I know a similar question has been asked before about this topic but here is my problem. I am using the following simple code to touch and SKNode.
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
let touch = touches.first as UITouch!
let location = touch.locationInNode(self)
let node = self.nodeAtPoint(location)
I then remove the touches node with the following:
node.removeFromParent()
Now, my problem is that the image of the node I am touching is small. Therefore it is very hard to accurately register a touch. I do not want to make the image bigger. This wouldn't be a problem but the nature of my game is such that I:
1) Cannot use another invisible SKSpriteNode ontop of my image SKSpriteNode to increase the registered touch area because each image has a unique name so I need that specific node to be touched and removed.
2) I cannot give the invisible SKSpriteNode the same name as the image SKSpriteNode because then only the invisible SKSpriteNode would be removed on touching.
3) I have tried to load a new SKSpriteNode into the original image SKSpriteNode to increase the touchable area, but once again, on touching, only the invisible SKSpriteNode gets removed, not the image SKSpriteNode which I want.
So, how can I increase the touchable area? Is there a way to maybe:
1) Remove all nodes associated with the node that is touched? This would then work if I put an invisible SKSpriteNode inside the original node to increase the touchable area. If they had the same name. But I have already tried "node.removeAllChildren()"......didn't work.
2) Detect a touch and the closest possible image near that touch is the image that the code in TouchesBegan gets use on? This would also work for my situation.
Any other suggestions? Cheers :)
-------------------------------UPDATE---------------------------
The following code below works! If I touch the invisible SKNode, then both the invisible and Original SKNodes disappear. However, for whatever reason, the original SKNode always appears infront of the invisible SKNode. I cannot fix this?
let original = SKSpriteNode(imageNamed: "original")
original.size = CGSize(width: 50, height: 50)
original.zPosition = 0
let invisible = SKSpriteNode(color: UIColor.redColor(), size: CGSizeMake(70, 70))
invisible.position = CGPoint(x: CGRectGetMidX(self.frame), y: CGRectGetMidY(self.frame))
invisible.alpha = 1.0
invisible.zPosition = 1
invisible.name = original.name
invisible.addChild(original)
self.addChild(invisible)
