在Eclipse中运行时的Minecraft Coders Pack错误

Question

Okay I am trying to make minecraft mods using eclipse. I used this video to set it up. I added both ModLoader and GuiApi to the Jar files before decompiling. It works until I try to test it in Eclipse then I get these errors:

    Failed to load mod from "mod_HeroesGuild.class"

    ... 3 more

I am new to programming and I don't have any idea what to do... The run system starts minecraft the mojang logo appears but then I get a white screen! Thanks!

Answer 1

I found a forum where someone had the same error:

http://www.minecraftforum.net/topic/236195-crashing-after-mojang-logo-problem-solved/

The answer they give is to reinstall , via instructions at:

http://www.minecraftwiki.net/wiki/Tutorials/Minecraft_Help_FAQ#Reinstalling_Minecraft

...and the poster replies:

didn't think to delete the whole .minecraft.
Problem cured.

Remember to back it up first.

Underlying cause

I'm thinking your SDK is somehow loading from/conflicting with your existing Minecraft install.

This is because .minecraft is the folder under the Application Data folder that contains minecraft user/runtime data. Basically, your save game data, and the program's cached data.
