Class FABRIK2D
Utility for 2D Forward And Backward Reaching Inverse Kinematics (FABRIK) IK Solver.
Namespace: UnityEngine.U2D.IK
Syntax
public static class FABRIK2D : objectMethods
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. |
