Add potioneffect that the player can't see?

Hey guys.
There are some plugins that give players PotionEffects that affect the player as usual.
But when the player opens his inventory he can't see the effect beside the inventory.

How is that possible?

 

which effect are those? i know that you can do slowness and speed via Player.setWalkSpeed(speed); (not sure if said it right)

 

MinecraftShamrock
Some things can be also done by other methods, some effects are handled client-side.

Strength and weakness can be done through EntitiyDamagedByEntityEvent

 

Strength + Weakness : EntityDamageByEntityEvent
Jump : PlayerMoveEvent>velocity
Speed + Slowness : player.setWalkSpeeed(int);
Mining haste : PlayerInteractEvent>Left click block> ...
etc...

 

Asticoli_express So if I want to cancel a jump without let a player bug around i could set his y velocity to 0?

Or would that only port him back? Because i want him to stay unlike cancel a move event that would port him back

 

But anyway why don't you want to directly use potions? why seeing it in the inventory is such a problem?

Use this and he will almost not be able to jump :

Code:java

@EventHandler
    public void onMove(PlayerMoveEvent e){
        Player p = e.getPlayer();
        if(e.getFrom().getY()<e.getTo().getY()){
            p.setVelocity(p.getVelocity().add(new Vector(0,-10,0)));
        }
    }

Asticoli_express And will the player be ported back? (Same as cancelling the event) or won't he even move on the client side?

 

MinecraftShamrock
If you do player.setPassenger(player); he won't move but one side effect is that he is sitting in midair

 

xTrollxDudex so he's sitting on himself? (Lol)
Could he move at all? Or just not jump?

 

MinecraftShamrock
Nope. Not at all. Probably can look around, but I haven't tested that yet. You can always make him stop sitting using

PHP:

player.eject()

 

xTrollxDudex cool thank you very much! Finally a nice way of prevent player moving.

 

there is an easyer way

p.getPlayerMovmentType().equals(Player.GetMoveType().cancel); =)
good luck ^^

 

No.

 

MinecraftShamrock if you want that player wont be able to jump (client side (?)) , use p.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, set here level to -1 and time to the time you want)) << havent checked it in eclipse, but thatshow i make the player wont be able to jump

 

But he doesn't want the potion effect to show when the player opens his inventory.

 

Asticoli_express yea, im just telling him that its another way... (if he want it client side..)
