Detailed Description

Represents a layer which is rendered on top of the 'normal' scene contents.

Remarks: An overlay is a container for visual components (2D and 3D) which will be rendered after the main scene in order to composite heads-up-displays, menus or other layers on top of the contents of the scene.

: An overlay always takes up the entire size of the viewport, although the components attached to it do not have to. An overlay has no visual element in itself, it it merely a container for visual elements.

: Overlays are created by calling OverlayManager::create, or by defining them in special text scripts (.overlay files). As many overlays as you like can be defined; after creation an overlay is hidden i.e. not visible until you specifically enable it by calling 'show'. This allows you to have multiple overlays predefined (menus etc) which you make visible only when you want. It is possible to have multiple overlays enabled at once; in this case the relative 'zorder' parameter of the overlays determine which one is displayed on top.

: By default overlays are rendered into all viewports. This is fine when you only have fullscreen viewports, but if you have picture-in-picture views, you probably don't want the overlay displayed in the smaller viewports. You turn this off for a specific viewport by calling the Viewport::setDisplayOverlays method.

Gets the bounding Radius scaled by max( scale.x, scale.y, scale.z ).

Remarks: Unlike getWorldRadius, this function guarantees the cache stays up to date. It is STRONGLY advised against calling this function for a large number of MovableObject. Refactor your queries so that they happen after SceneManager::updateAllBounds() has been called

See also: buildLightList

Returns: The list of lights use to lighting this object.

◆ remove2D()

Removes a 2D container from the overlay.

Remarks: NOT FAST. Consider OverlayElement::hide.

◆ removeQueryFlags()

inlineinherited

As setQueryFlags, except the flags passed as parameters are removed from the existing flags on this object.

◆ removeVisibilityFlags()

◆ scroll()

void Ogre::v1::Overlay::scroll	(	Real	xoff,
		Real	yoff
	)

Scrolls the overlay by the offsets provided.

Remarks: This method moves the overlay by the amounts provided. As with other methods on this object, a full screen width / height is represented by the value 1.0.

◆ setCastShadows()

void Ogre::MovableObject::setCastShadows ( bool enabled )

inlineinherited

Sets whether or not this object will cast shadows.

Remarks: This setting simply allows you to turn on/off shadows for a given object. An object will not cast shadows unless the scene supports it in any case (see SceneManager::setShadowTechnique), and also the material which is in use must also have shadow casting enabled. By default all entities cast shadows. If, however, for some reason you wish to disable this for a single object then you can do so using this method.

Note: This method normally refers to objects which block the light, but since Light is also a subclass of MovableObject, in that context it means whether the light causes shadows itself.

◆ setDefaultLightMask()

static void Ogre::MovableObject::setDefaultLightMask ( uint32 mask )

inlinestaticinherited

Set the default light mask for all future MovableObject instances.

◆ setDefaultQueryFlags()

static void Ogre::MovableObject::setDefaultQueryFlags ( uint32 flags )

inlinestaticinherited

Set the default query flags for all future MovableObject instances.

◆ setDefaultVisibilityFlags()

static void Ogre::MovableObject::setDefaultVisibilityFlags ( uint32 flags )

inlinestaticinherited

Set the default visibility flags for all future MovableObject instances.

◆ setLightMask()

void Ogre::MovableObject::setLightMask ( uint32 lightMask )

inlineinherited

Set a bitwise mask which will filter the lights affecting this object.

Remarks: This mask will be compared against the mask held against Light to determine if a light should affect a given object. By default, this mask is fully set meaning all lights will affect this object

◆ setListener()

void Ogre::MovableObject::setListener ( Listener * listener )

inlineinherited

Sets a listener for this object.

Remarks: Note for size and performance reasons only one listener per object is allowed.

◆ setLocalAabb()

void Ogre::MovableObject::setLocalAabb ( const Aabb box )

inherited

Sets the local axis-aligned bounding box for this object.

Remarks: This bounding box is in local coordinates.

◆ setName()

void Ogre::MovableObject::setName ( const String & name )

inlineinherited

Sets a custom name for this node.

Doesn't have to be unique

◆ setQueryFlags()

void Ogre::MovableObject::setQueryFlags ( uint32 flags )

inlineinherited

Sets the query flags for this object.

Remarks: When performing a scene query, this object will be included or excluded according to flags on the object and flags on the query. This is a bitwise value, so only when a bit on these flags is set, will it be included in a query asking for that flag. The meaning of the bits is application-specific.

◆ setRenderingDistance()

void Ogre::MovableObject::setRenderingDistance ( Real dist )

inlineinherited

Sets the distance at which the object is no longer rendered.

Parameters

dist	Distance beyond which the object will not be rendered (the default is FLT_MAX, which means objects are always rendered). Values equal or below zero will be ignored, and cause an assertion in debug mode.

◆ setRenderingMinPixelSize()

void Ogre::MovableObject::setRenderingMinPixelSize ( Real pixelSize )

inlineinherited

Sets the minimum pixel size an object needs to be in both screen axes in order to be rendered.

