Game Development

yes it's work!
now I can loadTexture from secondGLWidget
and then use it in firstGLWidget

Thank you very much.

After read the opengl_es2 exsample, i know that by default the (0,0) coordinate (in my case) is center of screen.

and i do this to move the (0,0) coordinate to top-left corner. I multiply vertex with a (4x4) matrix.

@
_projectionMatrix.Identity();
_projectionMatrix.Ortho(-(float)k_SCREEN_WIDTH,+0.0f,+0.0f,-(float)k_SCREEN_HEIGHT,-1.0f,+1.0f);
@
the code to Identity and Ortho can be found "here ":http://db-in.com/blog/2011/04/cameras-on-opengl-es-2-x/

Thanks everybody!
p/s : My english is very limited to representing my idear :D

If you ever look for general game development questions, look here "gamedev.net":www.gamedev.net

Perhaps "this":http://pc12-c714.uibk.ac.at/GPLIGC/GPLIGC.php can be a starting point?

I doesn't know if anyone already had the same problem, or if the major part of you didn't get the point, or if it's because nobody had this problem and can't solve it.

I feel quiet alone here x).

Did you miss this part in the question:
[quote]is it possible without using C++?[/quote]

Using QSettings requires using C++. If you want to stick to QML only, you can only use the Offline Storage API.

actually after carefully looking at my codes and modifying it.. I found the problem on my .js file so its working already. thanks for the help guys

Yes I did. after 20 + times there shows an error

Qt3d would be a good fit for interactive applications for kids.

Yeah I did. Thanks :D It really helped me a lot :)

thanks for your help.

I uploaded a video which helps me to explain my issue.

I am using the same code in the penguin example just changed the 3ds file name.

After all I solved the problems myself, with help and useful advices of koahnig (really thanks for that!)... I left the interesting fragments (with the problems) and posted the solutions, so if anyone meets up with the same problem he'd probably read what he need, learn and correct. What's the point of posting here the whole source of the game? If u want to play it then I can upload the Release...

Thank you all, depends.exe is awesome tool :) As I said before we did it :) I will make sure to share a link here to a website after the game is finished :)

Looks nice. The Butcher reminds of the first boss from Diablo I.

First strait OpenGL isn't trivial and isn't for most people, just knowing how to program in C/C++ and the OpenGL api isn't enough you need a background in advanced mathematics. Also if your doing things in the wrong order or if your not in the right mode at the correct time you will end up with a different result than what you expected. When programming in OpenGL you have to think of it in a procedural mind set. Post a link to your complete source code if you want help.

As you wish. This topic has been split off from "Welcome":http://developer.qt.nokia.com/forums/viewthread/86/

Anyone knows if its possible to use 32 bit precision floating point textures with a 3D texture?
