public void SetPosition(int index, Vector3 position)

Parameters

index

int
Which position to set.

position

Vector3
The new position.

Remarks

Consider using LineRenderer.SetPositions instead, if setting multiple positions, as it is much faster than making individual function calls for each position.
Additional Resources: LineRenderer.positionCount property.

Examples

using UnityEngine;using System.Collections;public class ExampleClass : MonoBehaviour{    // Creates a line renderer that follows a Sin() function    // and animates it.    public Color c1 = Color.yellow;    public Color c2 = Color.red;    public int lengthOfLineRenderer = 20;    void Start()    {        LineRenderer lineRenderer = gameObject.AddComponent<LineRenderer>();        lineRenderer.material = new Material(Shader.Find("Sprites/Default"));        lineRenderer.widthMultiplier = 0.2f;        lineRenderer.positionCount = lengthOfLineRenderer;        // 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;    }    void Update()    {        LineRenderer lineRenderer = GetComponent<LineRenderer>();        var t = Time.time;        for (int i = 0; i < lengthOfLineRenderer; i++)        {            lineRenderer.SetPosition(i, new Vector3(i * 0.5f, Mathf.Sin(i + t), 0.0f));        }    }}
