using jit.phys.picker without mouse
I would need to grab and move object in a jit.phys world , but not using my mouse (for example, using messages coming from a multitouch screen..)
unfortunately, jit.phys.picker doesn’t seen to accept any external message to replace clicking with the mouse in the jit.window.
so here is a feature request :
please add a "mouse" message to jit.phys.picker that would allow to use it without clicking in the jit.window
(and maybe a "mousemode" attribute to select mode ?…)
sending
mouse 130 345 1
would do the same as clicking in the window at position 130 345, and would select the closest object and grab it
mouse 134 348 1 –> drag the previously selected object
mouse 134 348 0 –> release the object
could this be an option for a futur version ?
or is there another way to achieve the same with another method ?
(AFAIK, there is no simple & easy solution in jitter to test witch object is at a specific screen coordinate… (?) )
thanks

one possibility, not very elegant, is to use autobot ( http://sites.google.com/site/theoldmanthesea/download ), which emulates the clicks of a mouse.
thanks for this reply, sandroid.
but this is not an option for me, because I want to be able to control several object at a time (–>multitouch)
.. and I need my mouse for other purposes !

hi mathieu. thanks for the suggestion.
request noted, and will show up in the next update.
can you describe further what you mean by "mouse mode" ?
thanks.
Thanks, Robert !
I’m looking forward this new feature :-)
"mouse mode attribute" : I mean that it will probably be useful to disable mouse click in the jit.window when using messages ; for example :
if I want to use a multitouch screen to grab several objects, I will have to create several jit.phys.picker objects, and actually, it doesn’t seems to be possible : only latest created object works.
so maybe a simple "mouse" attribute would do the trick :
mouse 1 (default) : allows mouse click & drag in jit.window (+ messages ?)
mouse 0 : disable mouse, and use messages only.
by the way : it could be as well very useful to be able to set constrain strength (relaxation ?) when controlling an object with this method.
thanks in advance !

ok, thanks for clarifying.
phys.picker is really intended to be used 1 to 1 with the mouse and phys.world
however, i think we could add a screentoworld type message to jit.phys.world, that will return object names that intersect. this feature was actually built in to a previous version, but has been removed.
this way you can send screen coords to world, get the name of an intersecting body, and create a constraint on that body (phys.picker is simply a phys.point2point constraint), and you can manage as many of these as you need.
would that fulfill your needs?
phys.picker constraint attributes are already planned for a future update :)
Hi Robert
I was about to request a screentoworld "ray casting" in another post, so YES, that would be great, thanks !
but if this message returns only the object’s name, I will only be able to grab it by its center..
could it return object’s local coordinate as well ? (the intersection position)
and with this method, it will be probably more difficult to manage the phys.point2point 2nd point’s position..
well, these 2 solutions would be very useful, so if we could have the best of both worlds, I would be very happy !
(mouse messages + screentoworld)
Mathieu
yes, i think it would return object name, local intersection (object relative) and world-space intersection.
thanks!
hello. is this option avaiable now in max? I’m need the same tool to use with kavl kinect tracker. thanks
hi,
touch message on "jit.phys.picker" works pretty well
