So, I used to be able to do this with modloader but I want the mod to be smp so I am making it completely forge.

 

I want it so when I right click it with my item is adds potion effects (done) and displays a message in chat.

 

Code so far:

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
	    {
	    if (par3EntityPlayer.capabilities.isCreativeMode)
	    {
	    return par1ItemStack;
	    }
	    else if (par3EntityPlayer.ridingEntity != null)
	    {
	    return par1ItemStack;
	    }
	    else
	    {
	    --par1ItemStack.stackSize;
	    par2World.playSoundAtEntity(par3EntityPlayer, "random.orb", 0.5F, 0.4F / (itemRand.nextFloat() * 0.4F + 0.8F));

	    if (!par2World.isRemote)
	    {
	    (par3EntityPlayer).addPotionEffect(new PotionEffect(Potion.regeneration.id, 40, 4));
	    (par3EntityPlayer).addPotionEffect(new PotionEffect(Potion.damageBoost.id, 400, 4));
	    }

 

Thanks!

Try:

par3Entityplayer.addChatMessage("Your message here");

 

Thanks, no errors, but nothing appears in the chat

 

EDIT: FIXED! Thanks! I just had the method renamed and was using the wrong item...
