Recently, I made a very dumb mistake that caused Unity to crash my computer. I could move the mouse sometimes, but everything else became completely unresponsive, leading to me having to shut off my PC.
What happened: I had an object, let's say an arrow, that could collide with another object, let's call it spawner. When the arrow collides with the spawner, it's supposed to destroy the arrow that activated the spawner. The spawner would then, as the name might imply, spawn more arrows. The problem was that I forgot to temporarily disable to collision on the newly spawned arrows, meaning that as soon as they would spawn inside the spawner's collision box, they'd spawn more arrows, and those arrows would spawn more arrows, and those arrows would... you get the idea. It was a very stupid mistake I realized the moment I hit play, but it was too late.
Now, I know that was entirely my fault, but I was wondering if you could prevent Unity from sending your PC into a coma like that? (Besides not making a dumb mistake like that, of course...) I'll be honest, I kind of expected Unity would have some sort of fail safe for this kind of error. Is there a way to limit the object count for example?
