Let's create a dungeon generator for Phaser 3 using Binary Space Partitioning - Create Instance

game-scene.ts

this.treeInstance = new Tree({
      map: {
        width: this.game.canvas.width,
        height: this.game.canvas.height,
        tileSize: 8
      },
      nodes: { size: { min: 10, max: 20 } }
});
