|
|
* 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} scaleX - The amount to set the `scaleX` property to.
|
|
* @param {number} [scaleY] - The amount to set the `scaleY` property to. If `undefined` or `null` it uses the `scaleX` value.
|
|
* @param {number} [stepX=0] - This is added to the `scaleX` amount, multiplied by the iteration counter.
|
|
* @param {number} [stepY=0] - This is added to the `scaleY` 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|Phaser.GameObjects.GameObject[])} The array of objects that were passed to this Action.
