I should point out now that I am developing for a Linux Team Fortress 2 server.

So I have just discovered the joys of offsets. For my latest plugin mock-up I would like to return the names of weapons as they appear in the kill cam as these weapons names are names that people recognise rather than being tf_weapon_bat_wood etc. I had a look in CBaseCombatWeapon and found a few functions that looked interesting however I have no idea how to use them. My problem being is how do I know what parameters to add when I am preparing the SDK call and what I should expect to be returned.

I already have a few SDK calls such as this:

PHP Code:

    StartPrepSDKCall(SDKCall_Player);
    PrepSDKCall_SetFromConf(gameConf, SDKConf_Virtual, "GiveNamedItem");
    PrepSDKCall_AddParameter(SDKType_String, SDKPass_Pointer);
    PrepSDKCall_AddParameter(SDKType_PlainOldData, SDKPass_Plain);
    PrepSDKCall_AddParameter(SDKType_PlainOldData, SDKPass_Plain);
    PrepSDKCall_SetReturnInfo(SDKType_CBaseEntity, SDKPass_Plain);
    giveNamedItem = EndPrepSDKCall(); 


MikeJS coded the above block and it works 100%. What I would like to know is how would I find out these parameters and returns for myself for something like this:

PHP Code:

    StartPrepSDKCall(SDKCall_Player);
    PrepSDKCall_SetFromConf(gameConf, SDKConf_Virtual, "GetDeathNoticeName");
/*  Some Parameters
    and returns in here */
    getDeathNoticeName = EndPrepSDKCall(); 


Thanks in advance for your time and advice.

Ok I am getting desparate now, why wont something like this return a string:

PHP Code:

new Handle:getPrintName; 


PHP Code:

    gameConf = LoadGameConfigFile("test.games");

    StartPrepSDKCall(SDKCall_Entity);
    PrepSDKCall_SetFromConf(gameConf, SDKConf_Virtual, "GetPrintName");
    PrepSDKCall_SetReturnInfo(SDKType_String, SDKPass_Pointer);
    PrepSDKCall_SetReturnInfo(SDKType_PlainOldData, SDKPass_Plain);
    getPrintName= EndPrepSDKCall(); 


PHP Code:

    new String:testStr[64];
    SDKCall(getPrintName, ent, testStr, 64);            
    PrintToChat(client, "SDK Call: %s", testStr); 


The offsets should be correct but here they are anyway:

"Games"
{
    "tf"
    {
        "Offsets"
        {
            "GetPrintName"
            {
                "windows"    "307"
                "linux"      "308"
            }
        }
    }
}

Any ideas what I am doing wrong? In-game there are no errors just a string in my chat log saying "SDK Call: "

You've set return info twice.

Remove

PrepSDKCall_SetReturnInfo(SDKType_PlainOldDat a, SDKPass_Plain);

[Wazz]

So you can only use ReturnInfo once per prep? I didn't have much to go on so I guessed there would be 2 returns, one for the string and one for the size of the string. Anyway, thanks for the info

Just a quick edit: Thanks again pRED, that was what I needed to know to get me going. I have actually managed to construct a plugin that blocks selected unlockable weapons for TF2

C++ only supports a single return value for functions. Any other return data must be returned by reference through params (note the copyback flags).

Strings returned are NULL ('\0') terminated to determine the length.
