Constructor Detail

CollisionResult

public CollisionResult(Vector contact,
                       Vector trans)

Creates a CollisionResult object describing the result of a collision calculation.

Parameters:

contact - where the collision happened

trans - how much the first shape should be moved

Method Detail

contactPoint

public Vector contactPoint()

Get the location of the contact.

Returns:

the contact point

translation

public Vector translation()

Get the vector that moves the first object out of the collision.

Returns:

the vector that moves the first object out of the collision

invert

public CollisionResult invert()

Get a copy of this with the translation vector inverted. This may be used to make it describe the other object's translation.

Returns:

the modified CollisionResult
