2020-02-27QualitySettings.SetQualityLevel 设置质量级别

public static void QualitySettings.SetQualityLevel(int index)

public static void SetQualityLevel(int index, [DefaultValue("true")] bool applyExpensiveChanges);

Description 描述
Sets a new graphics quality level.

设置新的图形质量级别。

Note that changing the quality level can be an expensive operation if the new level has different anti-aliasing setting. It's fine to change the level when applying in-game quality options, but if you want to dynamically adjustquality level at runtime, pass false to applyExpensiveChanges so that expensive changes are not always applied.

注意改变质量级别可能是个昂贵的操作，如果新级别有不同的抗锯齿设置。当应用游戏质量选项可以很好改变该级别，但是如果你想在运行时动态调整级别，通过applyExpensiveChanges 设置为false，这样昂贵的变化并不总是被应用。

When building a player quality levels that are not used for that platform are stripped. You should not expect a given quality setting to be at a given index. It's best to query the available quality settings and use the returned index.

建立的玩家质量级别是不被抛离平台的。你不应该期待指定质量设置在指定索引中。它最好查询可获取质量设置并使用返回索引。
