swift - 更改所有 SKTextures 的 SKTextureFilteringMode

Question

有没有办法为所有 SKTextures 将 filteringMode 属性分配给 SKTextureFilteringMode.nearest？除了单独分配给每个纹理。以下工作正常，但我宁愿不必遍历纹理，而只需为过滤模式设置默认值。这可能吗？

func walk () -> SKAction {

    let walkTexture1 = SKTexture(imageNamed: "walk1.png")
    let walkTexture2 = SKTexture(imageNamed: "walk2.png")
    let walkTexture3 = SKTexture(imageNamed: "walk3.png")
    let walkTexture4 = SKTexture(imageNamed: "walk4.png")
    let walkTexture5 = SKTexture(imageNamed: "walk5.png")


    let animationTextures: [SKTexture] = [walkTexture1, walkTexture2, walkTexture3, walkTexture4, walkTexture5]

    for texture in animationTextures {
        texture.filteringMode = SKTextureFilteringMode.nearest
    }

    let walkAnimation = SKAction.animate(with: animationTextures, timePerFrame: 0.3/5)

    return walkAnimation

Answer 1

在同一个循环中创建纹理和设置属性

让纹理 = (1...5).map {
让 texture = SKTexture(imageNamed: "walk\($0).png")
texture.filteringMode = SKTextureFilteringMode.nearest
返回纹理
}


或者只使用 forEach

设置属性

textures.forEach {
$0.filteringMode = .nearest
}
