Methods

Solve(Vector2, Int32, Single, Single[], ref Vector2[])

Solve IK based on FABRIK

Declaration

public static bool Solve(Vector2 targetPosition, int solverLimit, float tolerance, float[] lengths, ref Vector2[] positions)

Parameters

Type	Name	Description
Vector2	targetPosition	Target position.
Int32	solverLimit	Solver iteration count.
Single	tolerance	Target position's tolerance.
Single[]	lengths	Length of the chains.
Vector2[]	positions	Chain positions.

Returns

Type	Description
Boolean	Returns true if solver successfully completes within iteration limit. False otherwise.
