What could possibly go wrong?Īs a trained professional you know the value of practice, so try this out on a toy project before you attempt a rescue operation at work. Or just hang on for the fun of a little tour into disassembled, jit'ed code. Until we get that feature properly done and release it, you can use the trick below. But it was not until my first Hack Week here, that I got to talk to the right people and realized why the trick works and how it may be used to create a proper way to break scripts in Unity ( sneak peek of my Hack Week project). Some years back, before joining Unity, I found a way to break a script that is stuck like this.

But usually only if you can guess the right place in the code to set a breakpoint. If you were lucky enough to have the debugger attached before running your game, you may be able to break it. Unity becomes unresponsive and you may have to kill the Editor entirely to get out of the mess. If you have experienced an infinite loop in your script code in Unity, you know it is quite unpleasant. And then there was the broken data structure traversed by an algorithm that assumed current = current.next would surely lead to an end eventually.

Another time a degenerate mesh sent a NaN right into an unsuspecting while(1) loop. Once it was the broken random function returning 1.000001 on impossibly rare cases. But from time to time, I’ve encountered them in sneaky variants. Infinite loops seems to be something that should be easily avoidable.
