How to code Doom 4 Finishing moves with interactive animations

i know it will be hard, or at least harder then most things that do get questioned on this site. But I"m fairly confident in what i can achieve and getting this to work in the utmost, way i envision it. Your reply actually already helped me to an extent with knowing a couple more things that need to be done, actors being rotated, locations.

If i can make it so a character opens a door and you see the characters hand turn the door ■■■ and push or pull it open. the possibilities are endless.

really thank you for the reply DDemon!!
