public static void DrawLine (Vector3 start, Vector3 end, Color color= Color.white, float duration= 0.0f, bool depthTest= true);


start@param start Точка в мировом пространстве, откуда начнётся линия.
end@param end Точка в мировом пространстве, в которой линия закончится.
color@param color Цвет линии.
duration@param duration Время отображения линии.
depthTest@param depthTest Будет ли линия перекрываться более близкими к камере объетами?


Рисует линию между двумя указанными точками.

The line will be drawn in the Game view of the editor when the game is running and the gizmo drawing is enabled. The line will also be drawn in the Scene when it is visible in the Game view. Leave the game running and showing the line. Switch to the Scene view and the line will be visible.

The duration is the time (in seconds) for which the line will be visible after it is first displayed. A duration of zero shows the line for just one frame.

Note: This is for debugging playmode only. Editor gizmos should be drawn with Gizmos.Drawline or Handles.DrawLine instead.
