C++ What function in tfs 0.4?

[Adix910]

Hi, yesterday i found the script:

lua_register(m_luaState, "selfAttackCreature", NpcScriptInterface::luaActionAttackCreature);

int32_t NpcScriptInterface::luaActionAttackCreature(lua_State* L){
int id=(int)lua_tonumber(L, -1);
Npc* npc = getNpc(popNumber(L));
if(npc)
npc->doAttack(id);
return 0;
}

The code is to create functions for attacking creatures by npc
and so there was an error in the compilation

[2648] npc.cpp `getNpc' was not declared in this scope

How to fix it?

Where did you take that function from?

NPC's can't attack other creatures in TFS 0.4. Its reserved only for monsters and players.

The function would look this:

int32_t NpcScriptInterface::luaActionAttackCreature(lua_State* L) {
    //selfAttackCreature(cid)
    ScriptEnviroment* env = getEnv();
    Npc* npc = env->getNpc();
    if(!npc)
        return 0;

    Creature* creature = env->getCreatureByUID(popNumber(L));
    if(creature)
        creature->doAttack(id);

    return 0;
}

The problem is, there is no doAttack(id) function in TFS 0.4. So the code won't work, but I gave you an example how to do such a function.

@slawkens
Thank you,
So you'll be able to help me do this?
doAttack

@Adix910
You are going wrong way about it;

post where did you find that function in your first post. Ideally it should be part of sources, which will contain everything you need to implement it into your engine. Since its a new function it may not be just copy-paste.

 

[Adix910]

I found this on a sticker.
Really, npc can not attack players in tfs 0.3.6-0.4?

 

[Lyky]

you can make a workaround inside npc as such; (this is just example, but you can make more advanced, randomized attacks, literally to behave like a monster.)

local guardCondition = Condition(CONDITION_FIRE, CONDITIONID_COMBAT)
guardCondition:setParameter(CONDITION_PARAM_DELAYED, 10)
guardCondition:addDamage(10, 3000, -10)

player:getPosition():sendMagicEffect(CONST_ME_HITBYFIRE)
player:addCondition(guardCondition)
npc:getPosition():sendDistanceEffect(player:getPosition(), CONST_ANI_FIRE)

inside npc_name.xml you can also specify if you want this npc to be attackable by players.

or further it up within creaturescripts and events to transform;

There is doAttacking function in player class.

 

[Adix910]

Thanks
But this unfortunately will not work, because npc creates summons that are supposed to attack the player.

 

[Lyky]

then its even easier... just spawn monsters... no need for npc to do any kind of attacks.

local creatures = { 'Monster1', 'Monster2' }

for i = 1, #creatures do
Game.createMonster(creatures, Npc():getPosition())
end

What if I would like to do it in this example?

local function doSummonPokemon(npc)
    local this = npc
    if not isCreature(this) then return true end
    if #getCreatureSummons(this) >= 1 or focus == 0 then return true end
    local it = pokemons[battle_turn]
    doSummonMonster(this, it.name)
    local summon = getCreatureSummons(this)[1]
    local balleffect = pokeballs["normal"].effect
        if it.ball and pokeballs[it.ball] then
            balleffect = pokeballs[it.ball].effect
        end
    doSendMagicEffect(getThingPos(summon), balleffect)
    setPlayerStorageValue(summon, 10000, balleffect)
    setPlayerStorageValue(summon, 10001, gobackmsgs[math.random(#gobackmsgs)].back:gsub("doka", it.nick ~= "" and it.nick or it.name))
    setPlayerStorageValue(summon, 1007, it.nick ~= "" and it.nick or it.name)
    doSetMonsterGym(summon, focus)
    local name = it.nick ~= "" and it.nick or getCreatureName(this).."s "..it.name
    setWildPokemonLevel(summon, it.level, getPokemonStatus(it.name, (it.extralevel + it.level)), name, 1.5)
    doCreatureSay(this, gobackmsgs[math.random(#gobackmsgs)].go:gsub("doka", getPlayerStorageValue(summon, 1007)), 1)
    fighting = true
    battle_turn = battle_turn + 1
end

its pretty much same thing as orc king was doing

but i'd recommend doing it through events and creaturescripts, to script the encounters. NPC would only activate certain event so you get turns once other monster is defeated

 

[Adix910]

Thanks, but the orcs are created as summons

 

[Lyky]

you can change monsters that are being created inside the npc script or event
