Hi! I’m using Unreal Engine 4.8.3 and I am making a 2D side platform game using Paper2D things.
I noticed that when my main character collides with other characters, their Y location can change and eventually they drop off into abyss. Setting physics constraints to XZ Plane or independently locking Y axis has no effect whatsoever on the actual Y location during game play. How I can eliminate all Y axis movement during game play?

A simple workaround would be to reset Y = 0 every tick for your sprite, but there is probably a cleaner solution.

Thanks. That’ll do.
