[Unity] 숫자 올라가는 효과 ( 숫자 카운팅 )

안녕하세요

게임에서 재화를 획득하거나 게임 결과를 나타낼 때 숫자가 순차적으로 올라가는 효과가 있는데, 그걸 구현해 보도록 하겠습니다.

 

 

1. update함수를 통해서 구현

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
 
public class Counter : MonoBehaviour
{
    TMP_Text textCount;
 
    int nTargetPoint = 1000;
    float fCount = 0f;
 
    const float SPEED = 100f;
 
    void Start()
    {
        textCount = GameObject.Find("Canvas/CountText").GetComponent<TMP_Text>();
 
    }
 
    void Update()
    {
        fCount += Time.deltaTime * SPEED;
 
        if(fCount <= nTargetPoint)
        {
            textCount.text = fCount.ToString("F0");
        }
    }
}
 

 

2. 코루틴으로 구현

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
 
public class Counter : MonoBehaviour
{
    TMP_Text textCount;
 
 
    const float SPEED = 100f;
 
    void Start()
    {
        textCount = GameObject.Find("Canvas/CountText").GetComponent<TMP_Text>();
        StartCoroutine(numCount(1000f));
    }
 
    IEnumerator numCount(float fTargetNum)
    {
        float fCount = 0;
 
        while (fCount <= fTargetNum)
        {
            fCount += Time.deltaTime * SPEED;
            textCount.text = fCount.ToString("F0");
            yield return null;
        }
 
        textCount.text = fTargetNum.ToString("F0");
    }
 
}
 

 

3. 코루틴에서 WaitForSeconds 사용

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
 
public class Counter : MonoBehaviour
{
    TMP_Text textCount;
 
 
    void Start()
    {
        textCount = GameObject.Find("Canvas/CountText").GetComponent<TMP_Text>();
        StartCoroutine(numCount(1000));
    }
 
    IEnumerator numCount(int nTargetNum)
    {
        float nCount = 0;
 
        while (nCount <= nTargetNum)
        {
            nCount++;
            textCount.text = nCount.ToString();
            yield return new WaitForSeconds(0.01f);
        }
 
        textCount.text = nTargetNum.ToString();
    }
}
 

 

4. 자리수가 순차적으로 증가

 

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
 
public class Counter : MonoBehaviour
{
    TMP_Text textCount;
 
 
    void Start()
    {
        textCount = GameObject.Find("Canvas/CountText").GetComponent<TMP_Text>();
        StartCoroutine(numCount(987654321));
    }
 
 
 
    IEnumerator numCount(int nTargetNum)
    {
 
        string str = nTargetNum.ToString();
        string str2 = "";
        textCount.text = "";
 
        int nStrLength = str.Length;
 
        int[] nDigitNum = new int[nStrLength];
 
 
        nDigitNum[0] = nTargetNum / (int)Mathf.Pow(10, nStrLength - 1);
        
 
        for (int i = 0; i < nStrLength; i++)
        {
            nDigitNum[i] = nTargetNum % (int)Mathf.Pow(10, nStrLength-i) / (int)Mathf.Pow(10, nStrLength-i-1);
        }
 
        for (int i = 0; i < nStrLength; i++)
        {
            for (int j = 0; j < nDigitNum[i]; j++)
            {
                textCount.text = str2 + j.ToString();
                yield return new WaitForSeconds(0.05f);
            }
            str2 += str[i];
            textCount.text = "";
            for (int k = 0; k <= i; k++)
                textCount.text += str[k];
 
        }
        yield return null;
    }
 
 
}
