My character is falling off a platform(I followed the runner
the “controller” collision type is static, group: geometry, Mask: player
“player” collision type is kinematic, group: player, mask: geometry
tried to remake it again still falling

Hard to tell what’s wrong. Can you double check that all scripts are added? Also double check collision groups and masks. Another thing to try is to set a breakpoint on the first line of the on_message function and see if it gets called at all.
That looks better, but the game object is scaled and the runtime shape doesn’t look like in the editor. The explanation can be seen when we look at the shape itself:
The shape is 20x20 pixels, which corresponds to what we see at runtime. The size of collision shapes aren’t scaled with the game object scale (there’s a ticket for this, but it’s not at the top of our list). You should set the size of the collision shape directly on the shape.
@Erik_Angelin and @mats.gisselson: We need to make sure that the editor doesn’t scale the shapes. I’ll create a ticket.
No, currently no way to prevent that, but the issue I linked should make sure that the visualisation in the editor matches the behaviour of the engine.
