本文介绍了如何利用Unity游戏引擎和C#编程语言实现一个简单的计算器功能，通过代码段展示了具体的实现过程。

代码段

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

public class Computer : MonoBehaviour
{
    private Text TextComputeProcess;//计算过程
    private Text TextComputeResult;//计算结果

    private Button BtnReset;
    private Button BtnDelete;
    private Button BtnAdd;
    private Button BtnSub;
    private Button BtnMul;
    private Button BtnDiv;
    private Button BtnEqual;

    private Button Btn0, Btn1, Btn2, Btn3, Btn4, Btn5, Btn6, Btn7, Btn8, Btn9;
    private Button BtnPoint, BtnPm;

    private string calculateString = "";//计算数
    private string m_operation = "";//操作数
    private bool pmState = false;//正负状态
    private int RUNSTATE = 0;//0 默认 1 输入数字 2 输入操作符 3 输入操作符再输入数字 4 计算结果后

    void Start()
    {
        //结果显示
        TextComputeProcess = GameObject.Find("Canvas/Background/Image/TextComputeProcess").GetComponent<Text>();
        TextComputeResult = GameObject.Find("Canvas/Background/Image/TextComputeResult").GetComponent<Text>();
        TextComputeResult.text = "0";
        RUNSTATE = 0;

        //操作
        BtnReset = GameObject.Find("Canvas/Background/重置").GetComponent<Button>();
        BtnReset.onClick.AddListener(() => OperationDispose("CE"));
        BtnDelete = GameObject.Find("Canvas/Background/删除").GetComponent<Button>();
        BtnDelete.onClick.AddListener(() => OperationDispose("Del"));

        //加减乘除
        BtnAdd = GameObject.Find("Canvas/Background/加").GetComponent<Button>();
        BtnAdd.onClick.AddListener(() => OperationDispose("+"));
        BtnSub = GameObject.Find("Canvas/Background/减").GetComponent<Button>();
        BtnSub.onClick.AddListener(() => OperationDispose("-"));
        BtnMul = GameObject.Find("Canvas/Background/乘").GetComponent<Button>();
        BtnMul.onClick.AddListener(() => OperationDispose("*"));
        BtnDiv = GameObject.Find("Canvas/Background/除").GetComponent<Button>();
        BtnDiv.onClick.AddListener(() => OperationDispose("/"));
        BtnEqual = GameObject.Find("Canvas/Background/等于").GetComponent<But
