The ODE guys have helped me a bit.
I'm newbie. I want to create an object no affectec by forces (always moved manually) but that can be check if is touching/penetrating into another objects. Can that be done?
<vicentecarro> Or another focus. When 2 objects collide both receive forces in the oposite direction (sorry, I explain as I can
). Can I disable those forces in a coliision? In that way the object could penetrate other objects.
<kpreid_> vicentecarro: yes
<vicentecarro> kpreid_, how?
<kpreid_> vicentecarro: all you have to do is, in your collision callback, if one of the objects is your special object, then don't create contact joints
<vicentecarro> ok...I'll try. I guess there is no example code of that, right?
<kpreid_> probably not
<kpreid_> but it really is that simple
<vicentecarro> ok, thanks you
<kpreid_> well, there's another approach
<vicentecarro> ...
<kpreid_> this might be useful depending on what you want to do:
<kpreid_> don't put the geom of the special object in the space the rest of your moving objects are
<kpreid_> but when you want to check it for collisions, use dSpaceCollide2 to collide it vs. everything-else
<kpreid_> this is good if you want to be able to choose to test just that object at some particular point in your code, independent of the regular simulation
