boolean |
act(float delta)
Updates the action based on time. |
protected void |
begin()
Called the first time act(float) is called. |
protected void |
end()
Called the last time act(float) is called. |
void |
finish()
Skips to the end of the transition. |

getInterpolation()
|
float |
getTime()
Gets the transition time so far. |
boolean |
isReverse()
|
void |
reset()
Resets the optional state of this action to as if it were newly created, allowing the action to be pooled and reused. |
void |
restart()
Sets the state of the action so it can be run again. |
void |
setDuration(float duration)
Sets the length of the transition in seconds. |
void |
setInterpolation(Interpolation interpolation)
|
void |
setReverse(boolean reverse)
When true, the action's progress will go from 100% to 0%. |
void |
setTime(float time)
Sets the transition time so far. |
protected abstract void |
update(float percent)
Called each frame. |

public boolean act(float delta)
Action
Actor.act(float)
.
act
in class Action
delta
- Time in seconds since the last frame.
protected void begin()
act(float)
is called. This is a good place to query the actor's
starting
state.
protected void end()
act(float)
is called.
protected abstract void update(float percent)
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.public void finish()
public void restart()
Action
restart
in class Action
public void reset()
Action
The default implementation calls Action.restart()
.
If a subclass has optional state, it must override this method, call super, and reset the optional state.
