If I call SCoreEntityPlayerMP,SCoreEntityPlayerSP using PlayerUtil, I get a null value

Question, what is the problem?  I'm not going to dig through your code unless a problem is presented.  Alright, have you tried to see if it is attempting to check for the new EntityPlayer classes before they are even declared?

No, but how to do it? Sorry for bad English.

In your core, when is the PlayerUtil initialized/referenced?  You should declare your entities in your pre-init and then try using your PlayerUtil in post-init.

I already did, but can you explain how did it here: https://github.com/micdoodle8/Galacticraft/tree/master/common/micdoodle8/mods/galacticraft/core/entities/player
