雪碧试剂盒检测触点

Question

我有四个雪碧:球，物体，线和星星。我还界定了以下类别：

static const uint32_t ballCategory = 0x1 << 0; static const uint32_t objectsCategory = 0x1 << 1; static const uint32_t lineCategory = 0x1 << 2; static const uint32_t starsCategory = 0x1 << 3;

物业：

ball.physicsBody.categoryBitMask = ballCategory;
ball.physicsBody.contactTestBitMask = objectsCategory | starsCsategory;
object.physicsBody.categoryBitMask = objectsCategory;
object.physicsBody.contactTestBitMask = ballCategory;
star.physicsBody.categoryBitMask = starsCategory;
star.physicsBody.contactTestBitMask = ballCategory;
line.physicsBody.categoryBitMask = lineCategory;
line.physicsBody.contactTestBitMask = objectsCategory;

现在，在我的didBeginContact方法中(没关系)：

    if( ( contact.bodyA.categoryBitMask & lineCategory ) == lineCategory || ( contact.bodyB.categoryBitMask & lineCategory ) == lineCategory ) {

    score++;
    scoreLabelNode.text = [NSString stringWithFormat:@"%ld", (long)score];

}
    if( ( contact.bodyA.categoryBitMask & ballCategory ) == ballCategory || ( contact.bodyB.categoryBitMask & ballCategory ) == ballCategory ) {

    [self gameOver];


}

另一部分(这不起作用)：

if( ( contact.bodyA.categoryBitMask & starsCategory ) == starsCategory || ( contact.bodyB.categoryBitMask & starsCategory ) == starsCategory ) {

    score = score + 100;
    scoreLabelNode.text = [NSString stringWithFormat:@"%ld", (long)score];

}

我的错在哪里？我要:当球“接触”明星时，我得到100分。

代码中有一个错误：(starsCsategory)

ball.physicsBody.contactTestBitMask = objectsCategory | starsCsategory;
