light_world.lua

This is the light modeling done by Priorblue here, only it has been largely refactored and edited to allow for scaling and proper translation.

*Supports love 11.2(master branch), 0.10.1(commit 414b9b74c0eb95bfb8b5e26a11caf2b32beccca0)

Installation

Copy and rename the lib folder into your project.

How to use

local LightWorld = require "lib" --the path to where light_world is (in this repo "lib")

--create light world
function love.load()
  lightWorld = LightWorld({
    ambient = {55/255,55/255,55/255},         --the general ambient light in the environment
  })
end

function love.update(dt)
  lightWorld:update(dt)
  lightWorld:setTranslation(x, y, scale)
end

function love.draw()
  love.graphics.push()
    love.graphics.translate(x, y)
    love.graphics.scale(scale)
    lightWorld:draw(function()
      -- do your stuff
    end)
  love.graphics.pop()
end

For more information please check out the wiki and see the examples directory to see how it is fully used. This project can be run with love to see the demonstrations in action.

Gamera & HUMP

There are example in the example directory how to use both of these with the library.
