Removing potion effects

I know this has been asked before but I still cant get it. How do I remove potion effects.

I used 4 different methods and now I'm stuck.

I'm currently using:

Code:java

p.addPotionEffect(new PotionEffect(PotionEffectType.ABSORPTION, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.BLINDNESS, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.CONFUSION, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.FAST_DIGGING, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.FIRE_RESISTANCE, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.HARM, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.HEAL, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.HEALTH_BOOST, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.HUNGER, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.INCREASE_DAMAGE, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.INVISIBILITY, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.JUMP, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.NIGHT_VISION, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.POISON, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.REGENERATION, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.SATURATION, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.SLOW_DIGGING, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.WATER_BREATHING, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.WEAKNESS, 0, 0),true);
                p.addPotionEffect(new PotionEffect(PotionEffectType.WITHER, 0, 0),true);

But that does not work.

 

To clear a certain potion effect you can use this:

Code:java

p.removePotionEffect(PotionEffectType.[whatever effect]);

to remove all a players potion effects you can use this:

Code:java

for (PotionEffect effect : p.getActivePotionEffects()){
            p.removePotionEffect(effect.getType());

 

Harmings I have tried those both and neither worked.

Can someone please help.

Forseth11 It should work, try what Harmings said.
