sum := squareVal + cubeVal
fmt.Println("[main] sum of square and cube of", testNum, " is", sum)

}
```
Why is it printed like that ???
Output:
```
1.[main] main() started
2. [main] sent testNum to squareChan
3. [cube] reading
4. [square] reading
5. [square] before writing
6. [main] resuming
7. [main] sent testNum to cubeChan
8. [main] resuming
9. [main] reading from channels
10. [square] after writing
11. [cube] before writing
12. [cube] after writing
13. [main] sum of square and cube of 3 is 36
14. [main] main() stopped
```
2 questions:
1) Why after call "squareChan <- testNum" scheduler first check cube goroutine instead of square goroutine?
2) Why after call "cubeChan <- testNum" main goroutine not blocked?
Please can somebody explain by steps - How exactly scheguler switch between square, cube and main goroutines in this code?

Most likely the `int32_t * SIZE` in the `malloc` call. If you use a bit-shift like `SIZE << 2` instead, your code should be much faster and more efficient. |
Spring Data JPA doesn't support aggregate functions in queries using method names.
The suggested approach is to use `@Query` as mentioned in your question. Why do you consider it dirty? It isn't IMHO. |
Five batch jobs A, B, C, D and E arrive at a computer centre at almost at the same time. They have estimated running times of 10,6,2,4 and 8 minutes.

i am making a multiplayer game using Mirror, the premise of this action is simple :
if a player walks in front of a patrolling enemy, the enemy will start following the player, in a single player context it all works fine, however when in a multiplayer setting it all goes bad :
- The client player walks in front of the patrolling enemy
- The patrolling enemy goes to the host player's position
(this update only happens on the host's POV, nothing changes on the client side)
this is my patrolling code :
``` csharp

I'm encountering an issue with Hibernate where I'm getting the following SQL error:
Please help me to resolve error
SQL Error: 0, SQLState: 42P01
ERROR: missing FROM-clause entry for table "th1_1"
Position: 14
I'm working on a Spring Boot application where I'm using Hibernate for ORM mapping. I have entities defined for dx_entity and dx_temporary_hazard, and I'm using a join strategy inheritance between them.
I'm attempting to retrieve data using Hibernate's findAll method.
`@Getter
@Setter
@Entity
@Table(name = "dx_entity")
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "table_name", discriminatorType = DiscriminatorType.STRING)

}
@Entity
@Table(name = "dx_temporary_hazard")
@Setter
@Getter

public class TemporaryHazard extends DxEntity {
// Entity fields...
}`
**test controller:

this.temporaryHazardRepository = temporaryHazardRepository;
}
@GetMapping("/test")
public Page<TemporaryHazard> test() {
return temporaryHazardRepository.findAll(PageRequest.of(0,20));
}
}`
When we trigger /test controller, Quires performed in console:

We can see that "th1_1.pk_id" is wrong alias name in count query. Hence query failing to return result.

In regular regex style:
^0b([01]_?)*[01]$
The regex:
- `0b` literal "0b"
- `[01]_?` binary digit optionally followed by an underscore
- `(...)*` zero or more of
- `[01]` binary digit
See [live demo][1].
Expressed as RE2C (I think):
BINARY_NUM = "0b" ([01]"_"?)* [01];

You'd have to edit file `gradle/libs.versions.toml` and add in TOML format:
[versions]
androidx_media3 = '1.3.0'
androidx_compose_bom = '2024.03.00'
androidx_compose_uitest = '1.6.4'
# ...
[libraries]
androidx_media3_exoplayer = { module = "androidx.media3:media3-exoplayer", version.ref = "androidx_media3" }
androidx_media3_exoplayer_dash = { module = "androidx.media3:media3-exoplayer-dash", version.ref = "androidx_media3" }
androidx_media3_exoplayer_ui = { module = "androidx.media3:media3-exoplayer-ui", version.ref = "androidx_media3" }
androidx_compose_bom = { module = "androidx.compose:compose-bom", version.ref = "androidx_compose_bom" }
androidx_compose_uitest = { module = "androidx.compose.ui:ui-test-junit4", version.ref = "androidx_compose_uitest" }
# ...
And one can even bundle these (optional):
[bundles]
exoplayer = ["androidx_media3_exoplayer", "androidx_media3_exoplayer_dash", "androidx_media3_exoplayer_ui"]
Which means, you can't just copy & paste, but have to convert to TOML.<br/>
Be aware that for BOM dependencies, this only works for the BOM itself.<br/>
When there's no version number, one can use: `//noinspection UseTomlInstead`.
The names of the definitions of the default empty activity app are kind of misleading since they're not explicit enough, there `androidx` should better be called `androidx_compose`... because eg. `libs.androidx.ui` does not provide any understandable meaning (readability), compared to `libs.androidx.compose.ui`. Proper labeling is important there.

