所以，和其他人一样，我一直在使用libgdx开发一款针对android os的游戏。我真的很喜欢使用我的个人艺术（photoshop画笔）而不是像素艺术。好吧，实际上我正在尝试融合2因为我们都知道android没有足够的内存来显示我想要使用的一些艺术。
例如：我有很多背景，512x512彼此相邻，构成整个“第一阶段”，看似多达12个以上的图像，每个图像大约是100k。这对Android很重要，并且显着降低帧速率，低于30 fps，这使我无法在场景中添加更多图像，我将需要来做。
问题：添加“背景”图片和背景Doodads的 方式是什么？
Kb（大小）有多大不应该过去？
我将它们作为Sprite加载而不是纹理，是好还是坏？
背景图片保存为.png 512x512 8bit，是好还是坏什么会更好？
texturePacker是否可以为性能做任何事情，我甚至应该纹理包装这些512x512和更大的文件？
顺便说一句，我没有打包背景图片...
我是否必须使用像素艺术和较小的图像尺寸才能在Android上创建完整的侧边滚轮？
我知道有很多问题，我试图解释我的困境，所以你会理解它作为一个整体...... 将所有这些问题都视为一个问题：
我已经在这个游戏上工作了7个月了，知道我有时候会越过这座桥，我已经做好了，我会说引擎已经接近完成，意思是，地图/游戏编辑器，角色机制/能力，游戏机制（水平障碍/要做的事情等），goomba和boss技能/能力/ AI，故事，前景动画（64x64,64x128图像没问题，即小文件大小），项目，菜单，IT都准备好了使用除了我有多个大背景大小的问题....
请欣赏任何链接，文章，教程......我已经走得足够远，知道如果我做错了，我可能要重做很多STUFF ....
我想要一个20多个小时的侧卷轴，在这个巨大的游戏中，我需要做些什么呢？

你的drawblocks函数每次调用时都会调用new textureregion，你每次都在创建一个新对象。您应该只调用new一次来创建对象，并在调用drawblocks时引用该对象。
创建在创建屏幕时调用的某种init函数。
TextureRegion block1 = new TextureRegion(blockTextureRegion);
然后调用drawblocks函数。
case 0: spriteBatch.draw(block1, block.getPosition...
这样你只需要调用一次，而不是每次调用drawblocks。

您应该阅读此https://code.google.com/p/libgdx/wiki/TexturePacker
使用
batch.begin();
你的精灵渲染代码在这里
batch.end();
这将帮助您获得更高的fps
和纹理打包器确实提高了使用

下面是未编辑的代码，所以你可以得到一个想法，我使用WVC方法，继承人主要的渲染方法，plaz让我知道你是否想看到这里被调用的方法.. 我知道代码需要进行优化，所以如果有任何重大问题你会看到PLZ告诉我应该怎么做.. ty

答案 3 :(得分：0)
你必须明白每帧都会调用draw方法！因此，如果您多次分配40kb大小的纹理 - 每秒60次，这是对memmory带宽的大量使用！
那里也存在严重的内存泄漏，因为每个帧都会创建一个纹理区域而不会调用.dispose（）。
你要去的方法是在类init上创建纹理区域（例如在构造函数中）并将它们存储在私有的TextureRegion属性中，然后只使用它们。
在整个绘制方法中再没有新的关键字！这也适用于新的Color（1,1,1,1）..请改用priv属性并使用alocate一次或使用Color.WHITE ..
你使用的所有字符串都一样！没有+的字符串..也没有.toString（）e.t.c。
要偏执，你甚至不应该在draw中声明一个float / int属性..创建一个私有的aNd重用......
