选中物体反馈效果——描边

Outline卡通描边

Shader学习：描边Outline初步

前言鸽了好久的描边，其实一方面自己也是才刚开始学习，不像大佬一样信手捏来，只能跟着各种教程学。另一方面，做出来的效果一直和想象中的有点差距，虽然本人尝试了很多的教程，到目前为止的效果勉强达到及格线吧…

1.用脚本OutlineScript +shader

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class OutlineScript : MonoBehaviour
{
    [SerializeField] private Material outlineMaterial;
    [SerializeField] private float outlineScaleFactor;
    [SerializeField] private Color outlineColor;
    private Renderer outlineRenderer;
    
    void Start()
    {
        outlineRenderer = CreateOutline(outlineMaterial, outlineScaleFactor, outlineColor);
        outlineRenderer.enabled = true;
    }

    Renderer CreateOutline(Material outlineMat, float scaleFactor, Color color) 
    {
        GameObject outlineObject = Instantiate(this.gameObject, transform.position, transform.rotation, transform);
        Renderer rend = outlineObject.GetComponent<Renderer>();

        rend.material = outlineMat;
        rend.material.SetColor("_OutlineColor", color);
        rend.material.SetFloat("_Scale", scaleFactor);
        rend.shadowCastingMode = UnityEngine.Rendering.ShadowCastingMode.Off;

        outlineObject.GetComponent<OutlineScript>().enabled = false;
        outlineObject.GetComponent<Collider>().enabled = false;

        rend.enabled = false;

        return rend;
    }
}

2.shader 用双pass在顶点法线往外扩，
