ActionButton的处理流程 天龙packet

什么破博客，，，崩溃了就要重写也不带自动保存

参考http://blog.csdn.net/butwang/archive/2011/02/15/6185631.aspx

function Packet_OnUpdateShow()

    szPacketName = "base";

    while i<j do
        local theAction,bLocked = PlayerPackage:EnumItem(szPacketName, i-1);
        PACKAGE_BUTTONS[k]:SetProperty("DragAcceptName", "P"..tostring(i));    
        --PushDebugMessage("packet index= " .. k.. " pos="..i);    
        if theAction:GetID() ~= 0 then
            PACKAGE_BUTTONS[k]:SetActionItem(theAction:GetID());
            itemnum = itemnum +1;
        else
            PACKAGE_BUTTONS[k]:SetActionItem(-1);
        end
        

通过PlayerPackage:EnumItem的第二个参数 i-1获得index 在map里查表 得到second为

  这部分的理解见之前luaplus的帖子

INT PlayerPackage::EnumItem(LuaPlus::LuaState* state)
{
    const static STRING s_strBaseName        = "base";        //基本物品  0-19
    const static STRING s_strMaterialName    = "material";    //材料物品 20-39
    const static STRING s_strQuestName        = "quest";        //任务物品 40-59

    LuaStack args(state);

    //检查参数
    if (!(args[2].IsString()))
    {
        KLThrow("LUA: PlayerPackage::EnumItem Wrong Param1");
    }
    if (!(args[3].IsInteger()))
    {
        KLThrow("LUA: PlayerPackage::EnumItem Wrong Param2");
    }

    STRING strPakageType = args[2].GetString();
    INT nIndex = args[3].GetInteger();
    
    //查询物品
    INT nOffIndex = -1;
    if(strPakageType == s_strBaseName)
    {
        nOffIndex = BASE_CONTAINER_OFFSET;
    }
    else if(strPakageType == s_strMaterialName)
    {
        nOffIndex = MAT_CONTAINER_OFFSET;
    }
    else if(strPakageType == s_strQuestName)
    {
        nOffIndex = TASK_CONTAINER_OFFSET;
    }

    if(nOffIndex >= 0)
    {
        tActionItem* pActionItem = CActionSystem::GetMe()->EnumAction(nIndex + nOffIndex, 
NAMETYPE_PACKAGEITEM);
        if(pActionItem)
        {
            LuaObject objReturn = state->BoxPointer(pActionItem);
            objReturn.SetMetaTable(*CActionItem::s_pMetaTable);
            objReturn.PushStack();

            if(((tObject_Item*)pActionItem->GetImpl())->IsLocked())
                state->PushInteger(1);
            else
                state->PushInteger(0);
            return 2;
        }
    }

    //非法ActionItem
    LuaObject objReturn = state->BoxPointer(&(CActionItem::s_InvalidAction));
    objReturn.SetMetaTable(*CActionItem::s_pMetaTable);
    objReturn.PushStack();


    state->PushInteger(0);
    return 2;
}

tActionItem* CActionSystem::EnumAction(INT nPosIndex, LPCTSTR szFilter)
{
    std::map< INT, CActionItem* >::iterator it;

    for(it=m_mapAllAction.begin(); it!=m_mapAllAction.end(); it++)
    {
        if(_stricmp(it->second->GetType_String(), szFilter) == 0) 
        {
            if(it->second->GetPosIndex() == nPosIndex)
            {
                return it->second;
            }
        }        
    }

    return NULL;
}

void LuaObject::SetMetaTable(const LuaObject& valueObj)
{
    luaplus_assert(m_state);
    lua_State* L = GetCState();  (void)L;
    lua_lock(L);
    luaT_setmetatable(m_state->m_state, &m_object, hvalue(&valueObj.m_object));
    lua_unlock(L);
}

    ActionButton::s_pMetaTable->RegisterObjectFunctor("SetActionItem"    , 
 &ActionButton::Lua_SetActionItem);
===================================
INT ActionButton::Lua_SetActionItem(LuaPlus::LuaState* pState)
{
    LuaStack args(pState);
    if (!(args[2].IsInteger())) return 0;
    
    INT idItem = (INT)args[2].GetInteger();

    Update(idItem);
    return 0;
}

VOID ActionButton::Update(INT idItem)
{
    //取得ActionItem
    tActionItem* pActionItem = g_pActionSys->GetAction(idItem);

    //断开和原来的Action的联系
    if(m_pActionItem && pActionItem != m_pActionItem)
    {
        m_pActionItem->RemoveRefrence(this);
    }

    if(NULL == pActionItem)
    {
        //如果逻辑项为空, 清空显示
        BeDestroyed();
        m_pWindow->setProperty("ShowTooltip","True");
        return;
    }
    //不显示默认tooltip
    m_pWindow->setProperty("ShowTooltip","False");
    //设置有效无效标记
    if(pActionItem->IsEnabled())
    {
        Bright();
    }
    else
    {
        Gloom();
    }

    //设置新的Action
    ((CEGUI::IFalagardActionButton*)(CEGUI::FalagardActionButton*)m_pWindow)->
 setLogicItemData((void*)(INT_PTR)pActionItem->GetID());

    m_pActionItem = pActionItem;
    LPCTSTR DragName = ((CEGUI::FalagardActionButton*)m_pWindow)->getDragAcceptName();

    if(DragName[0] == 'M' || DragName[0] == 'F')
    {
        pActionItem->AddReference(this,TRUE);
    }
    else
    {
        pActionItem->AddReference(this,FALSE);
    }

    const STRING strIconName = 
        CUISystem::GetMe()->GetIconManager()->GetIconFullName(m_pActionItem->GetIconName());

    m_pWindow->show();
    m_pWindow->setProperty("Empty", "False");
    if(!strIconName.empty())
    {
        m_pWindow->setProperty("NormalImage", strIconName);
    }
}

tActionItem* CActionSystem::GetAction(INT id)
{
    std::map< INT, CActionItem* >::iterator it;

    it = m_mapAllAction.find(id);
    if( it != m_mapAllAction.end() )
        return it->second;

    return NULL;
}

总体流程应该是这样的：

  一开始初始化的时候，当前背包的物品 遍历一遍 每个执行 local theAction,bLocked = PlayerPackage:EnumItem(szPacketName, i-1)

m_mapAllAction这里面装了所有的action当前人物的包里的action 的位置posindex也被存在里面了

it->second->GetPosIndex() == nPosIndex

获得到cActionItem=theAction 的到id绑到button上

 rbclick的时候 调用 相应item的 doaction向服务器端发包
