Im making a mod that is supposed to draw text on the screen, I'm doing this by creating a GUI and rendering it on the RenderGameOverlay event like this

@SubscribeEvent
    public void onRenderGui(RenderGameOverlayEvent event) {
	new ModList(Minecraft.getMinecraft());
}

and

public class ModList extends Gui{

public ModList(Minecraft mc) {
	drawString(mc.fontRendererObj, "Test", 10, 10, 16755200);
}
}

The problem I am having at the moment is that when I draw the string for some reason it draws the text twice like in this image

Does anyone know why this is occurring?

hmm i managed to fix my own problem by instead of using the RenderGameOverlay event use RenderGameOverlay.Text i don't understand why this changed anything but it works... i guess

Because there are multiple RenderGameOverlay sub events, and how event buses work. When you subscribe to RenderGameOverlay, you will recieve all events that are child classes of RenderGameOverlay. So you are rendering your text for each element of hud rendered.
