Constructor Detail

IlvRelativeConstraint

public IlvRelativeConstraint(Object lowerNodeOrGroup,
                             Object higherNodeOrGroup,
                             float priority)

Creates a new IlvRelativeConstraint . See IlvRelativeLevelConstraint and IlvRelativePositionConstraint for a detailed description of its purpose.

Parameters:

lowerNodeOrGroup - A node, or a group of IlvNodeGroup objects placed in a lower position than the second node or group.

higherNodeOrGroup - A node, or a group of IlvNodeGroup objects placed in a higher position than the first node or group.

priority - The priority of the constraint.
