Unity Script Reference – Debug.DrawLine

Debug.DrawLine

static function DrawLine (start : Vector3, end : Vector3, color : Color = Color.white, duration : float = 0.0f) : void

Description

Draws a line from the point start to end with color for a duration of time. If duration is 0 then the line is rendered 1 frame.

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.

JavaScripts

// Frame update example: Draws a red line from the world-space origin to the point (1, 0, 0) for 1 frame.
function Update () {
Debug.DrawLine (Vector3.zero, Vector3 (1, 0, 0), Color.red);
}

public class example : MonoBehaviour {
void Update() {
Debug.DrawLine(Vector3.zero, new Vector3(1, 0, 0), Color.red);
}
