Make an item go invisible.

Hi, I am trying to make a super invisibility potion (with a stack size of 16) , where even the potion disappears, I thought about swiping out the potion with a dummy invisible item but I'm not quite Shure how to do that (preferably with block coding).

You need to import;

import net.minecraftforge.client.event.RenderPlayerEvent;

What about "@SubscribeEvent"

You need to import that to, I dont have access to my computer anymore. But I think you can just do imports using (CTRL I)

so... um... what would I import exactly? this:

@SubscribeEvent public void renderPlayerPre(RenderPlayerEvent.Pre event) { if (event.getPlayer().getPersistentData().getBoolean("cancelrendering") == true) { event.setCanceled(true); } }

also, sorry for being so noobish

Alright, I just got home. This is what you are looking for;

import net.minecraftforge.eventbus.api.SubscribeEvent;

1. You can't use;

event.getPlayer().getPersistentData().getBoolean("cancelrendering")

or alternatively putBoolean because you aren't provided with the variable event.

But MCreators procedure provides you with the "dependency" entity.

So we can use;

entity.getPersistentData().putBoolean("cancelrendering", false);

2. The code is hard to read for me on the forum, so I fixed it up as best I could. But I think it may be better to set everything up first (the NBT and etc) in the MCreator Procedure editor. And then adding the RenderPlayerEvent last.

I was thinking the invisibility would get applied after the speed, then would be revoked after the while loop ends.
