09:53 Manuel_CI: does anyone have an iOS device with a game with inapp purchases?
09:53 Manuel_CI: I need someone to check if they are working
09:53 Manuel_CI: not actually buy, just press on the button and see if the confirmation popup shows up
09:53 Lerg: yes
09:54 Lerg: works
09:54 Lerg: some older corona build

10:00 windreaper has left IRC (Ping timeout: 244 seconds)
10:04 Manuel_CI: well, regulars apps started working
10:04 PerturbedMollusk: anyone who has worked with director class?
10:04 Manuel_CI: but mine doesn't
10:04 Manuel_CI: what I find strange is that I picked an older project where inapp were working
10:04 Manuel_CI: built it again
10:04 Manuel_CI: and they don't work
10:04 Manuel_CI: there's something wrong with the build process
10:05 Hendrix000007 has left ()
10:06 Manuel_CI: is anyone able to build a corona app right now to test if inapp purchases are working?
10:07 alestane: I'm able to build, but I don't have any tests for IAP.
10:07 Manuel_CI: :/
10:08 Manuel_CI: I can't understand what might be working
10:08 Manuel_CI: what might be wrong actually
10:08 Manuel_CI: I'm sure that store.purchase() is being called
10:09 Manuel_CI: and if I'm disconnected from the internet, it goes to the inapp purchases listener and returns an error
10:09 Manuel_CI: if I got internet access, it doesn't even go into the listener
10:09 Manuel_CI: absolutely nothing happens
10:10 Manuel_CI: as if it trying to process the request indefinitely
10:10 Manuel_CI: And yesterday everything was working fine, and today it isn't
10:11 Manuel_CI: only explanation is that they changed somethign in the corona building process, in the servers
10:11 ricardo_CI has joined ([email protected])
10:13 Lerg: Or gremlins
10:14 PerturbedMollusk: anyone?
10:14 Manuel_CI: I grabbed a build from 2 weeks ago, that had inapp purchases working
10:14 NahirC: perturbedmollusk, i have
10:14 Manuel_CI: and they don't work now
10:14 Manuel_CI: which means it's not related to the building process
10:15 Manuel_CI: it must be a local problem
10:15 Manuel_CI: inapp purchases in portugal
10:15 Lerg: PerturbedMollusk: me too
10:15 Manuel_CI: maybe there's an issue with apple
10:15 Manuel_CI: I guess they joined wikipedia in the protest against SOPA or something
10:15 Manuel_CI: -_-
10:16 PerturbedMollusk: Lerg and NahirC, I have a different module for my background, another one for my cars (newImage objects and physics objects), another one for pedestrians....in his examples ricardo says to include all display objects in a displayGroup
10:16 Lerg: In Russia piracy would only increase due to sopa.
10:16 PerturbedMollusk: do I add them all seperately in their modules in the same group?
10:17 PerturbedMollusk: also, that means that the group for me would need to be global, right?
10:17 Lerg: PerturbedMollusk: you think about a bit wrong
10:17 Lerg: You can have many modules
10:18 Lerg: But only one file is displayed by director
10:18 PerturbedMollusk: yea, I have a level1 module
10:18 PerturbedMollusk: but everything is displayed using functions...
10:18 PerturbedMollusk: I cant do a newGroup:insert(somefunction) :(
10:19 PerturbedMollusk: has to be an oject
10:19 PerturbedMollusk: object*
10:19 Lerg: so in that one file you include what you need from modules for car and pedestrians and add them into one local group, which is in that one file.
10:19 Lerg: I have such modules separated
10:20 PerturbedMollusk: so in my level1 module, I would have a local newGroup and I would add eveything there...? that would mean my background and scorelabel and cars and pedestrians and all display objects should be global
10:20 Lerg: Some produce objects in one folder, other exclusively for director class in another folder
10:21 Lerg: You create them in level1 by calling specific module functions like newCar() or newPedestrian() and insert them into newGroup
10:22 PerturbedMollusk: insert the functions in the newGroup?
10:22 PerturbedMollusk: oh, you mean like
10:22 PerturbedMollusk: car:makeCars()
10:22 PerturbedMollusk: and then
10:22 PerturbedMollusk: newGroup:insert(newCar) ?
10:23 Lerg: local someCar = car:newCar()    newGroup:insert(someCar)
10:24 PerturbedMollusk: problem is, I have one function that creates all my cars in car.lua
10:24 enherit has joined ([email protected])
10:24 PerturbedMollusk: I dont just have a function that creates one car :P
10:24 Lerg: so what?
10:24 PerturbedMollusk: well
10:25 PerturbedMollusk: could car:newCar() be the method creating all the cars? cause then someCar would be all the cars
10:25 PerturbedMollusk: or do I do it to newCar(), the one producing each car seperately?
10:25 Lerg: for i, someCar in ipairs(car:makeCars()) do newGroup:insert(someCar) end
10:25 Manuel_CI: the important thing is that the function returns a display object
10:25 Manuel_CI: it can be a group with all cars in it
10:26 enherit_ has joined ([email protected])
10:26 PerturbedMollusk: ok, now I'm confused...let me just send you a pastebin with snippets of my code as reference...
10:26 PerturbedMollusk: so I understand it...
10:26 PerturbedMollusk: is that ok?
10:29 Lerg: ok
10:38 PerturbedMollusk: ok
10:38 PerturbedMollusk: this is my level1
10:38 PerturbedMollusk: http://pastebin.com/yLPdcM0P
10:38 PerturbedMollusk: my setup.lua http://pastebin.com/DZ6GzcYY
10:39 PerturbedMollusk: and my car.lua http://pastebin.com/1yQQDXSJ
10:39 PerturbedMollusk: i think they should be enough
10:39 PerturbedMollusk: I've taken irrelevant methods and values out
10:39 PerturbedMollusk: to keep them short
10:41 PerturbedMollusk: as you can see, in car.lua, I have the function new which creates a new car, makeCars which gives new the arguements it needs and adds each car to the physics engine and makes it a sensor and everything else it needs
10:41 Lerg: oh
10:41 PerturbedMollusk: and spawnCars which is called every so often to actually spawn the cars
10:41 Lerg: you really have designed for intensive use of globals
10:41 PerturbedMollusk: well, I went for oop, everything in its module
10:42 PerturbedMollusk: I dont really have that many globals i dont think
10:42 Lerg: in terms of OOP - poor incapsulation or isolation is it...
10:43 Lerg: I guess it would be really easier to you just to use global group
10:43 PerturbedMollusk: would it be so bad to use global group, really?