You can simplify your query and just use `STRING_AGG`, so you get rid of your subquery. By the way, please take care to always put the table alias before the column name, not only sometimes.
SELECT
p.post_id,
COALESCE(STRING_AGG(k.topic_id::varchar,','
ORDER BY k.topic_id),
'Vague!') AS topic
FROM Posts p
LEFT JOIN Keywords k
ON LOWER(p.content) LIKE '% ' || k.keyword || ' %'
OR p.content LIKE k.keyword || ' %'
OR p.content LIKE '% ' || k.keyword
GROUP BY p.post_id
ORDER BY p.post_id;
See this [db<>fiddle][1] with your data.
The fiddle also shows you could use `CASE` rather than `COALESCE` in your orignal query which would solve your issue too. The issue was `COALESCE` replaces `NULL` values, but you got an empty string, not `NULL`. Anyway, your previous query is far too complicated for your use case.
You might also be able to simplify those `LIKE` conditions and rather use a Regex approach. Since I don't use Pie DB and am not sure about regex functionality there, I leave this part up to you.

PHP's `nl2br()` function can convert newline characters to `<br>` tags. This will preserve the line breaks when displaying the text in HTML. You can further modify the code to remove any trailing `<br />` tags from each line. This can be done by using the `rtrim()` function in PHP, which removes specified characters from the end of a string.
```php
{!! Form::textarea('mline', isset($mline) ? rtrim(str_replace('<br />', "\n", nl2br(strip_tags($mline))), "\n") : null, ['style'=>'height: 113px;width:150%;','class'=>'p-2']) !!}
```
Here, `rtrim(..., "\n")` removes any trailing newline characters from the text. This will ensure no extra line breaks at the end of the text. |
I have to remove a student from a Sensei Pro course if they have completed the course. When they try to purchase the course again and WooCommerce generates an error preventing them from purchasing because they already have the course, I check if they have already completed the course, and if so, I remove them from the course. So far, I can get the course ID, which is the same as the page ID, but I can't get the course related to that product.

**Update** With `usmap >= 0.7.0` the issue is no longer reproducible as data objects are now returned as simple features.
``` r
library(usmap)
library(ggplot2)
set.seed(123)
# Merge state polygons with ranking data
state_map_rankings <- merge(state_map, state_rankings,
by.x = "abbr", by.y = "state"
)
# Create the ggplot2 map
ggplot(state_map_rankings, aes(
fill = ranking
)) +
geom_sf(color = "black") +
scale_fill_gradient2(
low = "red", mid = "white",
high = "green", midpoint = 0
) +
theme_void() +
theme(legend.position = "bottom")
```
<!-- -->
**Original answer**
The issue is that the points which define the polygon get connected in the order as in your data. However, the `merge` will reorder you data and the rows are no longer in the right order To fix that reorder or rearrange your data by both `group` and `order`:
``` r
library(usmap)
library(ggplot2)
# Merge state polygons with ranking data
state_map_rankings <- merge(state_map, state_rankings, by.x = "abbr", by.y = "state")
state_map_rankings <- state_map_rankings[order(state_map_rankings$group, state_map_rankings$order), ]
# Create the ggplot2 map
ggplot(state_map_rankings, aes(
x = x, y = y,
group = group, fill = ranking
)) +
geom_polygon(color = "black") +
scale_fill_gradient2(
low = "red", mid = "white",
high = "green", midpoint = 0
) +
theme_void() +
theme(legend.position = "bottom")
```
<!-- -->

