Why this tileset isnt creating collision shapes when I use it in tilemap?

Maratonec

I'm trying to make a tileset with only two tiles, one that is solid and should make a collision shape and the other just black air

collisionset is the tileset

var tile_id = collisionset.get_last_unused_tile_id()

collisionset.create_tile(tile_id)
collisionset.tile_set_name(tile_id, "solid")

var shape = ConvexPolygonShape2D.new()
shape.set_points([Vector2(0, 0), Vector2(32, 0), Vector2(32, 32), Vector2(0, 32)])


collisionset.tile_add_shape(tile_id, shape, Transform2D(0, Vector2(0, 0)))

tile_id = collisionset.get_last_unused_tile_id()

collisionset.create_tile(tile_id)
collisionset.tile_set_name(tile_id, "air")

When I then use it in tilemap and enable seeing collision shapes in debug they are not visible.

If you add a RigidBody2D node with a sprite as a child, does it properly react to the solid tiles? It could be that the debug view doesn't show the collision shape because it's generated at runtime. I know that when I was working on voxel terrain in 3D, I couldn't use the debug view because collision geometry generated at runtime wasn't visible.

Nope it doesn't I tried it and it just goes thru it

I figured it out. It was because I wasn't setting any texture for it because I'm using it only for the collisions so I added blank texture to it and now it works as expected

Awesome, I'm glad you were able to figure out why it wasn't working! Thanks for sharing the solution! I would not have thought adding a texture would be a necessary step.
