I am trying to make a food item that when eaten gives the user multiple effects like the golden apple from vanilla minecraft.

 

        this.setPotionEffect(Potion.regeneration.id, 50, 5, 100);

        this.setPotionEffect(Potion.fireResistance.id, 500, 1, 100);

 

Is the code I am using but the user only gets the Fire resistance effect and not regeneration. Please help!

Do it the same way Golden "Notch" Apples do it.

The vanilla golden apple uses .addPotionEffect

but when I try to use it it says it doesn't exist

It means it's probably a private method. You could try recreating the original Golden Apple file structure and using that.

The addPotionEffect methord is part of EntityLivingBase and is public.

but I have no idea how I would use it

Just recreate the file structure, or make an instance of the file that add the method.

You can give a player a potion effect using this method:

player.addPotionEffect(new PotionEffect(id, ticks, amplifier));

 

I use this often.

I get an Error:

java: cannot find symbol

  symbol:  variable player

Don't just copy & paste. Try to understand what's happening.

 

I didn't copy & paste. just when I typed it in and added my variables it didn't work

 

        player.addPotionEffect(new PotionEffect(Potion.fireResistance.id, 500, 1));

Again, I have worded it wrong. I never meant new World instance specifically, I meant new instance of the file itself, not the World file. Please forgive me for being a n00b at English.

Create a new World instance? What the hell are you doing?

 

@OP: Is "player" a field or local variable accessible where that line is? Show more of your code.

Sorry to beat a dead horse, but it has to be done. How does the golden apple do it? I'm going to give you a hint because you are not getting it. The name of the method you should be implementing starts with on and ends with Eaten. Those are the hints you will be getting, do with them what you will.

Also, just as a side note, there are much better/simpler/cleaner ways to deal with unlocalized names than Pahimar's. Like this one, created by diesieben:

public void setBaseName(String base) {
    setBlockName(MyMod.MOD_ID + "." + base);
    setBlockTextureName(MyMod.MOD_ID + ":" + base);
}
