我必须运行一个 19 秒的动画，每帧 466 帧是“1024x768”我正在使用 zwoptex 制作一个精灵表，但一张表是“4096 X 4096”，它只能容纳 15 帧。

我制作了多张纸，准确地说是 30 张，并用它们运行动画，但它有抖动，当我只使用 2 或 3 张纸时，它非常光滑。

这是我的代码

    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"];

    cache12=[CCSpriteFrameCache sharedSpriteFrameCache];
    [cache12 addSpriteFramesWithFile:@"Set_13.plist"];

    cache13=[CCSpriteFrameCache sharedSpriteFrameCache];
    [cache13 addSpriteFramesWithFile:@"Set_14.plist"];

    cache14=[CCSpriteFrameCache sharedSpriteFrameCache];
    [cache14 addSpriteFramesWithFile:@"Set_15.plist"];

    cache15=[CCSpriteFrameCache sharedSpriteFrameCache];
    [cache15 addSpriteFramesWithFile:@"Set_16.plist"];




    equ=[CCSprite spriteWithFile:@"m1.png"];
    [self addChild:equ z:5 tag:90 ];

每帧 466 帧的动画是“1024x768”

停在那儿！

问题是每个 4096x4096 纹理图集（spritesheets）都使用 64 MB 内存。在任何给定时间，只有 2-4 个（取决于设备内存）适合内存。

由于您按顺序缓存它们，因此您额外增加了加载时间，因为到它应该缓存纹理编号 3 或 4 时 cocos2d 将收到内存警告，并清除未使用的纹理 - 前几个纹理。

然后，当您开始动画时，它会在使用每个纹理图集时将其加载到内存中，因为此时唯一缓存的纹理可能是 8 到 10。同时其他未使用的纹理会被缓存，因为您不断收到内存警告.

你有两个选择：

  • 停止这种疯狂（™）
  • 也许最终可能通过使用 TexturePacker 并将纹理颜色深度降低到 16 位（RGB565 或 RGBA5551 - 将内存使用量减少一半）并将它们导出为 NPOT（轻微内存减少）和 .pvr.ccz（更快的加载和内存减少）可以改善情况。
