while loop without break crashes Unity

Hello I am having trouble with a while loop. I have two while loops within a while loop. The code looks something like this:

While (x)
{

While (y)
{

!y;
break;​

}
While (!y)
{

y;
break;​

}
if (!x)
{

break;​

}​

break;
}

I want the code to run the through the main while loop until x is false. However Unity crashes unless I put in the final break ,thereby breaking from the main while loop when I don't want to break from it. Why cant/won't unity just keep running the while loop until X is false and thereby leaving the loop when I want it too. Hope my question is clear.

 

What part of infinite loops don't you get? The problem is in your code, what you're doing here is really bad code.

 

Lol hippo. I literally read the title and thought the same thing.

Here beatniq,
Your issue is that you're never actually setting x to false.
Explanation:

Code (CSharp):

1.  
2. While (x) //YOU NEVER SET X TO FALSE DURING THE LOOP
3.     {
4.         While (y)
5.         {
6.             !y; //YOU CAN'T SET A BOOLEAN THIS WAY, AT LEAST NOT IN C#.
7.             //BEST TO DO y = false;
8.             break;
9.         }
10.         While (!y)
11.         {
12.             y;
13.             break;
14.         }
15.         if (!x)//THIS WOULD NEVER HAPPEN, AS NOTHING HAS SET X TO FALSE
16.         {
17.             break;
18.         }
19.         break; //BREAK DOES NOT MEAN TO STOP THE WHILE LOOP, JUST BREAK OUT OF _THIS_ INSTANCE.
20.         //BUT THE SECOND IT BREAKS, IT HAPPENS AGAIN BECAUSE X IS STILL NOT SET TO FALSE.
21.     }
22.  
23.  
24.  

Try this:

Code (CSharp):

1.  
2. private bool x = true;
3.     private bool y = true;
4.     private bool z = true;
5.  
6.     while(x)
7.     {
8.         print(x);
9.         while(y)
10.         {
11.             //DO STUFF HERE
12.             y = false;
13.             print(y);
14.             break;
15.         }
16.         while(!y && z)
17.         {
18.             //DO STUFF HERE
19.             z = false;
20.             print(z);
21.             break;
22.         }
23.         while(x && !y && !z)
24.         {
25.             //DO STUFF HERE
26.             x = false;
27.             print("CLOSED OUT X");
28.             break;
29.         }
30.     break;
31.     }
32.  

 

if x is a boolean, and you never change its value inside the while loop to something other than it... the loop will go forever.

How would it ever change?

If you want this to be a set of code that repeats from frame to frame. Then you need to be putting this in a coroutine and yielding null at the end of the while loop.

 

Some people seem to be under the impression that "while" loops somehow run over multiple frames. Thinking this, they're under the impression that kicking off a while loop and then doing something elsewhere that would set their check to false is valid.

There are certain environments where that could be the case, but Unity's main thread isn't one of them.

 

I'm feeling you don't know what rhetorical questions are.

Considering I answered my question in the following sentence with the very same context that you bring up.

 

What a nice moderator really helping my homie out here.

 

Wow. What a f*ng vipers' nest. Thanks for nothing.
