Methods

BeginPlay(SceneBeginData* data)

Called when adding object to the game.

Declaration
protected virtual void BeginPlay(SceneBeginData* data) override
Parameters
SceneBeginData data

The initialization data (e.g. used to collect joints to link after begin).
Overrides

ClearInteria()

Sets the inertia derived from transform change to zero (once). It will reset any cloth object movement effects as it was teleported.

Declaration
public void ClearInteria()

Deserialize(DeserializeStream& stream, ISerializeModifier* modifier)

Deserializes object from the input stream.

Declaration
public virtual void Deserialize(DeserializeStream& stream, ISerializeModifier* modifier) override
Parameters
DeserializeStream stream

The input stream.
ISerializeModifier modifier

The deserialization modifier object. Always valid.
Overrides

Draw(RenderContext& renderContext)

Draws this actor. Called by Scene Rendering service. This call is more optimized than generic Draw (eg. geometry is rendered during all pass types but other actors are drawn only during GBufferFill pass).

Declaration
public virtual void Draw(RenderContext& renderContext) override
Parameters
RenderContext renderContext

The rendering context.
Overrides

Draw(RenderContextBatch& renderContextBatch)

Draws this actor. Called by Scene Rendering service. This call is more optimized than generic Draw (eg. geometry is rendered during all pass types but other actors are drawn only during GBufferFill pass).

Declaration
public virtual void Draw(RenderContextBatch& renderContextBatch) override
Parameters
RenderContextBatch renderContextBatch

The rendering context batch (eg, main view and shadow projections).
Overrides

EndPlay()

Called when removing object from the game.

Declaration
protected virtual void EndPlay() override
Overrides

GetCollision()

Gets the cloth response to collisions settings.

Declaration
public CollisionSettings GetCollision() const
Returns
CollisionSettings

GetFabric()

Gets the cloth's fabric settings (material's stiffness and compression response).

Declaration
public FabricSettings GetFabric() const
Returns
FabricSettings

GetForce()

Gets the cloth response to forces settings.

Declaration
public ForceSettings GetForce() const
Returns
ForceSettings

GetMesh()

Gets the mesh to use for the cloth simulation (single mesh from specific LOD). Always from the parent static or animated model actor.

Declaration
public ModelInstanceActor::MeshReference GetMesh() const
Returns
ModelInstanceActor::MeshReference

GetPaint()

Gets the cloth particles paint data with per-particle max distance (normalized 0-1, 0 makes particle immovable). Returned value is empty if cloth was not initialized or doesn't use paint feature.

Declaration
public Span<float> GetPaint() const
Returns
Span<float>

GetParticles()

Gets the cloth particles data with per-particle XYZ position (in local cloth-space).

Declaration
public Array<Float3> GetParticles() const
Returns
Array<Float3>

GetPhysicsCloth()

Gets the native physics backend object.

Declaration
public void* GetPhysicsCloth() const
Returns
void

GetSimulation()

Gets the cloth simulation settings.

Declaration
public SimulationSettings GetSimulation() const
Returns
SimulationSettings

IntersectsItself(const Ray& ray, Real& distance, Vector3& normal)

Determines if there is an intersection between the current object and a ray.

Declaration
public virtual bool IntersectsItself(const Ray& ray, Real& distance, Vector3& normal) override
Parameters
Ray ray

The ray to test.
Real distance

When the method completes, contains the distance of the intersection (if any valid).
Vector3 normal

When the method completes, contains the intersection surface normal vector (if any valid).
Returns
bool

True whether the two objects intersected, otherwise false.
Overrides

OnDebugDrawSelected()

Draws debug shapes for the selected actor and all child scripts.

Declaration
protected virtual void OnDebugDrawSelected() override
Overrides

OnDeleteObject()

Deletes the object. Called by the ObjectsRemovalService. Can be overriden to provide custom logic per object (cleanup, etc.).

Declaration
protected virtual void OnDeleteObject() override
Overrides

OnDisable()

Called when actor gets removed from game systems. Occurs on EndPlay event or when actor gets inactivated in hierarchy. Use this event to unregister object from other game system (eg. audio).

Declaration
protected virtual void OnDisable() override
Overrides

OnEnable()

Called when actor gets added to game systems. Occurs on BeginPlay event or when actor gets activated in hierarchy. Use this event to register object to other game system (eg. audio).

Declaration
protected virtual void OnEnable() override
Overrides

OnParentChanged()

Called when actor parent gets changed.

Declaration
protected virtual void OnParentChanged() override
Overrides

OnPhysicsSceneChanged(PhysicsScene* previous)

Declaration
protected virtual void OnPhysicsSceneChanged(PhysicsScene* previous) override
Parameters
PhysicsScene previous

Overrides

OnPostUpdate()

Declaration
public void OnPostUpdate()

OnPreUpdate()

Declaration
public bool OnPreUpdate()
Returns
bool

OnTransformChanged()

Called when actor transform gets changed.

Declaration
protected virtual void OnTransformChanged() override
Overrides

Rebuild()

Recreates the cloth by removing current instance data and creating a new physical cloth object.

Declaration
public void Rebuild()

Serialize(SerializeStream& stream, const void* otherObj)

Serializes object to the output stream compared to the values of the other object instance (eg. default class object). If other object is null then serialize all properties.

Declaration
public virtual void Serialize(SerializeStream& stream, const void* otherObj) override
Parameters
SerializeStream stream

The output stream.
void otherObj

The instance of the object to compare with and serialize only the modified properties. If null, then serialize all properties.
