Detailed Description

Defines an instance of a discrete, movable object based on a Mesh.

Remarks: Ogre generally divides renderable objects into 2 groups, discrete (separate) and relatively small objects which move around the world, and large, sprawling geometry which makes up generally immovable scenery, aka 'level geometry'.

: The Mesh and SubMesh classes deal with the definition of the geometry used by discrete movable objects. Entities are actual instances of objects based on this geometry in the world. Therefore there is usually a single set Mesh for a car, but there may be multiple entities based on it in the world. Entities are able to override aspects of the Mesh it is defined by, such as changing material properties per instance (so you can have many cars using the same geometry but different textures for example). Because a Mesh is split into SubMeshes for this purpose, the Item class is a grouping class (much like the Mesh class) and much of the detail regarding individual changes is kept in the SubItem class. There is a 1:1 relationship between SubItem instances and the SubMesh instances associated with the Mesh the Item is based on.

: Item and SubItem classes are never created directly. Use the createItem method of the SceneManager (passing a model name) to create one.

: Entities are included in the scene by associating them with a SceneNode, using the attachItem method. See the SceneNode class for full information.

Note: No functions were declared virtual to improve performance.

Constructor & Destructor Documentation

◆ ~Item()

Ogre::Item::~Item ( )

override

Default destructor.

Member Function Documentation

◆ _deinitialise()

void Ogre::Item::_deinitialise ( )

Tear down the internal structures of this Item, rendering it uninitialised.

◆ _initialise()

void Ogre::Item::_initialise	(	bool	forceReinitialise = `false`,
		bool	bUseMeshMat = `true`
	)

Try to initialise the Item from the underlying resources.

Remarks: This method builds the internal structures of the Item based on it resources (Mesh, Skeleton). This may or may not succeed if the resources it references have been earmarked for background loading, so you should check isInitialised afterwards to see if it was successful.

Parameters

forceReinitialise If true, this forces the Item to tear down it's internal structures and try to rebuild them. Useful if you changed the content of a Mesh or Skeleton at runtime.

◆ _notifyParentNodeMemoryChanged()

void Ogre::Item::_notifyParentNodeMemoryChanged ( )

overridevirtual

See also: Node::_callMemoryChangeListeners

Reimplemented from Ogre::MovableObject.

◆ getMesh()

const MeshPtr& Ogre::Item::getMesh ( ) const

Gets the Mesh that this Item is based on.

◆ getMovableType()

const String& Ogre::Item::getMovableType ( ) const

overridevirtual

Returns the type name of this object.

Implements Ogre::MovableObject.

◆ getNumSubItems()

size_t Ogre::Item::getNumSubItems ( ) const

Retrieves the number of SubItem objects making up this Item.

◆ getSubItem() [1/2]

SubItem* Ogre::Item::getSubItem ( size_t index )

Gets a pointer to a SubItem, ie a part of an Item.

◆ getSubItem() [2/2]

const SubItem* Ogre::Item::getSubItem ( size_t index ) const

◆ hasSkeleton()

bool Ogre::Item::hasSkeleton ( ) const

inline

Returns whether or not this Item is skeletally animated.

◆ isInitialised()

bool Ogre::Item::isInitialised ( ) const

inline

Returns whether or not this Item is either morph or pose animated.

Returns a pointer to the set of entities which share a OldSkeletonInstance. If this instance does not share it's OldSkeletonInstance with other instances NULL will be returned Has this Item been initialised yet?

Remarks: If this returns false, it means this Item hasn't been completely constructed yet from the underlying resources (Mesh, Skeleton), which probably means they were delay-loaded and aren't available yet. This Item won't render until it has been successfully initialised, nor will many of the manipulation methods function.

◆ loadingComplete()

void Ogre::Item::loadingComplete ( Resource * res )

overridevirtual

Resource::Listener hook to notify Entity that a Mesh is (re)loaded.

Reimplemented from Ogre::Resource::Listener.

