What are you working on? v15

[QUOTE=Darwin226;27618720]Aren't you supposed to use glOrtho or what ever it's called for non-3D stuff?[/QUOTE]

Yes but, it's just drawing polygons and I am going to be rendering 3D stuff. I've tried pre-transformed vertices and that didn't work.

[Overv]

I hope this API matter is solved as soon as possible. I don't want to throw code around because the whole authentication system changes. I'd rather just use a public API.

[HiredK]

Lightmap. Thanks layla, your source code has been really useful :v:

HiredK you're making some real progress there.

[Nipa]

Wow, that actually looks pretty decent! You're making very good progress.

Why is declaring vectors in OpenTK so complicated?

[QUOTE=likesoursugar;27618273]I have som problem with std::string... When I call lenght() the function return a random number like 24353455. I'm doing this in a class function which is in a lib... I'm totally locked.[/QUOTE]

Try calling size()

Next up, I need to figure out how to use textures in opengl. Any hints, HiredK?

This is silly. You need .Net 4 to load projects? Anyway, I can't make it work, I've reinstalled .NET 4 many times now with no progress, what should I do?

Fixed Fructose to allow for nested blocks (which only turned out to be a [url=https://github.com/charliesome/Fructose/commit/86cb48a2b982fd319d541d51e142dcc48eb63f71]three line change[/url].) So now this works:

Anyone knows how to have a global key hook with Python under Linux, like what [url=http://sourceforge.net/apps/mediawiki/pyhook/index.php?title=Main_Page]PyHook[/url] offers under Windows?

How do you do mouse control stuff? Like moving a camera around?

[QUOTE=ZenX2;27623492]How do you do mouse control stuff? Like moving a camera around?[/QUOTE]

1. Get mouse position relative to center of screen.
2. Do stuff such as rotate camera based on values.
3. Set mouse position to center of screen.

[foszor]

Progress on my Android game. Its fundamentals are based off Pac-Man, but its totally physics based and I'm going to add powerups and such. The levels are going to be much larger, so the camera scrolls around with the player. I just finished adding a particle effect under the players feet as he moves around.

So where would I call TextureLoader::load?

If you're not making a fast-paced first person game, this is fine. Otherwise, you'd want to use raw mouse input. If you're using Windows, [url=http://msdn.microsoft.com/en-us/library/ms645536%28v=vs.85%29.aspx]this will help[/url]. Additionally, you'll want to use ClipCursor() to keep the mouse from leaving the window rather than re-centering it.

Raw mouse input has a few advantages:
-Input is given in relative coordinates
-Windows' (or other OS) cursor ballistics doesn't mess with the data
-Sub-pixel cursor movement still registers (see above)
-Input can be hooked rather than polled (In Windows, use the message WM_INPUT)

Just remember to remove the cursor clip when the window loses focus or the user enters a game menu. Only use the cursor clip when the player can aim.

[editline]23rd January 2011[/editline]

I noticed someone posted a border-removal program. I have an open source C++ program people may be interested in.
[url=http://eagle.undo.it:8083/project/?id=4&act=info][img]http://eagle.undo.it:8083/project/?id=4&act=img[/img][/url]
The "noborder" feature of it works like this:
Position the center of the window you want to "noborder" on the desired monitor. Press RWIN+ENTER. The currently active window will be resized to the appropriate monitor's resolution and so on.

The only problems I have with it is that the way it hooks the keyboard could be improved. Also, sleep mode sometimes breaks it. Any tips?

I was messing around with words in Java today and made a [URL="http://tallcorporation.co.cc/projects/words"]random phrase generator[/URL].
It isn't complete yet because it lacks some word types and the word-relationship system isn't ready for use, but it's proven amusing to mess around with.

Yes, is that backwards?
