trace(member("Physics").getSpring("test constraint"))
-- spring("test constraint")
trace(member("Physics").getSpring("linear"))
--
trace(member("Physics").getConstraint("linear"))
-- constraint("linear")
For similar reasons, the physicsMember.getConstraints() function will only include joints in the output list.
trace(member("Physics").getConstraints())
-- [constraint("linear"), constraint("angular")]
To obtain references to all the springs created within a Physics member, you need to use the
physicsMember.getSprings() function.
trace(member("Physics").getSprings())
-- [spring("spring")]
Deleting a joint or spring
To delete a joint or a spring, you can use the physicsMember.deleteConstraint() method. You can provide either the
name of the object to delete, or a reference to it.
trace(member("Physics").getSprings())
-- [spring("spring")]
trace( member("Physics").deleteConstraint("spring"))
-- 1
trace(member("Physics").getSprings())
-- []
vAngularJoint = member("Physics").getConstraint("angular")
trace(vAngularJoint)
-- constraint("angular")
trace( member("Physics").deleteConstraint(vAngularJoint))
-- 1
trace(vAngularJoint)
--
Note: If you conserved a reference to the ConstraintDesc that you used to create a joint or a spring, the ConstraintDesc
will now be available for use with another joint or spring.
For only springs, you can use the physicsMember.deleteSpring() method. If you attempt to use this method with an
object that is not a spring, a script error occurs. It will fail silently if you use it with a string that is not the name of a
spring.
Angular joint properties
An angular joint between two objects allows those objects to rotate freely to any angle with respect to each other.
However, the distance that separates the two objects is constrained.
For information on how to create, access, and delete an angular joint, see “Joints and springs” on page 330. To
experiment with the way an angular joint will link two rigid objects together, download the movie AngularJoint.dir.
