解决这个问题（以及其他许多问题）的最好和最快的方法是使用探查器。它将能够向您展示哪些方法（可能还有支持这一点的行）需要最长时间才能完成。一旦你缩小范围，你就可以找出如何解决这些问题 至于你发布的代码，我必须同意Dajaw的说法，冲突代码有很大的优化空间。获取纹理数据everyframe从来都不是一个好主意，应该在游戏开始时完成一次，并存储在变量中供以后使用 总的来说，我认为其余的都可以，但是看看分析器显示了什么。一些次要的结构问题（可以使用其他ifs代替ifs，事情可以处理得更好，等等）
我建议你读一下这篇文章，我之前问过一个简单的问题。你建议怎么读？看起来很棒！然而，我对这一点还很陌生（嘿，这就是为什么我一开始就寻求帮助，duh），我真的不知道像素图的部分，而且万能的互联网也没有向我透露。我可以问一下吗@哈罗。var playerMap=pixelMaps[player.PlayerTexture]代码给了我一个关于KeyNotFound的错误。我真的很感激你在这里为帮助我所做的努力！这意味着player.PlayerTexture不在pixelMap字典中，请确保您添加了它。我发现了错误，确保您的播放器已经启动，并且您可以执行
pixelMaps=pixelMaps（新[]{level0，level1，level2，level3，level4，level5，player.PlayerTexture}）或在需要时使用pixelMaps.add（player.PlayerTexture）添加它 public static uint[] Pixels(Texture2D texture)
