Asteroids
About the Project
This game was made as a part of our Computer Technology Assignment, It was my first time dwelling into Rust and SDL as well as Data Oriented Programming. It was definitely a very fresh learning expereience. I used specs package to implement ECS in the project.
Movement
After the Player's current rotation is set we set an impulse value in the direction its facing. When updating the movement of the ship we first decrease its current speed by a predefined friction value, add the recalculated impulse and normalize it to the max speed of the ship. Once we have calculated the speed of the ship we make the actual change in the player position multiplied by the deltaTime of the frame. All this gives a very smooth effect to the ship's movements and keeps it frame independent.
Entity Component System
ECS was implemented thanks to the specs package. This allowed me to define components and then register entities who act as a culmination of their components. We could also find entities in the system easily with the help of their component make up using rust. We then proceed to implement systems which take in consideration the entities it needs to act on and makes the necessary actions.
Collision Systems
The window is dynamically divided into multiple sections, All the collisions between the ship, asteroids and missiles are only checked within the same section. the section of the entities are updated as they move between them. The collisions are further calculated by comparing the squared distance between the entities.
