let's say for example:
i have Character A, and canonicaly he has a big grudge on Character B.

how can i set a Text variable in Character A, that when Character B is present as an oponent, a special entrance animation plays

(for example: frame 1 to 50 holds the normal entrance and 52 fowards, holds the alternate entrance, so the idea is make a condition with a variable that stores the name of the oponent characters in game, and if match, the animation jumps to the special one.)
