SyncVar not syncing properly

Questions & Answers
1

I have a player prefab with 1 field - energy, that is decreasing in random time (using Coroutines). When I run the game, all is working correctly, but when I add [SyncVar] to it, it starts to “jump”. Then I used hooks, and this is what i recieved:

The code is:

public class CatData : NetworkBehaviour
{
    [SyncVar(hook = "OnEnergyChanged")]
    private int energy;
    public Transform energyBar;
    void Start()
    {
        energy = 100;
        StartCoroutine(Energy());
    }
    void Update()
    {
        energyBar.localScale = new Vector3((float)energy / 100 * 2.39f, energyBar.localScale.y, energyBar.localScale.z);
        if (energy <= 0)
        {
            energy = 0;
        }
        if (energy > 100)
        {
            energy = 100;
        }
    }
    void OnEnergyChanged(int value)
    {
        energy = value;
        Debug.Log("Energy changed: " + energy);
    }
    IEnumerator Energy()
    {
        while (energy > 0)
        {
            yield return new WaitForSeconds(Random.Range(2, 5));
            DecreaseEnergy(2, 10);
        }
    }
    public void DecreaseEnergy(int min, int max)
    {
        energy -= Random.Range(min, max);
    }
}

I’d like to know how to fix energy to work and sync properly

Is it possible that its doing the calculations on the server and the client and giving you the Debug for both?

If you look at the SyncHook documentation,
if (isServer){
return;
}

not sure if that helps. I haven’t used hooks before.
