Object.lua

Object.lua is a simple library to create objects

Creating an object

To create a object, you can call the constructor

object.new(_x, _y)

The x and y parameters are optional.

here a simple example

function love.load()
    object = require 'object'

    player = object.new()   -- create a new Object
    player:loadGraphic("resources/images/player.png")   -- load the image to object
end

function love.draw()
    player:draw()   -- draw the object
end

Object.lua also support animation with spritesheet and a map file.

function love.load()
    object = require 'object'

    player = object.new()   -- create a new object
    player:loadSparrow("resources/images/player")   -- load the spritesheet and the map file (it need be with the same name  example : player.png, player.json) [check the resources files to see the player]
    player:registerAnimation("walk_down", {1, 2, 1, 3})   -- setup the animation based on quad indexes
    player:registerAnimation("walk_up", {7, 8, 7, 9})  
    player:registerAnimation("walk_dir", {4, 5, 4, 6}) 
    player:setAnimation("walk_dir", 5, true)
end

function love.draw()
    player:draw()
end

function love.update(elapsed)
    player:update(elapsed)
end

you can also control how the object will be displayed with some variables.

function love.load()
    object = require 'object'

    player = object.new()   -- create a new Object
    player:loadGraphic("resources/images/player.png")   -- load the image to object

    -- set the object position --
    player.x = love.graphics.getWidth()
    player.y = love.graphics.getHeight()

    -- or you can get the easy way --
    player:centerScreen()

    -- and also center the origin point --
    player:centerOrigin()

    -- and flip it horizontally or vertically --
    player:flipX(true)  -- now the object is flipped on X
    player:flipY(false) -- and here the object is on normal direction
end

Object.lua also have built-in functions to hitboxes, so you don't need to setup any hitbox. When you create a object a hitbox is automatically created.

object:updateHitbox()
