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 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
animNameThe name of this state.
parentThe parent AnimationStateSet that this state will belong to.
timePosThe position, in seconds, where this state will begin.
lengthThe length, in seconds, of this animation state.
weightWeight to apply the animation state with.
enabledWhether 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
offsetThe amount of time, in seconds, to extend the animation.
Remarks
This method loops at the edges if animation looping is enabled.

◆ 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
animStateReference 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
blendMaskSizeHintThe number of bones of the skeleton owning this AnimationState.
initialWeightThe 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.
