Jumping between towers

I got a lot of things working today, but the game doesn't look that different. The main new mechanic is jumping between adjacent towers, which you do by simply getting close enough and running in that direction. The main skill you'll have to acquire is getting the towers to sway enough to get close enough.


Behind the scenes, I got fast model loading accomplished using the lessons learned from my warmup demos, and I got some text to appear on the screen, which I've never done in OpenGL before. It doesn't seem to hurt the framerate much.

I still haven't decided what the protagonist will be, so for now you control an enemy, a castle guard.

At first it crashed, made some adjustments and then succeed
in windows xp, pyOpenGL 3.0.1 (the latest released in sourceforge), at the start crashes with:

OpenGL.error.NullFunctionError: Attempt to call an undefined function glutBitmap
String, check for bool(glutBitmapString) before calling
 
Workaround:
seems that glutBitmapString is not available in the standard glut32.dll shipped in the win binaries for pyOpenGL
greping the pyOpenGL sources with the func name suggested that freeglut was needed
got freeglut (I choosed the MSVC version) from
 http://www.transmissionzero.co.uk/software/freeglut-devel/
copied freeglut.dll to site-packages\OpenGL\DLLS
renamed to glut32.dll
in %windir%\system32 rename glut32.dll to something else
 
Done, it runs (and the text shows)
Windows
I had the same trouble. Thanks, claxo, for the workaround.

I got up to about 208fps, but it seemed to hover closer to 190 most of the time.  When I had a bunch of other apps open I was seeing around 180fps. The sway numbers are nice; they help me optimize my running.

On my native linux machine
(finally got it updated) the game played fine except I could not read any of the text.  Just  a few of the horizontal lines were there, so it was illegible.

linux in VirtualBox
Game played well, except I still had crazy behavior based on mousemotion.  I tweeked those same lines again (which you moved to camera.py) until I could play it.  The graphics and text looked fine.  I got 28fps, but it was about the same response as with windows.

All of my platforms have trouble when I quit the game. I have just been killing the processes after I quit.
OK, my native linux machine is an old laptop and the 12" screen resolution is only 1024x768 so I think that explains the text.
