Drone Shooter is a simple FPS game created with OpenGL.
The goal is to shoot as many drones as you can before they kill you. There are four maps to choose from: forest, desert, snow and night.

Drone Shooter was created using just OpenGL, no game engine. It's purely done for fun and learning purposes.
The inspiration for this project was this OpenGL FPS game.

Some of the code is based on code from the learnopengl tutorial by Joey de Vries, such as shader.h, mesh.h and model.h.

The game objects (models, sounds, font and textures) were all downloaded for free from the internet.
I used sites like free3d, soundjay and freebpr. Unfortunately I did not save the exact links to the used objects.

To implement collision detection between the player’s bullet and enemy and between the enemy’s laser beam and player this site was a great resource. Box.h and ray.h are based on code from that site.

For adding soundeffects, rendering text and loading 3D models the libraries miniaudio, freetype and assimp were used.

There is no actual player character, it’s just a gun. The direction of the bullet is the same as the front vector of the player, which makes aiming easy. The player’s bounding box looks as follows:

The enemy is a drone that can shoot laser beams. Its aim is not perfect; some randomness is added when calculating the direction of the laser beam, otherwise every shot would lead to a decrease in the player’s health.
The bounding box of the enemy does not cover the whole drone, as can be seen in the image below. It may look weird but it’s not a problem at all. The bounding box is still big enough so that hitting the drone is quite easy, even when standing far away.

• CMake (version 3.5 or higher)
• C++ Compiler with C++17 support
• Git

1. Clone this Repository

   git clone https://github.com/EtoileScintillante/opengl-drone-shooter.git
   cd opengl-drone-shooter

2. Build the Game

   mkdir build
   cd build
   cmake ..
   cmake --build .

3. Run the Game (executable not in build dir)

   ./Drone-Shooter

During the development I regularly uploaded videos to YouTube to keep track of the progress I made.
