Hello. I have been thinking about changing speed of attacking and distance of hitting with a knife.

I have already done this in CS 1.6:

PHP Code:

//Code for doubleing speed
RegisterHam(Ham_Weapon_PrimaryAttack, "weapon_knife", "KnifeAttack_Post", 1);
RegisterHam(Ham_Weapon_SecondaryAttack, "weapon_knife", "KnifeAttack_Post", 1);

public KnifeAttack_Post(ent){
    new id;
    id=entity_get_edict(ent, EV_ENT_owner);
    
    for(new i=46; i<=48; i++)
        set_pdata_float(ent, i, (get_pdata_float(ent, i, 4)*2.0, 4)

    return HAM_IGNORED;
}

//Code for doubleing distance
register_forward(FM_TraceLine, "TraceLine", 0);


public TraceLine(Float:vecStart[3], Float:vecEnd[3], conditions, id, ptr){
    if(!IsPlayerAlive(id))
        return FMRES_IGNORED;
    if(get_user_weapon(id)!=CSW_KNIFE)
        return FMRES_IGNORED;

    static Float:flFraction, Float:vecAngles[3], Float:vecForward[3], attack_mod, Float:Distance;
    pev(id, pev_v_angle, vecAngles);
    engfunc(EngFunc_MakeVectors, vecAngles);

    global_get(glb_v_forward, vecForward);

    attack_mod=RoundFloat((vecStart[0]-vecEnd[0])/vecForward[0]*-1.0);

    if(attack_mod!=48 && attack_mod!=32)
        return FMRES_IGNORED;

    Distance=2.0; //default 1.0
    Distance*=attack_mod;

    if(Distance<=0)
        return FMRES_IGNORED;

    get_tr2(ptr, TR_flFraction, flFraction);

    xs_vec_mul_scalar(vecForward, Distance, vecForward);
    xs_vec_add(vecStart, vecForward, vecEnd);

    engfunc(EngFunc_TraceLine, vecStart, vecEnd, conditions, id, ptr);

    return FMRES_SUPERCEDE;
} 


I have experimented with SDKhooks on this matter:

PHP Code:

public void OnClientPutInServer(int client)
{
    if (false == IsValidClient(client))
    {
        return;
    }

    SDKHook(client, SDKHook_FireBulletsPost, FireBulletsPost);
    SDKHook(client, SDKHook_TraceAttack, TraceAttack);
}


public void FireBulletsPost(int client, int shots, const char[] weaponname)
{
    sendDebugMessage("FireBulletsPost");
}

public Action TraceAttack(int victim, int& attacker, int& inflictor, float& damage, int& damagetype, int& ammotype, int hitbox, int hitgroup)
{
    sendDebugMessage("TraceAttack");
} 


But this only prints a message when i shoot somebody and deal damage, but not with a knife.

I have also gotten my hands on Prop Data Knife properties. I have:

PHP Code:

    SetEntPropFloat(iWeaponTemp, Prop_Send, "m_flNextPrimaryAttack", GetGameTime() + 1.1);
    SetEntPropFloat(iWeaponTemp, Prop_Send, "m_flNextSecondaryAttack", GetGameTime() + 1.1); 


which should set the next attack to be avalible in 1.1 seconds. The problem is, how do i catch when the players is attacking with a knife?

The second Prop Data that caught my attention were:

PHP Code:

- m_fMinRange1 (Offset 2440) (Save)(4 Bytes)
- m_fMinRange2 (Offset 2444) (Save)(4 Bytes)
- m_fMaxRange1 (Offset 2448) (Save)(4 Bytes)
- m_fMaxRange2 (Offset 2452) (Save)(4 Bytes) 


But the question is, will this change the range of attacking? When do i change it? At player spawn? At weapon change? At weapon entity spawn?

Use OnPlayerRunCmd -> Check whether active weapon is knife || bayonet -> Check if buttons & IN_ATTACK || buttons & IN_ATTACK2 -> You can try the following (not sure if it works):

PHP Code:

SetEntPropFloat(weaponEnt, Prop_Send, "m_flPlaybackRate", Amount); 


Revert back to normal playbackrate after a second or two according to your preference.

