Problem in setTimer with the C++ API for modules

[ryden]

When calling setTimer from a module, if you specify parameters to be sent to the callback and this parameter is a custom userdata it won't work.

Works fine when you send plain data like, for example, a number. But if you push a userdata with this code this is what happens:

static int test(lua_State* L) 
{ 
  pModuleManager->Printf("Timer called the callback\n"); 
  return 0; 
} 
  
int myFunction(lua_State* L) 
{  
  lua_getglobal(L, "setTimer"); 
  lua_pushcfunction(L, test); 
  lua_pushnumber(L, 1000); 
  lua_pushnumber(L, 3); 
  lua_newuserdata(L, sizeof(char)); /* Here we push the userdata */ 
  lua_call(L, 4, 1); 
  lua_pop(L, 1); 
}

[07:33:16] ERROR: attempt to call a string value

Now the same, but pushing a number:

static int test(lua_State* L) 
{ 
  pModuleManager->Printf("Timer called the callback\n"); 
  return 0; 
} 
  
int myFunction(lua_State* L) 
{  
  lua_getglobal(L, "setTimer"); 
  lua_pushcfunction(L, test); 
  lua_pushnumber(L, 1000); 
  lua_pushnumber(L, 3); 
  lua_pushnumber(L, 16); /* Now instead of the userdata, we push a number */ 
  lua_call(L, 4, 1); 
  lua_pop(L, 1); 
}
