 * @param {(array|Phaser.GameObjects.GameObject[])} items - The array of items to be updated by this action.
 * @param {number} value - The amount to set the property to.
 * @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.
