在動畫中的混亂2d

Question

我必須運行一個19秒的動畫與466幀每幀是「1024x768」我使用zwoptex來製作一個精靈表，但工作表是「4096 X 4096」，它只能容納15幀。

我已經制作了多張單張紙，準確地說是30張，並且與他們一起運行動畫，但它有一些混亂，我只用了2張或3張相當平滑的紙張。

這裏是我的代碼

cache=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache addSpriteFramesWithFile:@"Set_1.plist"]; 

    cache1=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache1 addSpriteFramesWithFile:@"Set_2.plist"]; 

    cache2=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache2 addSpriteFramesWithFile:@"Set_3.plist"]; 

    cache3=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache3 addSpriteFramesWithFile:@"Set_4.plist"]; 

    cache4=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache4 addSpriteFramesWithFile:@"Set_5.plist"]; 

    cache5=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache5 addSpriteFramesWithFile:@"Set_6.plist"]; 

    cache6=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache6 addSpriteFramesWithFile:@"Set_7.plist"]; 

    cache7=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache7 addSpriteFramesWithFile:@"Set_8.plist"]; 

    cache8=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache8 addSpriteFramesWithFile:@"Set_9.plist"]; 

    cache9=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache9 addSpriteFramesWithFile:@"Set_10.plist"]; 

    cache10=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache10 addSpriteFramesWithFile:@"Set_11.plist"]; 

    cache11=[CCSpriteFrameCache sharedSpriteFrameCache]; 
    [cache11 addSpriteFramesWithFile:@"Set_12.plist"];

動畫與466幀每幀爲 「1024×768」

停在那兒！

問題是，您的每個4096x4096紋理地圖集（spritesheets）都使用64 MB的內存。只有2-4（取決於設備的內存）將在任何給定的時間適應內存。

由於您按順序對它們進行緩存，因此您還需要增加加載時間，因爲到了應該緩存紋理編號3或4時，cocos2d將收到內存警告，並清除未使用的紋理 - 第一對紋理。

然後當你開始動畫時，它會在每次使用紋理圖集的時候加載到內存中，因爲那個點上唯一的緩存紋理可能是8到10個。同時，其他未使用的紋理會被緩存出來，因爲你不斷收到內存警告。

你有兩個選擇：

• 停止這種瘋狂（™）
• 也許可能通過使用TexturePacker和減少紋理顏色深度16位最終（RGB565或RGBA5551 - 精簡了一半的內存使用）並將它們導出爲NPOT（輕微的內存減少）和.pvr.ccz（更快地加載內存減少）可以改善這種情況。
