Make a balloon wait until completion with a script call?

[Banjo]

Using the normal Event option, you can make the game wait until a balloon completes its animation, but I need to use a script call for this since I'm using a variable for the event id. This works fine, but the game doesn't pause for the balloon to finish and I can't figure out how to make it do so using this scripting method.

My script snippet I'm using is:
$game_map.events[$game_variables[571]].balloon_id = 1

Can someone please tell me what I need to add to this script make the game wait for the balloon to finish animating?

Thanks!

Add this

Fiber.yield while $game_map.events[$game_variables[571]].balloon_id > 0

Thanks so much!
