I have two raycast to detect if my player has touched the ground but it detects all collision even on my enemies how can i make it so that it only will detect if i am touching the ground collison box.
here is my code for the raycast2d collision

func is_on_ground():
if raycast_down.is_colliding() or raycast_down2.is_colliding():
	return true

You can do this by changing your enemies collision layer. However their naming has changed in 3.0, which version of Godot are you using?

You can stop raycast from detecting enemies by moving enemies inside a different collision layer. So you will be able to tell your Raycast2D to only care about the environment (such as platforms and walls) and not enemies.

Take a look at the layer_mask and collision_mask properties, all physics objects have these.
They can be set in the editor, their property look like a bunch of checkboxes, each check box represents one layer.

The doc explains what collision layer and mask are: PhysicsBody2D — Godot Engine (stable) documentation in English
