BonePose class

The applied local pose and world transform for a bone. This is the bone's unconstrained pose with constraints applied and the world transform computed by Skeleton::updateWorldTransform(Physics) and updateWorldTransform(Skeleton).

If the world transform is changed, call updateLocalTransform(Skeleton) before using the local transform. The local transform may be needed by other code (eg to apply another constraint).

After changing the world transform, call updateWorldTransform(Skeleton) on every descendant bone. It may be more convenient to modify the local transform instead, then call Skeleton::updateWorldTransform(Physics) to update the world transforms for all bones and apply constraints.

modifyWorld(int update) → void
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
parentToWorld(double parentX, double parentY) → Vector

Available on BonePose, provided by the BonePoseExtensions extension

rotateWorld(double degrees) → void
Rotates the world transform the specified amount.
set(BoneLocal pose) → void
inherited
setPosition(double x, double y) → void
Sets local x and y translation.
inherited
setScale(double scaleX, double scaleY) → void
Sets local scaleX and scaleY.
inherited
toString() → String
A string representation of this object.
inherited
update(Skeleton skeleton, Physics physics) → void
Called by Skeleton::updateCache() to compute the world transform, if needed.
override
updateLocalTransform(Skeleton skeleton) → void
Computes the local transform values from the world transform.
updateWorldTransform(Skeleton skeleton) → void
Computes the world transform using the parent bone's world transform and this applied local pose. Child bones are not updated.
validateLocalTransform(Skeleton skeleton) → void
If the world transform has been modified by constraints and the local transform no longer matches, updateLocalTransform() is called. Call this after Skeleton::updateWorldTransform(Physics) before using the applied local transform.
worldToLocal(double worldX, double worldY) → Vector

Available on BonePose, provided by the BonePoseExtensions extension

worldToLocalRotation(double worldRotation) → double
Transforms a world rotation to a local rotation.
worldToParent(double worldX, double worldY) → Vector

Available on BonePose, provided by the BonePoseExtensions extension
