This post is 3+ years old ... but I'm also looking for something similar. Hoped it would've been addressed in Stencyl by now ... but I can't figure out how to do it. Here's my situation ...
I'd like my actor to generate different particles (color, size, shape) depending on which tileset it collides with. I was hoping I could assign each tileset to a unique tile group to get this effect. Like this ... actor hits blue tile(s) and blue sparks create, fly and disappear. But if the same actor hits a red tile (from a different tileset) ... red sparks create, fly and disappear.
Is this possible? If not with tilesets, maybe with a different method?
Thanks!
