Method Details

doInterpolate

public void doInterpolate(double t)

Specified by:

doInterpolate in class BlendableAction

getActions

protected Action[] getActions()

getBlendSpace

public BlendSpace getBlendSpace()

getSpeed

public double getSpeed()

Description copied from class: Action

Retrieves the speedup factor applied by the layer for this action.

Overrides:

getSpeed in class Action

Returns:

the speed of frames.

See Also:

• for detailed documentation

getSpeedFactors

public double[] getSpeedFactors()

Returns:

The speed factor or null if there is none

setSpeedFactors

public void setSpeedFactors(double... speedFactors)

Used to resolve the slow motion side effect caused by stretching actions that doesn't have the same length.

Parameters:

speedFactors - The speed factors for each child action. BlendAction will interpolate factor for current frame based on blend weight and will multiply it to speed.

clearSpeedFactors

public void clearSpeedFactors()

applyDefaultSpeedFactors

public void applyDefaultSpeedFactors()

BlendAction will stretch it's child actions if they don't have the same length. This might cause stretched animations to run slowly. This method generates factors based on how much actions are stretched. Multiplying this factor to base speed will resolve the slow-motion side effect caused by stretching. BlendAction will use the blend weight taken from BlendSpace to interpolate the speed factor for current frame.

setFirstActiveIndex

protected void setFirstActiveIndex(int index)

setSecondActiveIndex

protected void setSecondActiveIndex(int index)

getTargets

public Collection<HasLocalTransform> getTargets()

Specified by:

getTargets in class BlendableAction

collectTransform

public void collectTransform(HasLocalTransform target,
 Transform t,
 float weight,
 BlendableAction source)

Specified by:

collectTransform in class BlendableAction
