Node tree for mouse control navigation

I tried following a couple of tutorials on navigating a cube with mouse, except some nodes that are used in the tutorials are not found. Either they are called something else now or there is news ways of doing this. The tutorial I followed
Recreating Pac Man. I followed the video step by step, I tried substituting different things. I snipped what the tutorial said to use. Just need to know how to do this now. Thank you in advance!



Here is a small example file that uses the latest nodes. Let me know if this helps.
