1.12.2 - Info bar above inventory bar completely artifacted

I have isolated the issue in the following line of code:

Minecraft.getMinecraft().fontRenderer.drawStringWithShadow(etc)

 

I'm extremely confused as to why it's artifacting the xp bar, health bar, food bar and armour bar. Here's a portion of my code:

// the main code
public void postInit(FMLPostInitializationEvent event) {
    MinecraftForge.EVENT_BUS.register(new MyMod());
}

// MyMod class
public uiCreator;
public MyMod() {
    uiCreator = new UICreator();
}

@SubscribeEvent
public void onGui(RenderGameOverlayEvent event) {
    uiCreator.Create();
}

// UICreator class
public void Create() {
    Minecraft.getMinecraft().fontRenderer.drawStringWithShadow("MyMod", 2, 2, 0xffffff);
}

 

Effectively, the line which is causing the artifacting is `Minecraft.getMinecraft().fontRenderer.drawStringWithShadow("MyMod", 2, 2, 0xffffff);`. I don't understand why. I'm certain it's this line, as removing/commenting out any other portions of code do not fix the artifacting until I comment this line out. I'm extremely confused as to why this is occuring. If anyone has any form of insight, I'd greatly appreciate it

RenderGameOverlayEvent

RenderGameOverlayEvent gets called once per HUD element. It is called once for health, once for hunger, once for experience, etc. It is additionally called twice with Pre and Post subclasses. You need to 

  1. Subscribe to either Pre or Post instead of the parent event class
  2. Check whether the HUD type the event is fired for is the desired for your case. Otherwise you are drawing your text many times over which is not good for performance.

As for the "artifacting" issue:

When the game renders the HUD it binds the HUD texture once before drawing it. Rendering any text however binds a corresponding font texture. Since you are rendering in the middle of HUD rendering the font texture stays bound and is used to draw the rest of the HUD which leads to incorrect things being drawn. You need to either draw before/after all the HUD or rebind the HUD texture back.

Thank you for your response, however the hunger bar continues to be artifacted with Post. I'll try Pre and reupdate this comment. If I use Pre, everything will once again be artifacted, as you said, since it uses a different texture. Post will also artifact the hunger bar still.

 

Edit: I've solved the issue by checking `event.getType()`. Thank you!

    • I seriously don't know what happened. One night I closed my IDE (IntelliJ), and the next morning and opened it and tried getting to work only to find it was saying I was missing repositories? I haven't messed with anything gradle on my mod for weeks now, I tried deleted the .gradle cache in my personal folders, etc. This is what I get when I run with stacktrace, but I have no idea what any of this means: https://pastebin.com/WXXwHKvw I included the entire thing, because I don't know what's important and what's not.
