I found a workaround for a problem that I was having with multiple projectiles, but I am wondering if I am sidestepping an issue with my approach. I currently have a move where 3 fire balls are shot from 1 command/animation. I initially tried to have each fire ball have its own hit/hurt animation, however, only the first fireball would affect the opponent. The other 2 would just pass through them and not do damage. My fix was to switch "total hits," in the collision options to 3 and to have the space between hits to be very small. This has solved my issue, but I am still confused on why the hits wouldn't damage/register before that.

Casting frame for each fire ball was set on a 1 frame delay from each other and all fire balls have the same settings. My only thought is that the other fire balls were going through the opponent because the previous hit was still in affect.
