◆ setMaterial()

void Ogre::OverlayElement::setMaterial ( const MaterialPtr & mat )

inherited

Sets the the material this element will use.

Remarks: Different elements will use different materials. One constant about them all though is that a Material used for a OverlayElement must have it's depth checking set to 'off', which means it always gets rendered on top. OGRE will set this flag for you if necessary. What it does mean though is that you should not use the same Material for rendering OverlayElements as standard scene objects. It's fine to use the same textures, just not the same Material.

◆ setMaterialName()

void Ogre::OverlayElement::setMaterialName ( const String & matName )

inherited

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Reimplemented in Ogre::OverlayContainer.

◆ _updateFromParent()

virtual void Ogre::OverlayElement::_updateFromParent ( void )

virtualinherited

Updates this elements transform based on it's parent.

◆ _notifyParent()

virtual void Ogre::OverlayElement::_notifyParent	(	OverlayContainer *	parent,
		Overlay *	overlay
	)

virtualinherited

Internal method for notifying the GUI element of it's parent and ultimate overlay.

Reimplemented in Ogre::OverlayContainer.

◆ _getDerivedLeft()

virtual Real Ogre::OverlayElement::_getDerivedLeft ( void )

virtualinherited

Gets the 'left' position as derived from own left and that of parents.

◆ _getDerivedTop()

virtualinherited

Gets the clipping region of the element.

◆ _notifyZOrder()

virtual ushort Ogre::OverlayElement::_notifyZOrder ( ushort newZOrder )

virtualinherited

Internal method to notify the element when Z-order of parent overlay has changed.

Remarks: Overlays have explicit Z-orders. OverlayElements do not, they inherit the Z-order of the overlay, and the Z-order is incremented for every container nested within this to ensure that containers are displayed behind contained items. This method is used internally to notify the element of a change in final Z-order which is used to render the element.

Returns: Return the next Z-ordering number available. For single elements, this is simply 'newZOrder + 1', except for containers. They increment it once for each child (or even more if those children are also containers with their own elements).

Reimplemented in Ogre::OverlayContainer.

◆ _notifyWorldTransforms()

virtual void Ogre::OverlayElement::_notifyWorldTransforms ( const Matrix4 & xform )

virtualinherited

Internal method to notify the element when it's world transform of parent overlay has changed.

Reimplemented in Ogre::OverlayContainer.

virtualinherited

Internal method to notify the element when the viewport of parent overlay has changed.

Reimplemented in Ogre::OverlayContainer.

◆ _updateRenderQueue()

virtual void Ogre::OverlayElement::_updateRenderQueue ( RenderQueue * queue )

virtualinherited

Internal method to put the contents onto the render queue.

Reimplemented in Ogre::BorderPanelOverlayElement, Ogre::OverlayContainer, and Ogre::PanelOverlayElement.

◆ visitRenderables()

void Ogre::OverlayElement::visitRenderables	(	Renderable::Visitor *	visitor,
		bool	debugRenderables = `false`
	)

inherited

Method to allow a caller to abstractly iterate over the Renderable instances that this MovableObject will add to the render queue when asked, if any.

Parameters

visitor	Pointer to a class implementing the Renderable::Visitor interface which will be called back for each Renderable which will be queued. Bear in mind that the state of the Renderable instances may not be finalised depending on when you call this.
debugRenderables	If false, only regular renderables will be visited (those for normal display). If true, debug renderables will be included too.

◆ getCaption()

virtual const DisplayString& Ogre::OverlayElement::getCaption ( void ) const

virtualinherited

Gets the caption for this element.

◆ getMetricsMode()

virtual GuiMetricsMode Ogre::OverlayElement::getMetricsMode ( void ) const

virtualinherited

Retrieves the current settings of how the element metrics are interpreted.

◆ setHorizontalAlignment()

virtual void Ogre::OverlayElement::setHorizontalAlignment ( GuiHorizontalAlignment gha )

virtualinherited

Sets the horizontal origin for this element.

Remarks: By default, the horizontal origin for a OverlayElement is the left edge of the parent container (or the screen if this is a root element). You can alter this by calling this method, which is especially useful when you want to use pixel-based metrics (see setMetricsMode) since in this mode you can't use relative positioning.

: For example, if you were using GMM_PIXELS metrics mode, and you wanted to place a 30x30 pixel crosshair in the center of the screen, you would use GHA_CENTER with a 'left' property of -15.

: Note that neither GHA_CENTER or GHA_RIGHT alter the position of the element based on it's width, you have to alter the 'left' to a negative number to do that; all this does is establish the origin. This is because this way you can align multiple things in the center and right with different 'left' offsets for maximum flexibility.

◆ getHorizontalAlignment()

virtual GuiHorizontalAlignment Ogre::OverlayElement::getHorizontalAlignment ( void ) const

virtualinherited

Gets the horizontal alignment for this element.

◆ setVerticalAlignment()

virtual void Ogre::OverlayElement::setVerticalAlignment ( GuiVerticalAlignment gva )

virtualinherited

Sets the vertical origin for this element.

