README
lue
==============
lue is a LÖVE library that allows you to manage your colors and display hue effects in your game.
![swotch][swotch]
See [HSL](https://en.wikipedia.org/wiki/HSL_and_HSV)
Setup
----------------
```lua
local lue = require "lue" --require the library
```
Usage
----------------
Set color
```lua
function love.load()
lue:setColor("my-color", {255, 255, 255})
end
```
Update lue
```lua
function love.update(dt)
lue:update(dt)
end
```
Get color
```lua
function love.draw()
love.graphics.setColor( lue:getColor("my-color") )
end
```
Color objects
----------------
You might also declare color objects instead of calling lue:setColor("colorname", color)
For instance,
```lua
function love.load()
myColor = lue:newColor():setColor({255, 255, 255}) --methods can be chained
end
function love.update(dt)
myColor:update(dt)
end
function love.draw()
love.graphics.setColor( myColor:getColor() )
end
```
Methods
----------------
Update lue
```lua
lue:update(dt)
```
Set color
```lua
lue:setColor("name", {colorTable}) --basic
lue:setColor("name", {
color = colorTable,
--[[ or ]]--
hue = hueTable -- {saturation, lightness, opacity, offset}
speed = number, --if provided, color with transition smoothly
})
--the same goes for myColor:setColor(...), just remove the "name" argument
```
Get color - if target == true, then the function will return the target color instead of the current color
```lua
lue:getColor("name", target)
myColor:getColor(target)
```
Get hue color - offset defaults to 0
```lua
lue:getHueColor(saturation, lightness, opacity, offset)
```
All values range from **0** to **255**.
Set/get the global color intensity of lue - useful for spontaneous color effects such as explosions
```lua
lue:setIntensity(intensity)
lue:getIntensity()
```
Set/get hue speed
```lua
lue:setSpeed(speed)
lue:getSpeed()
```
Get the current hue value (0-255)
```lua
lue:getHue()
```
