Class RotateToAction

java.lang.Object

com.badlogic.gdx.scenes.scene2d.Action

com.badlogic.gdx.scenes.scene2d.actions.TemporalAction

com.badlogic.gdx.scenes.scene2d.actions.RotateToAction

All Implemented Interfaces:

Pool.Poolable

public class RotateToAction
extends TemporalAction

Sets the actor's rotation from its current value to a specific value. By default, the rotation will take you from the starting value to the specified value via simple subtraction. For example, setting the start at 350 and the target at 10 will result in 340 degrees of movement. If the action is instead set to useShortestDirection instead, it will rotate straight to the target angle, regardless of where the angle starts and stops. For example, starting at 350 and rotating to 10 will cause 20 degrees of rotation.

RotateToAction

public RotateToAction()

RotateToAction

public RotateToAction(boolean useShortestDirection)

Parameters:

useShortestDirection - Set to true to move directly to the closest angle

Method Detail

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.
