Been attempting to create a ring type object that will teleport the player using it to a specific spot. I've got the teleportation bit figured out, but I'm not sure how to A) Check if the player is on a server, and B) if the player is opped.

 

I found the isOp command while rooting through files, but not quite sure on how to use it.

 

package net.minecraft.src;
import java.util.Random;

import net.minecraft.src.forge.*;

public class GMRing extends Item implements ITextureProvider {
public GMRing(int i) {
	super(i);
	maxStackSize=1;
}

public boolean hasEffect(ItemStack par1ItemStack)
    {
        return true;
    }

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
        {

		if (isOp())

            if (!par2World.isRemote)
            {
            	par3EntityPlayer.setPositionAndUpdate(0, 70, 0);
            }

            return par1ItemStack;
        }

}

For those curious

if (isOp(par3EntityPlayer)) {

 

}

 

should work

 

also, take your stuff out of net.minecraft.src
