使SKScene的背景透明不起作用......这是一个错误吗？ [英] Making a SKScene's background transparent not working... is this a bug?

问题描述

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。

Is there a way to make a SKScene's background transparent and present that scene over another one seeing thru the transparency.

想法是有所呈现的背景像这样的场景：

The idea is to have the background of the presented scene like this:

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

什么可以让人看到背后的场景变暗。但这样做是行不通的。背景呈现完全不透明。

what would allow to see the scene behind darken. But doing this is not working. Background is presented completely opaque.

有没有办法做到这一点？

Is there a way to do that?

推荐答案

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背后的观点。

In iOS 8, you can set the scene's SKView to allow transparency and set the scene's background color to have transparency. Then views behind the SKView will be seen.

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