Hey…. I found this tutorial really helpful but am facing a problem. When I try compiling any of the files given, I get an error saying:

2.1a_2\Source\Box2D\Dynamics\b2World.as, Line 871 1046: Type was not found or was not a compile-time constant: b2Fixture.

Please do help. I need this for my project really quick.

Thanks

Hi, guys.

You need to have the following in order to successfully run Demo.fla.

1. Adobe Flash CS4
2. Box2DFlashAS3_2.0.2

Download Box2DFlashAS3_2.0.2 in here.

http://sourceforge.net/projects/box2dflash/files/

If you have any questions, ask. :-)

Thank you for the great tutorial, Emanuele! You rock!

Hi,

just so you know, I’ve been struggling all day with this (otherwise amazing) tutorial, and finally managed to make it work, but some important changes occured in the last version of box2d.

A list of some of them is available here : http://box2dflash.boristhebrave.com/docs/2.1a/updating

for example, b2World creator takes now 2 arguments instead of 3, b2World.Steps takes 3 instead of 2, debugDraw properties cannot longer be set dynamicaly but by calling methods (debugDraw.SetFillAlpha(0.3) instead of debug_draw.m_fillAlpha=0.5) and so on.

Thanks all the same and keep up the good work.

Vincent

Hi. Does anyone know if I can set my Box2D world inside an existing movieclip, instead of in the stage?
Thank you

1. Can you describe how to set the gravity for the earth?
2. What are the major diffences between version 1.4.3.1 and 2.0.0.0?

@Arxanas – it was ported to AS3 mainly because AS3 resembled C code in the way it works and occasionally in layout too – making it easier to work and definitely very fast.

AS2 would probably be too time consuming and slow to use, though I tried porting it once. I should probably finish that…

YES! I will soon enough figure out AS3!

Just wondering, but is there any specific reason Box2D was ported into AS3?

Does AS2 lack the functionality needed to make Box2D work, or is AS3 the choice because it is more powerful?
