class: Fixture

[17:7] extends: FxObj

Wraps jbox2d's Fixture (com.almasb.fxgl.physics.box2d.dynamics.Fixture), the per- shape attachment that lives on a Body. Carries the shape, friction, restitution, density, sensor flag, contact filter, the HitBox it backs, and optional user data.

Methods

Fixture ()

Empty default constructor; populated by adopt.
adopt (object Ajo)

Wraps an existing Fixture AussomJavaObject.
getBody ()

Returns the owning Body AJO.
getShape ()

Returns the Shape AJO.
getType ()

Returns the ShapeType enum AJO.
getFilterData ()

Returns the contact Filter wrapper.
setFilterData (object FilterObj)

Updates the contact Filter from a Filter wrapper.
getDensity ()
setDensity (double V)
getFriction ()
setFriction (double V)
getRestitution ()
setRestitution (double V)
isSensor ()
setSensor (bool V)
getHitBox ()

Returns the backing HitBox wrapper.
setHitBox (object HitBoxObj)
getUserData ()
setUserData (Data)
refilter ()

Forces a contact filter refresh.
containsPoint (object PointVec)

Returns true when the world-point sits inside this fixture's shape.
getProxyCount ()

Returns the count of broad-phase proxies on this fixture (one per child shape for ChainShape; otherwise 1).
getProxyId (int ChildIndex)

Returns the broad-phase proxy id at the given child shape index.
getMassData (object MassDataAjo)

Fills MassDataAjo with the fixture's mass / center / inertia derived from its shape and density. The MassData AJO is populated in place.
getAABB (int ChildIndex)

Returns the world-space AABB AJO for the given child shape index. Use 0 for non-chain shapes.
raycast (object OutputAjo, object InputAjo, int ChildIndex)

Runs a raycast against this fixture, writing into Output.
- @p OutputAjo is a RayCastOutput AJO to populate.
- @p InputAjo is a RayCastInput AJO with the ray parameters.
- @p ChildIndex is the child shape index (0 for non-chain).
- @r true on hit, false otherwise.
computeDistance (object PointVec, int ChildIndex, object NormalOutVec)

Returns the closest world-space distance from PointVec to this fixture for the given child index; writes the closest point on the fixture into NormalOutVec.
