Say maybe in world settings "Apply physics [2d,3d]".  It'll be very usefull for just 2d based games that might just want to use 3d graphics.<br><br> <img class="smilies" src="https://pybullet.org/Bullet/phpBB3/images/smilies/icon_wink.gif" width="15" height="15" alt=":wink:" title="Wink"> Yeah, I know about the use of constraints, restraining the 3d objects onto a particular plane.  However, that doesn't work 100% of the time it sometimes it still ends up shifting the object outside of say the z plane.  Instead of being at 0 for z where it should be through the use of constraints.  It might end up being at +1 or -1, something like that after several collisions with other 3d objects.<br><br>If it doesn't require too much of an effort, it'd be great if you can provide an option for it.<br><br>Jason Lin<p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=346">goldentaiji</a> — Sat Nov 19, 2005 5:33 pm</p><hr />
