Render Item Icon

Note

When rendering an icon on screen you should use RenderGameOverlayEvent.

Render.renderItemIcon(ItemStack stack, float x, float y, float scale)

This will render an item icon on your screen.

Example

Tip

You should check Minecraft.getMinecraft().currentScreen to limit rendering your item so it only shows up when you want it to, like in the example below which will only render the item when no GUI is open.

@EventTarget
public void onRenderGameOverlay(RenderGameOverlayEvent event) {
    if (mc.theWorld == null) return;
    if (mc.currentScreen != null) return;

    final ItemStack itemStack = new ItemStack(Items.diamond_sword);

    Render.renderItemIcon(itemStack, 10, 10, 1);
}
