Method Details

getCollisionObject

public PhysicsCollisionObject getCollisionObject()

Access the collision object that was hit.

Returns:

the pre-existing instance (not null)

getHitFraction

public float getHitFraction()

Return the fraction of the way between the transforms (from=0, to=1, ≥0, ≤1)

Returns:

fraction (from=0, to=1, ≥0, ≤1)

getHitNormalLocal

public Vector3f getHitNormalLocal(Vector3f storeResult)

Copy the normal vector at the point of contact.

Parameters:

storeResult - storage for the result (modified if not null)

Returns:

a unit vector (in physics-space coordinates, either storeResult or a new vector, not null)

partIndex

public int partIndex()

Return the part index at the point of contact.

If shape that was hit is compound or convex, the index is undefined.

If the shape is a GImpactCollisionShape or MeshCollisionShape, the index identifies an IndexedMesh.

If the shape is a HeightfieldCollisionShape, the index identifies a grid row.

Returns:

the index of the collision-shape part (≥0) or -1 if undefined

triangleIndex

public int triangleIndex()

Return the triangle index at the point of contact.

If shape that was hit is convex, the index is undefined.

If shape is a CompoundCollisionShape, the index identifies a child shape.

If the shape is a GImpactCollisionShape or MeshCollisionShape, the index identifies a triangle in an IndexedMesh.

If the shape is a HeightfieldCollisionShape, the index indicates a grid column.

Returns:

the index of the collision-shape triangle (≥0) or -1 if undefined
