I made a LuaAPI in a month and I made it like an OS, it has graphics, sound, networking, OS controling and more. Its not ready and I dont know If I will ever release it becouse ( I think ) no one will like it, but anyways I'll post some screenshots!

Screenshots

Here is a BIT of code written in this API

Features you ask? Here:

Costum launchers/startups
Desktop manipulation
Auto Icon creation
Code Everything IN Lua!
Easy to learn API.
Graphics
Sound
Dll file including

Still I don't know if anyone is interested, BUT if someone is I will post and insert the link where you can download.

Or you can learn it easier.

Or you will know what the code does in your head, then code it in the engine?

Soo many options I get in my head when someone says transparent.

This is amazing! You should be proud. Please continue working on this. Building it for raspbian linux would be really great. Then a raspberry pi computer could load your OS at startup… On top on linux?
Also, it seems everyone want you to develop every feature in the voting polls. Congrats on those results!

Yeah, you get it more or less. My raspberry pi has a config file that lets you set an app to run at startup, before loading the GUI. "Scratch" is the program that it boots into right now, but simply pointing it at your (linux port) LoveOS would mean it could boot straight into your app, and seem like an OS, even though linux would be running.
You would want full screen 720p resolution, so it was not in a window at startup.

On a different subject, I was prompted to install some 3rd party software when opening your app: "direct play" was the software it wanted. I said skip it, and it still worked well. Maybe you could remove the dependency, or trigger, on direct play. I also had some text display issues: the text was crushed a little, so it distorted the font a bit.

Thanks!

Thanks for the reports, direct play is needed for some stuff to do I left it so that people can install it if they want to run the OS better. And the font is temporary, I'll make my own font using Lua.

You really need to remove that dependency on DirectPlay. The last system to fully support it was Windows XP and support was completely dropped in 2007… what do you need it for anyway? Since you seem to be restricting the program to Windows, why not use WinSock?

I also can't seem to be able to use the dll library. Apparently, it's nil. But do you really want a dll library? It'd give you full access to Win32, which isn't the safest thing to do…
Take this piece of code for example:


local mciSendString = dll.add("winmm.dll", "mciSendStringA", dll.cdecl, dll.aInteger, dll.aString, dll.aString, dll.aInteger, dll.aInteger)
dll.call(mciSendString, "set CDaudio door open", "", 0, 0)
dll.free("winmm.dll")

This code will open the computer's disk drive (or would, if the dll lib worked). Not very malicious, but it demonstrates just how much power you're giving your programs.

While I really wouldn't call this an operating system, you can really tell that you put a lot of effort into this. So, kudos to you!

Oh don't worry, I made so that dll's are imported in safe mode. If I would remove that, you then could make malicious programs/apps and when I reinstalled my Windows and runned my LoveOS.exe I don't get DirectX message. So I don't know what's that.

What's safe mode? I can't find any documentation on it… it sounds pretty interesting though.

Regarding DirectPlay, can't you just remove dplayx.lib from your linker options? Or better: upgrade your DirectX SDK to this one, the 2006 version is the last one to include it. You do have to remove all of your DirectPlay code, though… which you should do anyway considering that it's been deprecated for 8 years now. As I said, consider WinSock, it's a bit harder to use, but it's up to date.

EDIT: You cant use DLL right now becouse i didnt add them to lua :D/>, I was fast and tired when I released the new update.

Tried the new one. It works well! The Sound is great too! I also get the install direct play, and hit skip every time. There must be an open source game out there to test, or just to have fun playing?

There are 3 things that could use improvement:
Add a version number to each release – I am confusing them now. Maybe the next release is "Alpha 1.4"
The font is still tearing and distorted
The Directplay is an extra step, that seems unnecessary

Umm, guys, DirectPlay is needed for performance and other fix'es. So please install it. Thanks.

A game, I dont know, If someone will make a little game and post it here, ill implement it with your name :)/>

And I will start adding release notes.

Another neat thing ( I think ) is that I will add publisher of the app ( when mouse is over that ) or when you right click the icon.
