Alrighty, this seems to be a tough one.
Following paths from the pathfinding behaviour seems to ignore collision polygons.
I figured that a way to fix this would be to add the solid and the push out solid behaviour to the red cars.
The solid behaviour on its own doesn't seem to fix it.
ok i'll try this.
ok firstly i confused what do you mean by push out solid behavior. Google it, and found rex plugin, attach it and work like a charm. Thanks man!
But just adding those two behaviors caused weird movement of the cars. I eventually learned that you added the solid behaviour to quite some UI elements.
I don't know why you did that and I also don't know where that would be necessary, but I disabled those solid behaviours and that made the car's behaviours work and let them collide the way they need to.
lol, i just thinking to make the cars still on the stage and not in the bottom of controller, so player can see.
also not overlap the ui element on top. Any idea for this rather than using solid element ?
