Why is my Raycast detection not working?

  onready var raycast = get_node("RayCast2D")

func _physics_process(delta):
	var playerposition = get_parent().get_node("Player").position
	var coll = raycast.get_collider()
	if coll.is_in_group("player"):
		print("TIS BUT A SCRATCH")

The code is above. I’m getting the error “Attempt to call function ‘is _in _ group’ in base ‘null instance’ on a null instance” Does anyone know why this could be happening?

As per the official documentation, get_collider() might return null in case of no collision:

    Object get_collider ( ) const

Returns the first object that the ray intersects, or null if no object is intersecting the ray (i.e. is_colliding returns false).

You need to check why the collision is not happening first.

Nice, thanks, I added in an if raycast.is_colliding(): and that solved the crashes, Thanks for your help!
