I want to make my own custom launcher for minecraft, where player selects single player mode or multiplayer mode inside launcher instead of game main menu. When player launches minecraft, it goes directly into game world without showing the main menu.
I am new to minecraft development, but I have experience with java programming. I don't know where to begin with. Is there a tutorial about buiding custom launcher? If I want to launch minecraft with parameters like server and port, how could I launch it, which jar file to launch?
Many thanks in advance.