Remarks: By default, the vertical origin for a OverlayElement is the top edge of the parent container (or the screen if this is a root element). You can alter this by calling this method, which is especially useful when you want to use pixel-based metrics (see setMetricsMode) since in this mode you can't use relative positioning.

: For example, if you were using GMM_PIXELS metrics mode, and you wanted to place a 30x30 pixel crosshair in the center of the screen, you would use GHA_CENTER with a 'top' property of -15.

: Note that neither GVA_CENTER or GVA_BOTTOM alter the position of the element based on it's height, you have to alter the 'top' to a negative number to do that; all this does is establish the origin. This is because this way you can align multiple things in the center and bottom with different 'top' offsets for maximum flexibility.

Returns: A reference to a static list of ParameterDef objects.

◆ setParameter()

bool Ogre::StringInterface::setParameter	(	const String &	name,
		const String &	value
	)

inherited

Generic parameter setting method.

Remarks: Call this method with the name of a parameter and a string version of the value to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

name	The name of the parameter to set
value	String value. Must be in the right format for the type specified in the parameter definition. See the StringConverter class for more information.

Returns: true if set was successful, false otherwise (NB no exceptions thrown - tolerant method)

Referenced by Ogre::StringInterface::copyParametersTo().

◆ setParameterList()

void Ogre::StringInterface::setParameterList ( const NameValuePairList & paramList )

inherited

Generic multiple parameter setting method.

Remarks: Call this method with a list of name / value pairs to set. The implementor will convert the string to a native type internally. If in doubt, check the parameter definition in the list returned from StringInterface::getParameters.

Parameters

paramList Name/value pair list

◆ getParameter()

String Ogre::StringInterface::getParameter ( const String & name ) const

inlineinherited

Generic parameter retrieval method.

Remarks: Call this method with the name of a parameter to retrieve a string-format value of the parameter in question. If in doubt, check the parameter definition in the list returned from getParameters for the type of this parameter. If you like you can use StringConverter to convert this string back into a native type.

Parameters

name	The name of the parameter to get

Returns: String value of parameter, blank if not found

References Ogre::ParamCommand::doGet().

◆ copyParametersTo()

void Ogre::StringInterface::copyParametersTo ( StringInterface * dest ) const

inlineinherited

Method for copying this object's parameters to another object.

Remarks: This method takes the values of all the object's parameters and tries to set the same values on the destination object. This provides a completely type independent way to copy parameters to other objects. Note that because of the String manipulation involved, this should not be regarded as an efficient process and should be saved for times outside of the rendering loop.

: Any unrecognised parameters will be ignored as with setParameter method.

Parameters

dest	Pointer to object to have it's parameters set the same as this object.

References Ogre::StringInterface::setParameter().

◆ cleanupDictionary()

static void Ogre::StringInterface::cleanupDictionary ( )

staticinherited

Cleans up the static 'msDictionary' required to reset Ogre, otherwise the containers are left with invalid pointers, which will lead to a crash as soon as one of the ResourceManager implementers (e.g.

MaterialManager) initializes.

◆ getTechnique()

virtual Technique* Ogre::Renderable::getTechnique ( void ) const

inlinevirtualinherited

Retrieves a pointer to the Material Technique this renderable object uses.

Remarks: This is to allow Renderables to use a chosen Technique if they wish, otherwise they will use the best Technique available for the Material they are using.

Reimplemented in Ogre::InstanceBatch, Ogre::InstancedGeometry::GeometryBucket, Ogre::StaticGeometry::GeometryBucket, and Ogre::SubEntity.

◆ preRender()

virtual bool Ogre::Renderable::preRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)

inlinevirtualinherited

Called just prior to the Renderable being rendered.

Remarks: OGRE is a queued renderer, so the actual render commands are executed at a later time than the point at which an object is discovered to be visible. This allows ordering & grouping of renders without the discovery process having to be aware of it. It also means OGRE uses declarative render information rather than immediate mode rendering - this is very useful in that certain effects and processes can automatically be applied to a wide range of scenes, but the downside is that special cases are more difficult to handle, because there is not the declared state to cope with it.

: This method allows a Renderable to do something special at the actual point of rendering if it wishes to. When this method is called, all the material render state as declared by this Renderable has already been set, all that is left to do is to bind the buffers and perform the render. The Renderable may modify render state itself if it wants to (and restore it in the postRender call) before the automated render happens, or by returning 'false' from this method can actually suppress the automatic render and perform one of its own.

Returns: true if the automatic render should proceed, false to skip it on the assumption that the Renderable has done it manually.

Reimplemented in Ogre::BillboardChain.

◆ postRender()

virtual void Ogre::Renderable::postRender	(	SceneManager *	sm,
		RenderSystem *	rsys
	)

inlinevirtualinherited

Called immediately after the Renderable has been rendered.

◆ getNumWorldTransforms()

virtual unsigned short Ogre::Renderable::getNumWorldTransforms ( void ) const

inlinevirtualinherited

Returns the number of world transform matrices this renderable requires.

Remarks: When a renderable uses vertex blending, it uses multiple world matrices instead of a single one. Each vertex sent to the pipeline can reference one or more matrices in this list with given weights. If a renderable does not use vertex blending this method returns 1, which is the default for simplicity.

