Texas Hold'em is built from many ECS components working together: a deck, a seating plan, a betting system for chips and turn order, a hand evaluator, three AI opponents, a paced HUD, and a director that connects them over an EventBus without any component referencing another. This code-along rebuilds the real BabylonJS Market poker table the same way it ships. You start from an empty scene, download the card assets, draw a felt table on screen, deal the player's hole cards, then add betting, hand ranking, the Randy, Bill, and Cali opponents, the turn pacer, the HUD, the table renderer, keyboard input, and finally the PokerTableDirector that schedules each phase of the hand. Every code fence is a verbatim slice of the live component source, and the scene you assemble ends byte-for-byte equal to the library's own example.scene.json.
