RayneEngine

RayneEngine is a small custom 2D game engine built with SFML.
It’s a portfolio project created as part of my training as a Game Engineer — focused on learning, experimenting, and exploring engine architecture in C++.

This engine is not meant to become a large-scale framework, but rather a compact, understandable system that demonstrates how core engine components work together.

Development Status

RayneEngine is still in early development.
Most systems are experimental and will change frequently as I refine the structure and design.

The following Code...

local speed = 100
local amplitude = 100
local timer = 0
local startY = nil

function OnCreate()
    print("Lua: Started Player Script")
end

function OnUpdate(dt)
    local pos = GetTransform(self)
    timer = timer + dt

    if startY == nil then
        startY = pos.y
    end

    local newX = pos.x + speed * dt
    local newY = startY + MathR.Sin(timer * 1) * amplitude

    SetPosition(self, newX, newY)

    print("Player is now on Position: " .. pos.x .. ", " .. pos.y)
end

results in the following pictures...

NOTE: This is experimental and needs further development to be completely functional.

Planned / Early Features

• Core Engine Structure

  • Main loop with delta time
  • Modular design (rendering, input, scene management)
  • Basic ECS (Entity Component System)

• Rendering

  • SFML-based 2D renderer
  • Sprite and texture handling
  • Basic camera system

• Input

  • Keyboard and mouse input via SFML events, but planned to be in Lua events

• Scene Management

  • Early prototype of an entity and scene system
  • Simple resource loader - PLANNED

• Utility Layer

  • Logging system - PLANNED
  • Math helpers (vectors, transforms, etc.) with Lua integration

• Future Goals

  • Physics prototype
  • Simple in-engine debugging tools
