sprite-kit - 如何检测 SKShapeNode 是否被触摸？

Question

我创建了一个 sknodeshape。如何检测我制作的形状是否被触摸（点击）？

这是代码：（我已经解决了）

//metung_babi is the name of the SKShapeNode

UITouch *touch = [touches anyObject];
CGPoint nokarin = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:nokarin];

if ([node.name isEqualToString:@"metung_babi"]) {
    NSlog(@"touch me not");
}

我的错误是当我创建形状时，我在初始化之前放置了 SKShapeNode 名称。

Answer 1

实现触摸委托方法。然后，在 -touchesBegan: 方法中，提取触摸点并使用 [self nodeAtPoint:] 方法检索节点

Answer 2

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    /* Called when a touch begins */

    UITouch *touch = [touches anyObject];
    CGPoint location = [touch locationInNode:self];

    SKNode *yourNode = ....;
    CGRect yourNodeFrame = bowlNode.frame;

    if (CGRectContainsPoint(yourNodeFrame, location)) {

        //your node may be touched, check if it's your node
        SKNode *theNode = [self nodeAtPoint:location];

        if ([theNode.name isEqualTo:yourNode.name]) {
            //it's your node touched
        }
    }
}

方法nodeAtPoint返回值复杂。您可以查看文档以找到不同的情况