◆ setDatablock() [1/2]

void Ogre::Item::setDatablock ( HlmsDatablock * datablock )

Sets the given HLMS databloock to all SubEntities.

◆ setDatablock() [2/2]

void Ogre::Item::setDatablock ( IdString datablockName )

Sets the given HLMS datablock to all SubEntities.

◆ setDatablockOrMaterialName()

void Ogre::Item::setDatablockOrMaterialName	(	const String &	name,
		const String &	groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME`
	)

Sets the material to use for the whole of this Item.

Remarks: This is a shortcut method to set all the materials for all subentities of this Item. Only use this method is you want to set the same material for all subentities or if you know there is only one. Otherwise call getSubItem() and call the same method on the individual SubItem.

◆ setMaterial()

void Ogre::Item::setMaterial ( const MaterialPtr & material )

Sets the material to use for the whole of this Item.

Remarks: This is a shortcut method to set all the materials for all subentities of this Item. Only use this method is you want to set the same material for all subentities or if you know there is only one. Otherwise call getSubItem() and call the same method on the individual SubItem.

◆ setMaterialName()

void Ogre::Item::setMaterialName	(	const String &	name,
		const String &	groupName = `ResourceGroupManager::AUTODETECT_RESOURCE_GROUP_NAME`
	)

Sets the material to use for the whole of this Item.

Remarks: This is a shortcut method to set all the materials for all subentities of this Item. Only use this method is you want to set the same material for all subentities or if you know there is only one. Otherwise call getSubItem() and call the same method on the individual SubItem.

◆ setSkeletonEnabled()

void Ogre::Item::setSkeletonEnabled ( bool bEnable )

Enables or disables the skeleton on this Item and all of its SubItems.

Remarks: Does nothing if the Mesh does not have skeletons.

sharesSkeletonInstance() must be false when calling this function

Some meshes only look correct when there is an active skeleton holding all the vertices in place. Hence force-disabling the skeleton may cause the Item to disappear or look wrong. That depends on how the mesh was modelled and rigged.

Force-disabling a skeleton may result in further shader recompiles, but may help a lot with mobile performance.

It's not 100% the same as a Mesh without skeleton, because we still waste VRAM and Bandwidth in VES_BLEND_WEIGHTS & VES_BLEND_INDICES semantics. However the instruction length of the vertex shader is much lower and no CPU cycles are wasted on updating the skeleton.

Parameters

bEnable True to re-enable the skeleton on this Item. False to force-disable the skeleton on this Item.

◆ sharesSkeletonInstance()

bool Ogre::Item::sharesSkeletonInstance ( ) const

Returns whether this Item shares it's SkeltonInstance with other Item instances.

◆ stopUsingSkeletonInstanceFromMaster()

void Ogre::Item::stopUsingSkeletonInstanceFromMaster ( )

Stops sharing the SkeletonInstance with other Items.

See also: useSkeletonInstanceFrom

◆ useSkeletonInstanceFrom()

void Ogre::Item::useSkeletonInstanceFrom ( Item * master )

Starts using the SkeletonInstance from 'master' instead of using our own.

Useful when multiple Items can use exactly the same skeleton (e.g. on RPG games the master could be the player's character, then the clothes, and armor the slaves sharing the skeleton instance with its master)

Remarks: Calling armour->useSkeletonInstanceFrom( player ); armour->useSkeletonInstanceFrom( newPlayer );

is valid and more efficient than calling: armour->useSkeletonInstanceFrom( player ); armour->stopUsingSkeletonInstanceFromMaster(); armour->useSkeletonInstanceFrom( newPlayer );

: Due to the nature of skeleton sharing, all slaves will end up in the position of the master. Therefore it is highly recommended you attach the slaves and master to the same SceneNode, or that you keep all SceneNodes' transforms in sync. Failure to do so could cause Ogre to cull some of those objects because it thinks they're located somewhere else.
