    compare vpoint - player's looking position

    PHP Code:
        start eAttacker getRealEye();   
        
    fw anglestoforward(self getplayerangles());
        
    end start maps\mp\_utility::vectorscalefw10000 );
        

        
    trace bulletTrace(startendtrueundefined); 
    i am trying to fix silent aim.

    its the position of player's looking isnt it ?

    and vPoint variable in callbackplayerdamage is the point the player hits on the eVictim isnt it ?

    but if i compare it they dont give me the same result ?(without cheat) why?

    vPoint is the point of where the damage was taken, not bullet fired.
    sudo apt-get rekt

    No clue what you are trying to do, but you take the eye pos from eAttacker, but add the forward direction of self to it. Do you mean this?

    PHP Code:
    fw anglestoforward(eAttacker getplayerangles()); 
    And since getRealEye isn't a default function, just help people to understand your code by linking to its parts: https://github.com/kungfooman/cod2_s...utils.gsc#L184

    For debugging, you can either print the coordinates or just spawn some entities to that position

    When fixing silent aim, maybe do something like this (after you get the players eye-pos based on the current stance):

    PHP Code:
    trace bulletTracestart end true attacker );

    if( !
    isDefinedtrace["entity"] ) || !isPlayertrace["entity"] ) || trace["entity"] != victim || distancetrace["position"] , vPoint ) > )
        
    iPrintLn"silent aim" );

    with silent aim if player shoots (x , y , z) point , his bullets hits to (r , s , t) point. i am trying to find these points , thats what i am trying to do.

    i figured out if player hits to for example near of boots , bullettrace doesnt stop. it ends on the ground. actually eattacker hits to evictim but it is not same in bullettrace

    You just need to get the two directional vectors, which is direction = from - to; (and normalize those two directions)

    a) from getrealeye to bullet hitpoint
    b) from getrealeye to getrealeye += foward * 10000

    Then do iprintln(vectorDot(a, b)); and you should understand it, basically it gives you the angle between the two vectors

    YouTube has enough videos which explains dot product

    Made some example code for IPython, for quick testing:

    PHP Code:
    import numpy as np

    def veclength
    (vec):
        return 
    np.sqrtdot(vecvec) )
    def dot(ab):
        return 
    a[0]*b[0] + a[1]*b[1] + a[2]*b[2]
    def scale(vecs):
        return [ 
    vec[0]*svec[1]*svec[2]*]
    def a_minus_b(ab):
        return [ 
    a[0]-b[0], a[1]-b[1], a[2]-b[2] ]
    def normalize(vec):
        
    veclength(vec)    
        return [ 
    vec[0]/lvec[1]/lvec[2]/];

    player_from = [100,100,100]
    player_to_a = [100,100,130]
    player_to_b = [100,100,130]
    player_to_c = [100,99,130]

    dir_a a_minus_b(player_to_aplayer_from);
    dir_b a_minus_b(player_to_bplayer_from);
    dir_c a_minus_b(player_to_cplayer_from);

    dir_a normalizedir_a )
    dir_b normalizedir_b )
    dir_c normalizedir_c )

    print(
    "dir_a"dir_a)
    print(
    "dir_b"dir_b)
    print(
    "dir_c"dir_c)

    print(
    "dot(dir_a, dir_b)"dot(dir_adir_b))
    print(
    "dot(dir_a, dir_c)"dot(dir_adir_c)) 
    Output:

    PHP Code:
    ('dir_a', [0.00.01.0])
    (
    'dir_b', [0.00.01.0])
    (
    'dir_c', [0.0, -0.0333148302326384820.99944490697915433])
    (
    'dot(dir_a, dir_b)'1.0)
    (
    'dot(dir_a, dir_c)'0.99944490697915433
