Hi,

I have a problem that don’t found solution, I search and read a lot of post but nothing work.  
I have some SKSpriteNode with transparent area and I need detect the touch only on the non transparent area.

With…

> ```
> if let touchedBody:SKPhysicsBody = self.physicsWorld.body(at: pos) {   
> if let theSprite:SKSpriteNode = touchedBody.node as? SKSpriteNode {
> print(theSprite)
> }
> }
> 
> ```

Only work the last one SKSpriteNode and only at some locations inside the non transparent sprite.

With…

> ```
> for node in nodes(at: pos) {
> if (node.name != "gameboard"){    
> print("Node position \(node.position) name \(node.name)") 
> } 
> }
> 
> ```

I get all the nodes at location, but only is valid the non transparent.  
I try to get the alpha value of the texture but I’m blocked… ☹

Any other way to solve this? What I’m doing wrong?
