I have ModelEntity in SwiftUI and it moves. But the problem is: when adding generateCollisionShape
method, it doesn't move anymore.
I want a collision effect as well as moving entity how can I attain both?
modelEntityClone.generateCollisionShapes(recursive: true)
modelEntityClone.physicsBody = PhysicsBodyComponent(massProperties: .default,
material: .default,
mode: .dynamic)
Hope this trick definitely helps. This physics lasts forever. ))
struct ARViewContainer: UIViewRepresentable {
let ball = ModelEntity(mesh: .generateSphere(radius: 0.5))
let anchor = AnchorEntity()
func makeUIView(context: Context) -> ARView {
let arView = ARView(frame: .zero)
ball.physicsBody = .init()
ball.physicsBody?.massProperties.mass = 0
ball.physicsMotion = .init()
ball.physicsMotion?.linearVelocity.x = 5.0
ball.physicsMotion?.angularVelocity.z = -.pi
ball.position.x = -4.0
ball.generateCollisionShapes(recursive: true)
anchor.addChild(ball)
anchor.position.z = -3.0
arView.scene.addAnchor(anchor)
return arView
}
func updateUIView(_ uiView: ARView, context: Context) { }
}
