[Scripting Question] Syntax for double formregister

So I recently found Vendily's script to update the sprite positionning of different forms, though it needs to define a "getMetricOffset" but I want to use also : to make it learn other moves.

How can I combine these procedures?

Maybe this can help you (check my post):

ok so close the first with },
thank you it works!

I realized with it that the attack animations are occuring depending on the altitude of the poke, which looks a bit bad with thunderbolt for example (the one from reborn)
