How do I detect what layer a body collides with with code?
Also, the doc you used is from 3.2, currently I am using 4.2.

      Vickyboi In the lower left of the documentation page you can click on the version number to change it to the corresponding page for your version. To check collision layers in code you would use the collision_layer and/or collision_mask properties as explained on that page.

          What lines of code would I need?
          I read all of the doc, yet it only mentioned the properties, not how to utilize them.
          I tried tweaking the code provided in the doc, but I couldn't formulate a way to detect a collision layer.

          func _physics_process(delta):
    var collision_info = move_and_collide(velocity * delta)
    if collision_info:
        var collision_point = collision_info.position

          How would I modify this code to make it detect when I collide with a specific layer.
          Is there anything else I should be trying?

              Vickyboi You can call get_collider on collision_info and then check the collision_layer of the returned object. Something like:

                  var collision_info = move_and_collide(velocity * delta)
    if collision_info:
        var collider = collision_info.get_collider()
        collider.collision_layer # etc

                  It may be important to mention that I am trying to collide with tilemaps
                  I tried to print the print(collider.collision_layer), but it returned: Invalid get index 'collision_layer' (on base: 'TileMap').

                      Thanks! This video has revealed some very important details to solve the problem.
                      However, I cannot find how to grab the layer number in a 2d platformer setting, even after some heavy research.
                      I may have to utilize a different approach for interacting with tilemaps, any suggestions?

                          Vickyboi So in that video he used custom data layers (rather than collision layers) to flag tiles to trigger specific interactions, he shows how to set it up starting at around 2:10.

                            Would this approach work in a 2d side scrolling platformer?
                            I think I can do it now (hopefully). Just to clarify, I wouldn't need ALL of the code in the terrain detector, just the ones he shows?

                            I finally did it! Thank you for sticking with me through this process, I'm sorry for how annoying it might've been. I can finally continue my game!

                                Vickyboi Glad you got it worked out! And no need to apologize, I just didn't see your previous reply (looks like something went weird with the "@" and I didn't get a notification).

                                  That video is great, but I still need to get the collision layer, not custom data, so the vid doesn't really solve the problem
