GraphicsContext의 fillRect 메서드를 사용할 때. aA 사각형은 Canvas tilesetCanvas에 그려집니다. 그런 다음 setStroke 및 strokeLine 메서드를 사용하지만이 메서드는 fillRect 메서드와 같은 캔버스를 업데이트하지 않습니다. Canvas를 업데이트하는 특정 방법이 있습니까? 아니면 setStroke 및 strokeLine 메서드를 잘못 사용하고 있습니까?GraphicsContext strokeLine 메서드가 캔버스에 예상대로 그려지지 않습니다.

문제를 재현하는 데 정말로 도움이되는 코드가 많지만 문제가있는 곳을 사람들이 알기가 정말 어렵습니다. 문제가있는 곳을 더 잘 설명하도록 질문을 다시 작성할 수는 있습니다. – Adrian
