How to play "Raiden 2".

Set up the framework for the game using comments.

Every 2D game follows the same basic structure: create and initialize variables, create objects, game loop, read user inputs, update the sprites/surfaces, adjust the location of the sprites. here we will start by outlining this using comments.

Load the level into a 2D array.

We will be building a level that has a camera that follows the ship around. In order to accomplish this, we will need to build the level using a 2D array of characters that each represent a surface that is 32 by 32 pixels.

Define the Platform class.

You will need to define a class that has an image and a rect. The dimensions of the image will be 32 by 32 pixels. You will need to take in the x and y position as parameters to the constructor.

Create the Platform objects.

You will need to have a nested for loop that will iterate through your 2D array. For each character "P" in the arrays you will need to create an object of type Platform and pass it's x and y position to the constructor.

Review the map building algorithm.

Create a container and use it determine the ship’s initial position.

A container is a rect that describes the world the ship exists in. If we create one, we can use it to more easily set boundaries for the ship and initialize the ship's position at the start of the game.
