Zoey Lee - Final Project

Description:

This game simulates the classic "Trolley Problem" such that the user is tasked with choosing who dies in the given scenario. The user views the scenario and decides whether or not to pull the lever by clicking the corresponding buttons. Doing nothing is "letting 5 die" whereas pulling the lever is like "killing 1 person".

Technical Steps:

1. I created the main game scene and imported necessary assets (ie. trolley, tracks, decor).

2. Outlined out the TrolleySimLogic script for each function in the game.

----includes coroutine to sequentially call each function with added timers for improved experience.

3. Animated the trolley so that it moves on the track based on the input.

4. Added my particle-blood splatter-thingy on the people so that they look like they get run over.

----uses for loop to instantiate a bunch of blocks

5. Added a beginning and ending scene so that the user can play the game in a loop.
