2 消融特效实现 创建 Unlit Shader Graph重命名为 DissolveEffect编辑如下。 其中Alpha 测试需要在 Graph Settings 中开启如下。 为实现点击消失效果需要编写脚本如下。 DieController.cs
using UnityEngine;public class DieController : MonoBehaviour {private RaycastHit hit; // 碰撞信息private void Start() {hit new RaycastHit();}private void Update() {if (Input.GetMouseButtonUp(0)) {GameObject hitObj GetHitObj();if (hitObj ! null) {GameObject rootObj GetRootObj(hitObj);rootObj.AddComponentDissolveEffect();}}}private GameObject GetHitObj() { // 获取屏幕射线碰撞的物体Ray ray Camera.main.ScreenPointToRay(Input.mousePosition);if (Physics.Raycast(ray, out hit)) {return hit.collider.gameObject;}return null;}private GameObject GetRootObj(GameObject obj) { // 获取根对象while (obj.transform.parent ! null obj.layer obj.transform.parent.gameObject.layer) {obj obj.transform.parent.gameObject;}return obj;}
} DissolveEffect.cs
using UnityEngine;[DisallowMultipleComponent] // 不允许在同一对象上挂载多个该组件
public class DissolveEffect : MonoBehaviour {private Renderer[] renderers; // 渲染器private Material dissolveMat; // 消融材质private float burnSpeed 0.25f; // 燃烧速度private float burnAmount 0; // 燃烧量, 值越大模型镂空的越多private void Awake() {dissolveMat Resources.LoadMaterial(DissolveMat);renderers GetComponentsInChildrenRenderer();}private void OnEnable() {foreach (Renderer renderer in renderers) {Material[] materials renderer.sharedMaterials;Material[] dissolveMaterials new Material[materials.Length];for (int i 0; i materials.Length; i) {Material newMaterial new Material(dissolveMat);SetTexture(materials[i], newMaterial);SetColor(materials[i], newMaterial);newMaterial.SetFloat(_BurnAmount, 0);dissolveMaterials[i] newMaterial;}renderer.sharedMaterials dissolveMaterials;}}private void Update() {burnAmount Time.deltaTime * burnSpeed;foreach (Renderer renderer in renderers) {Material[] materials renderer.sharedMaterials;foreach (Material material in materials) {material.SetFloat(_BurnAmount, burnAmount);}}if (burnAmount 1f) {Destroy(gameObject);}}private void SetTexture(Material oldMaterial, Material newMaterial) { // 设置材质if (oldMaterial.HasTexture(_MainTex)) {Texture texture oldMaterial.GetTexture(_MainTex);newMaterial.SetTexture(_MainTex, texture);}}private void SetColor(Material oldMaterial, Material newMaterial) { // 设置颜色Color color Color.white;if (oldMaterial.HasColor(_Color)) {color oldMaterial.GetColor(_Color);}newMaterial.SetColor(_Color, color);}
} 运行效果如下。
