Examples
using UnityEngine;using System.Collections;[RequireComponent(typeof(TrailRenderer))]public class ExampleClass : MonoBehaviour{ public float width = 1.0f; public bool useCurve = true; private TrailRenderer tr; void Start() { tr = GetComponent<TrailRenderer>(); tr.material = new Material(Shader.Find("Sprites/Default")); } 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); } tr.widthCurve = curve; tr.widthMultiplier = width; tr.transform.position = new Vector3(Mathf.Sin(Time.time * 1.51f) * 7.0f, Mathf.Cos(Time.time * 1.27f) * 4.0f, 0.0f); } 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"); }}
