How do I use player.addPotionEffect? It takes PotionEffect as a parameter but I can't figure it out. Here is some code:

public void poisonPlayer(EntityPlayer player){
        player.addChatMessage(new ChatComponentText(EnumChatFormatting.RED + "You have been stung."));
        
        player.addPotionEffect();
    }

player.addPotionEffect(new PotionEffect(id, 9600, 0));

 

Id is the effect id, I looked it up on minecraft wiki.

9600 is duration, in ticks. 9600 = 20 * 8 * 60 = 8 min

0 is amplitude, means level1. If you want level n, use (n-1).

Here is an example for you:

 

player.addPotionEffect(new PotionEffect(Potion.fireResistance.id, 10, 0))

Ok, thanks.
