Hey! I'm facing an issue with Equipment collision when adding and moving TabletopKit equipment with different pose rotations.
Let me share a very simple TabletopKit setup as an example:
Table
struct Table: Tabletop {
var shape: TabletopShape = .rectangular(width: 1, height: 1, thickness: 0.01)
var id: EquipmentIdentifier = .tableID
}
Board
struct Board: Equipment {
let id: EquipmentIdentifier = .boardID
var initialState: BaseEquipmentState {
.init(
parentID: .tableID,
seatControl: .restricted([]),
pose: .init(position: .init(), rotation: .zero),
boundingBox: .init(center: .zero, size: .init(1.0, 0, 1.0))
)
}
}
Equipment
struct Object: EntityEquipment {
var id: ID
var size: SIMD2<Float>
var position: SIMD2<Double>
var rotation: Float
var entity: Entity
var initialState: BaseEquipmentState
init(id: Int, size: SIMD2<Float>, position: SIMD2<Double>, rotation: Float) {
self.id = EquipmentIdentifier(id)
self.size = size
self.position = position
self.rotation = rotation
self.entity = objectEntity
self.initialState = .init(
parentID: .boardID,
seatControl: .any,
pose: .init(
position: .init(x: position.x, z: position.y),
rotation: .degrees(Double(rotation))
),
entity: entity
)
}
}
Setup
class GameSetup {
var setup: TableSetup
init(root: Entity) {
setup = TableSetup(tabletop: Table())
setup.add(equipment: Board())
setup.add(seat: PlayerSeat())
let object1 = Object(
id: 2,
size: .init(x: 0.1, y: 0.1),
position: .init(x: 0.1, y: -0.1),
rotation: 0
)
let object2 = Object(
id: 3,
size: .init(x: 0.2, y: 0.1),
position: .init(x: -0.1, y: -0.1),
rotation: 90
)
setup.add(equipment: object1)
setup.add(equipment: object2)
}
}
The issue
When I add two equipment entities with different rotation poses, the collisions between them behave oddly. If one is 90º and the other 0º, for example, the former will intersect with the latter as if its bounding box was not rotated as you can see below:
But if both equipment have the example rotation (e.g. 0 or 90º), though, then there's no collision issue at all, which seems to indicate their bounding box were correctly rotated:
I'd really appreciate some help understanding if this is a bug or if I'm just missing something.
Thanks in advance!
