In any RTS game, you can select 3D object with the mouse, that's what i call picking. Another example is engine like Blender or Maya, where you can select units with "picking " in the editor. I would like to have a invisible GUI in game, to be able to control the mouse (easy part). Then, when the player click on an unit or a block, I would like to know which unit or block he has clicked on.

Hello, for a mod I need make a picker to select a block or an entity with the mouse in Minecraft, something like an OpenGL picker How can i do that ? Thank you
