[LUA + C++] Custom Fly Taxi without Gossip

Hello,

i remove the gossip requirement for custom taxi's

UnitMethods.h

Code:

    int GetVehicleBase(lua_State*, Unit*);
    int HasEmptySeat(lua_State*, Unit*);
    int StartTaxi(lua_State*, Unit*);
  + int StartCustomTaxi(lua_State*, Unit*);
    int SetPlayerLock(lua_State*, Unit*);
    int GetNearestPlayer(lua_State*, Unit*);
    int GetNearestGameObject(lua_State*, Unit*);

UnitMethods.cpp

Code:

int LuaUnit::StartTaxi(lua_State* L, Unit* unit)
{
    TO_PLAYER();

    uint32 pathId = luaL_checkunsigned(L, 1);

    LuaTaxiMgr::StartTaxi(player, pathId);
    return 0;
}

+ int LuaUnit::StartCustomTaxi(lua_State* L, Unit* unit)
+ {
+     TO_PLAYER();
+ 
+     uint32 pathId = luaL_checkunsigned(L, 1);
+ 
+     LuaTaxiMgr::StartCustomTaxi(player, pathId);
+     return 0;
+ }

int LuaUnit::SetPlayerLock(lua_State* L, Unit* unit)
{
    TO_PLAYER();

    bool apply = luaL_optbool(L, 1, true);

    if (apply)
    {
        player->SetFlag(UNIT_FIELD_FLAGS, UNIT_FLAG_PACIFIED | UNIT_FLAG_SILENCED);
        player->SetClientControl(player, 0);
    }
    else
    {
        player->RemoveFlag(UNIT_FIELD_FLAGS, UNIT_FLAG_PACIFIED | UNIT_FLAG_SILENCED);

Thanks for the share mate

Hmm .. I dont get it.
What did you do exactly?
You can already have flight points and flying without gossip.. on eluna

Nirelz · Aug 17, 2013

Tested it and it dosnt set you on a "flying mount"... it simply just teleports you towards final destination...
