Detailed Description

OverlayElement representing a flat, single-material (or transparent) panel which can contain other elements.

Remarks

This class subclasses OverlayContainer because it can contain other elements. Like other containers, if hidden it's contents are also hidden, if moved it's contents also move etc. The panel itself is a 2D rectangle which is either completely transparent, or is rendered with a single material. The texture(s) on the panel can be tiled depending on your requirements.

This component is suitable for backgrounds and grouping other elements. Note that because it has a single repeating material it cannot have a discrete border (unless the texture has one and the texture is tiled only once). For a bordered panel, see it's subclass BorderPanelOverlayElement.

Note that the material can have all the usual effects applied to it like multiple texture layers, scrolling / animated textures etc. For multiple texture layers, you have to set the tiling level for each layer.

Remarks

Do not attempt to render a Renderable whose datablock has been set to null. It will crash. You can call setDatablock afterwards though. Use at your own risk, hence the _underscore. See http://ogre3d.org/forums/viewtopic.php?f=25&t=91791&p=534476#p534476

_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::v1::SubEntity.

virtualinherited

Reimplemented from Ogre::v1::OverlayElement.

copyParametersTo()

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

inlinevirtualinherited

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.

findElementAt()

virtual OverlayElement * Ogre::v1::OverlayContainer::findElementAt ( Real  x, Real  y  )

getMetricsMode()

virtual GuiMetricsMode Ogre::v1::OverlayElement::getMetricsMode ( void  ) const

virtualinherited

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

getName()

const String & Ogre::v1::OverlayElement::getName ( void  ) const

getNumPoses()

unsigned short Ogre::Renderable::getNumPoses ( void  ) const

inherited

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::v1::BorderPanelOverlayElement.

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

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

getUseIdentityViewProjMatrixIsDynamic()

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

inlinevirtualinherited

Returns whether the Hlms implementation should evaluate getUseIdentityProjection per object at runtime, or if it can assume the Renderable will remain with the same setting until the datablock is flushed (performance optimization)

Remarks

Hlms implementations may ignore this setting (e.g. assume always true or always false) or even not support identity matrix overrides at all. For example currently Unlit supports them all, but will assume this returns always true if getUseIdentityWorldMatrix returns false.

getUseIdentityWorldMatrix()

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

inlinevirtualinherited

Returns whether the world matrix is an identity matrix.

Remarks

It is up to the Hlms implementation whether to honour this request. Take in mind changes of this value at runtime may not be seen until the datablock is flushed. It is implemented as a virtual call because this functionality isn't required very often (hence we save per-Renderable space for those that don't use it) and this function will be called at creation time to use a different shader; not during rendering time per Renderable.

postRender()

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

inlinevirtualinherited

Called immediately after the Renderable has been rendered.

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::v1::BillboardChain.

removeChild()

virtual void Ogre::v1::OverlayContainer::removeChild ( const String &  name )

Removes a named element from this container.

removeCustomParameter()

setCaption()

virtual void Ogre::v1::OverlayElement::setCaption ( const DisplayString &  text )

virtualinherited

Sets the caption on elements that support it.

Remarks

This property doesn't do something on all elements, just those that support it. However, being a common requirement it is in the top-level interface to avoid having to set it via the StringInterface all the time.

Reimplemented in Ogre::v1::TextAreaOverlayElement.

setChildrenProcessEvents()

virtual void Ogre::v1::OverlayContainer::setChildrenProcessEvents ( bool  val )

Reimplemented in Ogre::v1::TextAreaOverlayElement.

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.

setDatablock() [1/2]

virtual void Ogre::Renderable::setDatablock ( HlmsDatablock *  datablock )

virtualinherited

Assigns a datablock (i.e. HLMS Material) to this renderable.

Reimplemented in Ogre::v1::BillboardSet, Ogre::v1::SubEntity, and Ogre::v1::SubEntity.

setDatablock() [2/2]

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

inherited

Assigns a datablock (i.e.

HLMS material) based on its unique name.

