Method Detail

act

public boolean act(float delta)

Description copied from class: Action

Updates the action based on time. Typically this is called each frame by Actor.act(float).

Specified by:

act in class Action

Parameters:

delta - Time in seconds since the last frame.

Returns:

true if the action is done. This method may continue to be called after the action is done.

finish

public void finish()

Skips to the end of the transition.

restart

public void restart()

Description copied from class: Action

Sets the state of the action so it can be run again.

Overrides:

restart in class Action

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 Action

getTime

public float getTime()

Gets the transition time so far.

setTime

public void setTime(float time)

Sets the transition time so far.

getDuration

public float getDuration()

setDuration

public void setDuration(float duration)

Sets the length of the transition in seconds.

getInterpolation

public Interpolation getInterpolation()

setInterpolation

public void setInterpolation(Interpolation interpolation)

isReverse

public boolean isReverse()

setReverse

public void setReverse(boolean reverse)

When true, the action's progress will go from 100% to 0%.
