STD: Spaceship Tower Defense.

STD is a version in the space of the famous game Tower Defense.
There is a grid in which you can put spaceships to defense your land. Waves of asteroids come to attack you, so you need to install a big defense in order to keep the game going.

How it works

Each spaceship automatically shots from the left to right, but in case a well-known number of asteroids are on the same line behind the spaceship, this starts to shot from right to the left.

There are three types of spaceships:

• SNOW : very cheap white spaceship, very fast moving and shooting, but very weak
• GRASS : green spaceship with a cost, speed, and frequency of shooting in the average. Stronger than SNOW spaceship
• BLOOD: very expensive red spaceship, very slow moving and shooting but very hard to destroy. Very useful near the border of grid to create a defensive "wall"

Each time a spaceship is hit by an asteroid, if it is not a SNOW spaceship, it is turned in a lower type of spaceship, otherwise it is destroyed. For example a BLOOD spaceship can become a GRASS spaceship.

You can add only one spaceship per cell, if you can pay a well-known value with your score.

Asteroids can move only from right to left, and if they reach the left border score is decreased according on a well-known value.
Pay attention, because if you reach a negative score and you have not any other spaceships, you lose the match. Otherwise, until you have some spaceships alive, you can keep going with the game.
If you kill every asteroid in a wave, you can call a next wave.

Every wave has a bigger number of asteroids, so make sure you have a great defense!

Requirements

• Linux distribution
• GLUT is required for the GUI

GUI

A very basic GUI is used for the game. Thanks to Guillaume Perez for his GLUT based library.

Usage

Clone the repository:

$ git clone --recursive git@github.com:lukesmolo/STD.git

You can have a look at the Configuration.h file in order to set your favorite values
Compile the program:

$ make

If you modify Config.h file, please clean all and compile again:

$ make clean
$ make
