### Examples

```csharp
using UnityEngine;
using System.Collections;

[RequireComponent(typeof(LineRenderer))]
public class ExampleClass : MonoBehaviour
{
    private LineRenderer lr;

    void Start()
    {
        lr = GetComponent<LineRenderer>();
        lr.material = new Material(Shader.Find("Sprites/Default"));

        // Set some positions
        Vector3[] positions = new Vector3[3];
        positions[0] = new Vector3(-2.0f, -2.0f, 0.0f);
        positions[1] = new Vector3(0.0f,  2.0f, 0.0f);
        positions[2] = new Vector3(2.0f, -2.0f, 0.0f);
        lr.positionCount = positions.Length;
        lr.SetPositions(positions);

        // 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(Color.green, 0.0f), new GradientColorKey(Color.red, 1.0f) },
            new GradientAlphaKey[] { new GradientAlphaKey(alpha, 0.0f), new GradientAlphaKey(alpha, 1.0f) }
        );
        lr.colorGradient = gradient;
    }
}
