ios - 我的 Sprites 在 Sprite Kit 中使用 Swift 被压缩

Question

我正在使用 Sprite Kit 创建我的第一款游戏。这是一款 Flappy Bird 类型的游戏。左边的图片是今天早些时候的比赛。我最终创建了一个全新的项目。我复制了上一个项目的代码并将其粘贴到当前项目中。我也将与上一个项目完全相同的图像放入当前项目中。没有编译错误，除了游戏现在看起来像右图之外，一切都一样。如您所见，图像宽度较小。任何建议将不胜感激，如果您希望我提供此问题中的所有代码，请告诉我，谢谢。

这是射箭场景的所有代码:

Answer 1

要解决我的问题，我需要做的就是在我的 GameScene 文件中添加一行简单的代码。这是我在解决出现 ArcheryScene 的问题之前在 GameScene 文件中的代码:

welcomeNode?.runAction(fadeAway, completion: {
                let doors = SKTransition.pushWithDirection(SKTransitionDirection.Down, duration: 1.0)
                let archeryScene = ArcheryScene(fileNamed: "ArcheryScene")
                self.view?.presentScene(archeryScene, transition: doors)
            })

我所要做的就是在创建“archeryScene”之后添加这行代码:

archeryScene.scaleMode = .AspectFill

这使得图像“适合屏幕大小”。 Apple 使用的“.AspectFill”的确切描述是:

“计算每个维度的缩放因子，并选择两者中较大的一个。场景的每个轴都按相同的缩放因子进行缩放。这保证了 View 的整个区域被填充但可能会导致部分要裁剪的场景。”
