My first Gideros game: Guess a number, all text

Magnusviri

Ok, this is litterally just an experiment. I was seeing in how few lines I could write this. Turns out it takes a lot of lines because I have to emulate a console. I should probably just create a real GUI. I'm hesitant to post such messy code but I'm just going to take the plunge.

I'm curious what others think and if anyone has suggestions how I could make it simpler so that I could teach it to people who have never programmed before.

Console = Core.class(Sprite) function Console:init() self.xbeg = 0 self.ybeg = 0 self.x = 0 self.y = 0 self.xinc = 7 self.yinc = 12 end function Console:incrementY(increment) self.y = self.y + increment if self.y > 320 then self:setY(self:getY()-increment) end self.x = self.xbeg end function Console:printTF(message) local textfield = TextField.new(nil, message) textfield:setPosition(self.x, self.y) self:addChild(textfield) return textfield end function Console:printN(message) if message ~= "" then local textfield = self:printTF(message) end self:incrementY(self.yinc) return textfield end function Console:print(message) local textfield = self:printTF(message) self.x = self.x+self.xinc*string.len(message) return textfield end function Console:printB(message) local textfield = TextField.new(nil, message) local paddingY = 14 local paddingX = 7 local width = textfield:getWidth()+paddingX*2 local height = textfield:getHeight()+paddingY*2   local x = self.x local y = self.y+paddingY   self.x = self.x+width+paddingX/2 local shape = Shape.new() shape:setFillStyle(Shape.SOLID, 0xffff00, 1.0) shape:beginPath(Shape.NON_ZERO) shape:moveTo(0, 0) shape:lineTo(0, -height) shape:lineTo(width, -height) shape:lineTo(width, 0) shape:lineTo(0, 0) shape:closePath() shape:endPath() shape:setPosition(x, y) textfield:setPosition(paddingX, -paddingY) shape:addChild(textfield) self:addChild(shape) return shape end   console = Console.new() stage:addChild(console) console:setPosition(3, 10)   math.randomseed( os.time() )   function makeAGuess(textfield, event) if textfield:hitTestPoint(event.x, event.y) then guess = textfield.number guessesTaken = guessesTaken + 1   if guess == secretNumber then console:printN(textfield.number.." is right! You took this many guesses: "..guessesTaken..".") console:printN("Let's play again.") startGame() else if guess > secretNumber then console:printN(textfield.number.." is too high.") elseif guess < secretNumber then console:printN(textfield.number.." is too low.") end if guessesTaken > 5 then console:printN("You took too long. The number was "..secretNumber) console:printN("Let's play again.") startGame() end   end   event:stopPropagation() end end   function startGame() secretNumber = math.random( 20 ) console:printN("I am thinking of a number between 1 and 20.") console:printN("") local button for ii=1,20,1 do button = console:printB(ii) button.number = ii button:addEventListener(Event.MOUSE_DOWN, makeAGuess, button) end console:incrementY(button:getHeight()) guessesTaken = 0 end   startGame()

Good one. http://builtwithgideros.com/ ?

Hmm,
I'd created one text field showing number and two arrows to increase it and decrese it and a button to take a guess.

And why do you need to save all previous game information on screen?

But yeah, this kind of interaction would probably require some code

Ok I know I made it really weird. I'm coding on my iPad using Textastic, uploading to Dropbox, and I've customized my Gideros exported project so that it downloads the file from Dropbox and then runs it. The problem is that there is absolutely no debugging and so when I have an error it just blinks off. I found I needed to print out a lot of information like in a console so I made something that will do that. I am probably going to find some way to shake the phone or some secret gesture that will get the console to show and then it will only be for my eyes.

I've already started to make a semi gui with shapes.

Another reason I don't have any graphics is because I haven't customized my Gideros app on my phone with anything but downloading one lua file. I hope to eventually have it download a whole project, kinda like what Gideros Player does with a desktop computer. Don't ask me why I don't program when I'm in front of my laptop/desktop. I just do different things when I'm in front of them and I do Gideros stuff when I've got my iPad in front of me.

@magnusviri Would it be possible for you to share the project you use to download and execute lua main from Dropbox? I am also interested to develop on my iPad at the office

Thanks!

@grotly here is a version. Pretty rough. You have to set the URL in the Settings App.
