Resolved Weird Text Glitch/Bug?

I didn't know if to post this in the UI forum instead, but I decided to post it here because it might be something with the script. (First time ever posting a problem on a forum) I have an extremely weird bug that I cant find anywhere else where my text only updates for 1 frame, and then unity says that it can't find it anymore.
(This is code for when my weapon updates the text so it can display if you shot/reloaded and etc.)

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

using System;

using StarterAssets;

public class BlockShotAnims : MonoBehaviour

{

    public int currentAmmo = 1;

    public int reserveAmmo = 20;

    public int maxAmmo = 1;



    //doing the same script with TextMeshPro gave the exact same results.

    public Text cAmmo;

    public Text rAmmo;

    public Text mAmmo;



    void Update()

    {

        cAmmo.text = "" + currentAmmo;

        rAmmo.text = "" + reserveAmmo;

        mAmmo.text = "" + maxAmmo;

   }

}

        animan.SetBool("Inspecting", false);

        isInspecting = false;

        }

    }

}

Even though the proper GameObjects are put into the script, it still says it cant be found and that theres an error on the first line that an ammo.text pops up.
If someone could help a novice programmer out that would be greatly appreciated.

 

The error is in line 30 of that script. Check which object instance is affected by this, possibly one of the three c/r/mAmmo types. Then check when and where you assign them by a script, or destroy them, or destroy one of their parent objects.

This would also be a good situation to learn about the debugger, how to set breakpoints and step through code.

Also naming is very important because right now it‘ll be super easy to mistake mAmmo for rAmmo. These are labels, so call them currentAmmoLabel for instance.

 

Hey there, I used a work around where the ammo is counted in a separate script with the text as opposed to the animations and ammo in one. (Took note of the advise above concerning confusing names as well)

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

using TMPro;

public class BlocketLauncherAmmo : MonoBehaviour

{

    public static int currentAmmo = 0;

    public static int reserveAmmo = 15;

    public static int maxAmmo = 1;

    public TMP_Text currentAmmoText;

    public TMP_Text reserveAmmoText;

    public TMP_Text maxAmmoText;

//add a public void changeAmmo later so you don't waste memory updating the text when you don't need to

    void Update()

    {

        currentAmmoText.text = "" + currentAmmo;

        reserveAmmoText.text = "" + reserveAmmo;

        maxAmmoText.text = "" + maxAmmo;

    }

}

Then everything seemed to work perfectly with no errors!
Thanks a lot!
