
Myrna wants to see a thriller movie.
Spike just wants to see something from this century (2000s).
Chris wants to see a comedy movie from the 1980s.
Sample Movie Data
To construct movie data, you may use IMDB web site. Add at least 70 movies similar to the following list. The
genres should be ‘animation’, ‘horror’, ‘drama’, ‘comedy’, ‘adventure’, ‘thriller’ and ‘romance’.
Movie_Genre(shrek, animation).
Movie_Genre(theShining, horror).
...
Movie_Year(shrek, 2001).
Movie_Year(theShining, 1980).
...
...
Movie Advisor
Define a suggest/2 predicate that will suggest a movie that a particular person, and all her friends. For
example:
?- suggest(chris,Movie).
Movie = .................................................................................
This predicate will be used for testing, so name it as given. Auxiliary predicates you can design and name as
you want

To achieve the favorites functionality, you need to make several changes to your app. I will guide you through the changes needed to be made to your classes.
1. Add a list of favorite songs in the PlayerViewModel:
val favorites = mutableStateOf<List<Song>>(emptyList())
2. Add functions to add and remove favorite songs in PlayerViewModel:
fun addFavoriteSong(song: Song) {
favorites.value = favorites.value.toMutableList().apply { add(song) }
}
fun removeFavoriteSong(song: Song) {
favorites.value = favorites.value.toMutableList().apply { remove(song) }
}
fun isFavorite(song: Song): Boolean {
return favorites.value.contains(song)
}
3. Update the AlbumDetailItem Composable to show a filled heart icon if the song is in the favorites list, and perform the add or remove operation when the heart icon is clicked:
IconButton(
onClick = {
if (playerViewModel.isFavorite(song)) {
playerViewModel.removeFavoriteSong(song)
} else {
playerViewModel.addFavoriteSong(song)
}
},
modifier = Modifier
.align(Alignment.CenterVertically)
.padding(8.dp)
) {
Icon(
painter = painterResource(id = if (playerViewModel.isFavorite(song)) R.drawable.heart_filled else R.drawable.heart_empty),
contentDescription = if (playerViewModel.isFavorite(song)) “Favorite” else “Not Favorite”,
modifier = Modifier.size(24.dp)
)
}
Make sure to create the “heart_filled” drawable resource.
4. Create the FavoritesScreen Composable similar to the AlbumDetailScreen:
@Composable
fun FavoritesScreen(navController: NavController) {
val playerViewModel: PlayerViewModel = viewModel()
val favorites by playerViewModel.favorites.collectAsState()
Scaffold(
topBar = { TopBar(title = “Favorites”) },
content = { padding ->
Column(modifier = Modifier.padding(padding)) {
LazyColumn {
items(favorites) { song ->
AlbumDetailItem(song, navController, playerViewModel)
}
}
}
}
)
}
5. Update MainScreen Composable to add Navigation for the FavoritesScreen:
composable(“favorites”) {
FavoritesScreen(navController)
}
6. Uncomment the BottomBar related code in the MainScreen Composable and make sure it navigates to the favorites screen when the heart icon is clicked:
@Composable
fun MainScreen() {
val selectedScreen = remember { mutableStateOf(0) }
val navController = rememberNavController()
Scaffold(
bottomBar = { BottomBar(selectedScreen.value, onItemSelected = { index -> selectedScreen.value = index }) },
content = { padding ->
when (selectedScreen.value) {
0 -> MusicCategoriesScreen(navController, Modifier.padding(padding))
1 -> FavoritesScreen(navController)
}
}
)
}
7. Update the BottomBar Composable to handle the navigation:
@Composable
fun BottomBar(selectedScreen: Int, onItemSelected: (Int) -> Unit) {
BottomAppBar {
BottomNavigationItem(
icon = { Icon(Icons.Filled.Home, contentDescription = null) },
selected = selectedScreen == 0,
onClick = {
onItemSelected(0)
}
)
BottomNavigationItem(
icon = { Icon(Icons.Filled.Favorite, contentDescription = null) },
selected = selectedScreen == 1,
onClick = {
onItemSelected(1)
}
)
}
}
With these changes, your app should now have a new Favorites screen accessible from the bottom bar, and you should be able to add and remove songs from the favorites by clicking on the heart icon.-> u suggested these and these are my currenct classes ->package com.example.musicapp.Interface
