Spritekit - 不从 SKTextureAtlas 加载 @3x 图像 [英] Spritekit - not loading @3x images from SKTextureAtlas

问题描述

由于我的示例项目被删除(我认为这会更容易测试)，我将发布一些代码和图像来说明我的观点.

Since my sample project was deleted (I thought this would be much easier to test), I will post some code and images to illustrate my point.

这里是示例图片

我的地图集设置:

我的启动图像设置:

我将这些精灵添加到我的场景的代码

The code where I add these sprites to my scene

override func didMoveToView(view: SKView) {
    let texture = SKTextureAtlas(named: "scenery")
    let test = SKSpriteNode(texture: texture.textureNamed("test"))
    test.position = CGPoint(x: self.size.width/2, y: self.size.height/2)
    self.addChild(test)

}

这些是我的结果:

iPhone 5 模拟器:

iPhone 5 simulator:

iPhone 6 plus 模拟器:

iPhone 6 plus simulator:

我已尝试更改启动图像以使用资产目录.然后 iPhone 6 plus 似乎升级了 2 倍屏幕.它仍在加载 2x 图像，但将其放大.

I've tried changing the launch image to use the asset catalog. Then the iPhone 6 plus seems to upscale a 2x screen. It's still loading the 2x image, but scales it up.

我需要它来加载我的 3x 图像并使用我的 2x 图像进行缩放.

I need it to load my 3x image and be to scale with my 2x image.

Gabuh 在下面的回答为我指明了正确的方向.在一个新项目上工作.但是，如果我将他的解决方案用于我真正的 SpriteKit 项目，我的 3x 图像不会缩小.它们比应有的大 3 倍.

Gabuh's answer below pointed me in the right direction. Works on a new project. However, if I use his solution for my real SpriteKit project my 3x images don't get downscaled. They are 3x bigger than they should be.

推荐答案

如果您正在使用一种新的方式来创建图集，它现在似乎可以工作了.重要的是 Deployment target 应该 >= 9.0 ...

It seems to be working now if you are using a new way to create atlas. Important thing is that Deployment target should be >= 9.0 ...

选择Assets.xcassets并点击+号创建一个新的精灵图集:

Select Assets.xcassets and click to + sign to create a new sprite atlas:

选择New Sprite Atlas"选项并添加@2x 和@3x 资产:

Choose "New Sprite Atlas" option and add @2x and @3x assets :

然后在代码中这样做:

let sprite = SKSpriteNode(texture: SKTextureAtlas(named: "Sprites").textureNamed("test"))
sprite.position = CGPoint(x: frame.midX, y: frame.midY)
addChild(sprite)

提示:

如果您在模拟器上进行测试，请在尝试之前重置模拟器的内容和设置以清除缓存.

If you are testing on Simulator, reset Simulator's content and settings to clear the cache before you try this.
