I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:
Engine.h:
#pragma once
#include "Window.h"
#include "Renderer.h"
#include "Scene.h"
class Engine
{
public:
Engine();
~Engine();
void Run();
void Shutdown();
private:
void Initialize();
void MainLoop();
void Update(float deltaTime);
void Render();
Window window;
Renderer renderer;
Scene scene;
};
Engine.cpp:
#include "Engine.h"
#include "Terrain.h"
#include <iostream>
Engine::Engine()
{
Initialize();
}
Engine::~Engine()
{
Shutdown();
}
void Engine::Run()
{
MainLoop();
}
void Engine::Initialize()
{
// Initialize window, renderer, and scene
window.Initialize();
renderer.Initialize(window.GetWindow());
scene.Initialize();
VkDescriptorSetLayout descriptorSetLayout = renderer.CreateDescriptorSetLayout();
VkDescriptorPool descriptorPool = renderer.CreateDescriptorPool(1); // Assuming only one terrain object
Terrain terrain(0,10,1,renderer.GetDevice(), renderer.GetPhysicalDevice(), renderer.GetCommandPool(), renderer.GetGraphicsQueue());
terrain.GenerateTerrain(descriptorSetLayout, descriptorPool);
scene.AddGameObject(terrain.GetTerrainObject());
float deltaTime = window.GetDeltaTime();
}
void Engine::MainLoop()
{
while (!window.ShouldClose())
{
window.PollEvents();
float deltaTime = window.GetDeltaTime();
Update(deltaTime);
Render();
}
}
void Engine::Update(float deltaTime)
{
scene.Update(deltaTime);
}
void Engine::Render()
{
renderer.BeginFrame();
scene.Render(renderer);
renderer.EndFrame();
}
void Engine::Shutdown()
{
// Clean up resources in reverse order
scene.Shutdown();
renderer.Shutdown();
window.Shutdown();
}
Can you please check the code for any potential memory leaks? If you find any, please tell me the changes required to fix them.

LUA I've got a chance table which has a label, value which is the chance of getting that rareity adds up to 1, and the average price. The requiredhourly is how much money the chances need to average per hour. The timeTaken is how much time is taken between each chance in seconds. I want the timetaken to refresh everytime a chance happens
simulate running for a day (24 hours) and then print the hourly, how many jobs are done per hour and how many chances are recived.
then loop playing around with the chance value (can't go over 1) and repeat until you get close to the required hourly can go up to 50000 but can't go below 35000
local chances = {
{label = 'Rare', value = 0.7992, avp = 700},
{label = 'Mythical', value = 0.1598, avp = 1500},
{label = 'Legendary', value = 0.0320, avp = 3000},
{label = 'Ancient', value = 0.0064, avp = 1000},
{label = 'Exceedingly Rare', value = 0.0026, avp = 125000}
}
local requiredhourly = 40000
local timeTaken = math.random(30, 60) + 7 -- seconds

}
LUA
AVP is average price per rareity
value is the chance of hitting
between 0-1
required to make at least 40000
and no more than 55000
it takes math.random(30,60) + 7 seconds between every chance attempt
randomize the number after every chance
simulate running for an hour and then print the money made per hour and what was gotten
if the money made wasn't within the requirement play around with the value in the chance table simulate again and repeat until within the rage
the total of the value can't execde 1 so lower chances rase others until you reach the desired output

I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:

std::shared_ptr<Pipeline> Renderer::GetPipeline() {
return pipeline;
}
The code seems to hang at this line of code in the Renderer::BeginFrame method:
vkBeginCommandBuffer(currentCommandBuffer, &beginInfo);
It does this after renderering several frames, but then just stops progressing past this line. Any ideas of what the issue could be?
Can you please check the code for any potential memory leaks? If you find any, please tell me the changes required to fix them.

please write my assignment for me "In this exercise you'll work with the Wisconsin Breast Cancer Dataset from the
UCI machine learning repository. You'll predict whether a tumor is malignant
or benign based on two features: the mean radius of the tumor (radius_mean)
and its mean number of concave points (concave points_mean).
The dataset will split into 80% train and 20% test. The feature matrices will
assign to X_train and X_test, while the arrays of labels are assigned
to y_train and y_test where class 1 corresponds to a malignant tumor and
class 0 corresponds to a benign tumor. To obtain reproducible results, you
also defined a variable called SEED which is set to 1.
Now that you will fit your first classification tree, it's time to evaluate its
performance on the test set. You'll do so using the accuracy metric which
corresponds to the fraction of correct predictions made on the test set.
• Read in the dataset "heart_disease_patients.csv" into a
variable called heart_disease.
• Print out the first ten rows of the data using head(), and check
that all variables are a form of numeric data (integer or double).
• Run the k-means algorithm on the data"

I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:

It does this after renderering several frames, but then just stops progressing past this line. Any ideas of what the issue could be?

Add a method in java swapTwoNodes to SinglyLinkedList class . This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapTwoNodes method in diffrent location of linklist. Hint: You may need to traverse the list.
also methos should get two element and find those nodes based on the element,and also methode is able to swap any nodes in the link list,

I’m building a video game engine using C++ as the coding language and Vulkan for graphics. I am trying to set up a generic renderer using Vulkan that is flexible and will render objects based on a vector that is supplied to it. The renderer will also handle the creation of the window using GLFW and use GLM for all relevant math calls. I am using the ASSIMP library to load 3d models and animations.
Here is a portion of the code:

The code seems to hang at this line of code in the Renderer::BeginFrame method:
vkBeginCommandBuffer(currentCommandBuffer, &beginInfo);
It does this after renderering several frames, but then just stops progressing past this line. The application completely stops at this point. Any ideas of what the issue could be?

write a dart function solve which takes input (seq, sub), generates a list of integers 0 to seq - 1 (total length seq),
then returns a list with all possible subsequences in a form of list (returns list of list of integers). do not use recursion
and try to cache all subsequences up to length sub
example : for inputs 6, 4 there are 15 items in a list, each of them is a list of 4 integers like [0, 1, 2, 3] or [1, 3, 4, 5]
