New AutoGist Installer: https://gist.github.com/briarfox/5562489

The Installer is one file. Copy it and paste it over main in a newly created project named AutoGist. Then just run it twice! Thanks to @acp for the code.

AutoGist code - https://gist.github.com/briarfox/5525674

AutoGist 2.0 is here! First you will need to create a Github account @ http://www.github.com

-Open AutoGist and supply your username and password. These are not saved and only need to be used once. After you Authenticate it will save your Github token as a global.

-Exit and reload AutoGist

-You can now use AutoGist to pull full projects from a gist id. You Simply create a blank project, open AutoGist Enter the project name and the gist ID from the gist you want to pull.

-AutoGist can now create a single file that will install all tabs from a Gist. This makes it easy for people who do not have a Gist app. Simply Enter the Name of the Project and the gist id from it's gist. A new gist will be created with one file. That files is ran in place of main and will install the project all in separate tabs.

-You can comment out code that you do not want to appear in the Gist. use

--to comment out code do
--/*
code to comment out
--*/

This is how you include AutoGist into your project to backup.

To backup your projects you simply add this to your main file and include AutoGist in your project:
VERSION = your version number 
-- When this number changes it will update your Gist. 

BUILD = true/false 
--BUILD will create a separate gist for builds when set to true, version is ignored

In setup add:
AutoGist.setProjectInfo("YOUR CODEA PROJECT NAME","AUTHOR","DESCRIPTION",VERSION)
 -- VERSION should be the variable used in setting the version at the top.
AutoGist.backup()
 -- if you pass true in backup, your Version gist will be public.

Thats it! Future update will include Version tracking as a tab within Codea.

--# Main
-- SpritelyToDropbox

-- Use this function to perform your initial setup
function setup()
    print("Hello World!")
    aloader = SpritelyLoader()

    -- Change "YourImageNameHere" to the name of your image
    Name = "YourImageNameHere"
end

-- This function gets called once every frame
function draw()
    -- This sets a dark background color 
    background(40, 40, 50)

    -- This sets the line thickness
    strokeWidth(5)

    -- Do your drawing here
    createImage = loadstring( readProjectData(Name))
    anImage = createImage() 

    saveImage("Dropbox:"..Name, anImage)

    -- Quits program as soon as image is saved
    close()

end


--# SpritelyLoader
SpritelyLoader = class()

-- SpriteLoader 
-- ver. 1.0
-- moves data from global to project storage
-- ====================

-- This class takes data from global and dumps it into your project.
-- 
-- To use this class, create an instance in your project.
-- For example:  aloader = SpritelyLoader()
--
-- This call will read both keys and images from the global Spritely
-- storage and copy them into your project space. 
--
-- Once in the project data, load the saved string to 
-- an image using it's key.  For example:
--
-- createImage = loadstring( readProjectData("bob"))
-- anImage = createImage() 

-- To display your images, you'll need to load them into
-- a sprite. The command looks like this

-- sprite(anImage, 100, 100, 32, 32)

-- Good luck!

function SpritelyLoader:init()
    local keys, k, s
    if readGlobalData("SpritelyKeys") == nil then
        print("No Spritely data found.")
    else
        -- read global keys
        keys = readGlobalData("SpritelyKeys")
        saveProjectData("SpritelyKeys", keys)
        print("Moving...")
        for k in string.gmatch(keys,"([^,]+)") do
            print(k)
            s = readGlobalData(k)
            saveProjectData(k, s)
        end
        print("Move complete.")
    end

end

Just change Name = "YourImageNameHere" to your image name and after running the program sync your Dropbox from within Codea

Also note, if you want it to save to documents just change saveImage("Dropbox:") to saveImage("Documents:") The program is supposed to close as soon as the image is saved so do not be alarmed when it quits, the image should have been saved

Enjoy!

What are your thoughts - how could this problem be solved in an elegant way? My first idea would be to save all instances in a table and save this table to LocalData. Any other ideas? Any suggestions how to approach this?

Thanks to people who helped me learn to code in Codea. And all beta testers who helped improve this game a lot.

Thank you Simeon and TwoLivesLeft for Codea too :)

I use Codea Splash Screen in this game, hope it helps people know about Codea more.

Random photo code

Endless is a "roguelike" adventure game where you troop through randomly generated levels facing... well, endless numbers of monsters, discovering endless keys, opening endless chests, and descending endless staircases to the next level. Each level has a different sets of creatures, with difficulty that is always increasing. Likewise, weapons become more powerful and your character's abilities increase.

I've stripped the statistics down to a bare minimum (attack, defense, health) so at the moment there are no ranged weapons or magical attacks. I hope to work those in later. At the moment, all the graphics come from standard sprite packs. I'll improve on that with time, but don't really have plans to take this beyond the traditional 2D view..

Hopefully, I'll get an initial version out in the next week or so. Soon you too can discover a Balanced Sword of Unyielding Vorpalness and face off with a Deadly Whispering Spider.

Suggestions are welcome.

How can i insert in my game my own audio/sound using Codea?

