# light_world.lua
|
|
|
|
This is the light modeling done by Priorblue [here](https://bitbucket.org/PriorBlue/love2d-light-and-shadow-engine),
|
|
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
|
|
|
|
```lua
|
|
local LightWorld = require "lib" --the path to where light_world is (in this repo "lib")
|
|
|
|
-- create light world
|
|
lightWorld = LightWorld({
|
|
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
|
|
```
|
|
