Space Invaders

Space Invaders, flavored in Python. Written with pygame, as an interactive game for users to enjoy with their keyboard and mouse. Features health status, increased levels with corresponding difficulty, and a friendly user interface.

Background

This program is written in python, for the user functionality and calculation aspect of the game. It utilizes a module (namely Pygame) in order to offer a GUI for the game, along with linking assets (such as images for a background, main character, or invaders) to the back end of the program.

How to play

• Extract the code by double clicking on it (on Mac) or right clicking and hitting "Extract All" (on Windows).
• Open the code in your preffered IDE or text editor, while setting the syntax to python.
• Install the needed dependencies by running pip install pygame in your terminal (run pip3 install pygame if you have multiple versions of python on your computer, or if you have a Mac)
• Run the program by clicking the nessesary buttons in order to do so (you can also run the program in the terminal by running python3 main.py after navigating to the correct directory \downloads\space-invaders-master.

Rules of the Game

• You are the main space ship, with the health bar. Your job is to keep the ships from crossing you (or "invading" your territory).
• You must keep the space ships from crossing your current spaceship position, or you lose a life out of your given 5.
• You must also maintain your health bar, as if it runs out you lose the game. These "invaders" will be shooting at you, and if your ship comes into contact with their bullet or their spacecraft itself, you lose a portion of your health.
• You can move the ship anywhere on the game board by using the WASD keys.
• You can shoot back at the "invaders" by hitting the spacebar.
