Methods

DoPrepare()

Prepares the data required for updating the solver.

Declaration
protected override void DoPrepare()
Overrides

DoUpdateIK(List<Vector3>)

Updates the IK and sets the chain's transform positions.

Declaration
protected override void DoUpdateIK(List<Vector3> targetPositions)
Parameters
Type Name Description
List<Vector3> targetPositions

Target position for the chain.
Overrides

GetChain(int)

Gets the chain in the solver at index.

Declaration
public override IKChain2D GetChain(int index)
Parameters
Type Name Description
int index

Index to query. Not used in this override.
Returns
Type Description
IKChain2D

Returns IKChain2D for the Solver.
Overrides

GetChainCount()

Returns the number of chains in the solver.

Declaration
protected override int GetChainCount()
Returns
Type Description
int

Returns 1, because FABRIK Solver has only one chain.
