Unity插件 使用Ezy-Slice插件实现模型切割效果

去网上下载Ezy-Slice插件

工具类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using EzySlice;public static class SliceTools
{public static T FaultoleranceGetComponent<T>(GameObject go) where T : Component{if (go != null){T component = go.GetComponent<T>();if (component == null){component = go.AddComponent<T>();}return component;}return null;}public static SlicedHull SliceObject(GameObject obj, Vector3 positon, Vector3 normal,Material crossSectionMaterial = null){// slice the provided object using the transforms of this objectif (obj.GetComponent<MeshFilter>() == null)return null;return obj.Slice(positon, normal, crossSectionMaterial);}
}

核心类

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using EzySlice;public class Slice : MonoBehaviour
{public Material sliceMat;void Start(){}void Update(){}private void OnTriggerEnter(Collider other){GameObject source = other.gameObject;if (source.tag == Tag.player){//Debug.Log(other.gameObject.tag);            //将Souce切割，传入的第一个参数为切割的位置（即刀片的位置），传入的第二个参数为切割面的法向量（即刀片表面的法向量）            SlicedHull hull = SliceTools.SliceObject(source, transform.position, transform.forward, sliceMat);//Debug.Log(hull);if (hull != null){                //创建把source切割以后的上半部分物体GameObject uperHull = hull.CreateUpperHull(source, sliceMat);SliceObject(uperHull);//创建把source切割以后的下半部分物体GameObject lowerhull = hull.CreateLowerHull(source, sliceMat);SliceObject(lowerhull);//-----------处理原物体-------------------Destroy(source);}}}void SliceObject(GameObject shatteredObject){if (shatteredObject == null){return;}MeshCollider mcUper = SliceTools.FaultoleranceGetComponent<MeshCollider>(shatteredObject);if (mcUper != null){mcUper.sharedMesh = shatteredObject.GetComponent<MeshFilter>().mesh;mcUper.convex = true;}Rigidbody rdUper = SliceTools.FaultoleranceGetComponent<Rigidbody>(shatteredObject);if (rdUper != null){rdUper.useGravity = true;//rdUper.constraints = RigidbodyConstraints.FreezePositionZ;//rdUper.mass = 100;}SliceTools.FaultoleranceGetComponent<MoveObj>(shatteredObject);shatteredObject.tag = Tag.player;}
}

Slice是切片，切片上添加Slice脚本

Cube是模型，添加刚体组件，模型除自身材质外，还需要添加切割的材质。
