Toony Flash game prototype ported to iPhone using Corona SDK

April 17, 2012 • Game design, iPhone, Users contributions by Emanuele Feronato • 3 Comments

Yesterday I blogged about Toony Flash game and I said it would be interesting to port the game to mobile devices.

Some hours later, Jason Ian Green from PodWork sent me the Corona SDK version of the prototype I made with AS3.

This is what you’ll get:

and this is main.lua file, with the complete script:

-----------------------------------------------------------------------------------------

-- main.lua

-----------------------------------------------------------------------------------------

local toonyVector = {}
local toRemove = {}
local interface = display.newGroup()
local toonyTypes = {"square.png", "circle.png", "hexagon.png", "flower.png"}

local currentObj
local originX
local originY

local score = 0

local function onTouch(event) 
	if event.phase == "began" then
		--print("began")
		currentObj = event.target
		originX = currentObj.x
		originY = currentObj.y
	end
	if event.phase == "moved" then
		--print("moved")
		currentObj.x = event.x
		currentObj.y = event.y
	end
	if event.phase == "ended" or event.phase == "cancelled" then
		--print("ednded")
		for n = 1, #toonyVector, 1 do
			local diffx = currentObj.x - toonyVector[n].x
			local diffy = currentObj.y - toonyVector[n].y
			if currentObj.id == toonyVector[n].id then
				if math.abs(diffx) < 20 and math.abs(diffy) < 20 then
					toonyVector[n].alpha = 1.0
				end
			end
		end
		currentObj.x = originX
		currentObj.y = originY

end
end

local function go(event) 
	for i = 1, #toonyVector, 1 do
		toonyVector[i].y = toonyVector[i].y + 1
		if toonyVector[i].y > 260 then
			if toonyVector[i].alpha == 1.0 then
				score = score + 1
				print(score)
			end
			toonyVector[i]:removeSelf()
			table.insert(toRemove,i)
		end
	end
	for j = #toRemove, 1, -1 do
		table.remove(toonyVector,j)
	end
	toRemove={}
end

local function newToony(event) 
	local rand = math.random(4)
	local newToon = display.newImage( toonyTypes[rand] )
	newToon.x = math.random(400) + 25
	newToon.y = 25
	newToon.id = rand
	newToon.alpha = 0.5
	table.insert(toonyVector,newToon)
end

local function main()
		local tSquare = display.newImage( toonyTypes[1] )
		tSquare.x=100
		tSquare.y=295
		tSquare.id = 1
		tSquare:addEventListener( "touch", onTouch )
		interface:insert(tSquare)

local tCircle = display.newImage( toonyTypes[2] )
		tCircle.x=200;
		tCircle.y=295;
		tCircle.id = 2
		tCircle:addEventListener( "touch", onTouch )
		interface:insert(tCircle)

local tHexagon = display.newImage( toonyTypes[3] )
		tHexagon.x=300;
		tHexagon.y=295;
		tHexagon.id = 3
		tHexagon:addEventListener( "touch", onTouch )
		interface:insert(tHexagon)

local tFlower = display.newImage( toonyTypes[4] )
		tFlower.x=400;
		tFlower.y=295;
		tFlower.id = 4
		tFlower:addEventListener( "touch", onTouch )
		interface:insert(tFlower)

Runtime:addEventListener( "enterFrame", go )
		timer.performWithDelay( 2000, newToony, 0 )
end

You can also download the entire project to compile it on your own on Corona SDK.

If anyone wants to continue with the porting, I will be happy to host it on the blog.

Glad to help out, you have given so many great tutorials, I thought it was time to give something back. To anyone who wants to use this code, beware that I didn’t have time to perfect the drag and drop functionality and I think objects can get left behind if you move to fast. There are probably a whole bunch of great drag and drop corona tutorials and classes out there so shouldn’t be a problem.

Hey, this is nice!

You’ll write tutorials about Corona?

Thanks.
