If anyone is interested, there's this camera follow project that contains 2 player nodes and a camera node that follows both players similar to that of a fighting game. It was from the GD QUEST Demos.
I managed to program in 8-way movement for both player nodes. However I can't get the camera to rotate and keep both players in view.
Feel free to take a look and whoever takes this on can do a better job than I could.
