UE4 委托应用

1.单个委托 (测试只能绑定一个方法，绑定多个方法时执行最后一个绑定方法)

声明：DECLARE_DELEGATE_OneParam(MyDelegate, FVector);

MyDelegate delegate_CameraMove;

执行:

delegate_CameraMove.Excute(offset);

绑定：

delegate_CameraMove.BindUObject(this, &AGodCameraCode::CameraMove);

移除：

delegate_CameraMove.UnBind();

2.多播委托

声明： DECLARE_MULTICAST_DELEGATE_OneParam(OnMoveCameraDelegate, FVector);
 OnMoveCameraDelegate _Delegate_MoveCamera;

执行：_Delegate_MoveCamera.Broadcast(mousePos);

添加：cameraMoveDelegate = _Delegate_MoveCamera.AddUObject(this, &AGodCameraCode::CameraMove);

移除：_Delegate_MoveCamera.Remove(cameraMoveDelegate);
