I'm trying to make a custom potion effect, and I've got everything working except the icon. The effect icon renders as just a transparent square. I know its loading something, because its not the black missing texture thing, and no errors are thrown in the console. But its not loading my texture file because I tried filling the whole thing with color and nothing loaded. I set the icon index to (0,0).

 

Potion effect:

    public static class ImmortalityEffect extends Potion
    {

		protected ImmortalityEffect() 
		{
			super(false, 8331833);
			this.setPotionName("effect.immortality");
			this.setIconIndex(0, 0);
			this.setRegistryName(Immortality.MODID + ":" + "immortality");
		}
    	
		@Override
		public boolean hasStatusIcon()
		{
			Minecraft.getMinecraft().getTextureManager().bindTexture(new ResourceLocation(Immortality.MODID + ":textures/gui/potion_effects.png"));
			return true;
		}
    }

 

The texture I'm using is attached

Ah, my mistake, I was just following an example. How exactly do I render an icon? I've never done any rendering before

I've been looking at it, and I kinda figured that was the correct approach. 

So, the deobfusticated vanilla potion class just has an empty method for renderInventoryEffect. is there another place I should be looking?

Ok, I did it. I found an example on another mod's github. The main thing i needed was how big to set the icon and which overload to use.

 

For anyone with a similar problem, this works just fine in 1.12.2 with a 16*16 icon:

 

@Override
		@SideOnly(Side.CLIENT)
		public void renderHUDEffect(int x, int y, PotionEffect effect, Minecraft mc, float alpha)
		{
			mc.renderEngine.bindTexture(icon);

			Gui.drawModalRectWithCustomSizedTexture(x + 3, y + 3, 0, 0, 18, 18, 18, 18);
		}

		@Override
		@SideOnly(Side.CLIENT)
		public void renderInventoryEffect(int x, int y, PotionEffect effect, Minecraft mc)
		{
			mc.renderEngine.bindTexture(icon);

			Gui.drawModalRectWithCustomSizedTexture(x + 6, y + 7, 0, 0, 18, 18, 18, 18);
		}

Thanks for the help diesiben!

 

EDIT: there seems to be a bug where the icon is rendered over a speed effect icon.
