00003不思议迷宫.0010.1.1.2：csb解析显示
Mac上调试app有点蛋疼，每次运行都要打包来打包去，慢。我对Xcode不熟，不会修改工程文件让它不打包。我决定，换到Windows下，使用VS。
上次用3.3 rc0未能解析出csb，已发现确实是操作错误（还是环境变量冲突）。这次就用3.3 rc0来。
执行创建：cocos new BSYMG -p com.your_company.BSYMG -l lua -d C:\BSYMG
添加读取png补丁，打开CCImage.cpp：
添加全局函数：
//
// tiewen patched
//
staticconstchar*xorEncryptKey="// Dump Ref object memory leaks if(__refAllocationList.empty()) { log([memory] All Ref objects successfullycleaned up (no leaks detected).); } else { log([memory] WARNING: %d Ref objectsstill active in memory., (int)__refAllocationList.size()); for (const auto&ref : __refAllocationList) { CC_ASSERT(ref); const char* type =typeid(*ref).name(); log([memory] LEAK: Ref object %s still active with referencecount %d., (type ? type : ), ref->getReferenceCount()); }}";
staticvoidxorEncrypt(unsignedchar*v,int length)
{
autoxorEncryptKeyLength = strlen(xorEncryptKey);
for(inti = 0; i < length; ++i)
{
v[i]^= (unsignedchar)xorEncryptKey[i% xorEncryptKeyLength];
}
}
staticintxorEncryptingLength(unsignedchar*v,int length)
{
if(length <= 200)return length;
return200;
}
staticboolisEncryptedPng(unsignedchar*v,int length)
{
return(v[0] != 0x89) || (v[1] !='P') ||(v[2] !='N') || (v[3] !='G');
}
staticunsignedchar*ToPlainPng(unsignedchar*v,int length)
{
if(isEncryptedPng(v, length)) xorEncrypt(v, xorEncryptingLength(v, length));
returnv;
}
staticunsignedchar*ToEncodedPng(unsignedchar*v,int length)
{
xorEncrypt(v, xorEncryptingLength(v, length));
returnv;
}
修Image::isPng：
bool Image::isPng(constunsignedchar* data, ssize_t dataLen)
{
if(dataLen <= 8)
{
returnfalse;
}
staticconstunsignedcharPNG_SIGNATURE[] = {0x89, 0x50, 0x4e, 0x47, 0x0d, 0x0a, 0x1a,0x0a};
//tiewenpatched begin
staticunsignedchardecryptedData[8];
memcpy(decryptedData, data, 8);
if(isEncryptedPng(decryptedData,8))//isEncrypted
{
xorEncrypt(decryptedData, 8);
returnmemcmp(PNG_SIGNATURE, decryptedData,sizeof(PNG_SIGNATURE))== 0;
}
//tiewenpatched end
returnmemcmp(PNG_SIGNATURE, data,sizeof(PNG_SIGNATURE))== 0;
}
修改Image::initWithPngData：
bool Image::initWithPngData(constunsignedchar* data, ssize_t dataLen)
{
data =ToPlainPng((unsignedchar*)data, dataLen);// tiewen patched
……
}
添加读取luac的补丁，打开Cocos2dxLuaLoader.cpp，修改：
intcocos2dx_lua_loader(lua_State *L)
{
……
if(chunk)
{
//tiewen patched begin
int offset = 0;
if (chunk[offset] == 0xef &&chunk[offset + 1] == 0xbb && chunk[offset + 2] == 0xbf) offset += 3;
if (chunk[offset] == 0x11 &&chunk[offset + 1] == 0x12 && chunk[offset + 2] == 0x13) offset += 3;
