Gun Turret

Borne of a desire to see if I could wrangle Unity’s then brand-new ECS library into some dramatic large-scale interactive battle scene I set out to see about building a gun turret.

Issues with parenting game objects to each other within ECS, and with collider coordinates being broken for child objects put a damper on my excitement, but I did end up building a basic understanding of the framework. I also had to wrestle with a lot of tricksy trigonometry, coordinate conversions and PID controller logic to work out how to smoothly rotate the turret within gimbal-constrained axis. So much maths.

In the end I decided to drop the ECS aspect and re-implemented the turret in a more traditional Unity way; I wanted to be able to progress with my game design ideas rather than battle with buggy beta software!