11. [cube] before writing
12. [cube] after writing
13. [main] sum of square and cube of 3 is 36
14. [main] main() stopped
```
2 questions:
1) Why after call "squareChan <- testNum" scheduler first check cube goroutine instead of square goroutine?
2) Why after call "cubeChan <- testNum" main goroutine not blocked?
Please can somebody explain by steps - How exactly scheguler switch between square, cube and main goroutines in this code?

I have been asked in one of the Top company below question and I was not able to answer.
Just replied : I need to update myself on this topic
**Question :**
**If you create a composite indexing on 3 columns (eid , ename , esal ) ?**
- If i mention only eid=10 after where clause will the indexing be called ?
- If I mention only eid=10 and ename='Raj' will the indexing be called ?
- If I mention in different order like esal=1000 and eid=10 will the indexing be called ?
- If I mention in reverse order like esal = 1000 and ename = 'Raj' and eid = 20 will the indexing be called ?
Need a solution for this need with detail table representation with data how it does?

I gave it the Wikipedia article about Power BI. I then asked my Copilot a basic question like "What is Power BI?", and it said that it can't help me with that.
Either this thing is completely useless or I'm doing something wrong. For some reason, I didn't find any articles about this issue online.
Has anyone had this issue? How do you fix it? |

You should sort the list of integers in descending order and then iterate through it, adding each number to the list with the smaller current sum, like the following:
```python
import random
intList = []
for i in range(10):
intList.append(random.randint(10, 200))
listX = []
listY = []
intList.sort(reverse=True)
sumX = 0
sumY = 0
for num in intList:
if sumX <= sumY:
listX.append(num)
sumX += num
else:
listY.append(num)
sumY += num
print(f"listx = {listX} \nlisty = {listY}\n sum x = {sumX}, y = {sumY}")
```
## Edit
To ensure that both lists have exactly 5 elements and maintain balanced lengths, you can modify the algorithm to distribute the numbers based on the lengths of the lists. If one list has fewer than 5 elements, prioritize it adding numbers to that list until it reaches 5 elements.
Try this:
```python
import random
intList = []
listX = []
listY = []
for i in range(10):
num = random.randint(0, 5)
intList.append(num)
intList.sort(reverse=True)
sumX = 0
sumY = 0
for num in intList:
if len(listX) < 5:
listX.append(num)
sumX += num
elif len(listY) < 5:
listY.append(num)
sumY += num
elif sumX <= sumY:
listX.append(num)
sumX += num
else:
listY.append(num)
sumY += num
print(f"listx = {listX} \nlisty = {listY}\n sum x = {sumX}, y = {sumY}")
```

I have two identical C++ classes that are instantiated from within a lambda which is run in a separate thread. Below are the two classes:
```c++
class A : public C
{
std::thread thr;
void thrFunction(X &x)
{
while(atomic<bool>){
//long running process
}
}
public:
A();
int start(X &x)
{
thr = std::thread(&A::thrFunction, this, std::ref(x)); //Throwing Error C2672 at compile-time
return 0;
}
};
class B : public C
{
void thrFunction(X &x)
{
while(atomic<bool>){
//long running process
}
}
public:
A();
int start(X &x)
{
thrFunction(x); //blocking call
return 0;
}
};
````
These classes' objects are used from within another class `X`:
```c++
class X
{
A *a;
B *b;
public:
X();
void cleanup();
int callMembers()
{
a->start(*this);
b->start(*this);
}
};
````
This is how these classes are used:
```c++
int main()
{
X *api = new X()
auto lbda = [](X *api)
{
api->callMembers(); //meant to block here
api->cleanup();
}
std::thread(lbda, api);
while(true)
{
sleep(10);
}
}
````
This code doesn't compile and throws this error:
> C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\thread(60,14): error C2672: std::invoke': no matching overloaded function found
The error is due to the thread constructor call in `class A`.
I have tried to fix it by searching for a solution on the Internet, but to no avail. Almost all of the solutions suggested are changing the thread instantiation syntax, but nothing has worked so far.
After some changes, the compiler error changes to:
> C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.39.33519\include\memory(3434,35): error C2661: 'std::tuple\<void (__cdecl A::* )(X &),A *,X>::tuple': no overloaded function takes 3 arguments
