For my game I'd like to have magic spells that crawl across the surface. Meaning specifically that they can move uphill/downhill and up/down slopes (but nothing too steep such as 60 degree + angles. Can't have them crawling up against walls or boundaries).
The problem is that the spell needs to be able to go through enemies and certain objects. If I set the collision to "Is Trigger" the spell will fall through the floor.
How can I get it to:
1. Move along the surface
2. Not fall/move through the surface
