[1.11] Adding a potion effect to a player

[MSpace-Dev]

Hey everyone,

 

So, all I need to do is add a potion effect to a player. I've managed to get the player object already, so I have access to that. I'm just not quite sure how to use addPotionEffect correctly. I've been trying many variations to get it to atleast accept it. But yeah, here is a very small part of my code. I've seen around the internet that they go Potion.getPotionByID(), or was it PotionEffect.getPotionByID()? Either way, it doesn't seem to be supported here.

 

for (EntityPlayer player : list) {
            player.addPotionEffect(); // Add effect here
}

 

Thanks!

Look for other uses of the method.

I was going to do that, but I was going out for the day, and decided to post a question instead. When I get home I'll just do it, was hoping I could just jump right into it when I get home later today

player.addPotionEffect(new PotionEffect(Potion.getPotionById(19), 100, 0));

Here is the example. 19 is id of potion which is equals to Poison, 100 is duration of potion 20ticks per second, so 100 is equals to 5 seconds. and 0 is a level of potion. (zero-based) so if you type 2 for level, it equals level 3 potion effect. You can get ids from net.minecraft.potion.Potion.java.

Bad modder, no cookie. Do not use hard coded IDs.

@xwerswoodx As I said, I went to go look through the code, already figured that out, but thanks =p

 

@Draco18s What would you use instead of hardcoded IDs? The only code I found that used to give the potion effect used the IDs. Care to share an example that doesn't use them?

You know how Blocks.DIRT is a thing so you don't need to do Block.getBlockByID(1)?

Potion effects work the same way.

Ah, simple enough. Thanks for the info!

I know MobEffects initialization. But he asked about 

"I've seen around the internet that they go Potion.getPotionByID(), or was it PotionEffect.getPotionByID()? Either way, it doesn't seem to be supported here."

 

So I answered him same way. Sorry bro but knowing "MobEffects" init doesn't make you good or bad modder. Anyway here is the code with "MobEffects" for "GOOD" mooders...

 

player.addPotionEffect(new PotionEffect(MobEffects.POISON, 100, 0));

The correct way to answer was to tell him to not use that method and to instead use MobEffects.

If this topic was not solved yet:

MinecraftServer server = FMLCommonHandler.instance().getMinecraftServerInstance();
List<EntityPlayer> list = Lists.newArrayList(server.getPlayerList().getPlayers());

for (EntityPlayer playerIn : list) //for each player in the player list
{
  playerIn.addPotionEffect(new PotionEffect(MobEffects /* don't get effect from ID, IDs can change */... effect, int... duration, int... amplifier, boolean... particles, boolean... isAmbient));
}

Hope I helped
