SKScene：场景的边界

Question

如何获取场景的边界？

我与演示测试，我以这种方式初始化一幕：

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

所以，当我在屏幕上点击我登录：

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

当我按下左下角我得到大约300-0，而我期待0-0。

我怎样才能得到上下左右边界？我找不到像这样的方法：

[scene getBounds] 

Scene.frame打印：（0,0,1024,768）不相应！

Answer 1

您需要将GameScene的大小设置为等于其SKView的大小。您可以在您的GameScene的didMoveToView做到这一点：

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

或者，当你实例化GameScene您可以设置大小：

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

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

[skView presentScene:scene];

初始化的场景是这样的：

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

测试坐标是这样的：

-(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); 
}
