To make Potion Profiteer, we made the choice of using the unity engine over Unreal Engine 5 as The game has 4 coders on this project. As a result using Unity means that we can work more collaboratively using GitHub. Thanks to my introduction to Unity and C# programming, it made me one of the more experienced, leader coders of the 4 of us.

In this project I have been tasked with coding the storefront. I used computational thinking to help code this as it helps to understand complex problems and create solutions. Therefore the first thing I did was decompose the problem by looking at the design draft. By using decomposition I could more easily tackle the code by dividing it into more understandable chunks. I think this was very useful as it helped to solidify my understanding on how to tackle the code and gave me a more solid understanding on what I am doing so I can therefore do it to a higher standard. However, one disadvantage is that this was a very simple decomposition and a may have missed things.

From this division of the problem I have decided to work on the customer sprite first. This is because I feel it is the main function of the storefront. I decided to use a singular customer sprite that switched images to the different images of customers in a switch statement. I used a switch statement for two reasons. The first that it is more efficient than an if statement as the code will only read the case it needs rather than all the if statements. The second as it would be easier to randomise as a switch case, as random customers was one of the issues highlighted in the original decomposition.

During this session I also tried to randomise the value of 'num' in the switch case. This proved to be more difficult then originally anticipated and so for the time being I left it as a simple switch case where 'num' increased by 1 at each key press and made sure that when it defaulted, 'num' returned back to 0. I did this because I needed a way to bug check that the rest of my sprite change code was working and so I needed something to initiate that switch case.

      using UnityEngine;
      //using System;
      
      public class CustomerSpriteChange : MonoBehaviour
      {
          public Sprite sp1;
          public Sprite sp2;
          public Sprite sp3;
          public Sprite sp4;
          public Sprite sp5;
          // will make efficient later //
      
          int num = 0;
          //Random rnd = new Random();
      
          // Start is called before the first frame update //
          void Start()
          {
              
          }
      
          // Update is called once per frame
          void Update()
          {
              if (Input.GetMouseButtonDown(0))
              {
                  num++;
              }
      
              //int num = rnd.Next(0,3);
              // havent figured out how to randomise yet so for now customers have an order, this should be temp //
              switch (num)
              {
                  case 0:
                      GetComponentSpriteRenderer>().sprite = sp1;
                      //num++;
                      break;
                  case 1:
                      GetComponentSpriteRenderer>().sprite = sp2;
                      //num++;
                      break;
                  case 2:
                      GetComponentSpriteRenderer>().sprite = sp3;
                      //num++;
                      break;
                  case 3:
                      GetComponentSpriteRenderer>().sprite = sp4;
                      //num++;
                      break;
                  case 4:
                      GetComponentSpriteRenderer>().sprite = sp5;
                      break;
                  default:
                      num = 0;
                      break;
              }
          }
      }

To improve this code I could combine the "Public Sprite" initiations to be one line of code instead of 5. The void Start() can also be removed as it is unused in this class. Next I intend to make expand on this code to add a potion to interact with and a text to ask for the potion.
