Setting up buttons in SKScene

Question

I'm discovering that UIButtons don't work very well with SKScene, So I'm attempting to subclass SKNode to make a button in SpriteKit.

The way I would like it to work is that if I initialize a button in SKScene and enable touch events, then the button will call a method in my SKScene when it is pressed.

I'd appreciate any advice that would lead me to finding the solution to this problem. Thanks.

you could use a SKSpriteNode as your button, and then when the user touches, check if that was the node touched. Use the SKSpriteNode's name property to identify the node:

//fire button - (SKSpriteNode *)fireButtonNode {     SKSpriteNode *fireNode = [SKSpriteNode spriteNodeWithImageNamed:@"fireButton.png"];     fireNode.position = CGPointMake(fireButtonX,fireButtonY);     fireNode.name = @"fireButtonNode";//how the node is identified later     fireNode.zPosition = 1.0;     return fireNode; } 

Add node to your scene:

[self addChild: [self fireButtonNode]]; 

Handle touches:

//handle touch events - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {     UITouch *touch = [touches anyObject];     CGPoint location = [touch locationInNode:self];     SKNode *node = [self nodeAtPoint:location];      //if fire button touched, bring the rain     if ([node.name isEqualToString:@"fireButtonNode"]) {          //do whatever...     } }