No matter what I try, I cannot get it to compile.
Maybe there is something related to the class hierarchy which is causing this error? That is why I shared the whole structure of the involved classes and members.
Can someone please help me resolve this error? |
I've been enjoying the convenience of the Black Formatter extension in Visual Studio Code, especially its "Format on Save" feature for Python files. Being able to automatically format my code upon saving with Ctrl+S has significantly streamlined my workflow.
However, I've encountered a limitation when working with Jupyter notebooks (.ipynb files) in VSCode. While the Black Formatter seamlessly formats .py files on save, I've noticed that formatting code within Jupyter notebooks requires manually triggering the format command for each cell using Alt+Shift+F. This inconsistency in the user experience between .py files and .ipynb files disrupts the workflow and diminishes the efficiency gained from the "Format on Save" feature for Python scripts.
I'm reaching out to see if anyone has found a solution or a workaround to extend the "Format on Save" functionality to Jupyter notebooks within VSCode. Ideally, I'm looking for a method to automatically format all code cells in a notebook when saving the notebook file, similar to how it works for .py files.
Has anyone else experienced this issue or found a way to make code formatting as effortless in .ipynb files as it is in .py files within VSCode? Any advice, plugins, or settings recommendations that could help achieve this would be greatly appreciated.
In my quest to streamline my development workflow, I've successfully configured the Black Formatter extension in VSCode to automatically format Python (.py) files on save, using the following settings in my settings.json:
```json
"[python]": {
"editor.defaultFormatter": "ms-python.black-formatter",
"editor.formatOnSave": true
}
```
This setup works perfectly for Python scripts, automatically formatting them each time I press Ctrl+S, aligning with my expectations for a seamless and efficient coding experience.
Transitioning to Jupyter notebooks within VSCode, my expectation was to replicate this level of automation. Given the widespread use of notebooks for data science and machine learning projects, automating code formatting within these notebooks would greatly enhance productivity. I anticipated that either the same settings would apply or there would be a straightforward alternative for .ipynb files.
What I tried was to apply the same logic and settings, hoping VSCode would interpret and extend the "Format on Save" feature to the cells of Jupyter notebooks. I explored the VSCode and Black Formatter extension settings but found no direct reference or solution for applying automatic formatting to .ipynb files upon saving, similar to .py files.
What I'm seeking is either a confirmation that this functionality currently doesn't exist for .ipynb files in VSCode or guidance on a workaround. Perhaps a different configuration or an extension that bridges this functionality gap? Any shared experience, advice, or solution that would allow for automatic formatting of Jupyter notebook cells on save, enhancing the consistency and efficiency of the development process within VSCode, would be invaluable. |

Return a pointer to the `Node` of interest instead of updating the out parameter `head_dest`. The current implementation changes the original list. To create a new list you need to return a pointer to copy of the smallest node or NULL. To emphasize that I made the argument constant with `const Node *head`.
```
#include <stdio.h>
#include <stdlib.h>
typedef struct Node {
int val;
struct Node *pt_next;
} Node;
Node *linked_list_new(int val) {
Node *n = malloc(sizeof *n);
if(!n) {
printf("malloc failed\n");
exit(1);
}
n->val = val;
return n;
}
Node *linked_list_create(size_t n, int *vals) {
Node *head = NULL;
Node **cur = &head;
for(size_t i=0; i < n; i++) {
*cur = linked_list_new(vals[i]);
if(!head) head = *cur;
cur = &(*cur)->pt_next;
}
*cur = NULL;
return head;
}
void linked_list_print(Node *head) {
for(; head; head=head->pt_next)
printf("%d->", head->val);
printf("NULL\n");
}
void linked_list_free(Node *head) {
while(head) {
Node *tmp = head->pt_next;
free(head);
head=tmp;
