Prism is a powerful and flexible Entity Component System (ECS) library designed for efficient game development in Roblox.
It enables a data-driven approach to managing entities and their behaviors.

Introduction

This is a rework of Celesta, my old ECS library, created a couple months ago. After having some problems with Celesta development, I stopped it and now I decided to open-source the new version of it with a new name -- Prism.

Usage

local world = require(shared.world)

local health = world.spawn()
local damaged = world.spawn()

local entity = world.spawn()
world.insert(entity, health, 100)
world.insert(entity, damaged, 10)

world.query(health, damaged) (function(entity)
    local health, damaged = world.get(entity, health, damaged)

    world.insert(entity, health, math.max(0, health - damaged)
    world.remove(entity, damaged)
end)
