blocks not acting as solid with solid behaviour on them

hi!

im making a game where the background is the floor, and everything is 3D. the character moves around on the floor/ background, and the 3d blocks around it are walls of a maze. to do this, I made the blocks solid, and the player is controlled with the wsad keys. however, bc the character moves around on the background(floor) not the blocks, it doesn't have the platformer behaviour. this allows it to move thu the solid blocks, or at least i think it does. any ideas on how i could fix this so that the player doesn't run thru the solid blocks?

don't really understand. anyway, did your character is "solid" too?

Solid only works if your character is controlled with behaviors like 8direction, Platform, Car etc.

If you are moving the character with events by changing its x/y coordinates, then Solid object will not stop it. In this case you'll have to add additional conditions like "Character overlapping wall at offset" to check if it can move there.

thankyou for helping! and i tried adding 8 direction and solid behaviors to my character, but this did not help it.
