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

パラメーター

startラインの開始位置(ワールド座標)
endラインの終了位置(ワールド座標)
colorラインの色
durationラインを表示する時間(秒単位)
depthTestラインがカメラから近いオブジェクトによって隠された場合にラインを隠すかどうか

説明

指定した開始位置と終了位置の間にラインを描画します。

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.

void FixedUpdate() { // always draw a 5-unit colored line from the origin Color color = new Color(q, q, 1.0f); Debug.DrawLine(Vector3.zero, new Vector3(0, 5, 0), color); q = q + 0.01f;

if (q > 1.0f) { q = 0.0f; } } }
