[quote="deadeye":2pfqvb3p][quote="acegi":2pfqvb3p]this would allow me to express object "knockback" (like a character getting knocked slightely backwards when hit by an object without using sloppy physics...)[/quote:2pfqvb3p]
That would require some new conditions to be added to the platform behavior. Something like "Object is pushed away" with a dropdown for "From left," "From top," etc.
I think if this method of pushing platform objects away from solids rather than up through solids is implemented, I think "Object is trapped" -> "Horiz," "Vert" would be a useful condition to have. Like it's intersecting on both the left and right and can't be pushed either way. You could make squishing traps and stuff that way.[/quote:2pfqvb3p]
How about "Acts as physics object" with a variable that determines the force it can exert and can be exerted on it before it gets pushed away? Also, "Destroy if clips object" option for squishing.
