버튼을 클릭하여 사각형 안의 원을 클릭하십시오.

Question

게임을 만들려고합니다. 버튼으로 만든이 신경총을 만들어야합니다. 플레이어가 버튼을 클릭 할 때마다 누른 버튼 안에 작은 원이 표시됩니다. draw_circle 함수를 만들려고했지만 버튼 안에 액션 변수를 놓았을 때이 오류가 발생했습니다. 전역 이름 x가 정의되지 않았습니다.

Answer 1

당신이 x 또는 y에 대한 draw_circle 값을 제공하지 않는 button("GO!",150,450,100,50,green,bright_green,draw_circle) 라인에서

, 그래서 그들은 사실, 정의되지 않습니다. 이것들을 draw_circle 함수에 전달해야합니다. 당신의 button 기능의 내부

는 같은 draw_circle 아래로 인수를 전달합니다

if click[0] == 1 and action != None: 
     action(x, y)
