    getAnchorPoints()
    Returns all non-tangent ("node") points in order from start to end.
    double
    getDistanceAtTime(double time)
    Returns the approximate arc-length distance (in blocks) along the path at the given time parameter (0..1) of lerp(double).
    double
    getNormalizedDistanceAtTime(double time)
    Returns the normalized arc-length distance (0..1) along the path at the given time parameter (0..1) of lerp(double).

    Invalidates the LUT cache, forcing recalculation on next use.
    boolean
    isPointFirstOrLast(BezierPoint point)
    Checks if a point is at the start or end of the path.
    boolean
    isSinglePoint()

    • isSinglePoint

      public boolean isSinglePoint()
      Returns true if the path consists of a single point with no spline.

    • withPlayerOrigin

      public BezierPath withPlayerOrigin(net.minecraft.world.entity.player.Player player)
      Creates a new path with the player's eye position as the starting point.

    • withPlayerEnd

      public BezierPath withPlayerEnd(net.minecraft.world.entity.player.Player player)
      Creates a new path with the player's eye position as the ending point.

    • updateLUT

      public void updateLUT()
      Updates the Look-Up Table (LUT) for arc-length parameterization. This should be called whenever any point on the path changes.

    • getDistanceAtTime

      public double getDistanceAtTime(double time)
      Returns the approximate arc-length distance (in blocks) along the path at the given time parameter (0..1) of lerp(double). This is derived from the same LUT used for constant-speed motion.

    • getNormalizedDistanceAtTime

      public double getNormalizedDistanceAtTime(double time)
      Returns the normalized arc-length distance (0..1) along the path at the given time parameter (0..1) of lerp(double).

    • lerpSpeedWeighted

      public net.minecraft.world.phys.Vec3 lerpSpeedWeighted(double t)
      Interpolates a position using arc-length parameterization. This provides constant-speed motion along the path.
      Parameter:
      t - parameter from 0 to 1 representing distance along the path

    • getPoints

      public ArrayList<BezierPoint> getPoints()
      Gets all control points in the path.

    • getAnchorPoints
