Hi,
and again im a bit confused :shock:
I dowloaded some of the Nehe Ports avaible on :
http://chman-area.tuxfamily.org/links.html
To be exakt i tired to launch the Lesson 06 - Simple Rotate Cube
So, good, i setup the Project in JBuilder 9 (i know that IDE very good)
All needed jars were found, but the Lesson seems far from Compileable ?
As example (static init):
static
{
try
{
// Create The Display Mode
int mode = -1;
DisplayMode[] modes = Display.getAvailableDisplayModes();
for(int i = 0; i < modes.length; i ++)
{
if(modes[i].width == 800 &&
modes[i].height == 600 &&
modes[i].bpp >= 16)
{
mode = i;
break;
}
}
[b]Display.create(modes[i]);[/b] }
catch(Exception e)
{
System.exit(1);
}
}
Is not Compileable, the reason for this seems that the Method has
changed into Display.setDisplayMode(Displaymode).
And if i go down the Source Code from Lesson 6 more such things come
to Daylight eg.
In Class Gl im unable to find a Method called GL.swapBuffers()Im using 0.7 of lwjgl is it the right one for these Examples ?
thx,
Jens
is the version of lwjgl you're using pre-0.7 or the one in CVS at the moment?
if it's the one in cvs, you should be able to do it like so:

Thx 4 fast Answer, i love that :D
Im using the actual avaible version 0.7 from http://www.lwjgl.org/
I will try it now.
- Jens
Hmm,
it must work if i could get the latest Sources...
I found the GLWindow Class in the repository, this one of two
i cant find while try to Compile the sourcees
Im new to CVS, what name "modulename" will the CVS Client have to Checkout the whole Project ?
- Jens
I'll send you a working copy - but it will have to wait some 8 hours, since I need to get to work...
Fine,
i found out were to find the Modulenames in CVS :roll:
Hope that i can make the first test with LWJGL for my PlugIn
Interface for my Player Project. :D
Actually i have designed some Interfaces and Services for
PlugIns to use.
- thx
Jens
just following up... you need binaries from me ?
Yep,
i was trying Smart CVS (Webstart Version)
and was unable to checkout the project, i fyou
could post also some "were to checkout the modules" ?
I have tried this with module name "lwjgl" , but the source never
saw my harddisk :cry:
If possible send the binaries to this mail address :
java-code@mac-systems.de
thx,
Jens
Thx 4 Binaries.
Have done the first simple things.
Seems to be very stable and performs very well.
