[Threshold]

You need to set the animation to 'looping', so it won't stop after it's done playback. All you need to do is change the '0' to a '1' for the loop parameter in ApplyAnimation.

pawn Код:

forward DeadAnim(playerid);
public DeadAnim(playerid)
{
    OnAnim{playerid} = true;
    ApplyAnimation(playerid,"PARACHUTE","FALL_skyDive_DIE",3.5,1,0,0,1,0);
    return 1;
}

Then, once they do /acceptdeath or the FD arrives, you can ClearAnimations or apply another 'standing up' animation.
