Stamina doesn't decrease

Hello,

I was wondering if someone could help me with a script problem. My stamina doesn't work whenever I'm running, the stamina is supposed to decrease.
My PlayerStats:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5.  
6. public class PlayerStats : MonoBehaviour {
7.  
8.     [SerializeField]
9.     private Image health_Stats, stamina_Stats;
10.  
11.     public void Display_HealthStats(float healthValue) {
12.  
13.         healthValue /= 100f;
14.  
15.         health_Stats.fillAmount = healthValue;
16.  
17.     }
18.  
19.     public void Display_StaminaStats(float staminaValue) {
20.  
21.         staminaValue /= 100f;
22.  
23.         stamina_Stats.fillAmount = staminaValue;
24.  
25.     }
26.  
27.  
28. }

My HealthScript:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;

I see you are making a call to Display_HealthStats when you take damage, which is great, but I don't see you ever calling Display_StaminaStats. But then, the second script you show is a health script, so I'm not sure that I'd expect changes to Stamina to be made from that script.

Where do you call Display_StaminaStats from?

 

Hi,
If I'm correct the Display_Stats is called in my sprintandcrouch script and the stamina is supposed to decrease when i hold Left shift and walk/run i think. The thing is it doesn't work. It might be tied to my other problem: pressing or holding buttons to shoot or run etc doesnt work.

The sprint code is:

The code should work. Are you sure stamina_Stats Image is set to Filled type?

 

I would suggest adding some Debug.Log statements through your sprint code and see if it's executing the parts you think it should. Then add another to your Display_StaminaStat method and see if that is executing. If your debug messages print out, then at least you know the code is running. But wouldn't hurt to check out what @Elango mentioned first as that would be a quick check.
