Be more detailed with the first question.
To fix the time before the bomb explodes, look at MapleMap.java (one of the spawn methods in there has a check for a mob id for a bomb)
@Override public void sendPackets(MapleClient c) {
c.getSession().write(MaplePacketCreator.spawnMonster(monster, true));
if (monster.getId() == 9300166 || monster.getId() == 8810026) {
TimerManager.getInstance().schedule(new Runnable() {
@Override
public void run() {
killMonster(monster, (MapleCharacter) getAllPlayer().get(0), false, false, 4);
}
}, 300 + Randomizer.getInstance().nextInt(500));
}
What do i change? 0.0
