AlphaAction

public AlphaAction()

Method Details

begin

protected void begin()

Description copied from class: TemporalAction

Called the first time TemporalAction.act(float) is called. This is a good place to query the actor's starting state.

Overrides:

begin in class TemporalAction

update

protected void update(float percent)

Description copied from class: TemporalAction

Called each frame.

Specified by:

update in class TemporalAction

Parameters:

percent - The percentage of completion for this action, growing from 0 to 1 over the duration. If reversed, this will shrink from 1 to 0.

reset

public void reset()

Description copied from class: Action

Resets the optional state of this action to as if it were newly created, allowing the action to be pooled and reused. State required to be set for every usage of this action or computed during the action does not need to be reset.

The default implementation calls Action.restart().

If a subclass has optional state, it must override this method, call super, and reset the optional state.

Specified by:

reset in interface Pool.Poolable

Overrides:

reset in class TemporalAction

getColor

public Color getColor()

setColor

public void setColor(Color color)

Sets the color to modify. If null (the default), the actor's color will be used.

getAlpha

public float getAlpha()

setAlpha

public void setAlpha(float alpha)
