Detecting when shield is hit (not just aiming at it)
 
i searched the forum and found only ways to detect when user is aiming at the shield but not hitting it with the bullet, i want to make an action only when shield is hit not when you just look at it, maybe someone found a way ?

i tried get_tr2( tr, TR_iHitgroup ) in TraceAttack pre and post but traceattack isn't even called for shield

Re: Detecting when shield is hit
 
you could rebuild the traceline the engine sends and check yourself whether it hits the shield or not, use FM_EmitSound (bad method) or some better way which hopefully exists ^^

IIRC the hitgroup of shield is 8.

EDIT:As i knew -> http://forums.alliedmods.net/showpos...57&postcount=5

for 8th hitgroup TraceAttack isn't called and traceline hooks aiming not shooting (as far as i know)

i haven't done anything like that yet, could you help me little further?

You can simply modulate TraceLine to detect attack. Just hook CmdStart forward, check Buttons&IN_ATTACK then do a traceline ? There are some other ways too...

Re: Detecting when shield is hit (not just aiming at it)
 
,Owyn. yet, i wont give you the code but i will tell you how you can find out how to do what you want (learn-effect):
- download the hlsdk
- search in mp5.dll for the function which is called when the weapon is fired and find the function inside which checks for a hit
- the function is located in combat.cpp
- understand its code, try to rebuild it in pawn and add your shieldhit detection

if its really that hard for you (at least try it) i may help you as soon as i got more motivation + time ;D

@Alka
i guess you know my knife-distance plugin and how it detects the attack type (tracehandle value), should be possible here too :) also, there is already a tutorial of VEN about this (Owyn search for it in the code snippets section, might be helpful) which does not check pev_buttons or uses cmdstart in general ^^

Yea, but my idea is a simple way (: i said

Re: Detecting when shield is hit (not just aiming at it)
 
There isn't a clean way to do this since when you hit a shield a traceattack doesn't occur and the shield doesn't even exist as an entity. This is the best way I found:

PHP Code:

#include <amxmodx>
#include <hamsandwich>
#include <fakemeta>
#include <xs>

#define PLUGIN    "New Plugin"
#define AUTHOR    "Unknown"
#define VERSION    "1.0"

const m_iClip = 51
const m_iClip_linuxoffset = 4

new Weapons[] = 
{
    CSW_P228,
    CSW_SCOUT,
    CSW_XM1014,
    CSW_C4,
    CSW_MAC10,
    CSW_AUG,
    CSW_ELITE,
    CSW_FIVESEVEN,
    CSW_UMP45,
    CSW_SG550,
    CSW_GALI,
    CSW_GALIL,
    CSW_FAMAS,
    CSW_USP,
    CSW_GLOCK18,
    CSW_AWP,
    CSW_MP5NAVY,
    CSW_M249,
    CSW_M3,
    CSW_M4A1,
    CSW_TMP,
    CSW_G3SG1,
    CSW_DEAGLE,
    CSW_SG552,
    CSW_AK47,
    CSW_KNIFE,
    CSW_P90,
}

public plugin_init()
{
    register_plugin(PLUGIN, VERSION, AUTHOR)
    
    new weaponName[24];
    for(new i=0;i<sizeof Weapons;i++)
    {
        get_weaponname(Weapons[i],weaponName,charsmax(weaponName));
        RegisterHam(Ham_Weapon_PrimaryAttack,weaponName,"attack")
    }
}

public attack(weaponID)
{
    if(get_pdata_int(weaponID,m_iClip,m_iClip_linuxoffset))
    {
        static Float:start[3], Float:dest[3] , Float:viewOffset[3], Float:path[3]
        
        new id = pev(weaponID,pev_owner)
        
        pev(id,pev_origin,start);
        pev(id,pev_view_ofs,viewOffset);
        xs_vec_add(start,viewOffset,start);

        pev(id,pev_v_angle,path);
        engfunc(EngFunc_MakeVectors,path);
        global_get(glb_v_forward,path);

        xs_vec_mul_scalar(path,9999.0,dest);
        xs_vec_add(start,dest,dest);
            
        engfunc(EngFunc_TraceLine,start,dest,0,id,0);
        
        if(get_tr2(0,TR_iHitgroup) == 8)
        {
            client_print(0,print_chat,"Hit Shield")
        }
    }
} 
You have to modify it to handle the knife attack right because, as it is, as long you are aiming at a shield (no matter how far from it) and you use the weapon primary attack, it reports a shield hit. (Or ask Schweinsteiger* to do it for you)

Re: Detecting when shield is hit (not just aiming at it)
 
you get same result just checking pev button IN_ATTACK in traceline, atm i think hooking shield-hit sound with fakemeta is a nice way

You get the same results but is some hundred times more expensive.

And thinking again, no you don't. You can be pressing IN_ATTACK without attacking.
