Fixture class
A fixture is used to attach a Shape to a Body for collision detection. A
fixture inherits its transform from its parent. Fixtures hold additional
non-geometric data such as friction, collision filters, etc. Fixtures are
created via body.createFixture.
Do note that you cannot reuse fixtures.

Get the type of the child shape. You can use this to down cast to the
concrete shape.

Methods
-
computeDistance(
Vector2 point, int childIndex, Vector2 normalOut) → double - Compute the distance from this fixture.
-
createProxies(
BroadPhase broadPhase, Transform xf) → void -
destroyProxies(
BroadPhase broadPhase) → void - Internal method
-
getAABB(
int childIndex) → AABB - Get the fixture's AABB. This AABB may be enlarge and/or stale. If you need a more accurate AABB, compute it using the shape and the body transform.
-
getMassData(
MassData massData) → void - Get the mass data for this fixture. The mass data is based on the density and the shape. The rotational inertia is about the shape's origin.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
raycast(
RayCastOutput output, RayCastInput input, int childIndex) → bool - Cast a ray against this shape.
-
refilter(
) → void - Call this if you want to establish collision that was previously disabled by ContactFilter.shouldCollide.
-
render(
DebugDraw debugDraw, Transform xf, Color3i color, bool wireframe) → void -
setSensor(
bool sensor) → void - Set if this fixture is a sensor.
-
synchronize(
BroadPhase broadPhase, Transform transform1, Transform transform2) → void -
testPoint(
Vector2 point) → bool - Test a point for containment in this fixture. This only works for convex shapes.
-
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
