Data

Name Description Default value
name object name unnamed
printLog if true, emits extra messages at runtime. 0
tags list of the subsets the objet belongs to
bbox this object bounding box
componentState The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). Undefined
listening if true, handle the events, otherwise ignore the events 0
group ID of the group containing this constraint. This ID is used to specify which constraints are solved by which solver, by specifying in each solver which groups of constraints it should handle. 0
constraintIndex Constraint index (first index in the right hand term resolution vector) 0
endTime The SoftRobotsConstraint stops acting after the given value. Use a negative value for infinite SoftRobotsConstraints -1
index Index of the node subjected to the force. If no index given, first node of mechanical context considered.
force Output force. Warning: to get the actual force you should divide this value by dt. 0
displacement Output displacement compared to the initial position. 0
maxForce Maximum force allowed. If unspecified no maximum value will be considered.
minForce Minimum force allowed. If unspecified no minimum value will be considered.
maxDisplacement Maximum displacement. If unspecified no maximum value will be considered.
minDisplacement Minimum displacement. If unspecified no minimum value will be considered.
value Displacement or force to impose.
valueType displacement = the constraint will impose the displacement provided in data value[valueIndex] force = the constraint will impose the force provided in data value[valueIndex] If unspecified, the default value is displacement displacement
Name Description Destination type name
context Graph Node containing this object (or BaseContext::getDefault() if no graph is used) BaseContext
slaves Sub-objects used internally by this object BaseObject
master nullptr for regular objects, or master object for which this object is one sub-objects BaseObject
