I have tried to update my mod to 1.7.10, but I for the last error I am trying to fix I need to get the owner's name to use the player in a chat method. This is for 1.7.2:

 

EntityPlayer player = worldObj.getPlayerEntityByName(this.getOwnerName());

 

But there is no getOwnerName() method.

 

 

Which class calling this method?

My entity class, but it is inside my own method.

I only played around a bit with 1.7.10, but I did noticed on several of the old commands that used player names it uses gameprofile and a few other items.  Look around at the class the method is in and you will find the new ways of doing things.

Never mind I think I figured it out. It was the same sort of thing but the method was a func one so I didn't know exactly what it did.
