I am developing a simple platformer, I have three types of tiles right now:

  • Floor: does nothing on collision.
  • Bad: makes the player lose the game.
  • Good: makes the player beat the game.

I am trying to detect the collision with this code I found:

extends RigidBody2D

func _process(delta):
    var tile = get_parent().get_node("TileMap").get_cellv(get_parent().get_node("TileMap").world_to_map(position))

The tile variable is supposed to contain the identifier of the type of tile the player is touching, but it doesn't, it always returns -1 (No exception or error, just -1).

I believe returning -1 means it isn't touching any tile, but it is.

This is using Godot 3.0 stable.

What am I missing?

Thank you for your patience.


I've found a way to make it work, I am not sure if this is the best possible solution but it works:

extends RigidBody2D

func _integrate_forces(state):
    var tilemap= get_parent().get_node("TileMap");  
    for i in range(get_colliding_bodies().size()):
        var tile_pos = tilemap.world_to_map(state.get_contact_local_position(i))
        var tile = tilemap.get_cellv(tile_pos)

This function is inside my player script. var tile will contain the type id of each colliding tile.
