Hello,

I am currently enjoying my new plugin coding.
Being only one Apprentice I still have some trouble focusing.
I am looking how I can force a player to control: cl_crossairalpha 0
I wish that when he joined, the viewfinder are off.

I am Belgian and I use a translator to write this post.

Thank you.

Kriax.

You can user

PHP Code:

ClientCommand() 


to change the variable.

[Kriax]

ClientCommand(client, "cl_crosshairalpha 0");

If I put it in ONPLAYERSPAWN her go?

Hello Kriax,

thankfully the server can't change client cvars.
What you can do is to get the value of the client's cvar with QueryClientConVar() periodically asynchronously and kick the client if he didn't change the cvar.

Can you ? or is it just a wild guess ?

I highly doubt ClientCommand can change a client cvar.

[Kriax]

Aye an other commande ?

try

PHP Code:

#define HIDEHUD_CROSSHAIR 256
...
new hud = GetEntProp(client, Prop_Send, "m_iHideHUD");
hud |= HIDEHUD_CROSSHAIR;
SetEntProp(client, Prop_Send, "m_iHideHUD", hud);

public OnPluginStart()
{
      HookEvent("player_spawn", Event_player_spawn)
}
 
public Action:Event_player_spawn(Handle:event, const String:name[], bool:dontBroadcast)
{
 client = GetClientOfUserId(GetEventInt(event, "userid"))
QueryClientConVar(client, "cl_crossairalpha 0", ConVarQueryFinished:ClientConVar, client)
 
 return Plugin_Continue
 }
 
 public ClientConVar(QueryCookie:cookie, client, ConVarQueryResult:result, const String:cvarName[], const String:cvarValue[])
 {
       GetClientName(client, name, 64)
       PrintToServer("%s CVar %s = %s", name, cvarName, cvarValue)
 }

Is it fair if I put this?

I would try what blodia said.
And it's most likey named "cl_crosshairalpha", not "cl_crossairalpha":

ClientCommand doesn't work for this, FakeClientCommand does.

PHP Code:

//Fix if user changes the value back.
new Handle:g_hCheck

public OnPluginStart()
{
    HookEvent("player_spawn", Spawn)

    //Link Cvar
    g_hCheck = FindConVar("cl_crosshair_alpha");

    if (g_hCheck != INVALID_HANDLE)
    {
        HookConVarChange(g_hCheck, OnValueChange);
    }
}

public Action:Spawn(Handle:event, const String:name[], bool:dontBroadcast)
{
    //Get Spawned Player's Info.
    client = GetClientOfUserId(GetEventInt(event, "userid"))

    //Make the player send the command.
    ClientCommand(client, "cl_crosshair_alpha 0");
}

public OnValueChange(Handle:cvar, const String:oldVal[], const String:newVal[])
{
    //If Value is higher than 0, switch it to 0.
    if (StringToInt(newVal) > 0)
    {
        SetConVarInt(cvar, 0);
    }
}
