ios - SKScene:场景的界限

Question

我如何获得场景的边界？

我正在测试演示，并以这种方式初始化场景:

GameScene *scene = [GameScene unarchiveFromFile:@"GameScene"];
scene.scaleMode = SKSceneScaleModeAspectFill;

因此，当我点击屏幕时，我会记录:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (UITouch *touch in touches) {
        CGPoint location = [touch locationInNode:   self];
        NSLog(@"%f, %f", location.x, location.y);
    }
}

当我按左下键时，我得到大约300-0，而我期望是0-0。

如何获得上下左右的界限？我找不到类似的方法:

[scene getBounds]

Scene.frame打印:(0,0,1024,768)不对应!!

您需要将GameScene的大小设置为等于其SKView的大小。您可以在didMoveToView的GameScene中执行此操作:

-(void)didMoveToView:(SKView *)view {
    [super didMoveToView: view];
    self.size = view.bounds.size;
}

或者，您可以在实例化 GameScene时设置大小:

SKView * skView = (SKView *)self.view;
// ...

GameScene *scene = [GameScene unarchiveFromFile:@"GameScene"];
scene.scaleMode = SKSceneScaleModeAspectFill;
scene.size = skView.bounds.size;

[skView presentScene:scene];
