Jonathan,
I made some games in opengl this time last year (which now seem quite
naive, as i did not know opengl or cocoa, so they could do with a good
refactor).
I do not know if they work with the current version of macruby but they
are on my idisk:
www.johnmacshea.org
navigate thru MacRuby / Game Related / Mine
Two 2D games CarNage8 and IcePhage9 are there.
They do screen setup, texture loading, writing text to opengl scenes (two
different ways), canned explosions sometimes and particle effects for
other explosions.
They do not use VAs or VBOs - but I do have some test projects which use
VAs and VBOs, and a 3D test (which uses an exported c header file (from
Cheetah 3D) holding vertex arrays).
Let me know if you are interested and I will dig them up and send them to
you (only tested on MacRuby 0.4 however).
In that game related folder you will also see translations from other
people's opengl work (also only tested on 0.4)
Cheers,
J

John,
Thank you for the response. GLUT won't be my first choice but I'm trying
to follow the examples in the SuperBible.
I'm wondering what the plan is to support all the 'standard' frameworks
in MacRuby is? Should I be able to process the GLUT.framework with
gen_bridge_metadata?
Meanwhile I will look at providing my own wrapper class as you suggest.
As you say this provides a flexible way of handling any framework that
lacks bridge support.
Many thank, Jonathan

Yes as far as I know bridge support does not support GLUT.
So you (obviously) have two other options other than
gen_bridge_metadata (which I gave up on after a few tries) :
- don't use GLUT - use the equivalent (set of) non GLUT openGL calls
- place the GLUT calls in an ObjC class - and call out to that class
from MacRuby
you might find that the second option is quite quick - i found that for
some openGL calls (but not all) that dispatching to my own bridge class
which then called opengl functions was quicker than going through
BridgeSupport.
There are other good reasons to have your own bridge class anyway - i
imagine that BridgeSupport is always going to be lagging Cocoa a bit
(eg Core Animation constants), and it might just be easier allocating
OpenGL texture memory in ObjC (well I still use objC for that)
HTH,

Hi, I'm back to using MacRuby again and I'm confused about Bridge
Support.
I have been using the excellent sojaster port of the Cocoa OpenGL
example to help develop an OpenGL playpen. However, when I started
using glut calls (glutBitmapCharacter, glutStrokeString, etc) I
started to get problems.
It seems that the OpenGL glut.framework (10.6.2) doesn't include
bridge support. I've tried using gen_bridge_metadata to add bridge
support but without success.
Should glut work in MacRuby? How does one add BridgeSupport to the
Apple shipped frameworks?
Sorry if I have missed some very obvious step.
regards and thanks, Jonathan
