Lerp animation on health bar

Hello, im stuck since this morning(in china) im trying to make my Health and shield bar Sliders move when there is damages. but i want to make the slider value moving smoothly with a lerp, but i cant find the proper way to do this, i feel im very close to, could someone check my script please?

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class HealthBar : MonoBehaviour {
5.  
6.     public int CurHealth;
7.     public int Maxhealth;
8.     public int CurShield;
9.     public int Maxshield;
10.     GameObject CombatPanel;
11.    
12.     public float test;
13.     int OldCurHealth;
14.     int OldCurShield;
15.    
16.     //Bar Floats
17.     public float HealthFloat;
18.     public float ShieldFloat;
19.     public float EaseTime;
20.    
21.     public bool EaseBool=false;
22.    
23.    
24.     public void GetStats()
25.     {
26.     Maxhealth = CombatPanel.GetComponent<CombatManager>().MaxHealth;
27.     Maxshield = CombatPanel.GetComponent<CombatManager>().ShieldMax;
28.     CurHealth = CombatPanel.GetComponent<CombatManager>().Health;
29.     CurShield = CombatPanel.GetComponent<CombatManager>().ShieldValue;
30.  
31.    
32.     }
33.     public void GetOldStats()
34.     {
35.         OldCurHealth = CombatPanel.GetComponent<CombatManager>().Health;
36.         OldCurShield = CombatPanel.GetComponent<CombatManager>().ShieldValue;
37.     }
38.  
39.     void Start()
40.     {
41.     CombatPanel =GameObject.FindGameObjectWithTag("CombatPanel");
42.     GetStats ();
43.         GetOldStats();
44.     }
45.    
46.    
47.     public void HealthChange()
48.     {
49.        
50.         GetStats ();
51.    
52.        
53.         //set Sliders (animate)
54.         StartCoroutine("EaseBAR");
55.        
56.         GameObject.Find ("SliderSB").GetComponent<UISlider>().sliderValue = ShieldFloat;
57.         GameObject.Find ("SliderHB").GetComponent<UISlider>().sliderValue = HealthFloat;
58.         //get old values at the end to compare
59.         GetOldStats ();
60.     }
61.    
62.     // Update is called once per frame
63.     void Update ()
64.     {      
65.         HealthChange ();
66.        
67.         if(EaseBool)
68.         {
69.             EaseTime=Time.deltaTime;
70.             if(EaseTime>1)
71.             {
72.                 //stopeasing
73.             }
74.         }
75.        
76.     }
77.    
78.     void Curveanim()
79.     {
80.         //shield
81.         ShieldFloat = ((float)CurShield)/((float)Maxshield);
82.        
83.         //health
84.         HealthFloat = ((float)CurHealth)/((float)Maxhealth);
85.        
86.         //ease
87.         test = Mathf.Lerp(1.0f,3.0f, 6.0f);// bug here: test stay to 0
88.         GameObject.Find ("SliderSB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurShield),ShieldFloat, EaseTime);
89.         GameObject.Find ("SliderHB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurHealth),HealthFloat, EaseTime);
90.     }
91.    
92.    
93.     IEnumerator EaseBAR()
94.     {
95.         EaseTime = 0;
96.         //shield
97.         ShieldFloat = ((float)CurShield)/((float)Maxshield);
98.        
99.         //health
100.         HealthFloat = ((float)CurHealth)/((float)Maxhealth);
101.        
102.         //ease
103.         test = Mathf.Lerp(1.0f,3.0f, Mathf.SmoothStep (0.0f,1.0f,EaseTime));// bug here: test stay to 0
104.         GameObject.Find ("SliderSB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurShield),ShieldFloat, EaseTime);
105.         GameObject.Find ("SliderHB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurHealth),HealthFloat, EaseTime);
106.    
107.         yield return new WaitForSeconds(EaseTime);
108.     }
109. }
110.  

im not doing code since longtime so im pretty bad at this, but i dont like to stuck on my problems:-?

 

It looks like in the code bellow EaseTime is always 0. Try to change it to something more, for example 0.1f

Code (csharp):

1.  
2.     IEnumerator EaseBAR()
3.     {
4.         EaseTime = 0;
5.  
6.         //shield
7.         ShieldFloat = ((float)CurShield)/((float)Maxshield);
8.  
9.         //health
10.         HealthFloat = ((float)CurHealth)/((float)Maxhealth);
11.  
12.         //ease
13.         test = Mathf.Lerp(1.0f,3.0f, Mathf.SmoothStep (0.0f,1.0f,EaseTime));// bug here: test stay to 0
14.         GameObject.Find ("SliderSB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurShield),ShieldFloat, EaseTime);
15.         GameObject.Find ("SliderHB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurHealth),HealthFloat, EaseTime);
16.  
17.         yield return new WaitForSeconds(EaseTime);
18.     }
19.  

 

i changed the value but it doesnt work too, there is something that dont ease my float, i cant find where

 

Ok, the simpliest test. It should works well:

Code (csharp):

1.  
2.         IEnumerator EaseBAR()
3.         {
4.             EaseTime = 0.1F;
5.      
6.             //ease
7.             test = Mathf.Lerp([B]test[/B], 3.0f, EaseTime);// bug here: test stay to 0
8.  
9.             yield return new WaitForSeconds(EaseTime);
10.         }
11.  

Mathf.Lerp have to recieve 3 variables: initialValue, targetValue and currentPosition (progress).
You can use them in 2 ways:
1)
test = Mathf.Lerp(test, 3.0f, EaseTime);
in this case EaseTime can be unchangable variable, because initialValue always increase (it is "test" variable)

2)
test = Mathf.Lerp(0.0f, 3.0f, EaseTime);
in this case initialValue and targetValue is constant, and EaseTime must increase from 0.0f to 1.0f (EaseTime can not be unchangable).

 

thank you for the answer, the first case worked but i cant use it on my case because:

my function work like this each time receive damages, I move my float from OldCurHealth to HealthFloat during Easetime seconds

maybe its an other function ? i tried lerp and step but cant move it the way i want

for exemple something like

Code (csharp):

1. myfloat = Easefunction(0,1,5 )//this will move my float from 0 to 1 in 5 seconds

Code (csharp):

1.     IEnumerator EaseBAR()
2.     {
3.             //health
4.             HealthFloat = ((float)CurHealth)/((float)Maxhealth);
5.        
6.             //ease
7.             GameObject.Find ("SliderHB").GetComponent<UISlider>().sliderValue = Mathf.Lerp(((float)OldCurHealth),HealthFloat, EaseTime);
8. //need to move the float "SliderValue" from "OCurHealth" to "HealthFloat" in xxseconds(Easetime)
9.             yield return new WaitForSeconds(EaseTime);
10.     }

 

I know it's old, but I'm just adding this here for everyone's reference. The couroutine is written wrong.

It should be StartCoroutine(EaseBAR()); not StartCoroutine("EaseBAR");

 

In respect of starting the Coroutine both are identical, the only difference is in the available method you'd use to stop them.

This seems to have been a bit of a pointless necro.
