Because I keep making mistakes and I don’t mean to amateur but here I am. Please I am in need of your professional help.
You add a prop and then use the slapping animation.
@add Plastic Cup Red to CHARACTER (I think that’s how it’s called, not sure though. Loo in the prop library)
(Then whatever happens when the character has the drink… and when the character you want to spill the drink on is coming near if it wasn’t)
And then just
@CHARACTER is slap_angry (Again not sure what is the exact name)
And it should do it.
When you don’t want the character to hold the drink just
@remove Prop from CHARACTER
If you want the shot for it to actually soar through the air, you would need an overlay for the cup.
