This is a problem that has been discused for some time here on amxx.
How to make a gun have semirecoil.

How do we do this?
Well we need 2 modules:
FakeMeta and HamSandWich

First we need to learn how to catch a weapon fire in HamSandWich.
We register first the normal forward becouse we want to get the punchangle before the shot.
We register the next forward as post becouse that is the moment when we can manipulate the punchangle (the recoil)

PHP Code:

// In plugin_init()
RegisterHam(Ham_Weapon_PrimaryAttack, "weapon_deagle", "fw_primary_attack")
RegisterHam(Ham_Weapon_PrimaryAttack, "weapon_deagle", "fw_primary_attack_post",1) 


In order to do this efficently we need 2 defines:

PHP Code:

// We use this bitsum to avoid using weapons that don't have recoil. (of course a nade doesn't have :P)
#define NO_RECOIL_WEAPONS_BITSUM  ( 1 << CSW_KNIFE | 1 << CSW_HEGRENADE | 1 << CSW_FLASHBANG | 1 << CSW_SMOKEGRENADE | 1 << CSW_C4 )
#define MAX_PLAYERS 32
// Here we store the punch angle before shot
new Float:cl_pushangle[MAX_PLAYERS + 1][3] 


If you want to catch all the weapons it is not hard.

PHP Code:

    new weapon_name[24]
    
    for ( new i = 1; i <= 30; i+ ) 
    { 
        if (!(NO_RECOIL_WEAPONS_BITSUM & 1 << i) && get_weaponname(i, weapon_name, 23))
        { 
            RegisterHam( Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack" )
            RegisterHam( Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack_post", 1 )
        } 
    } 


We must remember that the forward will be called on the entities! Not on the players! So in order to get the player we need to find the entity owner.

PHP Code:

// The alive check is already done and the entity is valid 
public fw_primary_attack(ent)
{
    new id = pev(ent,pev_owner)
    // Save the punchangle before shot
    pev(id,pev_punchangle,cl_pushangle[id])
    
    return HAM_IGNORED
}

public fw_primary_attack_post(ent)
{
    // get the owner of the entity (player)
    new id = pev(ent,pev_owner)

    // Here we can get the recoil or punchangle of the weapon fire
    new Float:punch[3]
    pev(id,pev_punchangle,punch)
    punch[0] -= cl_pushangle[id][0]
    punch[1] -= cl_pushangle[id][1]
    punch[2] -= cl_pushangle[id][2]

    // We print it to see the values in this case but this is the best place
    // where we can manipulate it
    client_print(id,print_chat,"%0.2f , %0.2f, %0.2f",punch[0],punch[1],punch[2])
    
    return HAM_IGNORED
} 


If we put it all together then we will have this:

PHP Code:

#define NO_RECOIL_WEAPONS_BITSUM  ( 1 << CSW_KNIFE | 1 << CSW_HEGRENADE | 1 << CSW_FLASHBANG | 1 << CSW_SMOKEGRENADE | 1 << CSW_C4 )
#define MAX_PLAYERS 32
// Here we store the punch angle before shot
new Float:cl_pushangle[MAX_PLAYERS + 1][3]

public plugin_init()
{
    new weapon_name[24]
    // Register all the weapons that we need
    for ( new i = 1; i <= 30; i++ ) 
    { 
        if (!(NO_RECOIL_WEAPONS_BITSUM & 1 << i) && get_weaponname(i, weapon_name, 23))
        { 
            RegisterHam( Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack" )
            RegisterHam( Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack_post", 1 )
        } 
    }
}

// The alive check is already done and the entity is valid 
public fw_primary_attack(ent)
{
    new id = pev(ent,pev_owner)
    // Save the punchangle before shot
    pev(id,pev_punchangle,cl_pushangle[id])
    
    return HAM_IGNORED
}

public fw_primary_attack_post(ent)
{
    // get the owner of the entity (player)
    new id = pev(ent,pev_owner)

    // Here we can get the recoil or punchangle of the weapon fire
    new Float:punch[3]
    pev(id,pev_punchangle,punch)
    punch[0] -= cl_pushangle[id][0]
    punch[1] -= cl_pushangle[id][1]
    punch[2] -= cl_pushangle[id][2]

    // We print it to see the values in this case but this is the best place
    // where we can manipulate it
    client_print(id,print_chat,"%0.2f , %0.2f, %0.2f",punch[0],punch[1],punch[2])
    
    return HAM_IGNORED
} 


My plugin based on this tutorial: Recoil Control

And that's all! Hope that you guys find it usefull!

About the second code, you should avoid to create var into a loop, also you can directly check get_user_weaponame(), it will return the weapon name length and 0 if weapon not found. I should be :

    new weapon_name[24];
    
    for (new i=1;i<=30;i++) 
    { 
        // We get the weapon_name in our string, using the id of the weapon which is i that is why it starts from 1 and goes till 30 
        // We check if we have a valid weapon
        if ( get_weaponname(i, weapon_name, 23) )
        { 
            // We register the weapon's primary attack 
            RegisterHam(Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack_post",1) 
        } 
    }

About the third code, I think that pev_valid is useless, and is_user_alive() too in such forward. Also, Instead ot checking weapon which don't have recoil each time, just don't register theses weapons in the second code. Something like if i'm right :

    #define NO_RECOIL_WEAPONS_BITSUM  ( 1 << CSW_KNIFE | 1 << CSW_HEGRENADE | 1 << CSW_FLASHBANG | 1 << CSW_SMOKEGRENADE | 1 << CSW_C4 )
    
    new weapon_name[24];
    
    for ( new i = 1; i <= 30; i+ ) 
    { 
        if ( !( NO_RECOIL_WEAPONS_BITSUM & 1 << i ) && get_weaponname( i, weapon_name, 23 ) )
        { 
            RegisterHam( Ham_Weapon_PrimaryAttack, weapon_name, "fw_primary_attack_post", 1 );
        } 
    }

Something like that, should be enough :

public fw_primary_attack_post( ent ) 
{ 
    new id = pev( ent, pev_owner );
    
    new Float:punch[3];
    pev( id, pev_punchangle, punch );
    
    client_print(id,print_chat, "%0.2f , %0.2f, %0.2f", punch[0], punch[1], punch[2] ) 
}

Ok will update these days. I will be a little bit busy.
And I will add another thing to the tutorial that will make get the true recoil of the weapon. This method can produse small false pozitives

Updated the tutorial hope that everything is better now.

Nice, nice!

[alan_el_more]

good tutorial

[ot_207]

Updated some parts of the tutorial. There were some errors ...

Great, now we can go pwn noobs with da TMP!

On a side-note: it seems that, except for shotguns and deagle's, there is no client-side prediction of weapon's recoil (unlike CSS). This means if you have a ping greater than 0, you'll be seeing a delayed/incorrect recoil pattern when you shoot! And that explains the incredible amount of BS you get when spraying around...

Unfortunately that is the only problem...
