Fill Experience Level Bar fast to slow

Questions & Answers
1

Hi, I made a level bar fill which goes from 0 to 1 for each level acquired. The value is a float. It increases with potions. I want the bar to go fast in the beginning and slower as it reaches it’s target level/Exp.

The problem is that if I increase the level from 1 to 20 using Time.deltaTime. It goes towards the targeted level but at the same speed. I tried different Mathf as well. Some do the trick but since the value is a float, towards the end of reaching the targeted level is becomes REALLLY slow. Which is something I don’t want.

Is there a way for me to control the speed depending on the experience bar reaching the targeted level? Thanks

Here’s my code using Mathf.MoveTowards :

ExperienceSlotUI[] expSlots;
LevelWindow levelWindow;
[SerializeField] public Button levelUpBtn;
public Animation anim;
[SerializeField] ParticleSystem particle;
[SerializeField] ParticleSystem particle2;
public int currentLevel;
public int level;
public float speed = 0.5f;
public float XpToAdd;//For ExpSlotUI;
private float target = 0;

    private void UpdateAddExperience()
    {
        
        if (levelWindow.expBarImage.value < target)
        {
            levelWindow.expBarImage.value = Mathf.MoveTowards(levelWindow.expBarImage.value, target, speed);
            
        }
        if (levelWindow.expBarImage.value >= 1)
        {
            IncreaseOriginalBar();
            ShowExperience(0);
        }
        if(levelWindow.expBarImage.value >= target)
        {
            isAnimating = false;
            //Restart XpToAdd
            XpToAdd = 0;
            //Faire disparraitre un mask transparent
            Destroy(mask);
            //activate btn
            EnableExpBtn();
            //Deactivate particle effect
            particle.Stop();
            particle2.Stop();

        }
    }

   private void LevelUP()
   {
        levelWindow.expBar2Image.gameObject.SetActive(false);
        levelWindow.expBarImage.gameObject.SetActive(true);

        ShowExperience(XpToAdd);
        //Faire apparaitre un mask transparent
        SetupMask();
        //Reset expUsed
        ResetExpUsed();
       
        
        
        //Add to baseStats
        levelWindow.baseStats.IncreaseXP2((int)(XpToAdd));

        //Deactivate levelup btn
        levelUpBtn.enabled = false;
    }

    private void ShowExperience(float expToAdd)
    {
        target = ((levelWindow.baseStats.GetPoints() + expToAdd) / levelWindow.baseStats.GetRequiredXPForLevel(currentLevel));
        isAnimating = true;
        
    }:

You can use Time.deltaTime. It is mostly used to leave movements, positions, rotations, scales in a smooth transition time. However, you can decrease it by dividing it, in the same way that you use * to multiply and increase the speed, you can use / to decrease the speed. Example:

Time.deltaTime / 5
