Presentation of the Finished calculator

Design and Implementation Process

My understanding of back -end seperation

1. Plan what function I need to add -- the requirement I need to accomplish
   such as if I want to add a sinsoidol function, so I need to learn how this function operating. Just like this function, first I need to click the sin button, and then click what radiant I want to calculate. So if I want to calculate value of sin(30 degree). I need first click sin and then 30 just I show in the previous video.
   So this is a very important thing, that is trying to understand how the calculator operating the different operation.
2. Accomplish the simple function of the easy operation --using the most easy way to achieve the goal will make the code better
   Such as my sin function code in the unity, I use the textMeshPro1.text to show the entering function and I also use a memory connected with a Mathf.Round to format the resulting results. And the function of Saving the data I will tell you after this part.

if(sin ==true)
{
    textMeshPro1.text += "=";
    memory = Mathf.Round(Mathf.Sin(memory2*Mathf.PI/180f)*100f)/100f;
    Save(index.ToString(), textMeshPro1.text += memory.ToString());
    CLEAR0();
    index++;
    sin = false;

Code explanation

3. Accomplish the requirement of doing the back-end seperation programming -- because for unity, the separation of the front and back ends in the code is not so clear. This is because unity's entire software already divides the UI and code into two separate blocks. So at the following, I will concerntrate on telling you how I save the data using the database.
   For the saving function, I use the particular funtion only exist in unity--PlayerPrefs.SetString(string key, string value); This is a funtion that unity can let the string key and string value save into unity's registry--just like the database in other apps. And Ans is a function that can call database data,Ansclear is a function that can clear all the data in the database.

public void Save(string formula, string result) 
    {    
        PlayerPrefs.SetString(formula,result);
        PlayerPrefs.Save();
    }
public void Ans()
{
    string[] ansfind = { "1","2","3","4","5","6","7","8","9","10"};
    
    if (PlayerPrefs.HasKey(ansfind[i]))
    {
        textMeshPro.text = PlayerPrefs.GetString(ansfind[i]);
        i++;
        Debug.Log(i);
    }
    
    if (i == 9)
    {
        i = 0;
    }
    
    
}
public void AnsClear()
{
    CLEAR();
    PlayerPrefs.DeleteAll();
}

Summary

For this assignment 2, I find that I have learn a new knowledge that in th eunity --database and how to memory the previous data and call out theis data. This also enabled me to discover how to cache previous game data in unity games, and the use of function this time gave me a new idea on how to write function, which will be of great help to my further study.
