Re: [Plib-users] Errors using PW

[Tinoshi K. <ti...@li...>]

Thanks for the answer,

I solved the problem, but I really don't know why. I know how, however: I 
cut&pasted my old code (where I used glutMainLoop() etc... ), put some 
objects into the scenegraph, the sky, the sea etc... used the functions 
begin2D() and end2D() given in viewer.cxx. Everything worked fine. Then I've 
simply commented the glut initialization and main loop and put the pwInit() 
etc.. instead. The crash happened while trying to
glutGet ( (GLenum) GLUT_WINDOW_HEIGHT ) ;
and, deleting this line, in glOrtho(). The strange thing is that if I don't 
show the 2D text and figures (I'm developing a Flight simulator, so I mean 
the HUD etc..) the sea and the sky are displayed correctly, but nothing in 
the scenegraph is drawned.
Well, I re-wrote the whole code, avoided using begin2D() etc... and now 
everything works fine... but I don't know really what happened. It was just 
a stupid mistake I think so I ask you please forgive me, but the gl calls 
are quite the same in the working code and in the crashing one!
The debugger only said access violation for the glutGet(), so I thought that 
it didn't know my pw window's address... or something like that.
Well, excuse me for bothering, but I was going crazy...

May I ask you a few questions? Where can I find a list of changes between 
plib 1.8.3 and 1.8.4? Where can I find source code using plib's collision 
detection not only for HOT, but also for the other two methods?

THANK YOU SO MUCH!!!!
