Well, simply put, first you need the lua compiler for Bully, which Mad will release later after finalizing some stuff and the lua tutorials.
Then, you have to set button commands for Jimmy so that the "action node" that pertains to the animation you're looking for is executed.
Example:
if IsButtonPressed(2, 0) then
ExecuteActionNode(gPlayer, "/Global/Generic/GenericWallSmoking", "Act/Anim/GenericSequences.act")
