Clearing Tilemap

I am doing some procedural tilemap stuff but I can't seem to clear out the existing tile.

Code (JavaScript):

1.  
2.         static ClearTileMap(tilemap:ut.Tilemap2D.Tilemap)
3.         {
4.             tilemap.tiles.forEach(function(tile:ut.Tilemap2D.TileData, index:Number,array: ut.Tilemap2D.TileData[]){
5.               if(!tile.tile.isNone())
6.                this.world.destroyEntity(tile.tile);
7.             } );
8.        
9.         }

I get the error

tsc-emit.js:55 Uncaught TypeError: Cannot read property 'destroyEntity' of undefined

Am I missing something?

 

I noticed the this.world isn't really accessible within the loop so I tried this trick

Code (CSharp):

1.  
2. namespace game {
3.  
4.     export class MapBehaviorFilter extends ut.EntityFilter {
5.         tilemap: ut.Tilemap2D.Tilemap;
6.  
7.     }
8.  
9.     export class MapBehavior extends ut.ComponentBehaviour {
10.  
11.         data: MapBehaviorFilter;
12.  
13.         // ComponentBehaviour lifecycle events
14.         // uncomment any method you need
15.        
16.         // this method is called for each entity matching the MapBehaviorFilter signature, once when enabled
17.         OnEntityEnable():void
18.         {
19.             let world = this.world;
20.             this.data.tilemap.tiles.forEach(function(value:ut.Tilemap2D.TileData, index:Number,array: ut.Tilemap2D.TileData[]){
21.                
22.                 world.destroyEntity(value.tile);
23.            
24.             } );
25.  
26.         }
27.  
28.         // this method is called for each entity matching the MapBehaviorFilter signature, every frame it's enabled
29.         //OnEntityUpdate():void { }
30.  
31.         // this method is called for each entity matching the MapBehaviorFilter signature, once when disabled
32.         //OnEntityDisable():void { }
33.  
34.     }
35. }

And I got 2 new Error

I seriously hate Javascript

solution to clear is

Code (JavaScript):

1.  
2. this.data.tilemap.tiles = [];
