룰렛 휠의 특정 번호에서 공을 멈추는 법

Question

저는 WPF와 C# .NET에서 룰렛 게임을 만들고 있습니다. 나는 바퀴를 성공적으로 돌린다. 그러나 나는 공이 멈추고있는 특정한 가치를 얻기 위해 붙어있다.

아무도 내가 내가 볼이 정지되는 값을 얻을 수있는 방법 Expression Blend를 (아래 코드)를 사용하여 기본 애니메이션을 만들었습니다 중 하나

의 값을 얻기 위해 적용 할 수있는 논리의 종류 나에게 도움이 될 수 있습니다.

Answer 1

코드에서

<RotateTransform x:Name="wheelAngle" /> 

변환

<Storyboard x:Key="spinWheel" Completed="Storyboard_Completed"> 

당신의 회전에 이름을 추가하여 스토리 보드에 이벤트 처리기를 추가 뒤에 약간의 수학은 어디에 공을 밖으로 작동합니까 wheelAngle.Angle 및 ballAngle.Angle입니다.
