Question

更多的是关于框架本身（特别是 AssetManager ）的一般问题，而不是关于代码的问题。

当我注意到游戏加载状态中的进度条在某个时候下降百分比时，我一直在开发自定义加载器，以缓存我的纹理地图集的轮廓效果。是我的加载器，需要加载依赖项：基本图集和着色器（以及用于深度纹理的另一个图集）。

我的装载机通常看起来像这样（在Kotlin中）：

class OutlineLoader(
    resolver: FileHandleResolver
) : AsynchronousAssetLoader<OutlineAtlas, OutlineLoader.Parameter>(resolver) {
    override fun loadSync(manager: AssetManager, name: String, 
                          file: FileHandle, params: Parameter): OutlineAtlas {
        val sourceAtlas = assetManager.get<TextureAtlas>(name)
        val depthAtlas = assetManager.get<TextureAtlas>(params.depth)
        val shader = assetManager.get<ShaderProgram>(params.shader)

        return OutlineAtlas(sourceAtlas, depthAtlas, shader)
    }

    override fun getDependencies(name: String, file: FileHandle, 
                                 params: Parameter) =
            Array<AssetDescriptor<*>>().also { array ->
                listOf(
                        AssetDescriptor(name, TextureAtlas::class.java),
                        AssetDescriptor(params.depth, TextureAtlas::class.java),
                        AssetDescriptor(params.shader, ShaderProgram::class.java)
                ).forEach(array::add)
            }


    ...
}

因此，我正在排队一些资产，以后再使用它们。 AssetManager的Logger输出确认。然而，进展达到25％，然后达到20％；增至60％，然后增至33％。我插入了debug-print语句，以查看每次assetManager.update()调用后的加载进度，就像这样：

[AssetManager] Queued: sprites/sprites.atlas, foo.bar.OutlineAtlas

[DEBUG] Loading: 89%
[AssetManager] Loaded: 405.7238ms sprites/sprites.atlas, foo.bar.OutlineAtlas

在搜索源中，我不知道这是故意的还是我盲目地做一些愚蠢的事情？（我也没有在Wiki中找到有关该主题的内容。）

编辑：调试打印语句看起来像这样：

if (!assetManager.update()) {
    val progress = "${assetManager.progress * 100f}%"
    Gdx.app.debug("[DEBUG]", progress)
} else { ... }

在Java中只是AssetManager.getProgress()。

LibGDX资产依赖性降低进度
