A complete Space Invaders game made using SDL2 in C++. Small project I've been working on in my spare time for fun.

- Player can destroy aliens in order to gain score
- When the player destroys all aliens, they move onto the next round and gain an additional life
- Can press the esc key to pause the game
- The game is virtually endless and can only end if either of the following conditions are met:
- If the player runs out of lives, the player gets taken to the game over screen
- If the aliens reach the ending line, the player gets taken to the game over screen
- Player can hide behind the blocks which take damage and can be destroyed upon hit
- The blocks will respawn on game reset
- The game over screen displays final score and why the player was brought to the game over screen
- Each type of alien is worth a different amount of score:
- Lower Alien: 10
- Middle Alien: 20
- Upper Alien: 30
- Boss Alien: ???
- Uses SDL2 and its other libraries: SDL2_image, SDL2_mixer, SDL2_ttf
- The levels geometry and starting objects are created using the Tiled application
- Levels created in Tiled are saved as a .tmx (.xml) file and read from the program
- The level files are read, decoded and decompressed with the help of other libraries: tinyXML, Base64, zlib
- The game uses a Finite State Machine to organise and swap between the states
- Currently, there are four states which can be changed too:
- PlayState
- MainMenuState
- PauseState
- GameOverState
- Game has audio support and has sound effects and a looping music track
- Game has TrueType font support
