Measurements in the physics world are not related to the number of pixels in an image, so you can make the graphics at whatever size suits best. For example, let's say you have a platform game where the player characters are 1 unit tall in the physics world, and you want the player character's heigh...

I think you just need to change the OR here to and AND:

Hi nik Firstly these bodies might be a bit long and thin to get a nice stable simulation, you might want to add a bit more rotational inertia (eg. another fatter fixture, could have collision filter mask set to zero so it doesn't actually collide with anything). However, it seems to run ok though......

Glad to hear you got it sorted out

Well, "horses for courses" as they say. I agree that if there is any single language that could be nominated as the most useful, practical, efficient etc over the past, present and no doubt long into the future, C++ would be it. But that doesn't mean scripting languages don't have any adva...

The 'instantiable object' would behave like a template that could be used to place many similar things around the scene, all referencing the same master object template. Editing the master object would cause all instances of that object in the scene to be changed. So in the .rube/.json file, there w...

It looks like you are using the source code from this page: http://www.iforce2d.net/b2djson/ which only handles the JSON produced by the older free version of RUBE which does not know anything about images. Use the b2dJson sources included with the RUBE download, they include the support for images....

Being able to run your game in a browser is obviously the main advantage, but there are many others... cross-platform by nature, instant distribution to any browser on the planet, less worries about memory management, no compile time, easy networking capability, easy image loading, easy serializatio...

Yes you would need to add a declaration in the header like that.
I'm not sure why those errors would happen.... would you be able to attach/pastebin the b2dJson.h file?

The original source is included in the trial version download. I figure smart people like yourself will look at the html in the demo page to see what's going on, but it has to be commented there to avoid messing up the page. The actual loading of the scene is done in the createWorld() function in th...