}
}
Node *pairWiseMinimumInNewList_Rec(const Node* head) {
Node *tmp;
if (
(head && head->pt_next && head->val < head->pt_next->val) ||
(head && !head->pt_next)
) {
tmp = linked_list_new(head->val);
tmp->pt_next = pairWiseMinimumInNewList_Rec(head->pt_next ? head->pt_next->pt_next : NULL);
} else if (head && head->pt_next) {
tmp = linked_list_new(head->pt_next->val);
tmp->pt_next = pairWiseMinimumInNewList_Rec(head->pt_next->pt_next);
} else
tmp = NULL;
return tmp;
}
int main() {
Node *head=linked_list_create(7, (int []) {2,1,3,4,5,6,7});
Node* head_dest=pairWiseMinimumInNewList_Rec(head);
linked_list_print(head);
linked_list_free(head);
linked_list_print(head_dest);
linked_list_free(head_dest);
}
```
If you want you can compress the implementation by observing that it returns a NULL (base case) or a copy of a either the first or the 2nd node. The recursive call is either two nodes ahead or we are done:
```
Node *pairWiseMinimumInNewList_Rec(const Node* head) {
if(!head)
return NULL;
Node *tmp = linked_list_new(
(head->pt_next && head->val < head->pt_next->val) ||
(!head->pt_next) ?
head->val :
head->pt_next->val
);
tmp->pt_next = pairWiseMinimumInNewList_Rec(head->pt_next ? head->pt_next->pt_next : NULL);
return tmp;
}
```

The bellow Java Vector API code has a DoubleVector filled with doubles, named "A1".
I am trying to convert this DoubleVector (A1) to IntVector (RESULT), so far unsuccessful.
```
double[] v1 = {10237, 10709, 11340, 11468, 11771, 12003, 12196, 12456, 13904, 14557, 14636, 14811, 15337, 15468, 15719, 15990};
double[] v2 = {150, 171, 180, 183, 184, 289, 301, 306, 358, 449, 486, 539, 567, 605, 643};
int[] result = new int[v1.length];
var species = DoubleVector.SPECIES_PREFERRED;
for (int index = 0; index < v1.length; index += species.length()) {
var V1 = DoubleVector.fromArray(species, v1, index);
var V2 = DoubleVector.fromArray(species, v2, index);
DoubleVector A1 = V1.div(V2).pow(2);
//Create IntVector RESULT by the convertion of DoubleVector A1 to IntVector.
RESULT.intoArray(result, index);
}
```
EDIT 1:
After more research on the subject, the updated code is:
```
double[] v1 = {10237, 10709, 11340, 11468, 11771, 12003, 12196, 12456, 13904, 14557, 14636, 14811, 15337, 15468, 15719, 15990};
double[] v2 = {150, 171, 180, 183, 184, 289, 301, 306, 358, 449, 486, 539, 567, 605, 643};
int[] result = new int[v1.length];
var species = DoubleVector.SPECIES_PREFERRED;
for (int index = 0; index < v1.length; index += species.length()) {
var V1 = DoubleVector.fromArray(species, v1, index);
var V2 = DoubleVector.fromArray(species, v2, index);
DoubleVector A1 = V1.div(V2).pow(2);
//Create IntVector RESULT by the convertion of DoubleVector A1 to IntVector.
IntVector RESULT = A1.convert(VectorOperators.D2I, index).reinterpretAsInts(); // <--- I need help to write this line correctly.
RESULT.intoArray(result, index);
}
```
There is an error message related to the size difference between double and int, that says: `bad part number 4 converting Species[double, 4, S_256_BIT] -> Species[int, 8, S_256_BIT] (lanes are contracting by 2)`.

You can reduce your set of interfaces as `{ a: A; } | { a: A; b: B; }` is `{ a: A; b?: B; }`:
interface ButtonOnlyText extends React.ButtonHTMLAttributes<HTMLButtonElement> {
text: string;
}
interface ButtonOnlyIcon extends React.ButtonHTMLAttributes<HTMLButtonElement> {
Icon: React.FunctionComponent<React.SVGProps<SVGSVGElement>>;
iconProps?: React.SVGProps<SVGSVGElement>;
}
interface ButtonTextAndIcon extends React.ButtonHTMLAttributes<HTMLButtonElement> {
text: string;
Icon: React.FunctionComponent<React.SVGProps<SVGSVGElement>>;
iconProps?: React.SVGProps<SVGSVGElement>;
}
Then you can't declare `Button` as
function Button({ text, Icon, iconProps, ...buttonProps }: ButtonProps)
Simply because there are interfaces in your disjunction that don't have the props you're trying to access. Typescript will tell you that these properties are not defined.
All you can do is declare it as
function Button(props: ButtonProps)
And then have some code that'd work like this:
const buttonProps = restrict(props).toAllBut(["text", "Icon", "iconProps"]);
And query for the props you want to access like this:
if ("text" in props && "Icon" in props) // ButtonTextAndIcon
And handle all cases as you please. |

I have a NSString that has two characters.
