Area2D detects itself

gruen

Hello,

i have the following Porblem. the player can create some buildings while playing. that for i put a preview on the cursor. this preview has an area2d to detect if its colliding with some solide shapes. but unfortunately its detecting itself all the time. i already tryed to use a different layer and a different mask but that dosnt work. its detecting itself.

    func PreShow(): #zeigt das zu Platzierende element an der Maus an
	var childCount = get_child_count()
	if Globals.placeItem == true:
		if childCount == 0:
			whatToPlace = MAIS.instance()
			whatToPlace.add_to_group("DoNotCollide")
			whatToPlace.connect("body_entered",self,"CheckForCollide")
			
			add_child(whatToPlace)
		else:
			var xy = Globals.transformMousepositionToMap()
			var x = xy[0]
			var y = xy[1]

			whatToPlace.position.x = x
			whatToPlace.position.y = y
			if prePosition != Vector2(x,y):
				CheckForCollide(whatToPlace)
				prePosition = Vector2(x,y)
			if Globals.willCollideWithSolid:
				whatToPlace.modulate.r =3.0
			else:
				whatToPlace.modulate.r = 1.0
	if Globals.placeItem == false and childCount > 0:
		for i in get_children():
			i.queue_free()


func CheckForCollide(item):
	if item:
		if item != whatToPlace:
			Globals.willCollideWithSolid = true
		else:
			Globals.willCollideWithSolid = false

		
	print(Globals.willCollideWithSolid)

While more of a workaround than a solution, you could just check to see if the item its colliding with is itself and if it is, then ignore processing it. Something like this:

func CheckForCollide(item):
	if item == self:
		return
	if item:
		if item != whatToPlace:
			Globals.willCollideWithSolid = true
		else:
			Globals.willCollideWithSolid = false
	print (Global.willCollideWithSolid)
