Modifying the GuiIngame class with a CoreMod

[kirby2ig]

I have a Minecraft jar mod that modifies the GuiIngame (btz) class and changes the position of the scoreboard on the screen. I used this tutorial with my own modified btz class.

http://www.minecraftforum.net/forums/mapping-and-modding/mapping-and-modding-tutorials/1571568-tutorial-1-6-2-changing-vanilla-without-editing

When i ran the game with the mod, I got this error.

Any advice?

[LexManos]

Do note coremod. We have plenty of events for you to do whatever the heck you want on the screen  -.-

[Ernio]

Jar modding is not supported as of very long ago (pre-1.6?)

 

Lookup Forge Events, particularly:

RenderGameOverlayEvent

 

Note: Mind that this event has phases - always choose a phase, otherwise code will run multiple times.

[kirby2ig]

Actually, I have never written a mod that is not a jar mod (unless you count a Bukkit plugin as a mod). Maybe it is time for me to move over to Forge. The only time that I have ever used Forge was when I was playing Tekkit.
