public Class RotateToAction

extends TemporalAction
Class Inheritance
Imports
com.badlogic.gdx.math.MathUtils
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.
