public AnimationCurve widthCurve;

Description

Set the curve describing the width of the line at various points along its length.

This property is multiplied by LineRenderer.widthMultiplier to get the final width of the line.

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(LineRenderer))] public class ExampleClass : MonoBehaviour { public float width = 1.0f; public bool useCurve = true; 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); }

void Update() { AnimationCurve curve = new AnimationCurve(); if (useCurve) { curve.AddKey(0.0f, 0.0f); curve.AddKey(1.0f, 1.0f); } else { curve.AddKey(0.0f, 1.0f); curve.AddKey(1.0f, 1.0f); }

lr.widthCurve = curve; lr.widthMultiplier = width; }

void OnGUI() { GUI.Label(new Rect(25, 20, 200, 30), "Width"); width = GUI.HorizontalSlider(new Rect(125, 25, 200, 30), width, 0.1f, 1.0f); useCurve = GUI.Toggle(new Rect(25, 65, 200, 30), useCurve, "Use Curve"); } }
