I've had an issue for a while that I normally found a work-around for, but I'm still rather curious; When I have an event such as :
if ROCK on collision with FLOOR
Create ROCK death sprite
Destroy ROCK
It doesn't seem to work right if 2 rocks hit the floor at the same time (it will destroy both of them, but it won't create a rock death sprite on both). I've noticed this on other occasions as well:
if ENEMY is playing animation "Shoot" and = frame 3
Create Projectile
If 2 enemies are on screen, playing the animation simultaneously, only one will shoot (usually the first on screen). However if I offset the animation by 1 frame, both shoot the projectile fine.
I'm just trying to wrap my head around why this is happening.
