Detailed Description

Simple wrapper class for constraints.

A unified wrapper around the various constraints that are available in 3ds Max. There is access to the type of constraint in use, plus easier access to the constraints. If further access it needed, the IPropertyContainer interface can be used and additions made to property file used to access other data, as the source for these constraints is available in the SDK.

Member Function Documentation

virtual int NumberOfConstraintNodes ( ) [pure virtual]

Search for all occurrences

Number of constraining Node.

The number of nodes in use by the Constraint system

Returns:: The number of nodes

virtual IGameNode* GetConstraintNodes ( int index ) [pure virtual]

Search for all occurrences

Get the constraint Node.

The actual node of the index passed in that is working in the system

Parameters:

index The index of the node to retrieve

Returns:: A pointer to IGameNode

virtual float GetConstraintWeight ( int nodeIndex ) [pure virtual]

Search for all occurrences

Get the influence of the bone.

This is the weight, or influence the specified node has in the constraint system. The index used here is the same as the index used in IGameConstraint::GetConstraintNodes, otherwise the weights will not match. This has no effect for a Link Constraint

Parameters:

nodeIndex The node index to query

Returns:: The weight value

virtual int GetLinkConstBeginFrame ( int index ) [pure virtual]

Search for all occurrences

Get the start frame for the Link constraint.

This specifies when the link for the n'th node will start.

Parameters:

index The node index

Returns:: The start frame for the node queried.

virtual ConstraintType GetConstraintType ( ) [pure virtual]

Search for all occurrences

Get the type of Constraint.

This defines the actual constraint being used on the controller

Returns:: The type of max constraint. It can be one ConstraintType enum
