1. i can't believe we didn't have a character prefab. woops! so i added
it with the model. the model is obviously temporary. I only added it so
that i can start working with it later

2. I made it so that you can't interact with the same object more than
once.  It was done by just making a public variable called
bHaveInteracted and just flipping that to true after interacting. I
should have made it private technically and made a public function to do
that but this was more a proof of concept that objects are pass by
reference in unity. go figure. so now you can't interact more than once

3. as for character sprites and stuff, i've been thinking of a way to
tackle that. we'll eventually have to talk about it in person or
something so that we can iron out the kinks.
