Class b2Segment

constructor

• new b2Segment(): b2Segment

• Returns b2Segment

p1

p2

Extend

• Extend(aabb: b2AABB): void

• Extends or clips the segment so that it's ends lie on the boundary of the AABB.

  Parameters

  • aabb: b2AABB

    AABB to extend/clip the segement.

  Returns void

ExtendBackward

• ExtendBackward(aabb: b2AABB): void

• See Extend, this works on the ending point.

  Parameters

  • aabb: b2AABB

    AABB to extend/clip the ending point.

  Returns void

ExtendForward

• ExtendForward(aabb: b2AABB): void

• See Extend, this works on the starting point.

  Parameters

  • aabb: b2AABB

    AABB to extend/clip the starting point.

  Returns void

TestSegment

• TestSegment(
      lambda: number[],
      normal: b2Vec2,
      segment: b2Segment,
      maxLambda: number,
  ): boolean

• Ray cast against this segment with another segment.

  Parameters

  • lambda: number[]

    returns the hit fraction. You can use this to compute the contact point * p = (1 - lambda) * segment.p1 + lambda * segment.p2 *
  • normal: b2Vec2
  • segment: b2Segment

    Defines the begining and end point of the ray cast.
  • maxLambda: number

    a number typically in the range [0,1].

  Returns boolean

  True if there is an intersection, otherwise false.

  Normal

  Normal at the contact point. If there is no intersection, the normal is not set.
