Gani Event? Function?

[scriptless]

Hello, sorry for asking this question but searching the forum I have found nothing.

I am looking to see if there is any event called when a player's gani is changed. Preferably to check if a player is swimming. Or if I would need to rescript the movement and add custom events when changing ganis.

I am looking for an alternative to having to use a timeout loop to check if a player is swimming.

Thanks,
scriptless

Edit:
Not to familiar with script's in ganis. I could add a script to the gani itself maybe? On created() and trigger a function in a weapon script, right?
