How can I build a custom spatial template with 5 seats, spaced 1 meter apart from each other in an arc, with each seat facing the leftmost seat?

To build a custom spatial template with 5 seats, spaced 1 meter apart from each other in an arc, with each seat facing the leftmost seat, you can follow these steps:

1. Define the Template Structure:

   • Create a struct that conforms to the spatial template protocol.
   • Define an array of template elements where each element represents a seat.

2. Position the Seats:

   • Seats are positioned relative to the shared app's position using x and z offsets.
   • For an arc, you can calculate the positions using trigonometric functions to ensure they are spaced 1 meter apart.

3. Set Seat Directions:

   • Use the looking at method to orient each seat towards the leftmost seat.

Here is a simplified example based on the provided context:

struct CustomArcTemplate: SpatialTemplate {
    var elements: [SpatialTemplateElement] {
        let radius: Float = 1.0 // 1 meter apart
        let centerX: Float = 0.0
        let centerZ: Float = 4.0 // 4 meters in front of the app

        // Calculate positions in an arc
        let positions = [
            (x: centerX - 2 * radius, z: centerZ),
            (x: centerX - radius, z: centerZ + sqrt(3) * radius),
            (x: centerX, z: centerZ + 2 * sqrt(3) * radius),
            (x: centerX + radius, z: centerZ + sqrt(3) * radius),
            (x: centerX + 2 * radius, z: centerZ)
        ]

        // Create seats with positions and directions
        return positions.enumerated().map { index, position in
            let seat = SpatialTemplateElement(
                position: SpatialPosition(x: position.x, y: 0, z: position.z)
            )
            seat.lookingAt(SpatialPosition(x: centerX - 2 * radius, y: 0, z: centerZ))
            return seat
        }
    }
}

Key Points from the Context:

• Positioning Seats: Seats are defined relative to the app's position using x and z offsets. For example, the first seat can be placed directly in front of the app with an x offset of 0 and a z offset of 4 meters. Subsequent seats can be positioned using trigonometric calculations to form an arc (Customize spatial Persona templates in SharePlay).
• Spacing: Ensure seats are at least 1 meter apart to avoid crowding (Customize spatial Persona templates in SharePlay).
• Seat Direction: Use the looking at method to orient each seat towards the leftmost seat (Customize spatial Persona templates in SharePlay).