Reimplemented in Ogre::BorderRenderable, Ogre::SubEntity, Ogre::InstancedGeometry::GeometryBucket, Ogre::BaseInstanceBatchVTF, Ogre::InstanceBatchHW, and Ogre::InstanceBatchShader.

◆ setUseIdentityProjection()

void Ogre::Renderable::setUseIdentityProjection ( bool useIdentityProjection )

inlineinherited

Sets whether or not to use an 'identity' projection.

Remarks: Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also: Renderable::getUseIdentityProjection

◆ getUseIdentityProjection()

bool Ogre::Renderable::getUseIdentityProjection ( void ) const

inlineinherited

Returns whether or not to use an 'identity' projection.

Remarks: Usually Renderable objects will use a projection matrix as determined by the active camera. However, if they want they can cancel this out and use an identity projection, which effectively projects in 2D using a {-1, 1} view space. Useful for overlay rendering. Normal renderables need not change this.

See also: Renderable::setUseIdentityProjection

◆ setUseIdentityView()

void Ogre::Renderable::setUseIdentityView ( bool useIdentityView )

inlineinherited

Sets whether or not to use an 'identity' view.

Remarks: Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this. The default is false.

See also: Renderable::getUseIdentityView

◆ getUseIdentityView()

bool Ogre::Renderable::getUseIdentityView ( void ) const

inlineinherited

Returns whether or not to use an 'identity' view.

Remarks: Usually Renderable objects will use a view matrix as determined by the active camera. However, if they want they can cancel this out and use an identity matrix, which means all geometry is assumed to be relative to camera space already. Useful for overlay rendering. Normal renderables need not change this.

See also: Renderable::setUseIdentityView

◆ getCastsShadows()

virtual bool Ogre::Renderable::getCastsShadows ( void ) const

inlinevirtualinherited

Method which reports whether this renderable would normally cast a shadow.

Remarks: Subclasses should override this if they could have been used to generate a shadow.

Reimplemented in Ogre::SubEntity, Ogre::InstancedGeometry::GeometryBucket, and Ogre::StaticGeometry::GeometryBucket.

◆ setCustomParameter()

void Ogre::Renderable::setCustomParameter	(	size_t	index,
		const Vector4 &	value
	)

inlineinherited

Sets a custom parameter for this Renderable, which may be used to drive calculations for this specific Renderable, like GPU program parameters.

Remarks: Calling this method simply associates a numeric index with a 4-dimensional value for this specific Renderable. This is most useful if the material which this Renderable uses a vertex or fragment program, and has an ACT_CUSTOM parameter entry. This parameter entry can refer to the index you specify as part of this call, thereby mapping a custom parameter for this renderable to a program parameter.

Parameters

index	The index with which to associate the value. Note that this does not have to start at 0, and can include gaps. It also has no direct correlation with a GPU program parameter index - the mapping between the two is performed by the ACT_CUSTOM entry, if that is used.
value	The value to associate.

◆ removeCustomParameter()

void Ogre::Renderable::removeCustomParameter ( size_t index )

inlineinherited

Removes a custom value which is associated with this Renderable at the given index.

Parameters

index Index of the parameter to remove.

See also: setCustomParameter for full details.

◆ hasCustomParameter()

bool Ogre::Renderable::hasCustomParameter ( size_t index ) const

inlineinherited

Checks whether a custom value is associated with this Renderable at the given index.

Parameters

index Index of the parameter to check for existence.

See also: setCustomParameter for full details.

◆ getCustomParameter()

const Vector4& Ogre::Renderable::getCustomParameter ( size_t index ) const

inlineinherited

Gets the custom value associated with this Renderable at the given index.

Parameters

index Index of the parameter to retrieve.

See also: setCustomParameter for full details.

References Ogre::Exception::ERR_ITEM_NOT_FOUND, and OGRE_EXCEPT.

◆ _updateCustomGpuParameter()

virtual void Ogre::Renderable::_updateCustomGpuParameter	(	const GpuProgramParameters::AutoConstantEntry &	constantEntry,
		GpuProgramParameters *	params
	)		const

inlinevirtualinherited

Update a custom GpuProgramParameters constant which is derived from information only this Renderable knows.

Remarks: This method allows a Renderable to map in a custom GPU program parameter based on it's own data. This is represented by a GPU auto parameter of ACT_CUSTOM, and to allow there to be more than one of these per Renderable, the 'data' field on the auto parameter will identify which parameter is being updated. The implementation of this method must identify the parameter being updated, and call a 'setConstant' method on the passed in GpuProgramParameters object, using the details provided in the incoming auto constant setting to identify the index at which to set the parameter.

: You do not need to override this method if you're using the standard sets of data associated with the Renderable as provided by setCustomParameter and getCustomParameter. By default, the implementation will map from the value indexed by the 'constantEntry.data' parameter to a value previously set by setCustomParameter. But custom Renderables are free to override this if they want, in any case.

Parameters

constantEntry	The auto constant entry referring to the parameter being updated
params	The parameters object which this method should call to set the updated parameters.

Reimplemented in Ogre::SubEntity.
