|
* The optional `stepX` and `stepY` properties are applied incrementally, multiplied by each item in the array.

* @param {(array|Phaser.GameObjects.GameObject[])} items - The array of items to be updated by this action.
|
|
* @param {number} x - The amount to set the `x` property to.
|
|
* @param {number} [y=x] - The amount to set the `y` property to. If `undefined` or `null` it uses the `x` value.
|
|
* @param {number} [stepX=0] - This is added to the `x` amount, multiplied by the iteration counter.
|
|
* @param {number} [stepY=0] - This is added to the `y` amount, multiplied by the iteration counter.
|
|
* @param {number} [index=0] - An optional offset to start searching from within the items array.
|
|
* @param {number} [direction=1] - The direction to iterate through the array. 1 is from beginning to end, -1 from end to beginning.
|
|
*
|
|
* @return {(array|Phaser.GameObjects.GameObject[])} The array of objects that were passed to this Action.
