Is the package supposed to be com.hogans.craft.entities.EntityMage ?

 

or is it supposed to be com.hoganscraft.entities.EntityMage ?

[Soulas97]

com.hogans.craft.entities;EntityMage

That error is caused when Java can find your class at compile time but not at runtime, so your classpath has a problem, I'm guessing that perhaps your mod folder structure is not right, so Forge is only finding some of your mod source, not all of it.

 

Your mod file should look something like this structure

And dude that package naming convention is just begging for subtle bugs

hogans.craft

Hoganscraft

HogansCraft class just for good measure:)

 

package names should be lower case to avoid confusing the other folks out there

 

(And - to avoid subtle bugs due to Windows not being case sensitive, but zip files are - perhaps this is your problem here too?)
