Make an item go invisible.

Topic category: Help with Minecraft modding (Java Edition)

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).

Yes the method needs to be inside the last }

Like this;

public class SplashSmokeBombPotionStartedappliedProcedure extends SmokeBombsModElements.ModElement {
	public SplashSmokeBombPotionStartedappliedProcedure(SmokeBombsModElements instance) {
		super(instance, 2);

		if (dependencies.get("x") == null) {
			System.err.println("Failed to load dependency x for procedure SplashSmokeBombPotionStartedapplied!");
			return;
		}
		if (dependencies.get("y") == null) {
			System.err.println("Failed to load dependency y for procedure SplashSmokeBombPotionStartedapplied!");
			return;
		}
		if (dependencies.get("z") == null) {
			System.err.println("Failed to load dependency z for procedure SplashSmokeBombPotionStartedapplied!");
			return;
		}
		if (dependencies.get("itemstack") == null) {
			System.err.println("Failed to load dependency itemstack for procedure SplashSmokeBombPotionStartedapplied!");
			return;
		}
		if (dependencies.get("world") == null) {
			System.err.println("Failed to load dependency world for procedure SplashSmokeBombPotionStartedapplied!");
			return;
		}
		Entity entity = (Entity) dependencies.get("entity");
		int x = (int) dependencies.get("x");

		Tic = (double) 0;
		X = (double) (entity.getPosX());
		Y = (double) (entity.getPosY());
		Z = (double) (entity.getPosZ());
		world.playSound((PlayerEntity) null, x, y, z,

	}

import net.minecraftforge.client.event.RenderPlayerEvent

Import that, but you have some other errors, can you post code again?

Because I suspect you got rid of these

package net.mcreator.smokebombs.procedures;

Dont get rid of the imports

I fixed the errors (you cropped off some import lines), but it doesn't make me invisible now

The speed still works right.

Two possible issues.

1. The NBT maybe not synced to the client.

2. The class may not be registered.

Change this;

	public SplashSmokeBombPotionStartedappliedProcedure(SmokeBombsModElements instance) {
		super(instance, 2);
	}

To this;

	public SplashSmokeBombPotionStartedappliedProcedure(SmokeBombsModElements instance) {
		super(instance, 2);
MinecraftForge.INSTANCE.register(this);
	}

I am not on my computer. So you are going to have to find the import for MinecraftForge.

But I believe if you delete a few letters and place them back it should pop up and auto-import.
