Debug.DrawLine

파라미터

설명

Draws a line between specified start and end points.

The line will be drawn in the scene view of the editor. If gizmo drawing is enabled in the game view, the line will also be drawn there. 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.
