compare vpoint - player's looking position

[feanor]

start = eAttacker getRealEye();
fw = anglestoforward(self getplayerangles());
end = start + maps\mp\_utility::vectorscale( fw, 10000 );


trace = bulletTrace(start, end, true, undefined);

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?

[voron00]

vPoint is the point of where the damage was taken, not bullet fired.

[feanor]

not bullet fired.
wut?

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?



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_std/blob/master/utils.gsc#L184

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

crazybot silent aim Aimbot fov=1 Aimbot fov=2 Aimbot fov=3 that's the problem:confused:

[serthy]

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


trace = bulletTrace( start , end , true , attacker );

if( !isDefined( trace["entity"] ) || !isPlayer( trace["entity"] ) || trace["entity"] != victim || distance( trace["position"] , vPoint ) > 4 )
iPrintLn( "silent aim" );

If player kill enemy in VERY SUPER SPEED MOUSE :D?

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.

check( eVictim , eInflictor , eAttacker , iDamage , iDFlags , sMeansOfDeath , sWeapon , vPoint , vDir , sHitLoc , timeOffset )
{

start = eAttacker getRealEye();
fw = anglestoforward(eAttacker getplayerangles());
end = start + maps\mp\_utility::vectorscale( fw, 10000 );


trace = bulletTrace(start, end, true, eAttacker);


if( trace["position"] == vPoint )
return false ;

iPrintln("silent aim detected");
return true;
}

getRealEye()
{
player = self;

stance = player getStance();

offset = 0;
switch (stance)
{
case "stand": offset = 20; break;
case "duck": offset = 0; break;
case "lie": offset = -30; break;
//default: offset = getcvarint("offset");
}

realEye = player getEye() + (0,0,offset);
return realEye;
}



If player kill enemy in VERY SUPER SPEED MOUSE :D?

it happens in same frame , i dont think so it will be wrong


vPoint is the point of where the damage was taken, not bullet fired.

how they cant be the same ? so there is a way to detect it ?

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:



import numpy as np

def veclength(vec):
return np.sqrt( dot(vec, vec) )
def dot(a, b):
return a[0]*b[0] + a[1]*b[1] + a[2]*b[2]
def scale(vec, s):
return [ vec[0]*s, vec[1]*s, vec[2]*s ]
def a_minus_b(a, b):
return [ a[0]-b[0], a[1]-b[1], a[2]-b[2] ]
def normalize(vec):
l = veclength(vec)
return [ vec[0]/l, vec[1]/l, vec[2]/l ];

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_a, player_from);
dir_b = a_minus_b(player_to_b, player_from);
dir_c = a_minus_b(player_to_c, player_from);

dir_a = normalize( dir_a )
dir_b = normalize( dir_b )
dir_c = normalize( dir_c )

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

print("dot(dir_a, dir_b)", dot(dir_a, dir_b))
print("dot(dir_a, dir_c)", dot(dir_a, dir_c))


Output:



('dir_a', [0.0, 0.0, 1.0])
('dir_b', [0.0, 0.0, 1.0])
('dir_c', [0.0, -0.033314830232638482, 0.99944490697915433])
('dot(dir_a, dir_b)', 1.0)
('dot(dir_a, dir_c)', 0.99944490697915433)

Hehe, made this anti-silent-aim about two-three weeks ago and what can I say: sometimes it can react to lag players, so use some minimal distance between that points and ban players only after few reacts (5-10 maybe). And this works for me.

Also, I made anti-simple-aim. That's what maxdamage99 already said:

If player kill enemy in VERY SUPER SPEED MOUSE :D?

Working good aswell.
