i looked into versions/1.6.2-Forge9.10.0.804 and effectivelly the class is not there but i used the installer.

 

not sure why/where i screwed up

 

i based my method off this tutorial:

http://www.minecraftforum.net/topic/1854988-tutorial-162-changing-vanilla-without-editing-base-classes-coremods-and-events-very-advanced/

the "replcaing a whole miencraft class" part

Isn't there some special parameter to add to the java command line ?

Like -disable_consistency_check=true ?

i might be wrong but i kindof doubt that because it would mean that people would HAVE to add option to launch. Afaik mods/coremods are suppose to be a drag n drop thing and adding this kind of option inside the coremod wouldnt make sens as java is already launched when this file is read.

 

maybe im wrong though

 

From Optifine installation:

Click "Edit Profile"

- Select the checkbox "JVM Arguments" and in the field next to it add

"-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true"

- Click "Save Profile"

implying optifine is REQUIRED to use forge and coremods

Nope, just taking as an example. Why would it be any different for your coremod ?

because im pretty sure that its not required as i havnt seen mention of that anywhere

Are you sure you can return null there ?

@Override
public String getModContainerClass() {
	return null;
}

@Override
public String getSetupClass() {
	return null;
}

Are you sure you can return null there ?

@Override
public String getModContainerClass() {
	return null;
}

@Override
public String getSetupClass() {
	return null;
}

 

Mod container class is only required if you want to have mod metadata. In which case he doesn't (I know this because I do). Stup class... I made a coremod for 1.6.2 and didn't have that running either. So no its not needed. A coremod is like a paxel. It is a lot of different functions all put together. In this case though, all those methods are like the mould needed for the paxel, but I only want the shovel part of it. I also only have that mould. So I only fill in the shovel section. Simple as that.

Well maybe you can help him more than i ?

 

I found this thread with same issue here

ding ding ding, bonus point to GotoLink because im an idiot who cant search properly, i am returning null in my transform method meaning every class that gets through will be erased causing the class to simply not exists

 

derp mode enabled

Not really

Well, not quite the methods that affected the transformer classes, but still. Good call Gotolink

Forge has a coremods folder in the .minecraft directory. I'm pretty sure your mod should go in there. In your main post, you stated that you placed the mod in the mods folder.

not in 1.6.2, in this verison everything goes in the mods folder

OK sorry, I did not know that.

all good ^^

 

to future reader, if you need to change "net.minecraft.client.Minecraft" via ASM, good luck ^^ i was never able to do it i foudn another way around doing what i wanted (version 1.6.2)

at least its not feasable via replacing the whole class
