示例1: Update
public void Update(IMyEntity missile)
{
LineSegment line = new LineSegment(entity.GetPosition(), entity.GetPosition() + entity.WorldMatrix.Forward * 1e6f);
position = line.ClosestPoint(missile.GetPosition()) + missile.Physics.LinearVelocity;
linearVelocity = entity.WorldMatrix.Forward * missile.Physics.LinearVelocity.Length();
