第Unity使用多態(tài)制作計算器功能本文實例為大家分享了Unity使用多態(tài)制作計算器，供大家參考，具體內(nèi)容如下

Unity中需要的組件

在Unity中創(chuàng)建兩個InputField，一個Dropdown，一個Button和一個Text

創(chuàng)建腳本文件

計算父類

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

publicclassJsq:MonoBehaviour

publicabstractclassCalculate

publicfloatNumber1

get;

set;

publicfloatNumber2

get;

set;

publicabstractfloatCompute();

}

加法

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

publicclassAddition:Jsq.Calculate

///summary

///實現(xiàn)父類計算方法

////summary

///returns加法計算結(jié)果/returns

publicoverridefloatCompute()

returnNumber1+Number2;

}

減法

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

publicclassSubtraction:Jsq.Calculate

///summary

///實現(xiàn)父類計算方法

////summary

///returns減法計算結(jié)果/returns

publicoverridefloatCompute()

returnNumber1-Number2;

}

乘法

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

publicclassMultiplication:Jsq.Calculate

publicoverridefloatCompute()

returnNumber1*Number2;

}

除法

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

publicclassNewBehaviourScript:Jsq.Calculate

publicoverridefloatCompute()

returnNumber1/Number2;

}

等于號按鈕

usingSystem.Collections;

usingSystem.Collections.Generic;

usingUnityEngine;

usingUnityEngine.UI;

usingSystem;

publicclassEqualBtn:Jsq

publicTexttxt_Number1;

publicTexttxt_Number2;

publicTextcbb_Operator;

publicTextlab_Result;

publicvoidbtn_click()

//獲取兩個參數(shù)

floatnumber1=Convert.ToSingle(txt_Number1.text.Trim());

floatnumber2=Convert.ToSingle(txt_Number2.text.Trim());

//獲取運算符

stringoperation=cbb_Operator.text.Trim();

//通過運算符，返回父類類型

Calculatecalculate=GetCalculateResult(operation);

calculate.Number1=number1;

calculate.Number2=number2;

//利用多態(tài)返回運算結(jié)果

stringresult=calculate.Compute().ToString();

this.lab_Result.text=result;

privateCalculateGetCalculateResult(stringoperation)

Calculatecalculate=null;

switch(operation)

case"+":

calculate=newAddition();

break;

case"-":

calculate=newSubtraction();

break;

case"*":

calculate=newMultiplication();

break;

case"/":

calculate=newDivision();

break;

returncalculate;

}

將等于號按鈕腳本賦給Canvas組件

再將對應的組件拉進去：順序分別是第一個InputField里的text（注意都是text），第二個InputField里的text，然后是Drop
