How do I set up equipment in tabletopkit and have it interact with the app model?

To set up equipment in TabletopKit and have it interact with the app model, you can follow these steps:

Initial Setup: Begin by setting up the initial state of the game. This involves defining everything that players can see and interact with during play. You start with a table, decide where everyone will sit, and place a board with game tiles on top. Then, add tangible objects like player pawns, cards, and dice to bring the game to life. The table can be circular or rectangular, and all setup and gameplay happen on this tabletop.
Define Equipment: Each piece of equipment, such as the board, tiles, pawns, cards, and dice, is represented as a different type of equipment. For example, a pawn is a physical object rendered as a RealityKit entity. It has an inherent size and can be interacted with by players. Each pawn is associated with a specific seat, meaning only the player in that seat can move it. The pawn conforms to the entity equipment protocol, which means it has an attached RealityKit entity.
Interaction and Gestures: TabletopKit monitors for system gestures, which are processed and handed back to you as interactions. You can append actions to these interactions to modify the game state. For instance, when a player pinches and drags a card, you can turn this gesture into a TabletopKit interaction and append an action to move the card to a new pile.
Multiplayer and Networking: For multiplayer games, TabletopKit handles networking for you. It ensures that the game state is synchronized between all players by syncing actions. You can start a group activity session with just a few lines of code, and the framework will manage the rest.

For more detailed guidance, you can refer to the session Meet TabletopKit for visionOS at the chapter "Set up the play surface" for setting up the game and Configure multiplayer for multiplayer configuration.
