[1.10.2] Getting the number of players in world [solved]

[DjCtavia]

Hi guys,

well, I have some trouble on modding, that like maybe 1 hours i'm on and, I don't get It...

Actually is my first time on modding but whatever.

 

I tried to get number of player when using an item. Then I use like it:

 

@Override
    public ActionResult<ItemStack> onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn, EnumHand hand) {
        if (!worldIn.isRemote) {
            playerIn.addChatComponentMessage(new TextComponentString(worldIn.playerEntities.size()));
        }
        return super.onItemRightClick(itemStackIn, worldIn, playerIn, hand);
    }

I absolutely know I can't do like this. I have some experience in C and then I tried something else like getting the last index of the list,

but after I can't do anything with the "Int" I can't do the function "ToString()".

 

Thank you for helping me

Did you try something like... ""+worldIn.playerEntities.size() ?

Because a raw integer value isn't terribly useful. You'd probably really want to display something like "5 players in world" which would be worldIn.playerEntities.size()+" players in world" which wouldn't have your int->string conversion problem.
