Member Function Documentation

MatchTo()

override void Creatures.LegTarget.MatchTo ( Bone bone )

virtual

Function to match the target to the selected bone.

Parameters

bone	The bone to match to

This will put the target at the bone position and orientation and calculate the targetToBone rotation When the bone is null, the value isMatched will become false

Reimplemented from Creatures.Target.

Unmatch()

override void Creatures.LegTarget.Unmatch ( )

virtual

Set properties for the case no matching bone exists.

Reimplemented from Creatures.Target.

UpdateBones() [1/2]

void Creatures.LegTarget.UpdateBones

(

Leg

leg

)

Update the bones of the from this target.

Parameters

leg	The creature's leg to update

FemurRotation()

Quaternion Creatures.LegTarget.FemurRotation ( Vector3 targetPosition )

protected

Calculate the femur target orientation in world space.

Parameters

targetPosition

The inverse kinematics target position

Returns

The target orientation, may be identity when either the femur or tibia target is not defined

TibiaRotation()

Quaternion Creatures.LegTarget.TibiaRotation ( Vector3 targetPosition )

protected

Calculate the tibia target orientation in world space.

Parameters

targetPosition

Returns

The target orientation, may be identity when the tibia target is not defined

TarsusRotation()

Quaternion Creatures.LegTarget.TarsusRotation ( Quaternion targetRotation )

protected

Calculates the tarsus rotation in world space.

Parameters

targetRotation

The orientation of the inverse kinematics target

Returns

The tarsus orientation

UpdateFemur()

void Creatures.LegTarget.UpdateFemur ( Transform femurBone )

protected

Update the pose of the femur bone based on its target.

Parameters

femurBone

The femure bone Transform

UpdateTibia()

void Creatures.LegTarget.UpdateTibia ( Transform tibiaBone )

protected

Update the pose of the tibia bone based on its target.

Parameters

tibiaBone

The tibia bone Transform

UpdateTarsus()

void Creatures.LegTarget.UpdateTarsus ( Transform tarsusBone )

protected

Update the pose of the tarsus bone based on its target.

Parameters

tarsusBone

The tarsus bone Transform

CosineRule()

float Creatures.LegTarget.CosineRule ( float a, float b, float c )

static

Implementation of the Law of Cosines.

Parameters

a	Side a of the triangle
b	Side b of the triangle
c	Side c of the triangle

Returns

The angle between sides a and b

Align()

virtual void Creatures.Target.Align ( )

virtualinherited

Align the pose.

This will make the pose of the creature symmetric

Reimplemented in Creatures.HeadTarget, Creatures.Insects.HeadTarget, and Creatures.TailTarget.

UpdateBones() [2/2]

virtual void Creatures.Target.UpdateBones ( Bone bone )

virtualinherited

Update the pose of the bone from this target.

Parameters

bone	The bone for which the pose is updated

Reimplemented in Creatures.Insects.AntennaTarget, and Creatures.Insects.HeadTarget.
