S60游戏移植到S40上遇到的问题

[zsq010]

其中有一个类有90多k，里面包括游戏所有的逻辑，有许多静态的成员变量和方法，单加载这一个类40的215040bit的内存都不够用，各位大虾有啥好办法嘛？请赐教，谢谢！！

[hszr99]

可以把类合并，没创建一个类大约要用0.2K左右的空间。
S40的我们公司是<59K的。图片也不能太压缩，否则对游戏的
画面有影响.

[ransion]

6k的图,lz你还是留在S60里用吧,S40由于性能的原因是要作出适当的取舍

看上去释放资源是一个好的方法,但是实际应用中频繁的释放和在创建并不能从本质上解决堆不够的问题

因为java毕竟它的释放空间不可能很彻底,而且我们也不能控制GC的行为

ps:
图的压缩可以试试这个工具:xat.com Image Optimizer

[homesos]

既然是运行于s40上，那图片进行压缩后，看上去不会有什么明显滴差距滴

[cnesky]

该说的都说了，再说就只有把代码贴出来，大家帮你压缩类了

[cnesky]

实在压缩不了的话 还有一个方法， 就是做这个游戏的DEMO版，去掉一些功能了 ：）

[homesos]

呵呵
听起来这个类是蛮强滴

[JavaAndJava]

把这个类拆开了，分成几个类，一般3000行代码运行起来没有什么问题，但是不要在一个文件中，分开写，分开加载就没什么问题，具体怎么拆，那就只有看代码了~

[gameover1234]

楼上的家伙谁能分得清楚：
1，jar的大小
2，运行时内存大小

的区别？

nokia 40系列

1,jar的大小最大不能超过65k,否则不能运行。
2,运行时内存大小是220k

jar里面的图片是压缩的，一般来说jar里面的图片在程序运行时，经过手机解压装载到内存里是原先的10倍（大概估计）。

有不同意见的请举手。

成员变量就这么一大堆，加载时还没有执行构造函数就占用了60多k的内存，各位大虾，有没有办法优化啊？

[homesos]

如果想要代码清晰明了，自然会多费些代码，效率可能也会降低。
如果想要追求效率，代码可能就要变的难懂一些。

如果你实在想要减少内存，不妨将
像 private static final int PORTWIDTH = 128; 这样的，去掉，直接在代码里使用，也许会好些。

在使用的地方，写注释标明。

[zsq010]

谢谢的各位指点，昨天程序优化那篇文章我找到了，通读一遍，获益匪浅！！

图片已经压缩过了，共占用18k左右，已经到最小极限了，再压缩就如随风兄所说，降低游戏画面的质量了。

我单独加载了一下逻辑类，测试结果如下：
Allocated world, heap left 196176
LoadTexts Begin
numtexts = 59
Allocated world, heap left 1956

源文件有90多k，有3000多行，这个类是逻辑类，所有的控制都在这里，单把它加载进来后用掉190多k的内存，别的就啥了做不了了。
这类老外写的，竟然没有一句注释，头都大了，~_~

各位兄弟，如何给这个类瘦身一下啊，请多提宝贵意见，谢谢了先

[cnesky]

楼主会使用7za.zip这个开源工具吗??

在sourceforge.net上去下载一个,然后用ant调用它预编译代码，这些变量80%就会自动处理掉了

[zjstu]

static final int 之类的东西混淆的时候就会去掉的。
我估计是你的代码类太多了吧，我写的一个S40单文件4000行都没你这么大,58K的样子，图片还用了18K

[xueyong1203]

能用局部变量的尽量使用局部变量~~~

[xueyong1203]

static 和 final 可以小幅提高运行速度
