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. Note that positionCount must be called before SetPositions. Also SetPositions ignores points with indices beyond positionCount.

See Also: positionCount property, SetPosition function.

// A simple 2 color gradient with a fixed alpha of 1.0f. float alpha = 1.0f; Gradient gradient = new Gradient(); gradient.SetKeys( new GradientColorKey[] { new GradientColorKey(c1, 0.0f), new GradientColorKey(c2, 1.0f) }, new GradientAlphaKey[] { new GradientAlphaKey(alpha, 0.0f), new GradientAlphaKey(alpha, 1.0f) } ); lineRenderer.colorGradient = gradient; }
