Set children interactive¶

Helper method, which applies click, tap, press, swipe behaiovrs on a game object, to detect input events of children.

sizer.setChildrenInteractive({
    // click: {mode: 'release', clickInterval: 100},

    // over: undefined,

    // press: {time: 251, threshold: 9},

    // tap: {time: 250, tapInterval: 200, threshold: 9, tapOffset: 10, 
    //       taps: undefined, minTaps: undefined, maxTaps: undefined,},

    // swipe: {threshold: 10, velocityThreshold: 1000, dir: '8dir'},

    // inputEventPrefix: 'child.',
    // eventEmitter: undefined
})

click : Configuration of Button behavior.
- false : Don't install Button behavior.
over :
- false : Don't fire over/out events
press : Configuration of Press behavior.
- false : Don't install Press behavior.
tap : Configuration of Tap behavior.
- false : Don't install Tap behavior.
swipe : Configuration of Swipe behavior.
- false : Don't install Swipe behavior.
inputEventPrefix : Prefix string of each event, default is 'child.'.
eventEmitter : Fire event through specific game object.

Note

Input behaviors are installed to this Sizer game object, not each child. And it assumes that all children are not overlapped. Use Button if user needs to enable/disable input behaviors of each child individually.

Events¶

Click

sizer.on('child.click', function(child, pointer) { 
    // ...
}, scope);

child : Triggered child game object.
pointer : Pointer object.

Pointer-over

sizer.on('child.over', function(child, pointer) { 
    // ...
}, scope);

Pointer-out

sizer.on('child.out', function(child, pointer) { 
    // ...
}, scope);

Press

sizer.on('child.pressstart', function(child, pointer) { 
    // ...
}, scope);

sizer.on('child.pressend', function(child, pointer) { 
    // ...
}, scope);

Tap

sizer.on(tapEventName, function(child, pointer) { 
    // ...
}, scope);

tapEventName : 'child.1tap', 'child.2tap', 'child.3tap', etc ...

Swipe
```
sizer.on(swipeEventName, function(child, pointer) { 
    // ...
}, scope);
```
- swipeEventName : 'child.swipeleft', 'child.swiperight', 'child.swipeup', 'child.swipedown'.

Behaviors¶

Flip: Flip game object to another face by scaling width/height.

var flip = scene.rexUI.add.flip(gameObject, config);

or

var flip = new RexPlugins.UI.Flip(gameObject, config);

Helper methods¶

Get parent¶

Get parent sizer

var parentSizer = scene.rexUI.getParentSizer(gameObject);

gameObject : Any game object added to sizer.

Get topmost sizer

var topmostSizer = scene.rexUI.getTopmostSizer(gameObject);

gameObject : Any game object added to sizer.

Show/hide¶

Show

scene.rexUI.show(gameObject);
scene.rexUI.getTopmostSizer(gameObject).layout();

Hide

scene.rexUI.hide(gameObject);
scene.rexUI.getTopmostSizer(gameObject).layout();

Is shown

var isShown = scene.rexUI.isShown(gameObject);

Is pointer in bounds¶

var isInBounds = scene.rexUI.isInTouching(gameObject);
// var isInBounds = scene.rexUI.isInTouching(gameObject, pointer);

Event promise ¶

Get event promise
```
var promise = scene.rexUI.waitEvent(eventEmitter, eventName)
    .then(function() {

    })
```
- eventEmitter : Any kind of event emitter. for example, game object, or tween task, or scene event
Get complete event promise
```
var promise = scene.rexUI.waitComplete(eventEmitter)
    .then(function() {

    })
```
- eventEmitter : Event emitter which will fire 'complete' event, for example, tween task.

View port¶

View port is a rectangle of current visible area.

var viewport = scene.rexUI.viewport;

Which will be changed after resizing

scene.scale.on('resize', function() {
    var viewport = scene.rexUI.viewport;
    /*
    sizer
        .setPosition(viewport.centerX, viewport.centerY)
        .setMinSize(viewport.width, viewport.height)
        .layout();
    */
});
