Problem with any forge intended to replace modloader.

[balu88]

I've tried to install a mod, which requires Forge 3.3.8.148 or later. So I tried to update my forge.

It did not work.

So I reinstalled my minecraft and tried to install only the forge client 3.3.8.152 (the first recommended version after 3.3.8.148), but when I started the game it froze by a screen showing "Updating minecraft, done loading". Then, when I tried to launch the game with MCPatcher's Test Minecraft button, it worked.

So I tried it with some mods:

I tried it with OptiFine HD S C3, it worked.

I tried it with Computercraft (with and without optifine), but it crashed.

I tried it with Portal Gun v2 (with and without optifine), but it crashed.

And it gave me this error messages.

I think the problem is with newer forge, because these two mods worked with a few earlier forge versions, with every version which used risugami's modloader.

Sorry for the bad English, I'm from Hungary.

How the fuck do so many people install mods incorrectly.

Give the full exact path to your mod_ComputerCraft.class file.

[Cloudy]

You're using MCPatcher. Don't. For some reason, it fubars FML's mod loading so that it thinks every folder in the .minecraft folder is actually in the jar. This is no problem for zip/jar mods, as they'll get handled later and not loaded as a .class file, but for ComputerCraft which is a folder mod, it will try and load it at the wrong time.

[LexManos]

Ah, ya thats cuz you're doing something really stupid and putting everything into the jar.

Thats what MCPatcher does...

Don't use MCPatcher use the plethora of other tools out there that install things properly, or install things yourself.

[balu88]

W W W Wait a second! I did install the computercraft properly, like I mentioned, it worked with older versions of forge. I did put the extracted computercraft folder in the mods folder, like the descriptions of computercraft ordered me.

[balu88]

And I used MCPatcher 'cause the minecraft produced the freezing error I described before.

[Zero]

As for Forge, the freeze on the update screen usually means you've forgotten to delete the META-INF folder within the minecraft.jar after installing it.

 

As for the other mods...

 

• Optifine: goes into the minecraft.jar
  
• PortalGun: all of the mod files are contained inside of a folder within the .zip you downloaded of it. That means you need to create a new .zip file in the *.minecraft/mods directory, and drag the contents of said folder into it.
  
• ComputerCraft: same steps as PortalGun.
  

[LexManos]

You installed computercraft in some place

that makes FML think it is in the mods.computercraft package.

Zip your .minecraft folder and send it to me.

Don't feel like arguing over things that can be proven fairly quickely.

And I used MCPatcher...

 

Don't use MCPatcher! It is MCPatcher which causes this very issue - I have experienced it many times with support queries on the ComputerCraft thread on MCF.
