[Lava Titan]

Hi

Can anyone tell me in what source file is the code that doesn't let players push from pz to nopz ?

onMoveCreature(creature, fromPosition, toPosition)

I found this but I have no idea how to use it

on fine game.cpp, here is the code it's C++:

void Game::playerMoveCreature(Player* player, Creature* movingCreature, const Position& movingCreatureOrigPos, Tile* toTile)
{
    if (!player->canDoAction()) {
        uint32_t delay = player->getNextActionTime();
        SchedulerTask* task = createSchedulerTask(delay, std::bind(&Game::playerMoveCreatureByID,
            this, player->getID(), movingCreature->getID(), movingCreatureOrigPos, toTile->getPosition()));
        player->setNextActionTask(task);
        return;
    }

    player->setNextActionTask(nullptr);

    if (!Position::areInRange<1, 1, 0>(movingCreatureOrigPos, player->getPosition())) {
        //need to walk to the creature first before moving it
        std::forward_list<Direction> listDir;
        if (player->getPathTo(movingCreatureOrigPos, listDir, 0, 1, true, true)) {
            g_dispatcher.addTask(createTask(std::bind(&Game::playerAutoWalk,
                                            this, player->getID(), listDir)));
            SchedulerTask* task = createSchedulerTask(1500, std::bind(&Game::playerMoveCreatureByID, this,
                player->getID(), movingCreature->getID(), movingCreatureOrigPos, toTile->getPosition()));
            player->setNextWalkActionTask(task);
        } else {
            player->sendCancelMessage(RETURNVALUE_THEREISNOWAY);
        }
        return;
    }

    if ((!movingCreature->isPushable() && !player->hasFlag(PlayerFlag_CanPushAllCreatures)) ||
            (movingCreature->isInGhostMode() && !player->isAccessPlayer())) {
        player->sendCancelMessage(RETURNVALUE_NOTMOVEABLE);
        return;
    }

    //check throw distance
    const Position& movingCreaturePos = movingCreature->getPosition();
    const Position& toPos = toTile->getPosition();
    if ((Position::getDistanceX(movingCreaturePos, toPos) > movingCreature->getThrowRange()) || (Position::getDistanceY(movingCreaturePos, toPos) > movingCreature->getThrowRange()) || (Position::getDistanceZ(movingCreaturePos, toPos) * 4 > movingCreature->getThrowRange())) {
        player->sendCancelMessage(RETURNVALUE_DESTINATIONOUTOFREACH);
        return;
    }

    if (player != movingCreature) {
        if (toTile->hasProperty(CONST_PROP_BLOCKPATH)) {
            player->sendCancelMessage(RETURNVALUE_NOTENOUGHROOM);
            return;
        } else if ((movingCreature->getZone() == ZONE_PROTECTION && !toTile->hasFlag(TILESTATE_PROTECTIONZONE)) || (movingCreature->getZone() == ZONE_NOPVP && !toTile->hasFlag(TILESTATE_NOPVPZONE))) {
            player->sendCancelMessage(RETURNVALUE_NOTPOSSIBLE);
            return;
        } else {
            if (CreatureVector* tileCreatures = toTile->getCreatures()) {
                for (Creature* tileCreature : *tileCreatures) {
                    if (!tileCreature->isInGhostMode()) {
                        player->sendCancelMessage(RETURNVALUE_NOTENOUGHROOM);
                        return;
                    }
                }
            }

            Npc* movingNpc = movingCreature->getNpc();
            if (movingNpc && !Spawns::isInZone(movingNpc->getMasterPos(), movingNpc->getMasterRadius(), toPos)) {
                player->sendCancelMessage(RETURNVALUE_NOTENOUGHROOM);
                return;
            }
        }
    }

at this line:

...
else if ((movingCreature->getZone() == ZONE_PROTECTION && !toTile->hasFlag(TILESTATE_PROTECTIONZONE)) || (movingCreature->getZone() == ZONE_NOPVP && !toTile->hasFlag(TILESTATE_NOPVPZONE))) {

Thanks

Btw, any idea where can I change the max distance to show item description?

at this moment you can only see description if ur close to the item, i wanna make it 5 sqm max item description distance

somewhere at this function in game.cpp

void Game::playerLookAt(uint32_t playerId, const Position& pos, uint8_t stackPos)
{
    Player* player = getPlayerByID(playerId);
    if (!player) {
        return;
    }

    Thing* thing = internalGetThing(player, pos, stackPos, 0, STACKPOS_LOOK);
    if (!thing) {
        player->sendCancelMessage(RETURNVALUE_NOTPOSSIBLE);
        return;
    }

    Position thingPos = thing->getPosition();
    if (!player->canSee(thingPos)) {
        player->sendCancelMessage(RETURNVALUE_NOTPOSSIBLE);
        return;
    }

    Position playerPos = player->getPosition();

    int32_t lookDistance;
    if (thing != player) {
        lookDistance = std::max<int32_t>(Position::getDistanceX(playerPos, thingPos), Position::getDistanceY(playerPos, thingPos));
        if (playerPos.z != thingPos.z) {
            lookDistance += 15;
        }
    } else {
        lookDistance = -1;
    }

    g_events->eventPlayerOnLook(player, pos, thing, stackPos, lookDistance);
}

you have to change the logic to fit your needs
