Thread: W2S and other stuff

Hello !

I'm making my ******* ESP, but i've a problem :

Look at my code :

Code:

float VectorAngle(const vec3_t a, const vec3_t b)
{
    float length_a = VectorLength(a);
    float length_b = VectorLength(b);
    float length_ab = length_a*length_b;
    if( length_ab==0.0 )
    { 
        return 0.0; 
    }
    else
    { 
        return (float) (acos(DotProduct(a,b)/length_ab) * (180.f/M_PI)); 
    }
}

bool WorldToScreen(vec3_t Origin, float *ScreenX, float *ScreenY)
{
    float xzi, yzi;
    vec3_t Local, Transformed;
    vec3_t Fwd, Right, Up;

    #define xcenter (cg->Refdef.Width / 2.f)
    #define ycenter (cg->Refdef.Height / 2.f)

    AngleVectors(cg->Refdef.RefdefViewAngles, Fwd, Right, Up);
    VectorSubtract(Origin, cg->Refdef.Vieworg, Local);

    Transformed[0] = DotProduct(Local, Right);
    Transformed[1] = DotProduct(Local, Up);
    Transformed[2] = DotProduct(Local, Fwd);

    if(Transformed[2] < 0.01f)
        return false;

    xzi    = xcenter / Transformed[2] * (90.0f / cg->Refdef.Fovx);
    yzi    = ycenter / Transformed[2] * (90.0f / cg->Refdef.Fovy);
    
    *ScreenX = xcenter + (xzi * Transformed[0]);
    *ScreenY = ycenter - (yzi * Transformed[1]);

    return true;
}

In endscene : (Yes thats in D3D)

float screen[1];

for( int x = 0; x < 63; x++ )
{
if(WorldToScreen(ci[x].LerpOrigin, &screen[0], &screen[1]))
{
    uFont->DrawText(ci[x].Name, screen[0], screen[1]);
}
}

It doesn't draw anything, just :


Thanks

Check your structs, log them to make sure there getting the correct information through.

Yes, they're good, but i think my cg refdef isn't good, but i've took it from sinner's src, i've tried to print the refdefviewangles :

Code:

    sprintf(g_Buffer, "RefDefViewAngles : %ld, %ld, %ld", cg->RefdefViewAngles[0], cg->RefdefViewAngles[1], cg->RefdefViewAngles[2] );
    uFont->DrawText(g_Buffer, 10, 100);

But i got 0,0,0

%f

try using deltasharks w2s from OGC

TBH just multiply your refdef->fov_x and refdef->fov_y by 100 and enjoy your ESP

Assuming (of course) your structs are correct...

Looks better, i've tried the W2S from OGC, and multiplied fovx by 100, but i've a problem now, when i move my mouse, the "over here" are moving, and when i look a player, the "over here" disappear.


Here's the code :

Code:

int screen[2];

for( int x = 0; x < 63; x++ )
{
if(WorldToScreen(ci[x].LerpOrigin, screen)==0)
{
    if(GetAsyncKeyState(VK_SHIFT)&1)
        Log("Screen X : %i, Screen Y : %i", screen[0], screen[1]);

    uFont->DrawText("over here", screen[0], screen[1]);
}
}

Thanks

ofc they move..they are other players lol...

Hmmm, look on the picture, i'm not looking at the ennemies, but at the wall, and it's the border of the map.

Up :-\

i know i'm bumping a week old thread but it is most certainly a problem with refdef (either viewangles or viewaxis)

try using the structs posted on gamedeception
