This video was a big help when it came to creating my functional keyboard.
Initially, I was able to find some documentation that instructed how to create a working VR keyboard using hinge joints in each key, however this method proved time consuming and heavily buggy in its execution. In its place, I was able to follow the instructions on this video, linking up the keys to the display on the monitor. Now whenever a key is pressed, it adds text to the canvas on the screen, simulating writing on it.
Now with a functioning computer setup, I linked up the score system next to it, and created the concentration bar UI element above the PC itself to allow the player to keep track of the time they had left.
