如果节点超出范围,如何在 Xcode 场景套件中检索节点?



这是Scenekit代码,而不是sprite工具包。因此,我试图使用触摸开始方法中的盒子的名称访问它,在本例中是"盒子",但它超出了范围,我尝试使用与spritkit相同的技术,但它不一样。

   //BOX
    SCNBox *boxGeometry = [SCNBox boxWithWidth:10
                                        height:10
                                        length:10
                                 chamferRadius:0.3];
    SCNNode *box = [SCNNode nodeWithGeometry:boxGeometry];
    box.position = SCNVector3Make(0, 10, 0);
    boxGeometry.firstMaterial.diffuse.contents = [UIImage imageNamed:@"wood.png"];
    boxGeometry.firstMaterial.specular.contents = [UIColor whiteColor];
    boxGeometry.firstMaterial.shininess = 10.0;
    box.name = @"box";
    [scene.rootNode addChildNode:box];


-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [touches anyObject];
    CGPoint location = [touch locationInView:self.view];

    if (location.x > 160) {
    }
    else{
    }

}

在场景的rootNode上调用-childNodeWithName:recursively:
