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.
Answer
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...
}
}
