Unity实现3D模型自动分解

将代码挂载在装配模型上，并加入Toggle控制即可实现，效果如图所示

具体代码如下：

using UnityEngine;

using System.Collections.Generic;

using System;


[Serializable]

public class SubMeshes

    public MeshRenderer meshRenderer;

    public Vector3 originalPosition;

    public List<SubMeshes> childMeshRenderers;

    bool isInExplodedView = false;

    public float explosionSpeed = 0.1f;

    bool isMoving = false;


    #endregion


    #region UnityFunctions


    private void Awake()

    {

        childMeshRenderers = new List<SubMeshes>();


        foreach (var item in GetComponentsInChildren<MeshRenderer>())

        {

            mesh.meshRenderer = item;

            mesh.originalPosition = item.transform.position;

            mesh.explodedPosition = item.bounds.center * 1.5f;

            childMeshRenderers.Add(mesh);

        }

    }

                    if (Vector3.Distance(item.meshRenderer.transform.position, item.explodedPosition) < 0.001f)

                    }

                    if (Vector3.Distance(item.meshRenderer.transform.position, item.originalPosition) < 0.001f)

                    }

                }

            }

        }

    }


    #endregion
