Tiny Tutorial

There are loads of really useful You Tube tutorials out there for the various cross platform frameworks.

In fact there are probably too many, making it hard to know where to start.
The Corona SDK site offers a good selection:
http://www.coronalabs.com/resources/tutorials/ 
and
http://www.coronalabs.com/resources/videos/ 



I followed the basic Newbies Corona SDK tutorial this evening, and had a simple "game" running in an hour or so.


 

main.lua
display.setStatusBar(display.HiddenStatusBar)
local physics = require "physics"
physics.start()
physics.setGravity(0,0)

local background =  display.newImage("background.jpg")

local green = display.newImage("green.png")
green.x = 100
green.y = 100
physics.addBody(green, "dynamic")

local red = display.newImage("red.png")
red.x = 1000
red.y = 560
physics.addBody(red, "static")

local red2 = display.newImage("red.png")
red2.x = 800
red2.y = 500
physics.addBody(red2, "static")

function touchScreen(event)
    if event.phase == "began" then
        --event.x returns the x pos of the event, likewise event.y
        print (event.x)
        transition.to(green, {time=500, x=event.x, y=event.y})
    end
end

--[[ if runtime is replaced with specific object then that is the thing responded to
-- touch event has 3 phases:
began – dispatched when the user first touches the object.
moved – dispatched whenever user moves their finger, as they are touching.
ended & cancelled – dispatched whenever user lifts their finger or touch is cancelled for whatever reason.
--]]

Runtime:addEventListener("touch", touchScreen)

function moveRed()
    
    transition.to(red, {time=2000, x = math.random(80,880), y = math.random(60, 580), onComplete = moveRed})
    transition.to(red2, {time=2000, x = math.random(80,880), y = math.random(60, 580), onComplete = moveRed})
       
end
-- put call to function below function
moveRed()

function onCollision(event)
        --print ("Collision")
        green:removeSelf()
end

Runtime:addEventListener("collision", onCollision)

Spine again - animating game assets

Laura Tallarday gave a neat demo of how to build an animation in Spine on the CoronaGeek Hangout, so I had a bash at chopping up an image and animating it.
The plan is to add some more sophisticated animations to the new game "Duck sized horse".. but as was discussed in the show adding a whole bunch of spine animated objects might hammer a mobile device... and as the aim is to have 100 tiny duck sized horses, I'd best choose another approach for them.

anyway here's a swaying viking...




Using Corona SDK

Corona Architecture Overview
Diagram showing the Corona SDK architecture -source Walter Lua - CEO Corona The development process. I built the game "Ninja Dinosaurs vs Pirate Robots" in a series of 4 development sprints. I used a familiar game format, the "Infinite Runner" to guide the overall structure, and built the game using the Agile development methodology and Simplicity principle: "simplicity: write the simplest code to do the job, do not provide hooks in your code for ‘future needs" - this prevents scope creep. Studies by Jones (2009) have shown that Agile is most effective with small teams. Agile focuses on swift iterative cycles creating instances of working code, which are constantly reviewed and guided by the end users rather than a rigid commitment to a fixed system architecture. It values working code over heavy documentation, as might be encountered in a more traditional waterfall development approach.
