## Detailed Description

Represents the state of an animation and the weight of it's influence.

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

## Constructor & Destructor Documentation

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.

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

constructor to copy from an existing state with new parent

virtual Ogre::AnimationState::~AnimationState | ( |  | ) | `[virtual]`

Destructor - is here because class has virtual functions and some compilers would whine if it won't exist.

## Member Function Documentation

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

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

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

Gets the time position for this animation.

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

Sets the time position for this animation.

Real Ogre::AnimationState::getLength | ( |  | ) | const

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

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

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

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

Gets the weight (influence) of this animation.

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

Sets the weight (influence) of this animation.

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

Modifies the time position, adjusting for animation length.

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

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

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

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

Returns true if this animation is currently enabled.

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

Sets whether this animation is enabled.

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

Equality operator.

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

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

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

Definition at line 99 of file OgreAnimationState.h.

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

Gets whether or not this animation loops.

Definition at line 101 of file OgreAnimationState.h.

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.

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

Get the parent animation state set.

Definition at line 110 of file OgreAnimationState.h.

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)

void Ogre::AnimationState::destroyBlendMask | ( |  | ) |

destroy the currently set blend mask

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.

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.

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

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

Definition at line 142 of file OgreAnimationState.h.

bool Ogre::AnimationState::hasBlendMask | ( |  | ) | const

return whether there is currently a valid blend mask set

Definition at line 144 of file OgreAnimationState.h.

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

set the weight for the bone identified by the given handle

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

get the weight for the bone identified by the given handle
