Hello. Does anybody knows how to limit player angle movement?
What I'm trying to achieve is a movement similar to a 2D game, so that the player can only move in 0, 90, 0 or 0, 270, 0 angles. So if I press a, the yaw angle will be 90, if I press d it must be 270. So kinda like an enforcement of 90 and 270, while the pitch and roll angles will always have to be 0. Even pressing W or S must retain these angles. Any ideas? Thanks !

On every player's think/frame force him your angles.

This won't work fine, if I set yaw angle to 90, the player will move to the right and not to the left when pressing a.

This means you need the opposite angle's value (270 or -90).
Also, do you change angle or view angle?

I just changed pev_angle.

Well, what I want is, when pressing W, the player will aim to the left. When pressing D, to the right. No ideas? -90 will make him aim to the left.

This is the way I used in my 'Tron'-mod,
not sure there is a better way but it worked.

(Maybe pev_fixangle is needed, if you want to force it)

PHP Code:

new Float:g_client_angle[33][3]

public client_spawn(client)
{
  pev(client, pev_v_angle, g_client_angle[client])
  g_client_angle[client][1] = 90.0
}

public client_PreThink(client)
{
    if(is_user_alive(client))
    {
        static client_button, client_oldbutton
        client_button = pev(client, pev_button)
        client_oldbutton = pev(client, pev_client_oldbuttons)

        if(client_button & IN_MOVERIGHT
          && ~client_oldbutton & IN_MOVERIGHT)
        {
            g_client_angle[client][1] -= 90.0
        }
        else if(client_button & IN_MOVELEFT
          && ~client_oldbutton & IN_MOVELEFT)
        {
            g_client_angle[client][1] += 90.0
        }
        set_pev(client, pev_angles, Float:g_client_angle[client])
        set_pev(client, pev_v_angle, Float:g_client_angle[client])
  }
}

    entity_set_int( index , EV_INT_fixangle , 1 );

Yes, but on TFC, for example, velocity is different according to the class. And on CS it's according to the holding weapon. So 230 is not a good value in this case.
Also, engine is not needed here since you're using FakeMeta, better use either engine or fakemeta.

EDIT: Maybe doing fVelocity[0] = -fVelocity[0]; will do the trick by using pev(id, pev_velocity, fVelocity) then applying the new velocity.
Will test tomorrow.

no no no no no no NO
