ODE (Open Dynamic Engine) for Flash
I’ve took Alchemy for a test and decided to compile ODE (Open Dynamic Engine). Just to add yet another physics engine to the Flash World. It was a hell of a ride but I finally got to produce some bouncing balls 
. For a still unknown reason some as 3d libraries have been very slow to render 6 translucent walls and 2 balls. Papervision3D seems to move quite decent.
You can download the ode sources from here. To recompile them do (you need to have the Alchemy environment turned on):
./configure
make clean
cd OPCODE
make
cd ../ode/src
make
cd ../swc
make
And here are the bouncing balls:
Update:
The Source view for the bouncing balls seems to be broken. So if you want to see the source for my little test project here it is.
awesome job, a little bit of camera movement would have helped more to understand what was happening at first, but i guess it would have slowed down the FPS
Impressive,
This engine is also used in world of goo.
I think this is the best engine.
Impressive stuff! I will give it a spin in the near future. Nice work!
Very impressive.
I tried to recompile the library (I added the triMesh geometry and wanted to test it), but encountered problems with ./configure step
The configure process hangs on this step (I\\\’m using Alchemy on MacOs Leopard)
checking whether the C compiler works… /Users/piotr/flex_sdk_340/bin/adl _sb_{SOME_NUMBER}/app.xml 2> /tmp/adl.trace & echo $
I\\\’m sure my Alchemy environment is configured correctly – I followed the instructions
http://labs.adobe.com/wiki/index.php/Alchemy:Documentation:Getting_Started
and managed to compile the \\"stringecho\\" example successfully.
Any ideas why the compilation of \\"ode-flash\\" fails?
Hello,
I tried to get your sources and compile the swc again (to include more of ODE method such as getGeomRotation).
But i have a problem when compiling the swc part… some files are missing or include links are broken.
Can you repost the source files that would work again please ?
Thank you.
By the way i had to install the files in /opt/alchemy/samples/ode-flash to get the compilation works.
@Arthy
I first got the error :
ode.cpp:1:17: error: AS3.h: No such file or directory
So i copied the AS3.h in the swc folder, but then i get errors like this :
ode.cpp: In function ‘_AS3_Val* thunk_dGeomGetPosition(void*, _AS3_Val*)’:
ode.cpp:260: error: cast from ‘const void*’ to ‘unsigned int’ loses precision
Thanks for your help.
sorry my flex config was broken, now everything is going fine except that many many errors are thrown during /ode/src compilation…
mainly from array.h, objects.h and .cpp files…
here is an extract of errors :
array.h:65: error: ‘operator new’ takes type ‘size_t’ (‘long unsigned int’) as first parameter
objects.h:52: error: ‘operator new’ takes type ‘size_t’ (‘long unsigned int’) as first parameter
objects.h:53: error: ‘operator new’ takes type ‘size_t’ (‘long unsigned int’) as first parameter
objects.h:55: error: ‘operator new’ takes type ‘size_t’ (‘long unsigned int’) as first parameter
objects.h: In destructor ‘virtual dObject::~dObject()’:
objects.h:69: error: no suitable ‘operator delete’ for ‘dObject’
ode.cpp: In function ‘dxBody* dBodyCreate(dxWorld*)’:
ode.cpp:249: error: no suitable ‘operator delete’ for ‘dxBody’
any idea ?
