Phaser Class: ScaleMinMax

## Phaser.Component. ScaleMinMax

#### new ScaleMinMax()

  The ScaleMinMax component allows a Game Object to limit how far it can be scaled by its parent.

  Source - gameobjects/components/ScaleMinMax.js, line 12

### Members

#### scaleMax :Phaser.Point

  The maximum scale this Game Object will scale up to.

  It allows you to prevent a parent from scaling this Game Object higher than the given value.

  Set it to `null` to remove the limit.

  Source - gameobjects/components/ScaleMinMax.js, line 46

#### scaleMin :Phaser.Point

  The minimum scale this Game Object will scale down to.

  It allows you to prevent a parent from scaling this Game Object lower than the given value.

  Set it to `null` to remove the limit.

  Source - gameobjects/components/ScaleMinMax.js, line 36

#### transformCallback :function

  The callback that will apply any scale limiting to the worldTransform.

  Source - gameobjects/components/ScaleMinMax.js, line 20

#### transformCallbackContext :object

  The context under which `transformCallback` is called.

### Methods

#### setScaleMinMax(minX, minY, maxX, maxY)

  Sets the scaleMin and scaleMax values. These values are used to limit how far this Game Object will scale based on its parent.

  For example if this Game Object has a `minScale` value of 1 and its parent has a `scale` value of 0.5, the 0.5 will be ignored
  and the scale value of 1 will be used, as the parents scale is lower than the minimum scale this Game Object should adhere to.

  By setting these values you can carefully control how Game Objects deal with responsive scaling.

  If only one parameter is given then that value will be used for both scaleMin and scaleMax:
  `setScaleMinMax(1)` = scaleMin.x, scaleMin.y, scaleMax.x and scaleMax.y all = 1

  If only two parameters are given the first is set as scaleMin.x and y and the second as scaleMax.x and y:
  `setScaleMinMax(0.5, 2)` = scaleMin.x and y = 0.5 and scaleMax.x and y = 2

  If you wish to set `scaleMin` with different values for x and y then either modify Game Object.scaleMin directly,
  or pass `null` for the `maxX` and `maxY` parameters.

  Call `setScaleMinMax(null)` to clear all previously set values.

  ##### Parameters:

  Name | Type | Description
  --- | --- | ---
  `minX` | number | null | The minimum horizontal scale value this Game Object can scale down to.
  `minY` | number | null | The minimum vertical scale value this Game Object can scale down to.
  `maxX` | number | null | The maximum horizontal scale value this Game Object can scale up to.
  `maxY` | number | null | The maximum vertical scale value this Game Object can scale up to.
