AIM To make a game with animation and graphics as a project for Computer Graphics

OBJECTIVE To build a game using a programming language. The game is a basic ‘Shoot ‘em up’ type, where the player shoots his enemies. The player’s score should increase with each hit and decrease when the enemy hits the player. Also, the player should have a limited life, which when over signifies the end of the game.

DESCRIPTION The above objective was accomplished by using Python Programming Language. The player is ‘sitting’ in a spaceship and has to move through space by killing his enemies. The player has to take care of not only the ships, but the periodic meteors as well, varying in size. The player’s shield decreases every time he is hit by the enemy mob or the meteors. When the player’s shield falls below a certain percentage, the player is granted a ‘life’ which he can get by catching it. The player’s shield goes back to 100%.

DETAILS OF HARDWARE AND SOFTWARE The project is made entirely in Python using ‘tkinter’ module. No other special software is required. The only extra things needed are the images of the various objects used in the game. The game also has a soundtrack which loops throughout the game. Also, there are sounds for each bullet shot, mod killed and meteor hit.
