Question

我如何获得场景的界限？

我正在使用demo进行测试，并以这种方式初始化场景：

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

所以，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);
    }
}

当我按下左下角时我大约300-0而我期待0-0。

如何获得左下角的左上角？我找不到像这样的方法：

[scene getBounds]

Scene.frame打印：（0,0,1024,768）不对应!!

Answer 1

您需要将GameScene的大小设置为等于SKView的大小。您可以在didMoveToView的{{1}}中执行此操作：

GameScene

或者，您可以在实例化-(void)didMoveToView:(SKView *)view { [super didMoveToView: view]; self.size = view.bounds.size; }：

时设置大小

GameScene

Answer 2

像这样初始化场景：

 GameScene *scene = [GameScene sceneWithSize:skView.bounds.size];
 scene.scaleMode = SKSceneScaleModeAspectFill;

测试这样的坐标：

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

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

    /* Pressed node */
    SKNode *node = [self nodeAtPoint:location];

    NSLog(@"x - %f; y - %f", location.x, location.y);
}

SKScene：场景的界限
