STEPS:
1. Created gameObjects - Cube, Sphere, Finish Line. Created UI elements - Canvas then Button & Text.
2. Added raceLogic script to an empty gameObject, raceLogic. Added finishLine script to gameObject, finishLine.
3. Wrote the startGame() method to get the shapes to move. Used transform.position to keep the shapes in the same spot before the race starts. Once "Start Race" button is hit, the shapes' speed were changed from 0 to a positive value and text is changed to "Go!"
4. Wrote the OnTriggerEnter() method for FinishLine. Used the tags to determine wether or not the cube wins or the sphere. Used the same method to change the text to display which shape wins.
5. Altered raceLogic so that if the shapes get to a certain point, they stop so it looks more realistic (can take this out if you need).