10:44 Lerg: prone to some errors
10:44 Lerg: but it's not prohibited
10:44 PerturbedMollusk: hmm
10:44 PerturbedMollusk: what did I do wrong?
10:44 PerturbedMollusk: as far as oop goes
10:46 tsivertsen_ has joined ([email protected])
10:46 Lerg: first of all moule(..., package.seeall) is not good
10:46 PerturbedMollusk: it isnt? in every tutorial i see its there...why is it not good?
10:47 Lerg: second it's better to have modules like director, physics and those which are you using everywhere as globals in main.lua
10:48 tsivertsen has left IRC (Ping timeout: 240 seconds)
10:48 Lerg: third, car and ped modules should provide function to create stuff but they should not rely on anything from outside, like global localGroup
10:49 Lerg: instead those functions should return display objects which are later to be inserted somewhere
10:49 PerturbedMollusk: well, they didnt rely on anything outisde before I decided to include the director class in my game
10:49 PerturbedMollusk: but now it seems they need to
10:50 Lerg: it would help to understand by renaming car into carFactory for example
10:50 tsivertsen_ has left IRC (Ping timeout: 240 seconds)
10:52 Lerg: Not all tutorials are good enough...
10:52 PerturbedMollusk: ok, so one at a time...
10:52 PerturbedMollusk: why is module seeall not good?
10:52 PerturbedMollusk: what does it acutally do?
10:52 Lerg: it's ambiguous
10:54 alestane: If you are going to use module (which is no longer popular), I recommend local "_G = _G; module(...)" over "module(..., package.seeall)"
10:55 PerturbedMollusk: what do they do?

