How to make wall collision with staticbody2d & collisionshape2d ( using an area2D for player with collisionshape2d as a child ) in GODOT?

Question

I wanted to know if I can make a player with area2d with a child collisionshape2d and then make a collision with my walls having a node of staticbody2d

which has two childs in it of collisionbody2d

but as area2d doesnt know how to collide ig, what would your suggestion to make the collision happen between them..

I don't area_entered is any useful here.. area_touched might be useful but doesnt exist.. but there is oneway collision option in the collisionshape2d property.. is that option for that use?

Thanks! please help me understand better..

I tried to use layers but they didn't work for me
