You can check if something is in a specific radius of something else.
Here's a radius function I shared ages ago - it's for checking if mouse cursor is within a specific radius, but it can be edited for other things; however, I think I shared a radius script on the VS discord a little while back that covered additional things.
There's also a function called isPointInsidePolygon, but I don't know how taxing it would be on the engine to loop that function - especially on something as complex as a character with multiple animation frames & dynamically generated interaction polygons. I'm also not sure if you can actually access the polygon table for characters.
