Yeah the title pretty much explains every thing. any help will be appreciated.

so your trying to change the code itself when you right click the item? or are you just trying to change the name of the item when you right click with it?

im trying to change the name of the item when you right click with it

 

Make a string list with all the possible names and use an index number which increases each time you right click the block.

I cant make a list, I have a item that generates a random number using NBT and displays it on addinfo, but i also want it to display on the name

Just re-register the item in the language registry. I think it should overwrite the old name.

@Override
public String getItemDisplayName(ItemStack par1ItemStack) {
   //return whatever you want
}

make an array string for the names ,use metadata for the blocks and in your languageRegistry just do this

 

for(int i = 0; i < <block_string array>.lenght; i++){

    LanguageRegistry.addName(new ItemStack(<block id>, 1, i), <block_string array>);

}

 

(the words between <> are things you have to fill in yourself)

 

and then just make sure that whenever you rightclick the block you switch your metadata (don't know what method that is anymore, i think something aroud onBlockActivated and some paremeters but i'm not sure)

 

Hope it helped!

LanguageRegistry

 

Noooooo.....Don't use the language registry.

That's what language files are for!  So much easier and it makes translation work easier because you don't have to write code to do it.

Like Draco said, but I'll explain it more.

 

Use the onItemRightClick method to activate this method:

 

@Override
public String getItemDisplayName(ItemStack par1ItemStack) {
   return "replacewithitemname";
}

 

If you wish to switch back and forth between two different names.

Then make an array that switches between two variables, and depending on which variable use the code above.