11:15 Lerg: hi
11:15 ricardo_CI: hello!
11:16 stomith: o/
11:16 PerturbedMollusk: hendrix, do you know what module(...,package.seeall) does, and why local _G = _G;module(...) is better? (and also what the latter does too?)
11:16 Boydy has joined ([email protected])
11:16 PerturbedMollusk: I think the ones I first asked are too busy to answer :P
11:16 PerturbedMollusk: or havent noticed
11:17 Hendrix000007_: or explained it too many times ;D
11:17 Hendrix000007_: hihi
11:17 PerturbedMollusk: I'm sure they'd say so if that was the case
11:17 Hendrix000007_: Lerg explained this to me some days ago
11:17 PerturbedMollusk: and tell me where to find the answer
11:18 Hendrix000007_: Ill try ...
11:19 Lerg: yeah, I am too busy atm
11:19 Hendrix000007_: First of all a important thing is that the module see all thing are deprecated function that will be left dead some time in the future
11:20 alestane: Going slightly crazy trying to sort out web display, sorry.
11:20 alestane: Also, I generally discourage using module at all.
11:20 Hendrix000007_: thats one of the reasons why Im goin over to classes or external method librarys
11:22 Hendrix000007_: and call them like local car = require ("car") --assume u got a class file: car.lua
11:23 PerturbedMollusk: yes, I do. but what does local car = require("car") have to do with module seeall
11:23 PerturbedMollusk: ?
11:23 PerturbedMollusk: btw I have already done that local car = require ("car") thing
11:24 Hendrix000007_: and then call the instance of the method -(the object), like this: car:addToMotor("highGear", 100)
11:24 PerturbedMollusk: yea, thats what i do
11:26 Hendrix000007_: local car = require("car") is the direct call to a method and  is instead of package see all stuff
11:26 Hendrix000007_: actually u don't have any of that stuff in the top of the class file
11:27 PerturbedMollusk: which one?
11:27 Hendrix000007_: i.e. car.lua
11:28 PerturbedMollusk: I do
11:28 PerturbedMollusk: physics, setup and ped
11:28 PerturbedMollusk: lines 13-15
11:29 Hendrix000007_: car.lua could start w : _car = {} --[[and heres all the props and functions and so on--]] return _Car
11:29 Hendrix000007_: right Lerg?
11:30 Hendrix000007_: sorry, return _car!
11:30 Lerg: if only one car - yes, but he needs many cars
11:31 Hendrix000007_: ahh yes what a coincidence! it was an example out of the blue but mollusk working w that carspawning right?
11:31 Lerg: right
11:31 PerturbedMollusk: yes
11:31 Hendrix000007_: lol
11:31 PerturbedMollusk: :P
11:32 Hendrix000007_: when I started to understand the method stuff I feel like takin a big leap in the right dir, feels much cleaner way of coin it
11:33 Hendrix000007_: coin==doing
11:33 PerturbedMollusk: well, i can worry about module later, for now I just need someone to explain to me how I would use director class according to the modules I have
11:33 PerturbedMollusk: that would be a massive help
11:34 Hendrix000007_: so whats wrong Mollusk¿
11:34 alestane: Um. Is there any simple way to copy a file from the Resources directory to the Documents directory in Corona, or do I have to open it and write all the lines to a new file?
11:35 Marble68: read and write, alestane- that's the only way I know how to do it.
11:35 alestane: I could really wish they'd included LuaFS in Corona.
11:35 Marble68: there's a copy file code snippet on the website
11:35 PerturbedMollusk: I dont know how to use the director class, Hendrix. Let me explain. In the director class page, in Corona site, the creator has a sample program
11:36 PerturbedMollusk: and in his screen1 (my level1) he creates one of each thing (buttons, backgrounds etc) in the same module (screen1) and inserts them in his newGroup
11:36 PerturbedMollusk: problem is, I have my stuff in their own modules
11:36 Manuel_CI: alestane: you can use os.execute("mv file1 file2")
11:36 PerturbedMollusk: one for background, one for ped one for cars
11:37 Manuel_CI: though there a little problem! It doesn't work on device, only simulator :P
11:37 alestane: That's not a *little* problem.
11:37 Manuel_CI: I know
11:37 Manuel_CI: lol
11:37 alestane: I don't think iOS lets you use a shell. I'd be shocked if they did.
11:37 PerturbedMollusk: and I have a method that creates a car for example, but then I have another one that creates many cars
11:37 PerturbedMollusk: giving car.new the parameters it needs (code is here http://pastebin.com/1yQQDXSJ )
11:38 PerturbedMollusk: so how do I include my objects in the newGroup?
11:38 PerturbedMollusk: if they are in different modules, and local?
11:38 Manuel_CI: on jailbroken devices you can..
11:38 Manuel_CI: but not like it matters here anyway
11:38 Manuel_CI: lol
11:39 Hendrix000007_: Mollusk: I think U just call them in the newGroup() but theres an issue:
11:39 rob9988 has joined ([email protected])
11:40 Hendrix000007_: you have to think of the locals inside functions in your module
11:40 PerturbedMollusk: like what?
11:41 PerturbedMollusk: spawnX and spawnY?
11:41 Hendrix000007_: they have to be 'local globals' to bee seen in other scripts that calls them
11:41 PerturbedMollusk: well, if they are local in the code I have posted, no other modules need to see them
11:41 Hendrix000007_: bee~= humbleBee lol
11:41 PerturbedMollusk: so why would they need to see them now?
11:42 Hendrix000007_: but if use join to return values from a function you have to declare it outside the function in the modulefile
11:42 PerturbedMollusk: if I use join? what's join?
11:42 Hendrix000007_: omg I'm a real bad one on the keyb 2 day!!
11:43 Hendrix000007_: I mean if you want to return a value
11:43 treser2 has joined ([email protected])
11:44 PerturbedMollusk: only thing I'm returning is newCar and newPed and they are global already
11:44 Hendrix000007_: ok then I see
11:44 PerturbedMollusk: anyway, I have to go now it seems, I'll have another go at this tomorrow, probably post a question in the forums as well...
11:44 PerturbedMollusk: hopefully youll be here tomorrow :P

