I have done this to hook the players picking items when theres a knife round, everything is working fine except it let players get droped items, but since i did a late load of the plugin, i think thats why it's not working, because i did the hook OnClientPutInServer() that is why the plugin is not working well, but since i ussually load and unload plugins every x time, i'll like to get a way to handle it, theres the code:

PHP Code:

public OnClientPutInServer(client) {
    SDKHook(client, SDKHook_WeaponCanUse, BlockPickup);
}

public OnClientDisconnect(client) {
    SDKUnhook(client, SDKHook_WeaponCanUse, BlockPickup);
} 


and

PHP Code:

public Action:BlockPickup(client, weapon){
    if (g_enabled && g_isKnifeRound) {
        PrintHintText(client, "%t","Knife round is enabled");
        return Plugin_Handled;
    }
    return Plugin_Continue;
} 


How i can manage to hook it when i late load the plugin?

You can use AskPluginLoad2

PHP Code:

new bool:g_bLateLoaded = false;

public APLRes:AskPluginLoad2(Handle:myself, bool:late, String:error[], err_max)
{
  g_bLateLoaded = late;
  return APLRes_Success;
}

public OnPluginStart()
{
  //...

  if (g_bLateLoaded)
  {
    for (new i = 1; i <= MaxClients; i++)
    {
      if (IsClientInGame(i)) //Add other checks, e.g. IsClientSourceTV, if needed
      {
        SDKHook(i, SDKHook_WeaponCanUse, BlockPickup);
      }
    }
  }
}

Thanks, it did the job well, but if I unload the plugin, should I close the hooks? An if yes, what's the best way to do it?

You dont need to close sdhooks hooks, sdkhooks do it for you when entity is destroyed/player disconnected.

[psychonic]

Any entities hooked with SDKHooks in a plugin will be automatically unhooked when the plugin unloads.

Then This code isn't needed?

PHP Code:

public OnClientDisconnect(client) {
    SDKUnhook(client, SDKHook_WeaponCanUse, BlockPickup);
}

That is correct.

[Chdata]

That's correct for a different reason. You don't need to unhook when a client disconnects from the server.

I'm not sure exactly why though. It's either because you can't hook something twice (which I doubt, you probably actually can and have double repeating code), or because client entities don't actually get "killed" or "removed" - at least that's my theory as I don't know - that when someone connects his control is exerted on an existing player entity that's being unused.


Or maybe SM does unhook clients on disconnect, who knows.

I have seen many plugins hook stuff on player spawn. Now I'm wondering how long these hooks stay active. And if hooktype + entindex + callback-address is unique so that it wouldn't be hooked or called multiple times.
