使SKScene的背景透明不起作用......这是一个错误吗？

Question

有没有办法让SKScene的背景透明,并通过透明度将该场景呈现在另一个场景上.

想法是让所呈现的场景的背景如下:

self.backgroundColor = [SKColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:0.5f];

什么可以看到背后的场景变暗.但这样做并不奏效.背景呈现完全不透明.

有没有办法做到这一点？

Answer 1

在iOS 8中,您可以设置场景的SKView以允许透明度并将场景的背景颜色设置为具有透明度.然后会看到SKView背后的视图.

UIView *parentView = ...;
[parentView addSubview:backgroundView];
[parentView addSubview:skViewWithScene];
skViewWithScene.allowsTransparency = YES;
scene.backgroundColor = [UIColor clearColor];
[skViewWithScene presentScene:scene];

Answer 2

透明度仅适用于iOS 8,必须检查iOS 7

在ViewController中将透明度设置为:

SKView *skView = (SKView *)self.mySKView;
SKScene *skScene = [MyScene sceneWithSize:skView.bounds.size];
skScene.scaleMode = SKSceneScaleModeAspectFill;
skView.allowsTransparency = YES;
[skView presentScene: skScene];

在MyScene.m中将背景设置为清晰的颜色:

self.scene.backgroundColor = [UIColor clearColor];

@IBOutlet var gameScene: SKView!

func setupGameScene(){

    if let scene = SKScene(fileNamed: "GameScene") {
        scene.scaleMode = .aspectFill
        scene.backgroundColor = .clear
        gameScene.presentScene(scene)
        gameScene.allowsTransparency = true
        gameScene.ignoresSiblingOrder = true
        gameScene.showsFPS = true
        gameScene.showsNodeCount = true
    }
}
