wha ? wha ? you... want the crate to explode, but you wanna play an animation with it ?
i don't understand, emmm... so the crate receive damage, play animation and explode ? well i'm sure it can be done, but... you don't want any kind of different explosion effect right? coz that ain't goona happen (fpsc issue), humm i think i'm starting to get you, you shot the thing, the thing reacts... and them boom !!!!! okay o got it, you need to go change the fpe file in the box's entity bank folder, open the fpe file and set explodable from 0 to 1, that might make sure it blows up after destroyed, ok, now the script, what you need is to make the script check if the entity have received a certain ammount of damage, and if i did, execute the animation you want, i'm sure you can do it if you try, any question, call the drunk guy behind the keyboard, just don't... scream....
