Custom class¶

Define class

class MyNumberBar extends RexPlugins.UI.NumberBar {
  constructor(scene, config) {
    super(scene, config);
    // ...
    scene.add.existing(this);
  }
  // ...
}

Create instance

var numberBar = new MyNumberBar(scene, config);

Layout children¶

Arrange position of all elements.

numberBar.layout();

Get element¶

Get element

Background game object

var background = numberBar.getElement("background");

Icon game object

var icon = numberBar.getElement("icon");

Slider game object

Slider background

var sliderBackground = numberBar.getElement("slider.background");

Slider track

var sliderTrack = numberBar.getElement("slider.track");

Slider indicator

var sliderIndicator = numberBar.getElement("slider.indicator");

Slider thumb

var sliderThumb = numberBar.getElement("slider.thumb");

Text game object

var textObject = numberBar.getElement("text");

Get by name

var gameObject = numberBar.getElement("#" + name);
// var gameObject = numberBar.getElement('#' + name, recursive);

or

var gameObject = numberBar.getByName("#" + name);
// var gameObject = numberBar.getByName(name, recursive);

recursive : Set true to search all children recursively.

Enable¶

Get
```
var enable = numberBar.enable;
```

Set

numberBar.setEanble(enable);

or

numberBar.enable = enable;

Value¶

Change value will also change the position of slider thumb and width of slider indicator.

Get value

var value = numberBar.getValue(min, max); // value : min ~ max

or

var value = numberBar.getValue(); // value: 0 ~ 1

or

var value = numberBar.value; // value: 0 ~ 1

Set value

numberBar.setValue(value, min, max); // value: min ~ max

or

numberBar.setValue(value); // value: 0 ~ 1

or

numberBar.value = value; // value: 0 ~ 1

Increase value

numberBar.addValue(inc, min, max); // inc: min ~ max

or

numberBar.addValue(inc); // inc: 0 ~ 1

or

numberBar.value += inc; // inc: 0 ~ 1

Ease value¶

Ease value to

numberBar.easeValueTo(value, min, max);  // value: min ~ max

or

numberBar.easeValueTo(value);  // value: 0 ~ 1

Stop ease
```
numberBar.stopEaseValue();
```

Set ease duration

numberBar.setEaseValueDuration(duration);

Set ease function
```
numberBar.setEaseValueFunction(ease);
```
- ease : Ease function.

Text¶

Get text string
```
var s = numberBar.text;
```

Set text string

numberBar.setText(s);

or

numberBar.text = s;

Other properties¶

See sizer object, base sizer object, container-lite.

Events¶

numberBar.on('valuechange', function (newValue, oldValue, numberBar) {
    // numberBar.text = Math.round(Phaser.Math.Linear(0, 100, newValue));
}, scope);

On input start

numberBar.on('inputstart', function(pointer) {

}, scope);

On input end

numberBar.on('inputend', function(pointer) {

}, scope);
