How do you.....
 

How do you make it so when a playerenters a level it plays a gani no matter what they are doing?

Do you mean change the player's gani or an NPCs?

FOR PLAYER

if (playerenters) {
setani ganiname,gfx used;
}

FOR NPC

if (playerenters) {
setcharani ganiname,gfx used;
}

an addition
 

for the player, you might want to freeze the player, or it will go back to walking unless you do this:

if (playerenters) {
replaceani walk,yourani; setani yourani; sleep (about the length of your ani); replaceani walk,walk;
}

:)

thanks
