Comments on: Box2D SVG Parser with Curve Support

@Epic: Should be easily doable. With a little work you could change the position of the line-segments in the “shapes” array from the parser. There should be no problem calling the parser multiple times and adding the returned arrays to the world.

Hey, just out of curiosity, could I use the parser to create individual objects? Like for example say i wanted several different bodies in my world each using a different .svg file.

I assume this could be accomplished, I just need to view the source and see how the bodies are created given that function call and then manipulate it to work the way I need it to.

Anyway, I’m glad I asked in the box2d forums on how to make curved shapes as this seems to be the direction they pointed me and it looks great!

@pushparaj
I haven’t messed with the latest versions of the C++ or Flash versions of Box2D, so I can’t comment on that.

You can find an older version of Box2D that should be compatible with the parser here: Box2DAS3

Other than that, my only advice is to see if the edgeChains were renamed to something else in the latest version.

Looks like it is a great work but I am not a Flash developer so I have been trying to port this into C++ but the latest Box2D does not have b2EdgeChainDef. Did you get a chance to get it compatible with the latest version of Box2D?

Hm, are you having problems compiling Box2D as a whole or only the parser? I assume you probably have your SWF properties set to reference the Box2D folder? (In Flash, File -> Publish Settings -> "ActionScript 3.0 Settings" -> Source Path) The error sounds like it isn't finding the Box2D files, which is odd, but my only suggestion for now is to make sure the SWF knows the correct filepaths and that the b2SVG class isn't in a lone package or something odd that would interfere with it finding the files. I'll let you know if I think of more possible solutions, but you might want to ask the guys down at the Box2D forums if nothing is working.

hey. thanks for the speedy help!

i’m still just trying to compile the parser, but it’s still giving me the same error. is it my file structure that could be causing the problem?

i’m just baffled as to why an instance of b2EdgeChainDef isn’t inheriting values from b2ShapeDef

Hm, based on your comment I assume you’ve already tried v2.0.1 on the Box2D frontpage along with the SVN.

The current SVN was updated to be 3-4x slower (revision 52) and was changed around a little bit, which might be the cause of the errors.

I’ve uploaded the copy of Box2D I’m using at the link below:
http://www.ezqueststudios.com/source/Box2DAS3.zip

Give that a shot and tell me if it works.

i’m getting some strange problem when i’m trying to compile the code…

1119: Access of possibly undefined property friction through a reference with static type Box2D.Collision.Shapes:b2EdgeChainDef.

this is at line 43: ‘chainDef.friction = 0.5′

i downloaded the latest SVN repository, but i saw that in the b2EdgeChainDef.as that ‘extends b2ShapeDef’ was commented out.

i uncommented this but still get errors. am i doing something wrong?

Check the Box2DFlash SVN Repository:
http://www.ezqueststudios.com/blog/creating-levels-box2d/

Getting an SVN client working and getting the latest copy might take a little time, but there’s a few updates there you cannot get in the public release.