Remarks

An null IdString() is valid, it will use the default material

setDatablockOrMaterialName()

void Ogre::Renderable::setDatablockOrMaterialName ( String  materialName, String  groupName  )

inherited

First tries to see if an HLMS datablock exist with the given name, if not, tries to search among low level materials.

setDimensions()

void Ogre::v1::OverlayElement::setDimensions ( Real  width, Real  height  )

inherited

Sets the dimensions of this element in relation to the screen (1.0 = screen width/height).

setEnabled()

virtual void Ogre::v1::OverlayElement::setEnabled ( bool  b )

virtualinherited

setHeight()

void Ogre::v1::OverlayElement::setHeight ( Real  height )

inherited

Sets the height of this element in relation to the screen (where 1.0 = screen height)

setHorizontalAlignment()

virtual void Ogre::v1::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.

setLeft()

void Ogre::v1::OverlayElement::setLeft ( Real  left )

inherited

Sets the left of this element in relation to the screen (where 0 = far left, 1.0 = far right)

setMaterial()

virtual void Ogre::Renderable::setMaterial ( const MaterialPtr &  material )

virtualinherited

Sets the given material. Overrides HLMS materials.

Reimplemented in Ogre::v1::SimpleRenderable, Ogre::v1::BillboardSet, and Ogre::v1::SubEntity.

setMaterialName() [1/2]

void Ogre::v1::PanelOverlayElement::setMaterialName ( const String &  matName )

virtual

Overridden from OverlayElement.

Reimplemented from Ogre::v1::OverlayElement.

setMaterialName() [2/2]

void Ogre::Renderable::setMaterialName ( const String &  name, const String &  groupName  )

inherited

Sets the name of the Material to be used. Prefer using HLMS @See setHlms.

setMetricsMode()

virtual void Ogre::v1::OverlayElement::setMetricsMode ( GuiMetricsMode  gmm )

virtualinherited

Tells this element how to interpret the position and dimension values it is given.

Remarks

By default, OverlayElements are positioned and sized according to relative dimensions of the screen. This is to ensure portability between different resolutions when you want things to be positioned and sized the same way across all resolutions. However, sometimes you want things to be sized according to fixed pixels. In order to do this, you can call this method with the parameter GMM_PIXELS. Note that if you then want to place your element relative to the center, right or bottom of it's parent, you will need to use the setHorizontalAlignment and setVerticalAlignment methods.

Reimplemented in Ogre::v1::BorderPanelOverlayElement, and Ogre::v1::TextAreaOverlayElement.

setParameter()

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

virtualinherited

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)

setParameterList()

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

virtualinherited

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

setPolygonModeOverrideable()

virtual void Ogre::Renderable::setPolygonModeOverrideable ( bool  override )

inlinevirtualinherited

Sets whether this renderable's chosen detail level can be overridden (downgraded) by the camera setting.

Parameters

override

true means that a lower camera detail will override this renderables detail level, false means it won't.

setPoseWeight()

void Ogre::Renderable::setPoseWeight ( size_t  index, float  w  )

inherited

setPosition()

void Ogre::v1::OverlayElement::setPosition ( Real  left, Real  top  )

inherited

Sets the position of the top-left corner of the element, relative to the screen size (1.0 = screen width / height)

setRenderQueueSubGroup()

void Ogre::Renderable::setRenderQueueSubGroup ( uint8  subGroup )

inlineinherited

Sets the render queue sub group.

Remarks

Within the same RenderQueue ID, you may want to have the renderables to have a specific order (i.e. have a mesh, but the hair submesh with alpha blending needs to be rendered last).

RenderQueue Subgroups are useful for manually sorting objects, just like RenderQueue IDs. However, RenderQueue IDs can also be useful for skipping large number of objects through clever compositing and thus a performance optimization. Subgroups cannot be used for such optimizations.

Parameters

subGroup

The sub group. This value can't exceed OGRE_MAKE_MASK( SubRqIdBits ) @See RenderQueue

setTiling()

void Ogre::v1::PanelOverlayElement::setTiling	(	Real	x,
		Real	y,
		ushort	layer = 0
	)

Sets the number of times textures should repeat.

Parameters

x	The number of times the texture should repeat horizontally
y	The number of times the texture should repeat vertically
layer	The texture layer to specify (only needs to be altered if you're using a multi-texture layer material)

setTop()

void Ogre::v1::OverlayElement::setTop ( Real  Top )

inherited

Sets the top of this element in relation to the screen (where 0 = top, 1.0 = bottom)

setTransparent()

void Ogre::v1::PanelOverlayElement::setTransparent

(

bool

isTransparent

)

Sets whether this panel is transparent (used only as a grouping level), or if it is actually rendered.

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

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.

setUserAny()

virtual OGRE_DEPRECATED void Ogre::Renderable::setUserAny ( const Any &  anything )

		Real	v1,
		Real	u2,
		Real	v2
	)

Sets the texture coordinates for the panel.

setVerticalAlignment()

virtual void Ogre::v1::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.

inherited

Sets the width of this element in relation to the screen (where 1.0 = screen width)
