PHP Code:

public function(id)
    new Float:velocity[3];
    entity_get_vector(id, EV_VEC_velocity, velocity);
    
    velocity[0] = -velocity[0] * 2.0
    velocity[1] = -velocity[1] * 2.0
    velocity[2] = -velocity[2] * 2.0
    
    entity_set_vector(id, EV_VEC_velocity, velocity); 


When the player stay motionless his velocity is 0.0, how can i push him backward. My goal is when the function is called to push away all players in the range.

Figure it out urself from here, its from a grenade from one of my plugins.

PHP Code:

public what(id)
{
    static Team; Team = pev(Ent, pev_team)
    static Float:Origin[3]; pev(Ent, pev_origin, Origin)
    static TeamCheck; TeamCheck = 0
    static Float:Origin2[3], Float:Velocity[3];
    for(new i = 1; i <= g_MaxPlayers; i++)
    {
        if(!is_user_alive(i)) continue;
        if(pev(Ent, pev_owner) == i) continue;
        TeamCheck = (_:cs_get_user_team(i) == Team)
        if(TeamCheck) continue;
        if(entity_range(Ent, i) > float(EXPLUSIVE_RADIUS)) continue;
        pev(i, pev_origin, Origin2)
        if(is_wall_between_points(Origin, Origin2, 0)) continue;
        
        Get_SpeedVector(Origin, Origin2, float(EXPLUSIVE_POWER), Velocity)
        set_pev(i, pev_velocity, Velocity)
    }
}

stock Get_SpeedVector(const Float:origin1[3],const Float:origin2[3],Float:speed,Float:new_velocity[3])
{
    new_velocity[0] = origin2[0] - origin1[0]
    new_velocity[1] = origin2[1] - origin1[1]
    new_velocity[2] = origin2[2] - origin1[2]
    new Float:num = floatsqroot(speed*speed / (new_velocity[0]*new_velocity[0] + new_velocity[1]*new_velocity[1] + new_velocity[2]*new_velocity[2]))
    new_velocity[0] *= (num * 2.0)
    new_velocity[1] *= (num * 2.0)
    new_velocity[2] *= (num / 2.0)
}

You need to calculate the reversed vector between a point(the pusher?) and player's origin, and you've got yourself the push velocity.

[Depresie]

There are way too many plugins that do that...

Look for knockback grenade for example...
Btw, 0 x 2.0 = 0...

You shall consider that If a player turns on 180 degrees and You apply this command then he will be pushed in the other side.

For example if you make a ability for Warcraft mode to push all players away from you then if he turns with the face back from you then he will be pushed to you and players can use this vulberability to trick plugin.

Nonsence. You are using the coordinates of two points when calculating the velocity vector. View angles are not considered at all.

Yes, i meant this in case he will try use the other method.
