Quote: "how does DBP know that there is an animation to play?"
Because your program knows which switch the character threw, so you simply play the appropriate animation frames that move the door limb. I think it would be easier to simply model the doors as limbs and programatically move the appropriate limb though...

Maybe I'm missing something... the animations are contained in the .X file
