Unity模拟零件拆解组装

零、最终效果

一、资源准备

1、iTween插件安装

地址：https://assetstore.unity.com/packages/tools/animation/itween-84

2、Unity版本

Unity 2022.3.26f1c1

二、主要原理

通过将零件的位置进行平滑移动，从而实现零件的拆解和组装

三、相关代码

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

public class SplitAndMerge : MonoBehaviour
{
	public GameObject[] startPos;
	public GameObject[] endPos;
	public Vector3[] temp;
	// Start is called before the first frame update
	void Start()
    {
		temp = new Vector3[startPos.Length];
		for (int i = 0; i < temp.Length; i++)
		{
			temp[i] = startPos[i].transform.position;
		}
    }

    // Update is called once per frame
    void Update()
    {
		if (Input.GetKeyDown(KeyCode.Alpha1))
		{
			Split();
		}
		if (Input.GetKeyDown(KeyCode.Alpha3))
		{
			Merge();
		}
    }


	private void Split()
	{
		for (int i = 0; i < endPos.Length; i++)
		{
			MachineInit(startPos[i], endPos[i].transform.position);
		}
	}
	private void Merge()
	{
		for (int i = 0; i < endPos.Length; i++)
		{
			MachineInit(startPos[i], temp[i]);
		}
	}

	public void MachineInit(GameObject obj, Vector3 vec)
	{
		iTween.MoveTo(obj, iTween.Hash(
			"position", vec,
			"Time", 0.3f,
			"easetype", iTween.EaseType.easeInOutQuad,
			"space", Space.Self,
			"looptype", iTween.LoopType.none
			));
	}
}
