Using atlas with typescript

[flatliner]

app.loader.add('images/pentamino.json')
    .load(() => {
        setup();
    });

let tileset = app.loader.resources['images/pentamino.json'];

let part:PIXI.Sprite = new PIXI.Sprite(tileset.textures['pink.png']);

It generates an error: "Object is possibly 'undefined'" related to PIXI.Sprite() argument tileset.textures['pink.png'].

Is it possible to fix this in anyway or better reject typescript to recycled bin?

Use

 

let part:PIXI.Sprite = new PIXI.Sprite(tileset.textures['pink.png']!);

Yes, but this:

let part:PIXI.Sprite = new PIXI.Sprite(tileset.textures!['pink.png']);

... and how could I have missed this feature when studying typescript ...

Thank you!
