How to cancel running a game?

so I accidently created an endless loop at the beginning of the game so this thing wasn't going away

I had to force quit unity and re-open it btw my pc is very slow so this takes awhile.
Is there a way to cancel without closing all of unity?

 

Nope. When you create an infinite loop like that, the process locks up the main thread and doesn't afford you an opportunity to jump in and tell it to stop. The only thing you can do is terminate the process and restart it.

Don't worry... we've all done it.

 

ok thank you.

 

If you find yourself doing this frequently, you could add code which automatically ends the loop. I do this when I'm troubleshooting an infinite loop, or I'm writing a loop which depends on me not breaking some other code somewhere else, which I might forget about the potential issue months later. Example:

Code (csharp):

1. int loops = 0;
2. while(variable < 10)
3. {
4.  
5.     //something here that was supposed to eventually get variable under 10, but actually never does
6.  
7.  
8.     //check if we're stuck in an infinite loop
9.     loops++;
10.     if (loops >= 10000)  //check if we've run this loop 10k times already
11.     {
12.         Debug.LogError("Oops I did it again -Britney");
13.         break;  //ends the infinite loop
14.     }
15. }

I generally favor using loops like foreach instead, since they are not capable of becoming infinite loops.

 

Thank you! I will definitely use this.
