i am making a player with tank movement (left and right to rotate, up to go toward angle and down to go backward angle), i make it with custom movement behavior, but when i want to make a collision with another object, the player don't detect it and through it. either, the player objects and the "wall" object have a mask collision and solid attribute, but it seem like both object don't collide each other
the code is this