Note: Camera::setUseMinPixelSize() needs to be called for this parameter to be used.

Parameters

pixelSize Number of minimum pixels (the default is 0, which means objects are always rendered).

◆ setRenderQueueGroup()

virtual void Ogre::MovableObject::setRenderQueueGroup ( uint8 queueID )

virtualinherited

Sets the render queue group this entity will be rendered through.

Remarks: Render queues are grouped to allow you to more tightly control the ordering of rendered objects. If you do not call this method, all Entity objects default to the default queue (RenderQueue::getDefaultQueueGroup), which is fine for most objects. You may want to alter this if you want this entity to always appear in front of other objects, e.g. for a 3D menu system or such.

: See RenderQueue for more details.

Parameters

queueID Enumerated value of the queue group to use. See the enum RenderQueueGroupID for what kind of values can be used here.

: Valid render queue ids are between 0 & 254 inclusive

Reimplemented in Ogre::ParticleSystem, Ogre::Light, Ogre::InternalCubemapProbe, Ogre::v1::Entity, and Ogre::Decal.

◆ setRotate()

void Ogre::v1::Overlay::setRotate ( const Radian & angle )

Sets the rotation applied to this overlay.

◆ setScale()

void Ogre::v1::Overlay::setScale	(	Real	x,
		Real	y
	)

Sets the scaling factor of this overlay.

Remarks: You can use this to set an scale factor to be used to zoom an overlay.

Parameters

x	Horizontal scale value, where 1.0 = normal, 0.5 = half size etc
y	Vertical scale value, where 1.0 = normal, 0.5 = half size etc

◆ setScroll()

void Ogre::v1::Overlay::setScroll	(	Real	x,
		Real	y
	)

Sets the scrolling factor of this overlay.

Remarks: You can use this to set an offset to be used to scroll an overlay around the screen.

Parameters

x	Horizontal scroll value, where 0 = normal, -0.5 = scroll so that only the right half the screen is visible etc
y	Vertical scroll value, where 0 = normal, 0.5 = scroll down by half a screen etc.

◆ setShadowRenderingDistance()

void Ogre::MovableObject::setShadowRenderingDistance ( Real dist )

inlineinherited

Sets the distance at which the object is no longer casting shadows.

Parameters

dist	Distance beyond which the object will not cast shadows (the default is FLT_MAX, which means objects are always casting shadows). Values equal or below zero will be ignored, and cause an assertion in debug mode.

Note: ShadowRenderingDistance will be clamped to RenderingDistance value

See also: setRenderingDistance

◆ setStatic()

bool Ogre::MovableObject::setStatic ( bool bStatic )

inherited

Turns this Node into static or dynamic.

Remarks: Switching between dynamic and static has some overhead and forces to update all static scene when converted to static. So don't do it frequently. Static objects are not updated every frame, only when requested explicitly. Use this feature if you plan to have this object unaltered for a very long times

: Note all MovableObjects support switching between static & dynamic after they have been created (eg. InstancedEntity)

: Changing this attribute will cause to switch the attribute to our parent node, and as a result, all of its other attached entities. @See Node::setStatic

Returns: True if setStatic made an actual change. False otherwise. Can fail because the object was already static/dynamic, or because switching is not supported

◆ setVisibilityFlags()

void Ogre::MovableObject::setVisibilityFlags ( uint32 flags )

inlineinherited

Sets the visibility flags for this object.

Remarks: As well as a simple true/false value for visibility (as seen in setVisible), you can also set visibility flags that is applied a binary 'and' with the SceneManager's mask and a compositor node pass. To exclude particular objects from rendering. Changes to reserved visibility flags are ignored (won't take effect).

◆ setVisible()

void Ogre::MovableObject::setVisible ( bool visible )

inlineinherited

Tells this object whether to be visible or not, if it has a renderable component.

Note: An alternative approach of making an object invisible is to detach it from it's SceneNode, or to remove the SceneNode entirely. Detaching a node means that structurally the scene graph changes. Once this change has taken place, the objects / nodes that have been removed have less overhead to the visibility detection pass than simply making the object invisible, so if you do this and leave the objects out of the tree for a long time, it's faster. However, the act of detaching / reattaching nodes is in itself more expensive than setting an object visibility flag, since in the latter case structural changes are not made. Therefore, small or frequent visibility changes are best done using this method; large or more longer term changes are best done by detaching.

◆ setZOrder()

void Ogre::v1::Overlay::setZOrder ( uint16 zorder )

Alters the Z-order of this overlay.

Remarks: Values between 0 and 2^DepthBits - 1 are valid here. DepthBits is defined in RenderQueue.cpp

◆ show()

void Ogre::v1::Overlay::show ( )

Shows the overlay if it was hidden.

◆ updateAllBounds()

static void Ogre::MovableObject::updateAllBounds	(	const size_t	numNodes,
		ObjectData	t
	)

staticinherited

@See SceneManager::updateAllBounds

Remarks: We don't pass by reference on purpose (avoid implicit aliasing)
