Tim Anema f56ef4a197 got the start of a shader that will do normal shading and shine at the same time, I will throw in a shadow map there too and it will do it all in one pass		2014-11-29 14:52:05 -05:00

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.

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
lightWorld = LightWorld({
  drawBackground = drawBackground, --the callback to use for drawing the background
  drawForeground = drawForeground, --the callback to use for drawing the foreground
  ambient = {55,55,55},         --the general ambient light in the environment
})

function love.draw()
  love.graphics.push()
    love.graphics.translate(x, y)
    love.graphics.scale(scale)
    lightWorld:draw(x,y,scale)
  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.
