Hello, I'm new in SourcePawn scripting and I request help to make a script :
I want to set a new FOV for the players.
I tried to use CBasePlayer::SetFOV from the http://forums.alliedmods.net/showthread.php?t=55565
This is my scripts who don't work

PHP Code:

public Plugin:myinfo = 
{
    name = "FOV Changer",
    author = "HRG Team - Tournevis_man and Pinguinman",
    description = "Set the FOV to a player",
    version = "1.0.0",
    url = "http://www.sourcemod.net/"
};

#include <sourcemod>
#include <sdktools>
#undef REQUIRE_PLUGIN
#include <adminmenu>
#include <sigoffset>
new Handle:g_cvar = INVALID_HANDLE;

public OnPluginStart()
{
    g_cvar = FindConVar ("fov_desired")

    RegAdminCmd("sm_fov", SetFOV, ADMFLAG_CUSTOM1, "sm_fov <FOV> Sets the FOV of given value. Default: 90");
}
    

public CBasePlayer::SetFOV(clients, args)
{
    if (args < 1)
    {        ReplyToCommand(client, "[SM] Usage: sm_fov <fov>");
        return Plugin_Handled;
    }
    decl String:arg[64];
    GetCmdArg(1, arg, sizeof(arg));

    SetConVarInt(g_cvar, StringToInt(arg));
    PrintToChatAll("[SM] FOV set to: %s", arg);                    
    LogMessage("Chat: %L FOV set to: %s", client, arg);
    return Plugin_Handled;
} 


Thanks for help

Ok, CBasePlayer::SetFov is a signature. Signature scanning is handled in sdktools.inc.

But rather than explain all that I'll show you another way to change FOV that is a lot easier.

new offsFOV;

public OnPluginStart()
{
    offsFOV = FindSendPropInfo("CBasePlayer", "m_iDefaultFOV");
    if (offsFOV == -1)
    {
        SetFailState("Couldn't find \"m_iDefaultFOV\"!");
    }
    RegAdminCmd("sm_fov", SetFOV, ADMFLAG_CUSTOM1, "sm_fov <#userid|name> <FOV> Sets the FOV of given value. Default: 90");
}

public Action:SetFOV(client, args)
{
    if (argc < 2)
    {
        ReplyToCommand(client, " sm_fov <#userid|name> <FOV> Sets the FOV of given value. Default: 90");
    
        return Plugin_Handled;
    }

    decl String:arg1[32];
    decl String:arg2[8];
    
    GetCmdArg(1, arg1, sizeof(arg1));
    GetCmdArg(2, arg2, sizeof(arg2));
    
    new fov = StringToInt(arg2);
    
    decl String:target_name[MAX_TARGET_LENGTH];
    new targets[MAXPLAYERS];
    new bool:tn_is_ml;
    
    new tcount = ProcessTargetString(arg1, client, targets, MAXPLAYERS, COMMAND_FILTER_ALIVE, target_name, sizeof(target_name), tn_is_ml);
    if (tcount <= 0)
    {
        ReplyToTargetError(client, tcount);
        return Plugin_Handled;
    }
    
    for (new x = 0; x < tcount; x++)
    {
        SetEntData(targets[x], offsFOV, fov, 1);
    }
    
    if (tn_is_ml)
    {
        ShowActivity2(client, "[SM] ", "%t", "Toggled dizziness on target", target_name);
    }
    else
    {
        ShowActivity2(client, "[SM] ", "%t", "Toggled dizziness on target", "_s", target_name);
    }

    return Plugin_Handled;
}

public Action:SetFOV is referred to as a "cmd callback." It means that I hooked the function in OnPluginStart (RegAdminCmd) and now this function is called whenever an admin uses the sm_fov command.

offsFOV is a global variable used to store the m_iDefaultFOV offset. In OnPluginLoad I used FindSendPropInfo to find the offset. (http://bailopan.net/table_dump.txt)
The FindSendPropInfo function is nested, which means that all you need is the classname and property. If you look at that page you will find

CBasePlayer: Sub-Class Table (1 Deep): DT_BasePlayer Sub-Class Table (2 Deep): DT_BaseCombatCharacter Sub-Class Table (3 Deep): DT_BaseFlex Sub-Class Table (4 Deep): DT_BaseAnimatingOverlay Sub-Class Table (5 Deep): DT_BaseAnimating Sub-Class Table (6 Deep): DT_BaseEntity Sub-Class Table (7 Deep): DT_AnimTimeMustBeFirst -Member: m_flAnimTime (offset 40) -Member: AnimTimeMustBeFirst (offset 0) -Member: m_flSimulationTime (offset 44) ...

So FindSendPropInfo, being nested, will check through alll those sub-classes under CBasePlayer looking for the property you gave it. It will return -1 if it doesn't exist for that game.

Hope that helped

Thanks a lot for your help
