Scene2d |在30個角色上調用rotateBy在android上導致低fps

我有一個遊戲，我的對象總是圍繞中心點旋轉。問題是，當我一次調用20多個演員的rotateBy時，fps從60 fps下降到30。這是正常行爲嗎？如何旋轉30名演員導致這樣的FPS下降？Scene2d |在30個角色上調用rotateBy在android上導致低fps

編輯：我也應該想到，每個演員都有一個身體，並且燈具被銷燬並重新創建每一幀（因爲演員改變大小）。

編輯這裏是代碼，這被稱爲每個演員的每個幀。

private void createFixtures(boolean remove) { 

    if (remove) { 
     if (fixture_inner != null) { 
      if (body.getFixtureList().contains(fixture_inner, false)) {

      } 
     }

       body.destroyFixture(fixture_outer); 
      } 
     }

您的演員是否使用Drawable繪製UI元素，還是直接繪製TextureRegions？某些Scene2d.UI元素在旋轉時會爲每個Actor導致批處理刷新。如果您的元素不是UI元素，請避免Drawable類並直接繪製TextureRegions。我沒有與Box2D的經驗知道你在那裏做什麼是一個沉重的行動。避免在渲染循環中使用Java'new'關鍵字，因爲這可能會導致大量垃圾回收。 – Tenfour04

請顯示一些代碼。具體來說就是創建和旋轉方法。 – IronMonkey

如果你破壞並重新固定裝置的每一個幀，你會做每秒約本次1800。與其摧毀並重新創建每一幀，您可以獨立於幀速率摧毀和重新創建燈具（即每秒10次，相當於30名演員每秒300次）。

這將顯着減少遊戲中發生的處理量，並且可以在大小之間進行插值，以便向用戶呈現流暢的動畫。

這會使性能差異變大嗎？ – XPatStudios

但是，這是行不通的。我試過這種方法，燈具落在演員身後。 – XPatStudios
