scn 노드 내에서 여러 물질간에 충돌 탐지를 시도하고 있습니다. 큐브에는 6 가지 재료/색상과 볼이 있습니다. 동일하고 다른 색깔의 충돌을 감지하고 싶지만 각 자료에 다른 카테고리를 적용하는 방법을 모릅니다.scn 노드 내에서 다른 물질에 충돌 감지를 얻는 방법

class GameViewController: UIViewController, SCNPhysicsContactDelegate {
나중에 큐브의 다른면에 지정할 범주를 만들 수 있습니까?

에 다른 카테고리를 추가하는 것은 아마도이 문제를 단순화 할 수있는 방법이 일치하는 색상의 한정자로 볼 및 큐브 충돌을 감지 할 수 있습니까?
감사합니다.
연락처를 검색 할 때 공의 색상과 얼굴의 색상을 비교하는 것이 가장 좋은 이유는 무엇입니까? 이게 너 니가 보낸거야? –
예, 정확히 구현 했습니까? – spapp
