Syncvar isue, hook called but value not updated

pcthomart · 2017-09-21T20:27:04.000Z

Hello,
I make my first networking game, and I have an isue with the syncvar attribute, I Think I miss one think.

I have my variable here

[SyncVar(hook="OnObjectiveChange")]
private int m_nObjectiveId;

I modify it here (Only server modify the value)

public void SetObjective( int nObjective )
{
   if( isServer )
   {
      m_nObjectiveId = nObjective;
   }
}

On my client I go inside my hooked function

private void OnObjectiveChange( int nObjectivId )
{
   // Do stuff Change Hud
   Debug.Log( "Test Hook on client, new objective : " + nObjectiveId );
   ... 
}

I have on my client console

But on my element :

For informations, my element is a Registered Spawnable element, I use it to share gameplay information between my clients.

I could fix it by assigning my variable in the hooked function, but it’s not the good way, So if someone could explain me what wrong, it would be very nice.
Thanks!

UNet SyncVar with hook not syncing on clients

I've encountered an issue where my syncvar works fine without a hook but as soon as i give it a hook it stops syncing on all the clients but it still works for the host. The hook is still called when i try to change the variable but the variable it...

The answer would be that hook function works as some kind of override, so we have to manually assign the value on clients.

In this case, the documentation could be more explicit here :
