about

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.

Changelog

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

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!

tgd 10/08/2011 - 12:25

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 !!

robe 17/11/2011 - 20:20

This one ROCKS!

dannielmach 17/11/2011 - 21:13

fun...:)

tgd 18/06/2012 - 21:53

Updated to 1.1 :)

bo27 19/06/2012 - 00:26

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?

levi: thanks guys,not so eager for the purist solution,could use some sophisticated interface,probably some lightning-dmx software.

mino: I'm going to London at early June. anyone there?

catweasel: @levi also https://vvvv.org/contribution/kontrol-evvvverthing theres an update on Github, but I'm not sure it has a help patch yet. Need to make a video still

microdee: @levi: vvvv's builtin timeliner. it's not the fanciest out there but does the job

~2d ago

levi: any timeliner reccomendations anyone? need some accuracy and nice grouping functionalitys for bunches of values and scenes
