public void SetPositions (Vector3[] positions);

파라미터

positions The array of positions to set.

설명

Set the positions of all vertices in the line.

This method is preferred to SetPosition when setting all positions, as it is more efficient to set all positions using a single command than to set each position individually.

See Also: numPositions property.
