Yay - Bots move to given vector location...

[stefanhendriks]

it would not suprise me if it did not work for bots...

[Cheeseh]

actually I just tried it with the bots, they got the origin ok, maybe you do need to "GetIServerEntity()" because i was still using that : *changes code on post*

[botman]

I think when the bots spawn, they rotate to face the direction (YAW) of the spawnpoint, then they stay facing that way for the rest of the game.

Try creating your own little CS map with T and CT spawn points that face 0 and 180 degrees and I bet the bots that spawn there will be facing each other (or facing away from each other, whatever).

botman, that would not suprise me, as the spawn points always have had control about the view angles (in Hl1 aswell). Though this was not 'default' in HL1 with fake clients if i remember correctly

[Gun-Nut]

got anymore good news?

[botman]

I'm sure when something changes, someone will post news. No news means nothing has changed.

SteveC delivered some very helpfull stuff; though its not the neatest way to do it

EDIT:
BUT there is no neater to way to do it as well!

[Cheeseh]

** Total Edit **

Alright, well I managed to get SteveC's CBaseEntity trick to work with my bots and got my bots to follow me whilst they look in the same direction (they don't look at me to follow me).

I have an example movie of a bot doing this here:

http://rcbot.bots-united.com/downloa...er/botmove.zip

The movement is actually the same as HL1 but the QAngles were between 0 and 360 instead of -180 and 180, which was confusing me.

PHP Code:

void CBot :: doMove ()
{
    // Temporary measure to make bot follow me when i make listen serevr
    setMoveTo(CBotGlobals::entityOrigin(INDEXENT(1)));

    if ( moveToIsValid () )
    {
        float flMove = 0.0;
        float flSide = 0.0;

        m_fIdealMoveSpeed = 320;

        // fAngle is got from world realting to bots origin, not angles
        float fAngle = CBotGlobals::yawAngleFromEdict(m_pEdict,m_vMoveTo);
        // fl Move is percentage (0 to 1) of forward speed,
        // flSide is percentage (0 to 1) of side speed.
        
        float radians = fAngle * 3.141592f / 180.0f; // degrees to radians
        flMove = cos(radians);
        flSide = sin(radians);

        m_fForwardSpeed = m_fIdealMoveSpeed * flMove;

        // dont want this to override strafe speed if we're trying 
        // to strafe to avoid a wall for instance.
        if ( m_fStrafeTime < engine->Time() )
        {
            // side speed 
            m_fSideSpeed = m_fIdealMoveSpeed * flSide;
        }

        // moving less than 1.0 units/sec? just stop to 
        // save bot jerking around..
        if ( fabs(m_fForwardSpeed) < 1.0 )
            m_fForwardSpeed = 0.0;
        if ( fabs(m_fSideSpeed) < 1.0 )
            m_fSideSpeed = 0.0;
    }
    else
    {    
        m_fForwardSpeed = 0;
        // bots side move speed
        m_fSideSpeed = 0;
        // bots upward move speed (e.g in water)
        m_fUpSpeed = 0;
    }
} 


To get the angle, here is the code i used:

PHP Code:

float CBotGlobals :: yawAngleFromEdict (edict_t *pEntity,Vector vOrigin)
{
    float fAngle;
    QAngle qBotAngles = entityEyeAngles(pEntity);
    QAngle qAngles;
    Vector vAngles;

    vAngles = vOrigin - entityOrigin(pEntity);

    // Just get the angles from world
    VectorAngles(vAngles,qAngles);
    
    // NEED to put 0-360 angles from -180 to 180 to get negative and positive values
    fixFloatAngle(&qBotAngles.y);
    //fAngle = qAngles.y; // world angles
    fAngle = qBotAngles.y - qAngles.y;

    fixFloatAngle(&fAngle);

    return fAngle;
} 


you NEED CBaseEntity to get eye angles

PHP Code:

QAngle CBotGlobals :: entityEyeAngles ( edict_t *pEntity )
{
    CBaseEntity *pBaseEntity = CBaseEntity::Instance(pEntity);

    return pBaseEntity->EyeAngles();
}

yes, i got this working too, you can see it in the ubframework alpha template.

currently my css bots walk around de_cbble using waypoints! yay.

[Cheeseh]

crap well when I try it again while changing the viewangles they move all over the place, I think there might be something else to do with the getting the right angle from either world or player forward vector, I'm still a bit unsure
