Prevent forge from changing UUID

[AlekBardzo]

I stumbled upon the solution sometime ago, yet cant find it now. My point is that everytime I run minecraft from eclipse, it assigns a random player name and uuid. How do I prevent that so it launches with constant uuid ? There was a parameter that should have been called somewhere, correct ? Just a hint please ?

-username [username] -password [Password] in the build configs "Program Arguments"

 

Some friendly advise, if your using some form of source control and publishing it online, make sure not to publish your project data...

 

You know password and all

 

Note: -password is optional, the UUID will not change but will not be the same one Mojang Servers give you.

I did as You said, only with uuid, since I'd be checking uuid's internally and want to test if data saved in the world will properly belong to a player that created it, no personal paswords or such...

The -username only starts the game with your Username, the UUID will never change when people use the mod as Mojang gives it to you.

 

Setting your username will give a constant UUID, albeit still different then the one on the Mojang servers unless you supply the password in your Build Params.
