Detailed Description

Represents the state of an animation and the weight of its influence.

Remarks: Other classes can hold instances of this class to store the state of any animations they are using.

Member Typedef Documentation

◆ BoneBlendMask

typedef std::vector<float> Ogre::AnimationState::BoneBlendMask

Typedef for an array of float values used as a bone blend mask.

Constructor & Destructor Documentation

◆ AnimationState() [1/2]

Ogre::AnimationState::AnimationState	(	const String &	animName,
		AnimationStateSet *	parent,
		Real	timePos,
		Real	length,
		Real	weight = `1.0`,
		bool	enabled = `false`
	)

Normal constructor with all params supplied.

Parameters

animName	The name of this state.
parent	The parent AnimationStateSet that this state will belong to.
timePos	The position, in seconds, where this state will begin.
length	The length, in seconds, of this animation state.
weight	Weight to apply the animation state with.
enabled	Whether the animation state is enabled.

◆ AnimationState() [2/2]

Ogre::AnimationState::AnimationState	(	AnimationStateSet *	parent,
		const AnimationState &	rhs
	)

Constructor to copy from an existing state with new parent.

Member Function Documentation

◆ getAnimationName()

const String& Ogre::AnimationState::getAnimationName ( ) const

Gets the name of the animation to which this state applies.

◆ getTimePosition()

Real Ogre::AnimationState::getTimePosition ( void ) const

Gets the time position for this animation.

Referenced by Ogre::AnimationStateControllerValue::getValue().

◆ setTimePosition()

void Ogre::AnimationState::setTimePosition ( Real timePos )

Sets the time position for this animation.

Referenced by Ogre::AnimationStateControllerValue::setValue().

◆ getLength()

Real Ogre::AnimationState::getLength ( ) const

Gets the total length of this animation (may be shorter than whole animation)

Referenced by Ogre::AnimationStateControllerValue::getValue(), and Ogre::AnimationStateControllerValue::setValue().

◆ setLength()

void Ogre::AnimationState::setLength ( Real len )

Sets the total length of this animation (may be shorter than whole animation)

◆ getWeight()

Real Ogre::AnimationState::getWeight ( void ) const

Gets the weight (influence) of this animation.

◆ setWeight()

void Ogre::AnimationState::setWeight ( Real weight )

Sets the weight (influence) of this animation.

◆ addTime()

void Ogre::AnimationState::addTime ( Real offset )

Modifies the time position, adjusting for animation length.

Parameters

offset The amount of time, in seconds, to extend the animation.

Remarks: This method loops at the edges if animation looping is enabled.

Referenced by Ogre::AnimationStateControllerValue::setValue().

◆ hasEnded()

bool Ogre::AnimationState::hasEnded ( void ) const

Returns true if the animation has reached the end and is not looping.

◆ getEnabled()

bool Ogre::AnimationState::getEnabled ( void ) const

Returns true if this animation is currently enabled.

◆ setEnabled()

void Ogre::AnimationState::setEnabled ( bool enabled )

Sets whether this animation is enabled.

◆ operator==()

bool Ogre::AnimationState::operator== ( const AnimationState & rhs ) const

Equality operator.

◆ operator!=()

bool Ogre::AnimationState::operator!= ( const AnimationState & rhs ) const

Inequality operator.

◆ setLoop()

void Ogre::AnimationState::setLoop ( bool loop )

inline

Sets whether or not an animation loops at the start and end of the animation if the time continues to be altered.

◆ getLoop()

bool Ogre::AnimationState::getLoop ( void ) const

inline

Gets whether or not this animation loops

◆ copyStateFrom()

void Ogre::AnimationState::copyStateFrom ( const AnimationState & animState )

Copies the states from another animation state, preserving the animation name (unlike operator=) but copying everything else.

Parameters

animState Reference to animation state which will use as source.

◆ getParent()

AnimationStateSet* Ogre::AnimationState::getParent ( void ) const

inline

Get the parent animation state set.

◆ createBlendMask()

void Ogre::AnimationState::createBlendMask	(	size_t	blendMaskSizeHint,
		float	initialWeight = `1.0f`
	)

Create a new blend mask with the given number of entries.

In addition to assigning a single weight value to a skeletal animation, it may be desirable to assign animation weights per bone using a 'blend mask'.

Parameters

blendMaskSizeHint	The number of bones of the skeleton owning this AnimationState.
initialWeight	The value all the blend mask entries will be initialised with (negative to skip initialisation)

◆ destroyBlendMask()

void Ogre::AnimationState::destroyBlendMask ( )

Destroy the currently set blend mask.

◆ _setBlendMaskData()

void Ogre::AnimationState::_setBlendMaskData ( const float * blendMaskData )

Set the blend mask data (might be dangerous)

The size of the array should match the number of entries the: blend mask was created with.

Stick to the setBlendMaskEntry method if you don't know exactly what you're doing.

◆ _setBlendMask()

void Ogre::AnimationState::_setBlendMask ( const BoneBlendMask * blendMask )

Set the blend mask.

The size of the array should match the number of entries the: blend mask was created with.

Stick to the setBlendMaskEntry method if you don't know exactly what you're doing.

◆ getBlendMask()

const BoneBlendMask* Ogre::AnimationState::getBlendMask ( ) const

inline

Get the current blend mask (const version, may be 0)

◆ hasBlendMask()

bool Ogre::AnimationState::hasBlendMask ( ) const

inline

Return whether there is currently a valid blend mask set.

◆ setBlendMaskEntry()

void Ogre::AnimationState::setBlendMaskEntry	(	size_t	boneHandle,
		float	weight
	)

Set the weight for the bone identified by the given handle.

◆ getBlendMaskEntry()

float Ogre::AnimationState::getBlendMaskEntry ( size_t boneHandle ) const

inline

Get the weight for the bone identified by the given handle.
