Unity Puzzle Game : TEN by TEN

Drag and make Square to cover Numbers. When Dragged up and sum of Numbers become " 10 " that Numbers disappear. time limit is 60s and the removed numbers of Numbers(Bubbles) add to Score.

In Details

Board Setting

.
.
private List<GameObject> Bubbles;
.
.
void SettingBoard(){
  for (float i = 4; i > -4; i -= 0.8f)
      {
        for (float j = -7; j < 8; j += 0.8f)
        {
          GameObject bubble = (GameObject)Instantiate(NumPrefab[Random.Range(0, 9)],
          new Vector2(j, i),
          Quaternion.identity);
          Bubbles.Add(bubble);
        }
      }
}

• Make a Bubble(Number-Block) from prefab resources randomly and add to List to supervise them
• Each Bubbles' size are same to Unit size 4. So I made a virtual grid position and arrange them to each position
• Thought that float 0.8 can be replaced with size of Prefab

Mouse Dragging Effect

.
.
private RectTransform SelectField;
.
.
void MouseDrag(Vector2 curMousePos)
  {
    SelectField.gameObject.SetActive(true);
    float width = curMousePos.x - MouseInit.x;
    float height = curMousePos.y - MouseInit.y;

    SelectField.sizeDelta = new Vector2(Mathf.Abs(width), Mathf.Abs(height));
    SelectField.anchoredPosition = MouseInit + new Vector2(width / 2, height / 2);
  }

• Make a Canvs-Image, resizing and repositioning at first mouse click and after mouse movement.
• Position a Image at Left-Bottom pivot and calculate its width, height, center pivot position in Update func

Calculate Bubbles

private void SelectBubbles(Vector2 curMousePos)
  {
    Vector2 max, min;
    Color32 preColor = new Color32(243, 125, 125, 255);
    Color32 postColor = new Color32(96, 149, 245, 255);
    foreach (GameObject el in Bubbles)
    {
      Vector2 pos = el.transform.position;
      if (startSelectPos.x > curMousePos.x)
      {
        max.x = startSelectPos.x;
        min.x = curMousePos.x;
      }
      else
      {
        max.x = curMousePos.x;
        min.x = startSelectPos.x;
      }
      if (startSelectPos.y > curMousePos.y)
      {
        max.y = startSelectPos.y;
        min.y = curMousePos.y;
      }
      else
      {
        max.y = curMousePos.y;
        min.y = startSelectPos.y;
      }

      if (pos.x >= min.x && pos.x <= max.x
      && pos.y >= min.y && pos.y <= max.y)
      {
        el.transform.localScale = Vector3.Lerp(el.transform.localScale, new Vector3(5.5f, 5.5f, 0), Time.deltaTime * 10);
        el.transform.GetChild(0).GetComponent<SpriteRenderer>().color = postColor;

        if (!CheckDict.ContainsKey(el))
        {
          CheckDict.Add(el, int.Parse(el.name.Split('_')[1].Split('(')[0]));
        }
      }
      else
      {
        el.transform.localScale = Vector3.Lerp(el.transform.localScale, new Vector3(5, 5, 0), Time.deltaTime * 10);
        el.transform.GetChild(0).GetComponent<SpriteRenderer>().color = preColor;
      }
    }
  }

Bubble Select Judgement

Bubble selection judgement needed 4-way calculation : Mouse Click from LEFT-TOP, LEFT-BOTTOM, RIGHT-TOP, RIGHT-BOTTOM So I made 4 conditional statement for calculate them.

• if Bubbles are in that selection box, it change its color in Lerp and Add to CheckDict Dictionary.
• CheckDict Dictionary used for Is Bubble's sum 10 or not
• DUPLICATE CHECK : used Dictionary<GameObject, int> CheckDict. GameObject has its soley own name so I use it for KEY and Value as that Object's number. So it can prevent Duplicated selection issues.

Sum of Bubbles Calculate

.
.
void Update(){
...
...
  if (Input.GetMouseButtonUp(0))
  {
    SelectField.gameObject.SetActive(false);
    UndoBubbles();


    foreach (KeyValuePair<GameObject, int> el in CheckDict)
    {
      sum += CheckDict[el.Key];
    }
    Debug.Log(sum);
    if (sum == GoalNum)
    {
      foreach (KeyValuePair<GameObject, int> el in CheckDict)
      {
        Destroy(el.Key);
        Bubbles.Remove(el.Key);
      }
      score += CheckDict.Count;
      ScoreTMPro.text = score.ToString();
    }
    sum = 0;
  }
.
.

• Calcualte only when after MouseButton Up
• looping Checkdict elememt for its sum and if sum is 10, Destroy Objects and remove them in Bubble-List
