ios – SKTextureAtlas如何按顺序加载纹理

概述我使用SKTextureAtlas(.atlas文件夹)来存储我正在使用的动画的帧.我已经对frame.1.png,frame.2.png等帧进行了编号 – 总共有10帧. 我注意到我的动画看起来很糟糕,即使在我的图形程序中预览的帧看起来很棒.我NSLoged出来,发现它正在以随机顺序加载地图集！我假设它至少会遵循捆绑文件顺序.如何在不自行排序数组的情况下使用捆绑订单.我还将@ 2x图像与其余图像 我使用SKTextureAtlas(.atlas文件夹)来存储我正在使用的动画的帧.我已经对frame.1.png,frame.2.png等帧进行了编号 – 总共有10帧.

我注意到我的动画看起来很糟糕,即使在我的图形程序中预览的帧看起来很棒.我NSLoged出来,发现它正在以随机顺序加载地图集！我假设它至少会遵循捆绑文件顺序.如何在不自行排序数组的情况下使用捆绑订单.我还将@ 2x图像与其余图像放在一起,还是创建一个单独的图集？

SKTextureAtlas *sleighAtlas = [SKTextureAtlas atlasnamed:@"sleigh"];NSArray *texturenames = [sleighAtlas texturenames];NSMutableArray *sleighTextures = [NSMutableArray new];for (Nsstring *name in texturenames) {    NSLog(@"texture: %@",name);    SKTexture *texture = [sleighAtlas texturenamed:name];    [sleighTextures addobject:texture];}

它打印出来：

谢谢！

解决方法 可能texturenames属性包含纹理名称无序.而不是使用快速枚举用于(;;)：

for (int i=0; i < sleighAtlas.texturenames.count; i++) {    Nsstring *texturename = [Nsstring stringWithFormat:@"santaAndSleigh.%d",i];    [sleighTextures addobject:[explosion2Atlas texturenamed:texturename]];}

虽然如果你将@ 2x图像放入sleighAtlas中,这种方法可能不会起作用.
