Hi again, Im going on with the development of my shmup project for Win32/DC under = Tiki, i made great advances about the engine with the help of the = environment: --- Im having a great problem, so if this letter is to large, please read = the last paragraph. Thanks --- First of all, im interested in backup my project under sourceforge = because everyday i fear to lose everything from my computer. Could = someone give some directions to do it, please? Regarding the project, as i said everyday im more impressed with the = whole implementation of the Tiki dev: Everything i have already done in = my engine, is better implemented so my engine is more like an equivalent = layer of the Tiki one, with things like object count references, hid = callbacks, HW timers, threading!! and such... I mixed with the use of = the minixml lib and I hope "everything" could be parametrizable from the = XML trees and files... I have already put an fps counter with a font = texture under OpenGL which works fine (60 fps on Windows and DC!!!)... = So now its time to start with the graph scene (i was doing my own, but i = will use the Tiki one again!!!). By the way, i did another change on the windows callback function: On = the switch(msg) part i added some breaks for the WM_KEY's which were = screwing my HID callback system!! I dont know if anyone else has been = affected with the problem... Ok, then about the graph scene system: After checking the DCBlap = sources and discovered the gs and the Generic Menu class i am developing = my level manager as a subclass of it redefining the ControlperFrame = functions, hope its ok...=20 And now im running with some troubles, the second one its my MAIN = problem right now: - About importing meshes, what can i do to improve speed, on my = project? On the old DirectX project I used an indexed vertex buffer, = can i use something alike under kgl? checking some Nehe tutorials i saw = display lists are supported, are they ok? In the KOS GL headers i saw = about opengl 1.2 arrays? What are they? Could some address me, please? - Finally, Ill explain my MAIN PROBLEM right now, i wont be able to go = on with the project if i cant resolve it.... It's about a camera system: My old project used only ONE camera, based on UVN rotations which = always followed the player, this meant that i never had to use = Yaw/pitch/Roll angle rotations (sadly, i dont know if i can reach again = the person who taugh me about it), but i realized that if i want to = debug the 3D scene of my game i need to develop some cameras (mainly a = FLYING-FPS and a TPH camera, and of course the game camera) and if its = possible, I WOULD LIKE TO DEVELOP THEM UNDER THE UVN system, so i think = it will be faster than with the angle system (before asking why, chech = this article http://www.gamedev.net/reference/articles/article1199.asp) = .. I realized that my knowledge about rotations, the matrix stack and = the math behind OpenGL/DirectX is zero!! I tested the Tiki::Matrix = rotation axis function but everything screwed up when i move the camera, = even the debug text!! =20 Please, every detailed tutorial, code sample or explanation about the = UVN math (matrix, vectors), the Opengl matrix stack, and matrix = conversions to OpenGL or anything about the subject will be welcomed!!

I have a little experience programming in windows, but i have read that the Windows Message dispatching must = be accurate so it doenst eat all the machine resources.... I have tried = a small=20 change on platgl.cpp on the DoMain function, and i think it works = better now. Here are my changes, tell me what you think, i think it respect = the multithreading in windows better. - Changed: /*while(m_hThread !=3D NULL && GetMessage(&msg, NULL, 0, 0))=20 { TranslateMessage(&msg); DispatchMessage(&msg); }*/ - To: while(m_hThread !=3D NULL) { do { if (GetMessage(&msg, NULL, NULL, NULL)) { TranslateMessage(&msg);=20 DispatchMessage(&msg); } } while (::PeekMessage(&msg, NULL, NULL, NULL, PM_REMOVE)); Sleep(2); } I have tested it and it works fine on breakpoint and exceptions... @B^)> ----- Original Message ----- From: "Sam Steele" <sam...@gm...> To: "General Discussion about the Tiki Toolkit" < cad...@li...> Sent: Friday, April 20, 2007 3:26 AM Subject: Re: [cadcdev-tiki] [Tiki-win32] Unable to compile tikisnake >I checked in a Visual Studio 2005 project file for TikiSnake.
