在 SKScene 中设置按钮 [英] Setting up buttons in SKScene

问题描述

我发现 UIButtons 不能很好地与 SKScene 一起工作，所以我试图将 SKNode 子类化以制作一个SpriteKit 中的按钮.

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.

我希望它的工作方式是，如果我在 SKScene 中初始化一个按钮并启用触摸事件，那么该按钮将在我的 SKScene 中调用一个方法，当它被按下.

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.

如果有任何建议可以引导我找到此问题的解决方案，我将不胜感激.谢谢.

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

推荐答案

你可以使用 SKSpriteNode 作为你的按钮，然后当用户触摸时，检查它是否是触摸的节点.使用 SKSpriteNode 的 name 属性来标识节点:

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;
}

将节点添加到您的场景:

Add node to your scene:

[self addChild: [self fireButtonNode]];

处理触摸:

//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...
    }
}
