I have made changes to the EntityPlayer class stored in net.minecraft.entity.player however when I recompile and reobfuscate my mod, then zip it up and put it in my forge mods folder for testing, the changes to EntityPlayer don't appear in game.  What is the proper way to make changes to the EntityPlayer class?  Am I going about this in the right way at all?

If you wrote something into EntityPlayer class, then you're doing it wrong.

thats because vanilla change are not allowed (everything under net.minecraft* )

make a coremod if you absolutelly need it

Thanks for the info Is there any good way to do this without creating a coremod?

depend on what you're trying to do, theyre might be a way to NOT make the base class change

 

else if you NEED to make base class change you can leave your mod in 1.5.2 and insert the modified files inside minecraft.jar but you're breaking compatibility with other mods

Thank you for all the help   I think I want to make a coremod, but I don't know where to start.  How similar is it to standard modding?  Do you know of any good tutorials I could start with?

how are your java skills ? (my answer will differ )

I feel very strong with Java, I'm an experienced Android app developer and have done lots of work with Java and ActionScript which is similar.

 

I just don't know how to work with the minecraft Forge APIs yet as I actually just started modding yesterday

basicly forge is shipped with this library called ASM, this can modify java code at runtime (just before the game is launched, you basicly tell the JVM "use this instead" )

 

i dont have a tutorial for you but i only recently learned about how to use ASM myself, i think learning a bit of how java bytecode works helped a lot

 

here my thread i posted:

just read it and try to see what you need to know/use
