/** /**
* [description] * Takes an array of Game Objects, or any objects that have a public `rotation` property,
* and then adds the given value to each of their `rotation` properties.
*
* The optional `step` property is applied incrementally, multiplied by each item in the array.
*
* To use this with a Group: `Rotate(group.getChildren(), value, step)`
* *
* @function Phaser.Actions.Rotate * @function Phaser.Actions.Rotate
* @since 3.0.0 * @since 3.0.0
* *
* @param {array} items - An array of Game Objects. The contents of this array are updated by this Action. * @param {array|Phaser.GameObjects.GameObject[]} items - The array of items to be updated by this action.
* @param {number} value - [description] * @param {number} value - The amount to be added to the `rotation` property (in radians).
* @param {number} [step=0] - [description] * @param {number} [step=0] - This is added to the `value` amount, multiplied by the iteration counter.
* @param {integer} [index=0] - An optional offset to start searching from within the items array.
* @param {integer} [direction=1] - The direction to iterate through the array. 1 is from beginning to end, -1 from end to beginning.
* *
* @return {array} The array of Game Objects that was passed to this Action. * @return {array} The array of objects that were passed to this Action.
