[1.7.10] New overlay to acess wich "Raw" LWJGL features

Recommended Posts

I wonder if its possible to code a complete new overlay, wich you can access with LWJGL code (for example drawing quads or drawing text with slick-Util)

 

i tried it with a custom gui, but it seems not to like Open-GL directly (or Slik-Util)

i managed it to get a string with Arial-Font drawn on screen(that's what slick-Util does), by extending gui and registering a RenderGameOverlayEvent(and put the slick-Util code in the funktion)

 

But the Hotbar somehow disapears and Minecraft is about 1Frame each 15seconds...

 

 

so question is: is it possible to get it to a HUD, or is it possible to get a new overlay?

Ups i write GuiDraw event instead of RenderGameOverlayEvent...

sry, that doesnt work:

 

GUI Code

import cpw.mods.fml.common.eventhandler.SubscribeEvent;

import net.minecraft.client.Minecraft;

import net.minecraft.client.gui.Gui;

import net.minecraftforge.client.event.RenderGameOverlayEvent;

import org.newdawn.slick.*;

import org.newdawn.slick.Color;

 

import java.awt.Font;

 

public class MsgGui extends Gui

{

    Minecraft mc;

 

    public MsgGui(Minecraft mc) {

        super();

        this.mc = mc;

    }

 

    org.newdawn.slick.TrueTypeFont font;

    @SubscribeEvent

    public void RenderHUD(RenderGameOverlayEvent event) {

 

        System.out.println("Rendering HUD!");

 

        Font awtFont = new Font("Arial", Font.BOLD, 24);

        font = new TrueTypeFont(awtFont, true);

 

        font.drawString(100, 50, "THE LIGHTWEIGHT JAVA GAMES LIBRARY", Color.blue);

    }

}

 

 

and this happens:

(well can't upload an image direktly, so here's the link:)

https://dl.dropboxusercontent.com/u/56021465/Unbenannt.PNG

 

you may recognize the big blue Text(thats what it should look like), but also the ugly experience/Hunger-bar...

 

any suggestions?

 

PS: why game is in Pause menu?

can't manage to get back in, seems like 1 FPS per minute or so, so i take a screenshot...

ah, the first priority is to get it working, thats why i load all things inside the RenderEvent^^

 

i know, loading the font and stuff have to go outside the render...

 

Well, but i think i missed that i can use the eventtype... Thx for it!

 

so, now it looks like this:

 

if (event.type == RenderGameOverlayEvent.ElementType.HOTBAR) {

 

            //System.out.println("Rendering HUD!");

 

            font = new TrueTypeFont(awtFont, true);

 

            font.drawString(100, 50, "THE LIGHTWEIGHT JAVA GAMES LIBRARY", Color.blue);

        }

 

than it all works correct (but with weak performance)

 

but if i move the line

'font = new TrueTypeFont(awtFont, true);'

 

out of the render Funktion, it looks weird(kinda like blue Boxes);

 

Is this because the EventType.Hotbar(renderer) scratched it up?

is it possible to add a new EventType (or a event) wich is more suitable(I think about an event that extends RenderGameOverlayEvent)?

or should i just use another eventType?

You don't need a new EventType. Besides the EventType you also need to choose between Pre and Post (both subclasses of RenderGameOverlayEvent). If you don't specify any, you receive both and as such draw twice per frame, once before the specified element and once after. If you just want to draw something you usually want .Post so you don't mess with the texture.

