NEAT Bullets – 2D Weapon Evolution System

NEAT Bullets is a tool that allows you to create weapons with unique bullet patterns. Trajectory of projectiles is determined by a set of parameters and an artificial neural network generated using the NEAT algorithm.

WebGL Demo • Documentation

Four scenes included:

• Weapon Evolution scene where you can evolve and save weapons

• Weapon Demo scene where you can test 80 different pre-configured weapons and see their force fields

• Shadow Survival scene demonstrates how this system can be incorporated into gameplay. Characters' animations and tilemap from this scene are NOT included!

• Space Shooter scene is a simple space shooter game, where the enemies have randomly generated weapons

Technical details

• The asset was created using the URP template, but it works fine with any other rendering pipeline. However, you may need to add any missing materials to the sprite renderers.

• On each projectile, a force is applied every fixed update. For this reason the system is not very performant. You can test performance in Weapon Demo scene on weapon #69. Its projectiles have an unlimited lifespan, so you can see how the FPS changes depending on the number of projectiles.

• Projectile pooling is not implemented.