For detect when attack with knife you can use too:

PHP Code:

#include <sourcemod>

public void OnPluginStart()
{
    HookEvent("weapon_fire", EventWeaponFire); 
}

public Action EventWeaponFire(Handle event, char[] name, bool dontBroadcast)
{
    char szWeapon[32];
    GetEventString(event, "weapon", szWeapon, sizeof(szWeapon));
    if(!StrEqual(szWeapon, "weapon_knife") && !StrEqual(szWeapon, "weapon_bayonet"))
        return;
        
    int client = GetClientOfUserId(GetEventInt(event, "userid")); // player index
    
    // attacking with knife
    int ActiveWeapon = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon"); 
    SetEntPropFloat(ActiveWeapon, Prop_Send, "m_flNextPrimaryAttack", GetGameTime() + 1.1);
    SetEntPropFloat(ActiveWeapon, Prop_Send, "m_flNextSecondaryAttack", GetGameTime() + 1.1);
}

I think OnPlayerRunCmd repeats itself too much so i want to avoid using. But thank you for your suggestion

That works very well, thank you. I have tested it and the secondary knife attack is not being hooked. So this does not suit my needs



I have searched again for a while and stumbled upon this: https://forums.alliedmods.net/showth...=307436&page=2
Soundhooking does work well. This is working code:

PHP Code:

#include <sdktools_sound>

AddNormalSoundHook(SoundHook);

public Action SoundHook(int clients[MAXPLAYERS], int& numClients, char sample[PLATFORM_MAX_PATH],
                 int& entity, int& channel, float& volume, int& level, int& pitch, int& flags,
                 char soundEntry[PLATFORM_MAX_PATH], int& seed)
{
    if (StrContains(sample, "knife/knife_", false) == -1)
    {
        return Plugin_Continue;
    }

    if (StrContains(sample, "deploy", false) > -1)
    {
        return Plugin_Continue;
    }

    int   client              = GetEntPropEnt(entity, Prop_Data, "m_hOwnerEntity");
    int   activeWeapon        = GetEntPropEnt(client, Prop_Send, "m_hActiveWeapon");
    float gameTime            = GetGameTime();
    float nextPrimaryAttack   = GetEntPropFloat(activeWeapon, Prop_Send, "m_flNextPrimaryAttack");
    float nextSecondaryAttack = GetEntPropFloat(activeWeapon, Prop_Send, "m_flNextSecondaryAttack");
    float modifier            = 0.5; //modify here

    nextPrimaryAttack   = ((nextPrimaryAttack - gameTime) * modifier) + gameTime;
    nextSecondaryAttack = ((nextSecondaryAttack - gameTime) * modifier) + gameTime;

    SetEntPropFloat(activeWeapon, Prop_Send, "m_flNextPrimaryAttack", nextPrimaryAttack);
    SetEntPropFloat(activeWeapon, Prop_Send, "m_flNextSecondaryAttack", nextSecondaryAttack);

    sendDebugMessage("SoundHook buffing attack speed by %f", modifier);

    return Plugin_Continue;
} 


I am satisfied with this solution. But the knife hit distance is still remaining. I will try to figure it out but if anyone has some ideas on how to get that, i would very much appreciate some brainstorming

[Vasto_Lorde]

I have managed to write this code:

PHP Code:

    char PropsToCheck[][] = {
        "m_fMaxRange1",
        "m_fMinRange1",
        "m_fMaxRange2",
        "m_fMinRange2",
    };
    float distance = 100;

    for (int i = 0; i < sizeof(PropsToCheck); i++)
    {
        if (HasEntProp(ent, Prop_Data, PropsToCheck[i]))
        {
            sendDebugMessage("%s value is %f, setting to %f", PropsToCheck[i], GetEntPropFloat(ent, Prop_Data, PropsToCheck[i]), GetEntPropFloat(ent, Prop_Data, PropsToCheck[i]) * distance);
            SetEntPropFloat(ent, Prop_Data, PropsToCheck[i], GetEntPropFloat(ent, Prop_Data, PropsToCheck[i]) * distance);
        }
        else {
            sendDebugMessage("No %s prop", PropsToCheck[i]);
        }
    } 


It actually changes the values, but nothing happens in game. Also the HasEntProp says that those properties does not exist when i try to do this with Prop_Send.

I have also checked other props that had some keywords like "range" in them, but it did not detect those props on Knife Entity. Any other ideas?

The slash/stab distance is hard coded and there's no netprop for it. I made a simple memroy patch that can change the stab distance

Now for the following question, can you make it filter per player by altering the variable whenever the knife would be swung.

I definitely have ideas for making the baseball bat Gun XP Mod Unlock Shop allow it
