Please help me out of this problem.

Is your main mod class set up properly?

All the correct annotations?

Yes i have no errors.

 

This is my start line:

 

/*

* Basic needed forge stuff

*/

@Mod(modid="OpticalItems",name="Optical Items",version="1.0",acceptedMinecraftVersions="1.5.2")

@NetworkMod(clientSideRequired=true,serverSideRequired= false)

 

 

 

public class MainClass {

 

@Instance("MainClass")

public static MainClass instance;

 

@PreInit

public void postInit(FMLPreInitializationEvent event) {

 

 

}

 

And i starts up in Eclipse

your @Instance() line should actually have the name of the modID, not the name of the class

 

so it should be (from your example)

 

@Instance("OpticalItems")

  public static MainClass instance;

 

 

 

otherwise, what happens is FML tries to find a mod named "MainClass" to inject the main mod file into the instance field of your MainClass  (which it won't find, and hence the crash).

Fixed. I deleted some code and recode some stuff!

Now it works properly!

And i changed the @Instance

So thanks!
