[UNSOLVED] - Custom Helmet Render-Overlay

[Els236]

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) ?

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.
