[UNSOLVED] - Custom Helmet Render-Overlay

Recommended Posts

Hi guys

 

I am having a rather tough time figuring out what my problem is.

 

Basically, I would like a helmet that renders a "pumpkinblur" type overlay and then adds an Overlay HUD (bit like the one in one of the tutorials) - that shows things like Armor Usage, Tool Usage, Potion Effects, etc, etc...

 

1 - Even though my coding seems fine, it simply will not render

 

2 - how do I even go about adding a HUD with armor values and things (only while this item is equipped) ?

 

 

MOD CODE:

{

  public final static String ID = "HudPumpkin";

      public static ItemArmor HudPumpkinItem;

      @SidedProxy(clientSide = "els236.mods.hudpumpkin.client.ClientProxy", serverSide = "els236.mods.hudpumpkin.CommonProxy")
      public static CommonProxy proxy;
       
      
      //
      // Mod entry points
      //  
      @PreInit
      public void preInit(FMLPreInitializationEvent event)
      {
    	  
      }
      
       @Init
       public void load(FMLInitializationEvent event)
       {
    	   HudPumpkinItem = (ItemArmor)(new ItemArmor(3250, EnumArmorMaterial.CLOTH, 2, 0)).setUnlocalizedName("HudPumpkin");
    	   HudPumpkinItem.setCreativeTab(CreativeTabs.tabCombat);
    	   
    	   GameRegistry.registerItem(HudPumpkinItem, ID + HudPumpkinItem.getUnlocalizedName());
    	   LanguageRegistry.addName(HudPumpkinItem, "HUD Pumpkin");
       }
       
       @PostInit
       public void postInit(FMLPostInitializationEvent event)
       {
         MinecraftForge.EVENT_BUS.register(new HudPumpkinOverlay(Minecraft.getMinecraft()));
       }
       
}

You don't have the @ForgeSubscribe annotation anywhere, so even if you register your overlay class with Forge, it's not going to find any methods that it needs to call back.

 

@ForgeSubscribe(priority=EventPriority.NORMAL)

 

Also, I believe that you should be extending Gui, not GuiIngameForge.