11:45 Hendrix000007_: yes we do
11:46 Hendrix000007_: can someone help me with a retina [@2] q?
11:47 treser has left IRC (Ping timeout: 240 seconds)
11:48 ricardo_CI: @Hendrix000007 don't you get some notification when someone sends you a private message? ;)
11:48 kristiannn: whats the question Hendrix?
11:48 Hendrix000007_: I want to use display.newImageRect on my button : local buttonLeft = ui.newButton{default = "buttonAction.png"}
11:48 Hendrix000007_: so I can use scaling function
11:49 Hendrix000007_: the ratio stuff we talked about in here earlier
11:49 Hendrix000007_: iphone4 to iPad with diff ratio
11:49 kristiannn: as far as I know you would have to change the ui function
11:50 Hendrix000007_: I want to have a HD version of my buttons in the "hud"
11:50 Hendrix000007_: to use for iPad)retina
11:50 Manuel_CI: whats that ui?
11:50 Manuel_CI: is it a module of yours?
11:51 Hendrix000007_: a class for buttons and such
11:51 Hendrix000007_: like a native Corona lib
11:51 kristiannn: check the ui file for display.newImage and change it to display.newImageRect (be sure to add image sizes as parameters)
11:51 Manuel_CI: ye, you have to edit that ui module.. go to the newButton function
11:51 kristiannn: and you need to change the images of course
11:52 Manuel_CI: and change to newImageRect
11:52 Hendrix000007_: thanx I ll do that you're gold guys!
11:52 Manuel_CI: also, you will need to be able to provide the size parameters to newButton
11:52 kristiannn: also check for newText and change it to newRetinaText
11:53 Hendrix000007_: but isn't there a issue regarding the retina text?
11:53 Hendrix000007_: like double size /2
11:53 Hendrix000007_: or something when ref point set to center?
11:53 kristiannn: I think that was before they added newRetinaText
11:53 kristiannn: just try ;)
11:53 Hendrix000007_: ok, ill try
11:54 alestane: newRetinaText just produces a text object and sets the size and scale on it AFAIK.
11:54 alestane: It's a convenience function, but nothing you can't do yourself.
11:56 treser2 has left IRC (Read error: Connection reset by peer)
11:56 treser2 has joined ([email protected])
11:56 Hendrix000007_: alestane: do you use it?
11:57 alestane: I don't, because it's only even useful if you're using automatic content scaling, which I don't.
11:57 Hendrix000007_: u use true?
11:58 Hendrix000007_: has anyone tested the stretch instead of letterbox?
11:58 Marble68: I don't use Corona's scaling
11:58 Marble68: I do all my own
11:59 Marble68: it's ugly, and cumbersome - but it works better
11:59 Hendrix000007_: Im not there yet ;D

11:59 enherit has left IRC (Quit: leaving)
11:59 Hendrix000007_: but some day…
11:59 Marble68: (unless you use native UI elements, then you *must* use scaling) - because there are bugs with those on Retina displays. (unless they've fixed the bugs)
11:59 frankbro|sleep is now known as frankbro
12:00 Manuel_CI: I find it surprising that there is people not using the automatic content scaling
12:00 Manuel_CI: :o
12:00 Manuel_CI: it's like one of the best things ever
12:01 Hendrix000007_: like the @2 stuff?
12:01 Manuel_CI: yes

12:06 Lerg: Magic blur I would say
12:09 Hendrix000007_: yes and its relative old too
12:09 Hendrix000007_: I remember when it came
12:27 kristiannn: when I create 4 balls with a createBalls() function, how can I then check their velocity with getLinearVelocity?
12:33 Manuel_CI: your createBalls() function has to return the physical body that it created
12:33 Manuel_CI: and in the code where you call for createBalls, you have to save them smewhere
12:33 Manuel_CI: so you can later call getLineaVelocity on them
12:40 Hendrix000007_: like getLinearVelocity(self) form the object?
12:43 Manuel_CI: Anyone knows how to create a function with a variable number or arguments? like the print function, where u can print(arg1,arg2,arg3,...)

12:47 lKinx: Math isn't that hard for me.
12:47 lKinx: Luckily
12:47 Manuel_CI: print(arg,...)
12:47 Manuel_CI: and then after working with arg, call print on (...) again?
12:48 Lerg: let me refresh my old memory
12:48 Manuel_CI: lol
12:48 Lerg: http://www.lua.org/pil/5.2.html
12:49 lKinx: Later today I have to shrink my visuals and change the layout code.
12:49 Lerg: ipairs on arg should use you, but not to define the literal arg argument.
12:49 lKinx: Won't be fun
12:50 Manuel_CI: I was thinking a bit functionaly

13:16 alestane: I suspect the easiest workaround will be to insert the time myself.
13:18 alestane: Or maybe use the 'localtime' specifier.
13:20 alestane: Yes, that seems to have done the trick.

13:28 Manuel_CI: what happens is
