Make AWP 100% accurate
 
Hello there.

I've been wondering, if there was a way to make the AWP 100% accurate. Or do I have to do the hit checking myself?

EDIT: Oh. Could this please be moved to Scripting Help?

Check for the weapon.

Re: Make AWP 100% accurate
 
Thx. I already found another solution.

PHP Code:
public fw_Weapon_PrimaryAttack_Pre(weapon_ent)
{
    playerEntityId = get_pdata_cbase(weapon_ent, OFFSET_WEAPON_OWNER, OFFSET_LINUX_WEAPONS);
    
    fov = pev(playerEntityId,pev_fov)
    set_pev(playerEntityId,pev_fov,10)
    
    if(!pev_valid(playerEntityId) || cs_get_weapon_ammo(weapon_ent) < 1)
        return HAM_IGNORED;
    
    oldFlags = entity_get_int(playerEntityId, EV_INT_flags);
    entity_get_vector(playerEntityId, EV_VEC_velocity, oldVelocity);
        
    // Make the attack function think we're on the ground
    entity_set_int(playerEntityId, EV_INT_flags, oldFlags | FL_ONGROUND | FL_DUCKING);
    
    // If we're already in the air, make the attack function think we're not moving.
    // Not sure if this needs to be here.
    if (oldFlags & FL_ONGROUND) {
            entity_set_vector(playerEntityId, EV_VEC_velocity, zeroVector);
    }
    
    
    
    return HAM_IGNORED;
}

public fw_Weapon_PrimaryAttack_Post(weapon_ent)
{
    set_pev(playerEntityId,pev_fov,fov)
    
    entity_set_vector(weapon_ent, EV_VEC_punchangle, Float:{0.0,0.0,0.0});
    
    new id = get_pdata_cbase(weapon_ent, OFFSET_WEAPON_OWNER, OFFSET_LINUX_WEAPONS);
    
    entity_set_int(id, EV_INT_flags, oldFlags);
    entity_set_vector(id, EV_VEC_velocity, oldVelocity);
    
    return HAM_HANDLED;
} 
Parts are from the cs1.3 plugin that's around. And this should be more efficient due to less copying than the iaimgood one. BUT I don't know if it works for other weapons as well.

At least I think it is like that :P

Re: Make AWP 100% accurate
 
ask arkshine to teach u how to use orpheu, just hack three float value, in CAwp:: PrimaryAttack()
Code:
void CAWP::PrimaryAttack()
{
    if ( !FBitSet( m_pPlayer->pev->flags, FL_ONGROUND ) )
    {
        AWPFire( 0.85, 1.45 );
    }
    else if ( m_pPlayer->pev->velocity.Length2D() > 140 )
    {
        AWPFire( 0.25, 1.45 );
    }
    else if ( m_pPlayer->pev->velocity.Length2D() > 10 )
    {
        AWPFire( 0.10, 1.45 );
    }
    else if ( FBitSet( m_pPlayer->pev->flags, FL_DUCKING ) )
    {
        AWPFire( 0.0, 1.45 );
    }
    else
    {
        AWPFire( 0.001, 1.45 );
    }
}
code from arkshine's sdk
you see that the first parameter in AWPFire ? that's the spread rate, change all of them to 0.0

Re: Make AWP 100% accurate
 
Already thought of that, maybe I'll do that today. Hmmm. But how can I do that with Orpheu. Somethin about orpheu_memory?

But one thing:

PHP Code:
if ( m_pPlayer->pev->fov == 90 )
    {
        flSpread += 0.08;
    } 
I will still have to change that one. In my opinion the best thing would be to hook for AWPFire, but I didn't find the offset. Could it be that AWPFire is no virtualFunction?

Re: Make AWP 100% accurate
 
Hmmm. One problem there:

What is the signature of AWPFire? Can't really find it.

Re: Make AWP 100% accurate
 
Forget about retrieving a decent signature for such function because the content is almost the same for such weapons and it's impossible to get a signature from that.

What you can do is to find the address of this function from PrimaryAttack.

Something like :

Code:
#include <amxmodx>
#include <fakemeta>
#include <hamsandwich>
#include <orpheu>
#include <orpheu_advanced>

const m_pPlayer = 41;
const Float:AwpAdjustedSpread = 0.08;

public plugin_init()
{
    register_plugin( "", "", "" );
    
    // Find AWPFire() address.
    new startAddress = OrpheuGetFunctionAddress( OrpheuGetFunctionFromClass( "weapon_awp", "PrimaryAttack", "CBasePlayerWeapon" ) );
    new fireAddress  = OrpheuGetNextCallAtAddress( startAddress, .number = 1 );
    
    // We can hook our function.
    OrpheuRegisterHook( OrpheuCreateFunction( fireAddress, "AWPFire", "CAWP" ), "OnAWPFire" );
}

public OnAWPFire( const weapon, const Float:spread, Float:cycleTime, const bool:useSemi )
{
    new player = get_pdata_cbase( weapon, m_pPlayer, 4 );
    OrpheuSetParam( 2, pev( player, pev_fov ) == 90 ? -AwpAdjustedSpread : 0.0 );
}

So, now, awp should have the same behavior like you were ducking all the time.


EDIT : forget the files :

functions/CAWP/AWPFire :

Code:

    "name"      : "AWPFire",

        {
            "type"  : "int"
        }
    ]
}

Code:
{
    "name"    : "PrimaryAttack",

Hey there I was wondering where do I put the first bit of code? I need this for a combat surf server. Thanks in advanced.