Regards

Just want to share some free graphics for your projects in this thread :-) I think they might be useful for some of you anyway :)

All are free to use in commercial apps/games

Jack

You may have seen me in one of my other threads :) Didn't go as we'll as I thought it would, However I've decided to introduce myself,

My name is Jack, I'm from Ireland, I've been developing for 4 years, Mainly Lua, I'm a 100% Corona SDK developer, It's quite different to codea, Apart from the language itself of course! It's a very new experience developing on my iPad,

You can view my website here: http://thermo-apps.com

I also run a small online marketplace for developers for game assets like sounds, graphics and code: http://ThatDeveloperMarket.com

I look forward to integrating with the community here,

Thank you,

Goal is to create a class that allows command input and output from the screen so I do not have to have the parameters window open. Just can't figure out how to catch the errors.

I need help with mesh and ball movement. The ball have to move only on y-axis, so it looks like it is "not moving". And ground movement is based on how fast ball is moving on x-axis. As you can see on video it is too fast, i just can't find right formula. thanks

        ellipse(touch.x, touch.y, 100, 100)
    end
end

Quite often the same touch.id value appears again after only 2 or 3 touches. Is there a way to prevent this?

I'm building up gestures based on successive touch events and am using the touch.id as the unique identifier for the gesture. If a gesture doesn't exist with an id the same as any of the touches then create a new gesture. The problem is that if a touch.id is reused to quickly it tries to add it to the existing gesture rather than the new one.

        fill(255,0,0,255)
        ellipse(contact.position.x + 100,contact.position.y + 100,40)
end

And one more thing how can I find the unit vector along a certain a direction. I know the direction of vector v3 as v3=v1-v2 and I know v1 and v2. They are position vectors. I tried v3/math.abs(v3) but it only gives a positive or negative 1 which is right mathematically but in physics that's how we find the unit vector. So is there a way to find the unit vector along v3

I tried this but it seems pretty slow, that can't be right. I'm working on a side scroller and everything near the bottom should have a shader reflection...

Is my approach wrong?

Ship = class()



function Ship:init(x,y)

    self.x = x
    self.y = y
    self.m = mesh()
    self.m.texture=("SpaceCute:Rocketship")
    self.rIdx = self.m:addRect(0, 0, 0, 0)
    self.m:setRect(self.rIdx, 0, 0,64,64)

end

function Ship:draw()

pushMatrix()
translate(self.x, self.y)
    self.m.shader = nil
    -- Draw the mesh
        self.m:draw()
    translate(0, -64)



      self.m.shader = shader("Documents:Myripple")



    -- Configure out custom uniforms for the ripple shader
    self.m.shader.time = ElapsedTime
    self.m.shader.freq = 2

    self.m:draw()

    popMatrix()

end

function setup()
   myship={}
    for i=0 , 10 do
     myship[i] =  Ship(30+(i*64),250)
    end


end

-- This function gets called once every frame
function draw()
    -- This sets a dark background color 
    background(0, 0, 0, 255)


    for i=0 , 10 do
        myship[i]:draw()
    end

end

Any ideas?

Thanks

I'm getting "duplicate symbol" since the file surf.o is included twice. Any idea where the other reference is to it, and any idea how to solve. Maybe I need to put some time in compiling OpenCV myself instead of trying to use their precompiled version, but would be nice to not have to.

UPDATED to version 2 Now get your Github token inside the app http://twolivesleft.com/Codea/Talk/discussion/2744/autogist-v2-0-backup-your-projects-as-a-gist#Item_2

I had been using Gister by @acp. But I found that i rarely took the time to update my gists and when I did I would have to find the gist ID for my last gist. This resulted in creating multipal gists of my projects. I added on to @acp 's library to only update the gist when the version number changes. So just include this as a library and set the required info.@acp did all the work on this I just added version checking. So all credit is @acp 's :)

You are required to set some project info. This can be done manually or with AutoGist.setProjectInfo(). There are two fields that are required. "Project" = "Your Exact Project Name" and "Version" = "current version number"

Then you call AutoGist.backup() with no params it will create a new Gist id for the project and save it as private. It can take 2 parameters. The first can be true to make it a Public Gist and the second can be a Gist ID of a currently existing gist.

You will need to create a github account and get an Authentication key. I Save this key as local data so itcan not be accidently gisted for the world to see.

Make sure to grab all 3 files AutoGist on GitHub: https://gist.github.com/briarfox/5525674

GitHub token tutorial - https://help.github.com/articles/creating-an-oauth-token-for-command-line-use

function setup()  
AutoGist.setProjectInfo("AutoGist","Briarfox","Auto Gists your Project",VERSION) --sets Project Info
AutoGist.backup() -- Add this to make backups 
end

This is what I used to get and set the GitHub Token

--   curl https://api.github.com/authorizations \
--   --user "username" \
--   --data '{"scopes":["gist"],"note":"Codea Gister"}'

saveGlobalData("Auth_Gist_Token", PLACE_TOKEN_HERE) -- run this one in any projectthen delete it. you do not want to give this token out.
