Animator
Namespace: UnityEngine
Parent class: Behaviour
Description
Interface to control the Mecanim animation system.
Variables
animatePhysics When turned on, animations will be executed in the physics loop. This is only useful in conjunction with kinematic rigidbodies.
applyRootMotion Should root motion be applied?
avatar Gets/Sets the current Avatar.
bodyPosition The position of the body center of mass.
bodyRotation The rotation of the body center of mass.
cullingMode Controls culling of this Animator component.
deltaPosition Gets the avatar delta position for the last evaluated frame.
deltaRotation Gets the avatar delta rotation for the last evaluated frame.
feetPivotActive Blends pivot point between body center of mass and feet pivot. At 0%, the blending point is body center of mass. At 100%, the blending point is feet pivot.
gravityWeight The current gravity weight based on current animations that are played.
humanScale Returns the scale of the current Avatar for a humanoid rig, (1 by default if the rig is generic).
isHuman Returns true if the current rig is humanoid, false if it is generic.
isMatchingTarget If automatic matching is active.
layerCount The AnimatorController layer count.
leftFeetBottomHeight Get left foot bottom height.
pivotPosition Get the current position of the pivot.
pivotWeight Gets the pivot weight.
playbackTime Sets the playback position in the recording buffer.
recorderStartTime Start time of the first frame of the buffer relative to the frame at which StartRecording was called.
recorderStopTime End time of the recorded clip relative to when StartRecording was called.
rightFeetBottomHeight Get right foot bottom height.
rootPosition The root position, the position of the game object.
rootRotation The root rotation, the rotation of the game object.
runtimeAnimatorController The runtime representation of AnimatorController that controls the Animator.
speed The playback speed of the Animator. 1 is normal playback speed.
stabilizeFeet Automatic stabilization of feet during transition and blending.
targetPosition Returns the position of the target specified by SetTarget(AvatarTarget targetIndex, float targetNormalizedTime)).
targetRotation Returns the rotation of the target specified by SetTarget(AvatarTarget targetIndex, float targetNormalizedTime)).

GetNextAnimatorStateInfo Gets the next State information on a specified AnimatorController layer.
InterruptMatchTarget Interrupts the automatic target matching.
IsInTransition Is the specified AnimatorController layer in a transition.
IsParameterControlledByCurve Returns true if a parameter is controlled by an additional curve on an animation.
MatchTarget Automatically adjust the gameobject position and rotation so that the AvatarTarget reaches the matchPosition when the current state is at the specified progress.
Play Plays a state.
SetBool Sets the value of a bool parameter.
SetFloat Sets the value of a float parameter.
SetIKPosition Sets the position of an IK goal.
SetIKPositionWeight Sets the translative weight of an IK goal (0 = at the original animation before IK, 1 = at the goal).
SetIKRotation Sets the rotation of an IK goal.
SetIKRotationWeight Sets the rotational weight of an IK goal (0 = rotation before IK, 1 = rotation at the IK goal).
SetInteger Sets the value of an integer parameter.
SetLayerWeight Sets the layer's current weight.
SetLookAtPosition Sets the look at position.
SetLookAtWeight Set look at weights.
SetTarget Sets an AvatarTarget and a targetNormalizedTime for the current state.
SetTrigger Sets a trigger parameter to active or inactive.
StartPlayback Sets the animator in playback mode.
StartRecording Sets the animator in recording mode, and allocates a circular buffer of size frameCount.
StopPlayback Stops the animator playback mode. When playback stops, the avatar resumes getting control from game logic.
StopRecording Stops animator record mode.

Root Transform
Types
Root Transform Position (XZ)
Root Transform Position (Y)
manually adjust the AnimationClip height using the Offset setting
Note: the Animator.gravityWeight is driven by Bake Into Pose position Y. When enabled, gravityWeight = 1, when disable = 0. gravityWeight is blended for clips when transitioning between states.
Most of the AnimationClips will enable this setting. Only clips that will change the GameObject height should have this turned off, like jump up or down.
Y component of the motion will stay on the Body Transform (Pose)
This means that this clip won't change the Game Object Height
The Y component of the Root Transform will be constant and Delta Root Position Y will be 0
Feet
Thus the blending point always remains around the feet which prevents floating problem when blending or transitioning.
When using Feet the Root Transform Position Y will match the lowest foot Y for all frames
Center of Mass
Root Transform Rotation
Option
Offset
Baked Into Pose
Only AnimationClips that have similar start and stop Root Orientation should use this option (walks/run)
This means the the Game Object will not be rotated at all by that AnimationClip.
The Root Orientation will be constant and delta Orientation will be identity
The orientation will stay on the body transform (or Pose)
Based Upon
the orientation of the clip
Original
automatically add the authored offset found in the imported clip
It is usually used with Keyframed data to respect orientation that was set by the artist.
clip will be oriented to follow the forward vector of body
This default setting works well for most Motion Capture (Mocap) data like walks, runs, and jumps, but it will fail with motion like strafing where the motion is perpendicular to the body's forward vector. In those cases you can manually adjust the orientation using the Offset setting
a projection on the Y plane of the Body Transform and is computed at runtime
This change in transform is then applied to the Game Object to make it move
At every frame, a change in the Root Transform is computed
Body Transform
Body Transform and Orientation are stored in the Animation Clip (using the Muscle definitions set up in the Avatar)
Body Orientation
average of the lower and upper body orientation relative to the Avatar T-Pose
mass center of the character
They are the only world-space curves stored in the Animation Clip. Everything else: muscle curves and IK goals (Hands and Feet) are stored relative to the body transform
