In reactor, you define the effect of constraints by the specifying and
manipulating two
constraint spaces on page 3927. Limits, such as minimum
and maximum rotation angles, are defined and displayed around those spaces,
which you can modify using sub-object manipulation. reactor provides tools
for automatically aligning and manipulating those spaces.
Storage and Access of Collision Information
reactor can store information of all rigid body collisions occurred during the
simulation. The information includes the objects involved, the point of
collision, and the relative velocity during collision, and can be used by
animators to generate particles or other effects, trigger sounds, etc. You can
access the information via MAXScript and save it to a text file.
