I would like to see the a RenderHUDEvent that allows you to draw on the players in-game screen. I know there are methods which makes this possible but once you open a GUI it renders over that GUI as well. With a RenderHUDEvent your renders will render behind Gui's. See code below for implementation.

 

package net.minecraftforge.client.event;

import net.minecraft.client.Minecraft;
import net.minecraftforge.event.Event;

public class RenderHUDEvent extends Event {
        
        public final Minecraft mc;
        public final float partialTick;
        public final boolean guiOpen;
        public final int mouseX;
        public final int mouseY;
        
        public RenderHUDEvent(Minecraft mc, float partialTick, boolean guiOpen, int mouseX, int mouseY) {
                this.mc = mc;
                this.partialTick = partialTick;
                this.guiOpen = guiOpen;
                this.mouseX = mouseX;
                this.mouseY = mouseY;
        }
}

 

 

GuiIngame.java

if (this.mc.playerController.func_78763_f() && this.mc.thePlayer.experienceLevel > 0)
        {
            this.mc.mcProfiler.startSection("expLevel");
            flag1 = false;
            i1 = flag1 ? 16777215 : 8453920;
            String s = "" + this.mc.thePlayer.experienceLevel;
            j5 = (k - fontrenderer.getStringWidth(s)) / 2;
            k5 = l - 31 - 4;
            fontrenderer.drawString(s, j5 + 1, k5, 0);
            fontrenderer.drawString(s, j5 - 1, k5, 0);
            fontrenderer.drawString(s, j5, k5 + 1, 0);
            fontrenderer.drawString(s, j5, k5 - 1, 0);
            fontrenderer.drawString(s, j5, k5, i1);
            this.mc.mcProfiler.endSection();
        }

        MinecraftForge.EVENT_BUS.post(new RenderHUDEvent(this.mc, par1, par2, par3, par4));

        String s1;

        if (this.mc.gameSettings.heldItemTooltips)
        {
            this.mc.mcProfiler.startSection("toolHighlight");

            if (this.field_92017_k > 0 && this.field_92016_l != null)
            {

With use of RenderHUDEvent:

Just draw your stuff using a tick handler and the Tesselator. If you don't want it to draw over other Guis, check for this before drawing.

FMLClientHandler.instance().getClient().inGameHasFocus

If that returns false, don't draw your stuff. Simple.

I tried pretty much everything to draw behind gui, but never got the right result.

Okay here are some pictures of what I mean with my "problem"
