As part of the ongoing Tiled Map Editor tutorial this part looks at using Object Layers, which can be used to interface your tiled map with your games code.  This particular example includes the code using TypeScript and the Phaser game library.  If you need more information on Phaser I’ve done a tutorial series here.

 

The video of this tutorial is available here or embedded below.
