"""Add a physics constraint to an object"""

"""
|
||||
Add a physics constraint to constrain two rigid bodies if not already present.
|
||||
|
||||
@option Fixed: No fredom of movement. Relative positions and rotations of rigid bodies are fixed
|
||||
|
||||
@option Point: Both rigid bodies are constrained at the pivot object.
|
||||
|
||||
@option Hinge: Constrained objects can move only along angular Z axis of the pivot object.
|
||||
|
||||
@option Slider: Constrained objects can move only along linear X axis of the pivot object.
|
||||
|
||||
@option Piston: Constrained objects can move only and rotate along X axis of the pivot object.
|
||||
|
||||
@option GenericSpring: Fully custimizable generic 6 degree of freedom constraint with optional springs. All liner and angular axes can be constrained
|
||||
along with spring options. Use `Physics Constraint Node` to set a combination of constraints and springs.
|
||||
|
||||
@seeNode Physics Constraint
|
||||
|
||||
@input Pivot object: The object to which the physics constraint traint is applied. This object will not be affected by the constraint
|
||||
but is necessary to specify the constraint axes and location. Hence, the pivot object need not be a rigid body. Typically an `Empty`
|
||||
object may be used. Each pivot object can have only one constraint trait applied. Moving/rotating/parenting the pivot object after the constraint
|
||||
is applied has no effect. However, removig the pivot object removes the constraint and `RB 1` and `RB 2` are no longer constrained.
|
||||
|
||||
@input RB 1: The first rigid body to be constrained. Must be a rigid body. This object can be constrained by more than one constraint.
|
||||
|
||||
@input RB 2: The second rigid body to be constrained. Must be a rigid body. This object can be constrained by more than one constraint.
|
||||
|
||||
@input Disable Collisions: Disable collisions between `RB 1` and `RB 2`
|
||||
|
||||
@input Breakable: Constraint can break if stress on the constraint is more than the set threshold. Disable this option to disable breaking.
|
||||
|
||||
@input Breaking threshold: Stress on the constraint above which the constraint breaks. Depends on the mass, velocity of rigid bodies and type of constraint.
|
||||
|
||||
@input Limit Lower: Lower limit of the consraint in that particular axis
|
||||
|
||||
@input Limit Upper: Upper limit of the constraint in that particular axis. (`lower limit` = `upper limit`) --> Fully constrained. (`lower limit` < `upper limit`) --> Partially constrained
|
||||
(`lower limit` > `upper limit`) --> Full freedom.
|
||||
|
||||
@input Angular limits: Limits to constarin rotation. Specified in degrees. Range (-360 to +360)
|
||||
|
||||
@input Add Constarint: Option to add custom constraint to `Generic Spring` type.
