Description
I would like to share with you my ongoing v4 learning project. It turned out to grow into something like a little box2d sandbox. It is not that sophisticated and many box2d features are still missing, so I prefere to call it playground.
Features:
-Drawing basic shapes in three flavours (Box, Circle, Triangle). -Dynamic/static shapes. Density, friction, restitution settings. -Mouse interaction with objects. -Chaining objects by distance or revolute joint. -Deleting objects. -Saving/Loading scenes.
There are still many places to improve and change, but in the end I am pretty happy how it works for now and hope you like it too and have some fun with it.
Ver. 1.1 -Subpatched all the mess. Should make more sense and be better readable now. -Triangles are now made with woei´s mesh join, so each is a subset. -Many small changes and optimizations in several places. -Added evaluation triggers for some parts that do not need to run all the time. -Added revolute joints to create hinge like connections. -Runs well in 45beta27.2 and AddOnPack
Ver 1.0 -Initial release. -Runs well in 45beta25.1 and AddOnPack

its fun, tomek :)
yes, really nice work!
glad you like, herr angel. learned a bunch of stuff again.. cheers thanks for the kind words sunep
nice box2d demo bravo!
great work and idea! not too far to a complete 2d phisics sandbox like phun (now algodoo). after triing it i was wondering about making the text example look like fluid.. some sort of 2d metaballs could do the job maybe? anyhow, nice stuff!
thanks guys. I have tried to make fluid but run into few issues. Biggest one seems performance, at least on my PC is not so good. I have tried MetaballsSpreaded /tiki-download_file.php?fileId=1609 with about 400 circles. With that much elements it begins to look kind of fluidish, but the framrate goes down quickly. It is not easy to find right settings of the Metaballs to look right too. Second issue is scaling the Metaballs to different aspect ratios of the screen. Have to dig it bit more. The circles do best when having zero friction and about 0,5 restitution. will post the fluidtest next days. seems doable somehow. cheers
looks great.
p.s added only one comment, one like. So nobody entertain suspicion ;)
@tgd if have time please contact me. thanks
Really nice box2d demo !!
This one ROCKS!
fun...:)
Updated to 1.1 :)
very nice update!
Hey there,
I want to use box2D in a project with vvvv_45beta34.2_x86. I know that the playground contribution is optimized for beta27.2.
Is there any newer version of the contribution?
Also looking for a working version. I always have a red R -- world bodies.
Just to clarify: This thing relies solely on the awesome box2d nodes provided by vux in the vvvv addonpack. Due to changes in the vvvv core these are unfortunately out of order in the recent vvvv versions. Please see box2d-in-beta34.2-broken. Lets hope there is a chance vux can make them work again sometime.
