addEvent error

[whiteblXK]

Hello, for some time I have a problem with function addEvent, when I want to use it in the following way:

addEvent(doTeleportThing, 500, cid, pos)

I have this error:

callback parameter should be a function

But when I use in this way:

addEvent(function()
      if isPlayer(cid) then
               doTeleportThing(cid, pos)
       end
end, 500, cid)

I don't have any error.

How to use correctly first way in this function?

If the error is on the side of the source I put functions addEvent:

int LuaScriptInterface::luaAddEvent(lua_State *L)
{
    //addEvent(callback, delay, parameter)
    ScriptEnviroment* env = getScriptEnv();

    LuaScriptInterface* script_interface = env->getScriptInterface();
    if(!script_interface){
        reportError(__FUNCTION__, "No valid script interface!");
        lua_pushnumber(L, LUA_ERROR);
        return 1;
    }

    if(lua_isfunction(L, -3) == 0){
        reportError(__FUNCTION__, "callback parameter should be a function.");
        lua_pushnumber(L, LUA_ERROR);
        return 1;
    }

    LuaTimerEventDesc eventDesc;
    eventDesc.parameter = luaL_ref(L, LUA_REGISTRYINDEX);
    uint32_t delay = popNumber(L);
    if(delay < 100){
        delay = 100;
    }
    eventDesc.function = luaL_ref(L, LUA_REGISTRYINDEX);

    eventDesc.scriptId = env->getScriptId();

    script_interface->m_lastEventTimerId++;
    script_interface->m_timerEvents[script_interface->m_lastEventTimerId] = eventDesc;

    g_game.addEvent(makeTask(delay, boost::bind(&LuaScriptInterface::executeTimerEvent, script_interface, script_interface->m_lastEventTimerId)));
    lua_pushnumber(L, script_interface->m_lastEventTimerId);
    return 1;
}

You forgot to add which server you use.

I use Devland 0.97B SQL

addEvent(function(cid)

 

[whiteblXK]

Printer, I do not know what you wanted to tell me.

Replace your code with this:

addEvent(function(cid, position)
    if not isPlayer(cid) then
        return false
    end
   
    doTeleportThing(cid, position)
end, 500, cid, pos)

My code works fine:

addEvent(function()
      if isPlayer(cid) then
               doTeleportThing(cid, pos)
       end
end, 500, cid)

This not working and I don't know why :/

addEvent(doTeleportThing, 500, cid, pos)

Use the first one though, much better. Else the server will complain and send you error notices if the player should die within the launch.

addEvent(doTeleportThing, 500, cid, pos)

This will either cause server crash or error. Due to it's not checking if the player is there.

 

[whiteblXK]

Hmm, when I use this addEvent:

addEvent(test,2000,cid)

and function test:

function test(cid)  
    if isPlayer(cid) == 1 then   
        doPlayerSay(cid, 'Test', TALKTYPE_ORANGE_1) 
    end      
end

i have this error again :/ Why?

 

[Printer]

Show me the error

 

[whiteblXK]

luaAddEvent(). callback parameter should be a function.

 

[Printer]

The error does not make any sense, try change function name and also don't use == 1 enough with isPlayer(cid) then

 

[whiteblXK]

I change

isPlayer(cid) == 1

to

isPlayer(cid)

and I don't have error, and script works. lol

In this:

addEvent(doSendMagicEffect, 5000, getPlayerPosition(cid), CONST_ME_SOUND_YELLOW)

I have again this error, can you tell me how to fixt it?

luaAddEvent(). callback parameter should be a function.
