나 자신과 내 친구에게 Stackoverflow는 코드와 관련하여 질문 할 곳이라고 말했습니다. :)Cocos2d, 스프라이트를 터치 위치로 이동
우리는 Objective-C, Xcode 및 Cocos2d를 처음 접했고 우리의 지식을 향상시키기 위해 간단한 작업을 완료하려고합니다.
아래의 코드를 살펴보면 Ant 개체를 만들어 화면에 배치했습니다. 우리는 이제 터치 위치를 사용하여 사용자가 터치하는 위치로 개미를 이동하려고합니다.
정확한 방법은 무엇인지 확실하지 않습니다. 현재 우리는 수업을 작성하지 않으므로 모든 코드를 한 곳에 모으고 화면에있는 개미를 터치 위치로 가져 오는 방법을 알 수 없습니다.
아무도 도와 줄 수 있습니까?
