UnityD性能消耗分析器

2、游戏。它为您报告在你的游戏的各个领域所花费的时间。例如，它可以 报告渲染、动画或在你的游戏逻辑花费时间的百分比。You can play your game in the Editor with P rofiling on, and it will record p erformance data.The P rofiler window then dis pl ays the data in a timeline, so you can see the frames or areas that sp ike (take more time) than others. By clicking

3、anywhere in the timeline, the bottom section of the Profiler window will dis play detailed information for the selected frame.在编辑器中，你可以将你的游戏在分析器运行着的状态下运行，它会记录性能数据。分析器窗口，在时间轴上显示数据，所以你可以看到帧或区域峰值（比其他需要更多的时间）。在时间轴中的任何地方按一下，分析器窗口的底部区域会显示选定的帧的详细信息。Note that p rofiling has toinstrument your code.
