Do you just want to turn the player around backwards? If so try something like this:

PHP Code:

    [...]

    float fAngles[3];
    GetClientEyeAngles(client, fAngles);

    fAngles[1] += 180.0;
    NormalizeAngle(fAngles[1]);

    TeleportEntity(client, NULL_VECTOR, fAngles, NULL_VECTOR);

    [...]

void NormalizeAngle(float &angle)
{
    while(angle < -180.0)
        angle += 360.0;

    while(angle > 180.0)
        angle -= 360.0;
}

Why on earth are you using FloatAdd instead of +?

Thank you so much! My problem was to make a turn the entity(Drone) face to the calling player.
Only 3 lines of code solved this problem.

PHP Code:

client_angle[1] += 180.0;                                                     
if(client_angle[1] < -180.0) client_angle[1] += 360.0;
if(client_angle[1] > 180.0)  client_angle[1] -= 360.0; 


Video where is used this code

Probably for smooth turning.

There's no difference between the two (the operator and FloatAdd).

[tonline_kms65]

PHP Code:

drone_angle[1] = FloatAdd(drone_angle[1], 2.0); 


or

PHP Code:

drone_angle[1] = drone_angle[1] + 2.0; 


In principle Yes, I agree.

FloatAdd is the native that implements the + operator, that is literally its purpose, it should never be used directly (and it is likely any code using the internal Float* natives will break in the future, they are internal API).
