ConstraintEditor

vtool.maya_lib.space.ConstraintEditor()

Convenience class for editing constraints.

class ConstraintEditor

Convenience class for editing constraints.

constraint_parent = ‘parentConstraint’

constraint_point = ‘pointConstraint’

constraint_orient = ‘orientConstraint’

constraint_scale = ‘scaleConstraint’

constraint_aim = ‘aimConstraint’

editable_constraints = [‘parentConstraint’, ‘pointConstraint’, ‘orientConstraint’, ‘scaleConstraint’, ‘aimConstraint’]

has_constraint(transform)

get_weight_names(constraint)

get_weight_count(constraint)

Get the number of inputs weights (transforms) feeding int the constraint.

Parameters:constraint (str) – The name of a constraint.

get_constraint(transform, constraint_type)

Find a constraint on the transform.

Parameters:

• transform (str) – The name of a transform that is constrained.
• constraint_type (str) – The type of constraint to search for. Eg. parentConstraint, orientConstraint, pointConstraint, etc.

Retrun

str: The name of the constraint.

get_transform(constraint)

Get the transform that the constraint is constraining.

Parameters:constraint (str) – The name of the constraint. Returns:The name of the transform that is being constrained. Return type:str

get_targets(constraint)

Get the transforms influencing the constraint.

Parameters:constraint (str) – The name of the constraint. Returns:The names of the transforms affecting the constraint. Return type:list

remove_target(target, constraint)

Remove a target from a constraint. This only works if the constraint has all its original connections intact.

Parameters:

• target (str) – The name of the transform target to remove.
• constraint (str) – The name of a constraint that has target affecting it.

set_interpolation(int_value, constraint)

Set the interpolation type of the constraint.

Parameters:

• int_value (int) – index of the interpolation type.
• constraint (str) – The name of a constraint. Probably “parentConstraint” or “orientConstraint”.

create_title(node, constraint, title_name=’FOLLOW’)

This will create a title enum attribute based on the targets feeding into a constraint. The enum will have the name of the transforms affecting the constraint.

Parameters:

• node (str) – The name of the node to add the title to.
• constraint (str) – The name of a constraint. Should be affected by multipe transforms.
• title_name (str) – The name to give the title attribute.

create_switch(node, attribute, constraint)

Create a switch over all the target weights.

Parameters:

• node (str) – The name of the node to add the switch attribute to.
• attribute (str) – The name to give the switch attribute.
• constraint (str) – The name of the constraint with multiple weight target transforms affecting it.
