Host Health

Hi guys! I just want to say that I am a complete beginner and I'm trying to make a simple LAN game using UNet, I have a code for the Player Health with a syncvar health:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.UI;
6. using UnityEngine.Networking;
7.  
8. public class PlayerHealth : NetworkBehaviour
9. {
10.     public Text healthtxt;
11.     [SyncVar]public int health = 100;
12.  
13.     private void Update()
14.     {
15.         healthtxt.text = "HEALTH = " + health;
16.     }
17.     private void OnTriggerEnter(Collider other)
18.     {
19.        if(other.CompareTag("Sword"))
20.         {
21.             TakeDamage(other);
22.         }
23.     }
24.     void TakeDamage(Collider cmd_other)
25.     {
26.         health -= cmd_other.gameObject.GetComponent<SwordDamage>().damage;
27.     }
28.  
29. }
30.  

the thing is that the host is not updating his health value and neither the text, and I can't figure out why, some help would be very much appreciated

 

Add a [ServerCallback] tag to your OnTrigger function. This makes sure that you only modify the health on the server. It should then automatically sync to the client.
