I kinda forgot about this thread, whoopsies.
Tbh I think a trigger overhaul could revolutionize the game and that its worth putting time into.
A couple things I'd like to see are:
1.) alternate ways to activate triggers, like damage thresholds, dismemberment, fractures, a speed threshold, a height threshold, (things that are already measured in some capacity by functions in the game), and dabarrett's suggestions as well.
2.) alternate trigger effects, like awarding points to tori or uke, dismembering&fracturing tori or uke, or applying a certain velocity to the object the trigger exists on (like you can kinda sorta do in nuthug's ingame hacking script), and the things you already suggested.
An update like this would be a huge breath of fresh air, and could flood the modding community with a ton of new ideas and applications.