The NSSring looks something like this
> FW
I use this code to capture the first character:
NSString *firstStateString = [totInstStateString substringToIndex:1];
This piece of code returns F, I would like to know how to return the second character to its own string using substringToIndex.

I have a data table I've imported into PowerBI from an csv that is a large list of exam results. Each row represents the details of when that particular exam was taken by a particular student. Some students will have taken the same exam more than once resulting in multiple rows for the same student/subject.
| SUBJECT | STUDENT | DATE |
| -------- | -------- | -------- |
| English | Fred | Feb |
| Maths | Stuart | May |
| Science | Fred | Feb |
| Maths | Simon | Mar |
| Science | Peter | June |
| English | Peter | June |
| English | Fred | Oct |
| Maths | Paul | June |
| Maths | Fred | Jan |
| English | Stuart | June |
I'm trying to find a query that will return a count of the unique number of students that have taken a particular combination of subjects. So, for the example above, how many students have taken both English **and **Maths?
The correct return would be **2** as only fred and stuart have taken both subjects.
I'm very new to DAX and have tried nesting a range of different statements but just can't figure this out? Nothing seems to get even close to the result needed. |

You need to set the selected value in OnValueChange() event like
const [selectedCourse,setSelectedCourse]=useState(state.courses[0]);
<Picker
style={styles.picker}
selectedValue={selectedCourse}
onValueChange={(itemValue) => {
setSelectedCourse(itemValue);
getUserScores(itemValue);
}}
>
{state.courses.map((course) => (
<Picker.Item key={course.name} label={course.name} value={course} />
))}
</Picker>

If I want to use borrowed parameters in ```tokio::spwan```, as in the following function, how to solve the error of "borrowed data escapes outside of function"?
```
async fn error(param: &str){
let _ = tokio::spawn(async move {
println!("string is {:?}", param);
}).await;
}
```
full error
```
error[E0521]: borrowed data escapes outside of function
--> src/main.rs:11:13
|
10 | async fn error(param: &str){
| ----- - let's call the lifetime of this reference `'1`
| |
| `param` is a reference that is only valid in the function body
11 | let _ = tokio::spawn(async move {
| _____________^
12 | | println!("string is {:?}", param);
13 | | }).await;
| | ^
| | |
| |______`param` escapes the function body here
| argument requires that `'1` must outlive `'static`
```
Since the database connection is passed as a borrowed parameter, I'm not quite sure how this can be resolved... |

I need a solution to my problem. i need a way for my navmesh_agent. to detect and follow a prefab clone instead of a gameobject already inside of the scene. to give some intel i am trying to add multiplayer to my zombie game, and as you may know to use multiplayer in unity you will need to spawn a new player each time incase of player joining.
ive tried, creating a prefab of the player, and deleting the one in the scene having the nav mesh straight up, follow the prefab starting runtime, and dragging the prefab into the scene. Unfortunately i am not able to think of another solution.
```
using UnityEngine;
using UnityEngine.AI;
public class ZomWalkerAI : MonoBehaviour
{
public GameObject Zom1DW;
public GameObject Zom1I;
public GameObject Zom1NB;
public Transform Playerpos;
public bool TouchingPlayer = false;
UnityEngine.AI.NavMeshAgent agent;
public bool inRange = false;
// Start is called before the first frame update
void Start()
{
agent = GetComponent<UnityEngine.AI.NavMeshAgent>();
Zom1DW.SetActive(false);
Zom1NB.SetActive(false);
Zom1I.SetActive(false);
}
void Update()
{
if (TouchingPlayer == true)
{
Zom1I.SetActive(false);
Zom1NB.SetActive(true);
Zom1DW.SetActive(false);
}
if (inRange == false)
{
Zom1I.SetActive(true);
Zom1NB.SetActive(false);
Zom1DW.SetActive(false);
}
if (inRange == true)
{
if(TouchingPlayer == false)
{
Zom1DW.SetActive(true);
Zom1I.SetActive(false);
Zom1NB.SetActive(false);
agent.destination = Playerpos.position;
}
}
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "Player")
{
inRange = true;
}
}
void OnTriggerExit(Collider other)
{
if (other.gameObject.tag == "Player")
{
inRange = false;
Zom1DW.SetActive(false);
