XP

Hey Guys,
I already asked someone about this and they were sort of unsure and I wanted to save them the time of helping me if they weren't positive. Iam making a plugin and it will kind of have a shop sort of thing but via XP. So when you run a command you would lose XP. I was wondering if you could do anything to do this. I tried adding negative XP but that doesn't work. I was suggested a algorithm but I would like to be positive before I make one because the levels seem to be done in no sort of order at all. Thanks,
~JHA

 

they are done as percentage values. so 0 would be no xp, 0.99 would be 1 xp to lvl up.
1 would be leveled up. Then it reverts back to 0. How MC deals with gaining less XP at higher level is probably something like xp / level or soemthing like that

 

When I give someone XP it is done by Orbs.

Code:

e.getEntity().getKiller().giveExp(17);

I don't know of any other methods. And I also am trying to take away XP from the player when they run a command. Thanks anyway.

 

so do this:
e.getEntity().getKiller().setExp(e.getEntity().getKiller().getExp() - ([REMOVING XP COMMAND INT] / 100));
That is a calculation. Gets the xp

 

Oh, your trying to get orbs from a EntityDeathEvent.

Why not just do player.giveExp(Integer); or player.giveExpLevel(Integer)?

 

william9518 danthonywalker no he is trying to remove absolute xp points (so no floats, just integers. Also, from the total amount, not the xpbar)

 

This:

I found out how this is done and thought I would share since some of you were un-sure.
First you need both of these.

Code:

Player player = (Player)sender;
int xp = player.getLevel();

Code:

    if ((commandLabel.equalsIgnoreCase("jumphigh"))){//Is command typed is equal to but ignore caps jumphigh
        if(((player.hasPermission("test.jumphigh")) || (player.isOp()))) {//And player has permission test.jumphigh or you are op
            if(!(xp<10)){//If your xp level is not less than the price of the item.
                player.setLevel(xp-10);//Then subtract the price for command
                player.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 1200, 10));//Give them potion
            }else{
                player.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 20, 0));//If they don't qualify then give them this potion effect
                player.sendMessage("You cannot afford this.");//And this message
            }
        }
    }
