Fill Progress Bar Over Time

Anyone have an example of how to fill a progress bar over time? Building a crafting system and I want to wait until 1.5 seconds has elapsed and fill a progress bar.

 

You could use a Coroutine: something like that

Code (CSharp):

1. IEnumerator(ProgressbarRef, duration)
2. {
3.    float time = 0.0f;
4.    while(time < duration)
5.    {
6.       ProgressbarRef.progress = time / Mathf.Max(duration, SmallEpsilon);
7.       time += Time.deltaTime;
8.       yield return new WaitEndOfFrame();
9.    }
10. }

Now whenever you need to start a loading process on a progressbar object you call: StartCoroutine(progressbar, 1.5f)

I did not test this, but it might give you a starting point.

Cheers,
Tobi

 

SmallEpsilon? this the amount you increase the progress bar value by?

 

It's a small value to handle the case where duration is 0. If duration was ever 0, then you'd get a DivideByZero exception.

 

This is awesome, thanks for the question @mholmes and the answer @Tobs and the clarification @kru
What a fantastic community

 

Here is what I created based on help:

Code (CSharp):

1. IEnumerator Craft_Item(int duration, int TotalAmount)
2.     {
3.         //Base Crafting System
4.         Core_Functions core = new Core_Functions();
5.         //Base Crafting Item Return
6.         Base_Crafting_Item_Return base_return = new Base_Crafting_Item_Return();      
7.  
8.         //For Each Item To Craft
9.         for (int i = 0; i < TotalAmount; i++)
10.         {          
11.             bool hasingrediants = _Crafting_Functions.Ingrediant_Check();
12.  
13.             //Ingrediants Check
14.             if (hasingrediants)
15.             {
16.                 //Display Progress In Text
17.                 Crafting_Data._CurrentAmount = i;
18.                 _CraftAmount.text = (Crafting_Data._CurrentAmount + 1).ToString() + "/" + Crafting_Data._TotalAmount.ToString();
19.                 base_return = core.Craft_Item(Crafting_Data._itemname, Crafting_Data._Player_Skill_Level);
20.  
21.                 //Crafted Item Successfully
22.                 if (base_return.Success)
23.                 {
24.                     FindObjectOfType<AudioManager>().Play("Craft_Rune_Success");
25.                 }
26.                 //Failed To Craft Item
27.                 else
28.                 {
29.                     FindObjectOfType<AudioManager>().Play("Craft_Rune_Failed");
30.                 }
31.  
32.                 //Progress Bar Display
33.                 while (_Crafting_Progress < duration)
34.                 {
35.                     _pbCrafting.value = _Crafting_Progress;
36.                     _Crafting_Progress += 0.1f;
37.                     yield return new WaitForSecondsRealtime(0.1f);
38.                 }
39.  
40.                 //Consume Ingrediants
41.                 Consume_Ingrediants();
42.                 //Craft Item
43.                 if (base_return.Success) { _Crafting_Functions.Update_Craft_Inventory(Crafting_Data._itemname, base_return.Bonus); }
44.                 //Reset Progress
45.                 _Crafting_Progress = 0.00f;
46.             }
47.             else
48.             {
49.                 _CraftAmount.text = "Missing Required Ingredients";
50.                 FindObjectOfType<AudioManager>().Play("Crafting_Error");
51.                 _pbCrafting.value = 0;
52.                 _Crafting_Progress = 0;
53.                 _pbCrafting.gameObject.SetActive(false);
54.                 yield return new WaitForSecondsRealtime(3.5f);
55.                 break;
56.             }
57.         }
58.  
59.         //Reset Display
60.         Crafting_Data._IsCrafting = false;
61.         _pbCrafting.value = 0;
62.         _Crafting_Progress = 0;
63.         _CraftAmount.text = "Amount";
64.         _pbCrafting.gameObject.SetActive(false);
65.         _btnCraftItem.enabled = true;
66.         _CraftAmount.readOnly = false;
67.     }

This is a nearly complete crafting system.
