Hi everyone,

I’m working in a game with physics using Away3D 4.0, and I’ looking for some advice on what is the best physics engine (performance, compatibility with away3D 4.0…).

Thanks!!

P.D. I’m woring now with bulletflash

The BulletFlash project has been merged take up into the Away3D family, and is now called AwayPhysics. We will be integrating it very tightly, so if you need 3D physics in Away3D, AwayPhysics will be the best way.

You can find the code on GitHub, in a repository called awayphysics-core-fp11.

thanks Richard!

That’s some really cool news!  Can’t wait to sink my teeth into it!

When I try to compile the awayphysics library via one of the awayphysics examples,  I get this error:

“Definition cmodule.AwayPhysics could not be found”

Looks pretty simple to fix though.  Because if you look in the awayphysics package, there is no “cmodule” subdirectory.  Maybe someone forgot to include it when they committed to Github?

I think that means you need to get the AwayPhysics.swc file from the libs folder and link it into your project.

thats right, awayphysics is based on alchemy, so it needs the swc compiled from c++ code

it should be in the lib folder

Thanks guys.  I added the swc to my library paths in Flash Professional and it now compiles without errors.  However now I get the following error at runtime:

VerifyError: Error #1014: Class cmodule.AwayPhysics::CLibInit could not be found.

at global$init()
at VehicleTerrainTest/init()
at VehicleTerrainTest()

Strange…looks like it now finds cmodule.AwayPhysics at compile time but can’t find it at runtime.  Any suggestions?

hmm, that’s weird - perhaps its a Flash issue. I haven’t used Flash for compiling for a while, why don’t you do a little research on how to use an alchemy compiled swc within Flash?

I figured it out.  I had to point to the swc for the “Library Path” instead of the “External Library Path”.  One would think it were up to personal preference, since “Library” should be any libraries you might use only for that project while “External Library Path” says it’s supposed to be for libraries you want to use across different projects.  At least that’s how I read it.  But I couldn’t for the life of me find that particular dialogue window of Flash Professional (Edit>Preferences>Actionscript>Actionscript 3.0 Settings…) in the Flash documentation.  I’d love to know the official definitions.

Oh well.  It works now anyway.  Thanks.

cool! glad you solved it
hope you have fun with AWP, its awesome

Hi! I met the same problem, and I used every method ,but it still exit ,cmodule.AwayPhysics could not find,CLibInit is undefined…!oh ! my head !