LuaStack* stack =LuaEngine::getInstance()->getLuaStack();
//stack->luaLoadBuffer(L,(char*)chunk, (int)chunkSize, chunkName.c_str());
stack->luaLoadBuffer(L,(char*)chunk + offset, (int)chunkSize - offset,chunkName.c_str());
//tiewen patched end
……
}
……
}
同时支持普通的lua文件、解密后的luac文件和修改后拥有BOM头的解密luac文件。
用VS打开frameworks\runtime-src\proj.win32下的工程文件，F5，耐心等待后，默认的农场结界就出来了。
下面要解决《不思议迷宫》的csb显示问题。当然，显示不是问题，问题是显示得要和游戏中一样。为此，希望能够直接使用游戏的luac文件。但游戏的luac文件中可能包含了额外的游戏逻辑，这部分代码在我们的环境下无法运行，需要剔除。
首先要修改掉框架默认的分辨率。
打开src/main.lua，修改：
if nil == glview then
glview =cc.GLViewImpl:createWithRect("HelloLua", cc.rect(0,0,540,960))
director:setOpenGLView(glview)
end
glview:setDesignResolutionSize(540,960, cc.ResolutionPolicy.NO_BORDER)
修改为和iPhone 5等比例的分辨率。
然后去除框架默认的界面，修改为我们自己想要显示的：
local sceneGame = cc.Scene:create()
local node =cc.CSLoader:createNode("layout/dungeon/DungeonMain.csb");
sceneGame:addChild(node)
能显示，但和cocos2dx-cpp中的一样，位置不对且不完整，需要调整。/src/game/ui/form/dungeon/UIDungeonMain.luac中的无疑是最正确的，但我们没办法直接使用，里面有很多不知所谓的代码。慢慢来。为了方便以后切换各个场景，我们也把相关的代码包装到类中。由于我们只捣鼓UI，就不像《不思议迷宫》那样地分那么多目录层级了，全部放到my目录下。建立/src/my/UIDungeonMain.luac，打开编辑，内容如下：
require("game/ui/base/util/Node");
require("game/ui/base/TextStyleM");
--每个关卡由6行5列的格子组成
GRID_ROW_NUM= 6;
GRID_COL_NUM= 5;
TOTAL_GRID_NUM= GRID_ROW_NUM * GRID_COL_NUM;
--格子宽、高
GRID_WIDTH = 128;
GRID_HEIGHT= 118;
--格子的纵向偏移量
GRID_OFFSET_Y= 80;
--格子刷怪的延迟
GRID_REFRESH_MONSTER_DELAY = 0.7
--UIDungeonMain继承自Layer
UIDungeonMain= class("UIDungeonMain", function()
return cc.Layer:create();
end);
functionUIDungeonMain.create(levelData, layer)
return UIDungeonMain.new(levelData, layer);

end
-- 计算最右边的点的坐标
local pos =skillEnergyBarNode:getParent():convertToNodeSpace(cc.p(w, 0));
-- 能量圈始终紧靠右边
skillEnergyBarNode:setPositionX(pos.x);
end
代码中用到了原版中的一些内容，直接将对应文件拷贝到相应目录即可。其中有一些错误需要自己修正。游戏使用了某种技术，可以自动在lua中将类型向下转换，或者是弄了个超大集合类，反正我是不懂，比如：
self.attackLabel =findChildByName(self.node, "CT2/atk_val");
setStyle(self.attackLabel);
local function setStyle(textNode)
……
textNode:setFontSize(28);
……
end
self.attackLabel是cc.Node，而在setStyle函数中直接调用了某个派生类才有的textNode:setFontSize(28);请问是如何做到的？
另外，self.attackLabel的最终类型是ccui.Text，它并没有一个叫做:setTTFConfig(fontName,fontSize, olColor, olSize)的函数（有个类有这个函数，但不是4个参数），因此TextStyleM. setTextStyle作了一点修正：
-- targetNode:setTTFConfig(fontName,fontSize * smoothScale, olColor, olSize);
targetNode:setFontName(fontName);
targetNode:setFontSize(fontSize *smoothScale);
终于正常显示了：
