I want to try to take advantage of the 3D space but the main focus is a 2D space, that’s why i want to know if there is a way to use the Y axis to move elements front and back.
Example: Super Mario 3 (NES/SNES/GBA), we could say that when Mario push down in the white blocks he is send to the back of the stage (the “Y axis” in my project)
I believe the plane constraints only lock the physics state so you should be free to use nodes like setActorLocation. In the case of jumping behind platforms, I would have the crouchjump look if I am standing on white block before shifting into new constraint plane; then, while falling, draw a linetrace back to the original plane to find an open space; when an open space is found, shift back into the original constraint plane.
I had created a bp that would bend the constraint plane as you ran along a spline. This would be compartmentalized around corners. But if I had mistakenly missaligned one of these bps, you could see the player slide back onto the intended plane. So movement can definitely be influenced by blueprints.
