### Opening a popup
|
|
|
|
In order to open a popup window, you must first define the position of the popup on your map.
|
|
|
|
You can position this popup by using a "rectangle" object in Tiled that you will place on an "object" layer.
|
|
|
|
<div class="row">
|
|
<div class="col">
|
|
<img src="https://workadventu.re/img/docs/screen_popup_tiled.png" class="figure-img img-fluid rounded" alt="" />
|
|
</div>
|
|
<div class="col">
|
|
<img src="https://workadventu.re/img/docs/screen_popup_in_game.png" class="figure-img img-fluid rounded" alt="" />
|
|
</div>
|
|
</div>
|
|
|
|
```
|
|
WA.ui.openPopup(targetObject: string, message: string, buttons: ButtonDescriptor[]): Popup
|
|
```
|
|
|
|
* **targetObject**: the name of the rectangle object defined in Tiled.
|
|
* **message**: the message to display in the popup.
|
|
* **buttons**: an array of action buttons defined underneath the popup.
|
|
|
|
Action buttons are `ButtonDescriptor` objects containing these properties.
|
|
|
|
* **label (_string_)**: The label of the button.
|
|
* **className (_string_)**: The visual type of the button. Can be one of "normal", "primary", "success", "warning", "error", "disabled".
|
|
* **callback (_(popup: Popup)=>void_)**: Callback called when the button is pressed.
|
|
|
|
Please note that `openPopup` returns an object of the `Popup` class. Also, the callback called when a button is clicked is passed a `Popup` object.
|
|
|
|
The `Popup` class that represents an open popup contains a single method: `close()`. This will obviously close the popup when called.
|
|
|
|
```javascript
|
|
class Popup {
|
|
/**
|
|
* Closes the popup
|
|
*/
|
|
close() {};
|
|
}
|
|
```
|
|
|
|
Example:
|
|
|
|
```javascript
|
|
let helloWorldPopup;
|
|
|
|
// Open the popup when we enter a given zone
|
|
helloWorldPopup = WA.room.onEnterZone('myZone', () => {
|
|
WA.ui.openPopup("popupRectangle", 'Hello world!', [{
|
|
label: "Close",
|
|
className: "primary",
|
|
callback: (popup) => {
|
|
// Close the popup when the "Close" button is pressed.
|
|
popup.close();
|
|
}
|
|
});
|
|
}]);
|
|
|
|
// Close the popup when we leave the zone.
|
|
WA.room.onLeaveZone('myZone', () => {
|
|
helloWorldPopup.close();
|
|
});
|
|
```
