How to loop through all player weapons?

Hell Phoenix · **Author**

Anyone know how I can loop through all the players weapons? Im looking to create a stock to strip all users weapons. I tried to follow what Team06 did in gungame...but there are things everywhere and it made my head spin....lol.

There two ways to do it. You can do it via a Prop Offset CAI_BaseNPC::m_hMyWeapons. You can look at devicenull first plugin. The weapon restriction plugin for usage.

The other way would be using sdktools GetPlayerWeaponSlot() would be mod dependent. You can see the sdktools.games.txt for which mod support GetPlayerWeaponSlot.

For CS:S the slots would be 0 for primary, 1 for secondary, 2 for knife, 3 for grenades, 4 for c4.

For grenades you have to loop threw the grenade slot to get all the clients grenades but you need to be very careful because if they have aleast 1 grenade. You can do an infinite loop if you do a while loop incorrectly.

Code:

Usage for getting all the grenades are wrong. Because GetPlayerWeaponSlot will always hit the first grenade in m_hMyWeapons. If he has hegrenade in the slot before flash, or smoke. It will always return hegrenade.

You have to walk the m_hMyWeapons to get the entity index. Then use CBaseCombatWeapon::GetSlot() to retrieve the slot in which that weapon hold. This is the only way you can retrieve all the grenades slots.

"kappa.games.txt"

Code:

/* Do not edit this file if you do not know what your doing. */
"Games"
{
	"#default"
	{
		"#supported"
		{
			"game"		"cstrike"
		}

		"Offsets"
		{

			"GetSlot"
			{
				"windows"		"280"
				"linux"			"281"
			}
		}
	}
}

Code:

#include <sourcemod>
#include <sdktools>

new m_hMyWeapons;
new Handle:GetSlot;
new Handle:GameConf

public OnPluginStart()
{
    m_hMyWeapons = FindSendPropOffs("CBasePlayer", "m_hMyWeapons");

    if(m_hMyWeapons == -1)
    {
        decl String:Error[128];
        FormatEx(Error, sizeof(Error), "FATAL ERROR m_hMyWeapons [%d]. Please contact the author.", m_hMyWeapons);
        SetFailState(Error);
    }

    GameConf = LoadGameConfigFile("kappa.games");
    CreateGetSlotHack();
}

DisplayPlayerGrenades(client)
{
    decl String:Class[64];
    for(new i = 0, ent; i < 128; i += 4)
    {
        ent = GetEntDataEnt(client, m_hMyWeapons + i);

        if(ent > 0 && HACK_GetSlot(ent) == 3)
        {
            GetEdictClassname(ent, Class, sizeof(Class));

            PrintToServer("Has [%s]", Class);
        }
    }
}

CreateGetSlotHack()
{
    StartPrepSDKCall(SDKCall_Entity);
    PrepSDKCall_SetFromConf(GameConf, SDKConf_Virtual, "GetSlot");
    PrepSDKCall_SetReturnInfo(SDKType_PlainOldData, SDKPass_Plain);
    GetSlot = EndPrepSDKCall();

    if(GetSlot == INVALID_HANDLE)
    {
        SetFailState("Virtual CBaseCombatWeapon::GetSlot Failed. Please contact the author.");
    }
}

HACK_GetSlot(entity)
{
    return SDKCall(GetSlot, entity);
}

Just use DisplayPlayerGrenades(client) on a player print out all the players grenades. This will walk the m_hMyWeapons for any weapon entity that is the grenade slot.

This is so you can see what grenades they have. Since GetPlayerWeaponSlot will return the first grenade in the m_hMyWeapons.

Code is untested but compiles.

I want to loop over the weapons in HL2MP.
But in the following code:

Code:

myweaponsoffset = FindSendPropOffs("CHL2MP_Player", "m_hMyWeapons");
new entit;

    decl String:Class[64];

    for(new i = 0; i < 128; i += 4)
    {
        entit = GetEntDataEnt(client, myweaponsoffset + i);
        }

entit always returns 0.

Am I doing something wrong or is this just HL2MP thing?

I am not quite sure, but instead of using "+= 4", try using "++"

Incrementing by 4 is essential.

That said, I can't see anything immediately wrong with that code snippet.

Nican · 09-25-2007 , 16:43 Re: How to loop through all player weapons?

Hm... How do you know all that stuff BAILOPAN?

The only difference I see now is that he is using CBasePlayer and you are using CHL2MP_Player

4-byte words. Have to increment by 4 to get to the start of the next word, instead of the middle of one.

Ah! I see now, I went to http://plugins.mfzb.de/offsets/CSTRIKE_Props.txt and found this:
