# API Room functions Reference
|
|
|
|
### Working with group layers
|
|
If you use group layers in your map, to reference a layer in a group you will need to use a `/` to join layer names together.
|
|
|
|
Example :
|
|
<div class="row">
|
|
<div class="col">
|
|
<img src="https://workadventu.re/img/docs/groupLayer.png" class="figure-img img-fluid rounded" alt="" />
|
|
</div>
|
|
</div>
|
|
|
|
The name of the layers of this map are :
|
|
* `entries/start`
|
|
* `bottom/ground/under`
|
|
* `bottom/build/carpet`
|
|
* `wall`
|
|
|
|
### Detecting when the user enters/leaves a zone
|
|
|
|
```
|
|
WA.room.onEnterZone(name: string, callback: () => void): void
|
|
WA.room.onLeaveZone(name: string, callback: () => void): void
|
|
```
|
|
|
|
Listens to the position of the current user. The event is triggered when the user enters or leaves a given zone. The name of the zone is stored in the map, on a dedicated layer with the `zone` property.
|
|
|
|
<div>
|
|
<figure class="figure">
|
|
<img src="https://workadventu.re/img/docs/trigger_event.png" class="figure-img img-fluid rounded" alt="" />
|
|
<figcaption class="figure-caption">The `zone` property, applied on a layer</figcaption>
|
|
</figure>
|
|
</div>
|
|
|
|
* **name**: the name of the zone, as defined in the `zone` property.
|
|
* **callback**: the function that will be called when a user enters or leaves the zone.
|
|
|
|
Example:
|
|
|
|
```javascript
|
|
WA.room.onEnterZone('myZone', () => {
|
|
WA.chat.sendChatMessage("Hello!", 'Mr Robot');
|
|
})
|
|
|
|
WA.room.onLeaveZone('myZone', () => {
|
|
WA.chat.sendChatMessage("Goodbye!", 'Mr Robot');
|
|
})
|
|
```
|
|
|
|
### Show / Hide a layer
|
|
```
|
|
WA.room.showLayer(layerName : string): void
|
|
WA.room.hideLayer(layerName : string) : void
|
|
```
|
|
These 2 methods can be used to show and hide a layer.
|
|
if `layerName` is the name of a group layer, show/hide all the layer in that group layer.
|
|
|
|
Example :
|
|
```javascript
|
|
WA.room.showLayer('bottom');
|
|
//...
|
|
WA.room.hideLayer('bottom');
|
|
```
|
|
|
|
### Set/Create properties in a layer
|
|
|
|
```
|
|
WA.room.setProperty(layerName : string, propertyName : string, propertyValue : string | number | boolean | undefined) : void;
|
|
```
|
|
|
|
Set the value of the `propertyName` property of the layer `layerName` at `propertyValue`. If the property doesn't exist, create the property `propertyName` and set the value of the property at `propertyValue`.
|
|
|
|
Note :
|
|
To unset a property from a layer, use `setProperty` with `propertyValue` set to `undefined`.
|
|
|
|
Example :
|
|
```javascript
|
|
WA.room.setProperty('wikiLayer', 'openWebsite', 'https://www.wikipedia.org/');
|
|
```
|
|
|
|
### Get the room id
|
|
|
|
```
|
|
WA.room.id: string;
|
|
```
|
|
|
|
The ID of the current room is available from the `WA.room.id` property.
|
|
|
|
{.alert.alert-info}
|
|
You need to wait for the end of the initialization before accessing `WA.room.id`
|
|
|
|
```typescript
|
|
WA.onInit().then(() => {
|
|
console.log('Room id: ', WA.room.id);
|
|
// Will output something like: 'https://play.workadventu.re/@/myorg/myworld/myroom', or 'https://play.workadventu.re/_/global/mymap.org/map.json"
|
|
})
|
|
```
|
|
|
|
### Get the map URL
|
|
|
|
```
|
|
WA.room.mapURL: string;
|
|
```
|
|
|
|
The URL of the map is available from the `WA.room.mapURL` property.
|
|
|
|
{.alert.alert-info}
|
|
You need to wait for the end of the initialization before accessing `WA.room.mapURL`
|
|
|
|
```typescript
|
|
WA.onInit().then(() => {
|
|
console.log('Map URL: ', WA.room.mapURL);
|
|
// Will output something like: 'https://mymap.org/map.json"
|
|
})
|
|
```
|
|
|
|
|
|
|
|
### Getting map data
|
|
```
|
|
WA.room.getTiledMap(): Promise<ITiledMap>
|
|
```
|
|
|
|
Returns a promise that resolves to the JSON map file.
|
|
|
|
```javascript
|
|
const map = await WA.room.getTiledMap();
|
|
console.log("Map generated with Tiled version ", map.tiledversion);
|
|
```
|
|
|
|
Check the [Tiled documentation to learn more about the format of the JSON map](https://doc.mapeditor.org/en/stable/reference/json-map-format/).
|
|
|
|
### Changing tiles
|
|
```
|
|
WA.room.setTiles(tiles: TileDescriptor[]): void
|
|
```
|
|
Replace the tile at the `x` and `y` coordinates in the layer named `layer` by the tile with the id `tile`.
|
|
|
|
If `tile` is a string, it's not the id of the tile but the value of the property `name`.
|
|
<div class="row">
|
|
<div class="col">
|
|
<img src="https://workadventu.re/img/docs/nameIndexProperty.png" class="figure-img img-fluid rounded" alt="" />
|
|
</div>
|
|
</div>
|
|
|
|
`TileDescriptor` has the following attributes :
|
|
* **x (number) :** The coordinate x of the tile that you want to replace.
|
|
* **y (number) :** The coordinate y of the tile that you want to replace.
|
|
* **tile (number | string) :** The id of the tile that will be placed in the map.
|
|
* **layer (string) :** The name of the layer where the tile will be placed.
|
|
|
|
**Important !** : If you use `tile` as a number, be sure to add the `firstgid` of the tileset of the tile that you want to the id of the tile in Tiled Editor.
|
|
|
|
Note: If you want to unset a tile, use `setTiles` with `tile` set to `null`.
|
|
|
|
Example :
|
|
```javascript
|
|
WA.room.setTiles([
|
|
{x: 6, y: 4, tile: 'blue', layer: 'setTiles'},
|
|
{x: 7, y: 4, tile: 109, layer: 'setTiles'},
|
|
{x: 8, y: 4, tile: 109, layer: 'setTiles'},
|
|
{x: 9, y: 4, tile: 'blue', layer: 'setTiles'}
|
|
]);
|
|
```
