UnityD性能消耗分析器

2、游戲。它為您報告在你的游戲的各個領(lǐng)域所花費(fèi)的時間。例如，它可以 報告渲染、動畫或在你的游戲邏輯花費(fèi)時間的百分比。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.在編輯器中，你可以將你的游戲在分析器運(yùn)行著的狀態(tài)下運(yùn)行，它會記錄性能數(shù)據(jù)。分析器窗口，在時間軸上顯示數(shù)據(jù)，所以你可以看到幀或區(qū)域峰值（比其他需要更多的時間）。在時間軸中的任何地方按一下，分析器窗口的底部區(qū)域會顯示選定的幀的詳細(xì)信息。Note that p rofiling has toinstrument your code.

6、 exp ected.請注意，分析時必須檢測你的代碼。這檢測會對你的游戲性能有小小影響。通常情況下，這種開銷是足夠小，不會影響游戲的幀率。當(dāng)使用分析時，它是典型的考慮時間花費(fèi)在某些領(lǐng)域的比例（或百分比）。此外,為了提高性能，重點在游戲消耗的時間最多的那些部分。代碼更改前后比較分析結(jié)果，并確定您測量的改 進(jìn)。有時，您所做的更改來提高性能，可能對幀速率有負(fù)面影響；應(yīng)預(yù)計代碼優(yōu)化的意外的后果。怙 Pro-jlerAdd Profilerfe詁 Deep P = ofi：e LieM byncTinrie Active Profle；“FrmeiCPU Usage Pnrr - -carbdrre o