Ok, managed it:

 

public class MsgGui extends Gui

{

    Minecraft mc;

 

    public MsgGui(Minecraft mc) {

        super();

        this.mc = mc;

    }

 

    Font awtFont = new Font("Arial", Font.BOLD, 24);

    org.newdawn.slick.TrueTypeFont font;

 

    @SubscribeEvent

    public void RenderHUD(RenderGameOverlayEvent.Post event) {

 

 

        if (event.type == RenderGameOverlayEvent.ElementType.HOTBAR) {

            font = new TrueTypeFont(awtFont, true);

            font.drawString(100, 50, "THE LIGHTWEIGHT JAVA GAMES LIBRARY", Color.blue);

        }

    }

}

 

Result: (@11FPS)

https://dl.dropboxusercontent.com/u/56021465/2015-01-10_20.52.31.png

 

Next Step(note the line: "font=new TrueTypeFont...")

public class MsgGui extends Gui

{

    Minecraft mc;

 

    public MsgGui(Minecraft mc) {

        super();

        this.mc = mc;

    }

 

    Font awtFont = new Font("Arial", Font.BOLD, 24);

    org.newdawn.slick.TrueTypeFontfont font = new TrueTypeFont(awtFont, true);

 

    @SubscribeEvent

    public void RenderHUD(RenderGameOverlayEvent.Post event) {

 

 

        if (event.type == RenderGameOverlayEvent.ElementType.HOTBAR) {

            font.drawString(100, 50, "THE LIGHTWEIGHT JAVA GAMES LIBRARY", Color.blue);

        }

    }

}

 

That happens: (@1300FPS (yes its that high!))

PS: there is a potion Effekt, you can ignore the blue boxes up and left down

so, i wrote this class:

 

public class MSGGuiEnabler {

    public boolean firstEvent = false;

    @SubscribeEvent

    public void initMsgGui(RenderGameOverlayEvent event)

    {

        if (firstEvent == false) {

 

            System.out.println("GUI ENABLED!");

 

            MinecraftForge.EVENT_BUS.register(new MsgGui(Minecraft.getMinecraft()));

            firstEvent = true;

        }

    }

}

 

Result is the same as the last pic i posted...

You don't need 2 event handlers... In the event handler you already have do that lazy initialization. Also:

 

Besides the EventType you also need to choose between Pre and Post (both subclasses of RenderGameOverlayEvent). If you don't specify any, you receive both and as such draw twice per frame, once before the specified element and once after. If you just want to draw something you usually want .Post so you don't mess with the texture.

I have 2 examples of custom overlays, with explanation inside the code here:

 

https://github.com/Nephroid1/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/overlay_simple

https://github.com/Nephroid1/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/overlay_advanced

 

Though these are working for version 1.8, the same concept applies to 1.7. The first one just changes the vanilla overlay a bit, and the second one adds in a custom HP bar.

 

These should be enough to solve the rest of your problems.

Allright, i managed it to get quads drawn, but i've got a problem with the texture binding...

 

Complete class: http://pastebin.com/ufrai5BY

 

and heres the result: https://www.dropbox.com/s/lvufkd7qapt2cic/2015-01-11_22.15.00.png?dl=0

 

the first frame you are able to see the correct Texture, but than it draws the icons.png texture...

i try to unbind(release) the texture, but then the item-Bar and everything gets white...

 

i need to place the right texture back...

ah and when i try to load the image every frame (which of course is little stupid because the VRAM reach its max very fast), the texture gets drawn right, but than the Air bubbels disappeare

 

any suggestions?

 

 

EDIT: Well nevermind, seems Forge don't let you play directly with GL Texturebinding, you have to use "mc.renderEngine.bindTexture(<Texture>);"

so that means drawing fancy Text with Slick-Util (or using other OpenGL-Utils) isn't possible :(

    • I know I'm the worst, but where would that be in my code to create a new instance?
    • the class does not change the result, but i would recommend you to create a new class for the Item a thing you need to do is create a new instance of the class inside the RegistryObject instead of using the Item class  
    • There happened to be a few simple logic mistakes. I now get the correct sound out and a correct value is printed out on server, but on client it is still 0 for some reason.
    • Not sure, I haven't dug into the minecart code that much. The only problem I see is that this: Math.pow(targetVelocity, 2) - Math.pow(entryVelocity, 2) Is guaranteed to return a negative value, which when multiplied against entity motion would cause the entity to reverse direction.
