To randomly spawn our items, we need to generate a random number between 0 and the number of items we have, and then use that in a switch statement. As stated previously, there isn't one approach to procedural generation, so there will be other methods to doing this.
Let's add in the number generation and switch statements to choose which item to spawn. The updated Game::PopulateLevel function should look as follows:
