How to make a weapon customization system

Hello, how can I create a customization system that with accessories that influences the behavior of the weapon such as recoil, bullet speed, lethality and player speed, any idea of ​​how I should start

With player speed, you really need to plan ahead to keep it synched to your animations.

For bullet spread, here’s how it’s done; remember that you’re spawning projectiles from an socket.

Lethality is tied to the code that you’ve written for the projectile itself.

And as far as modular weapon upgrades goes, I think that this should work.

thank you very much you have been a great help
