Re: Yay - Bots move to given vector location...
 
ahh god I'm so ignorant :(

The movement is the SAME !!

It's just that EyeAngles returns a angle from 0 to 360 instead of -180 to 180 I think.

So my old code works fine now (changed in post)... it works perfectly too, the last one was a bit dodgy

Re: Yay - Bots move to given vector location...
 
this is what i use:

Code:
Vector vMoveDir;
        Vector vLookDir;
       
        pBot->vLookAtVector = pBot->vMoveToVector; // ITS THE SAME
        vLookDir = pBot->vLookAtVector;        // look at this
        AngleVectors(AngleWeMoveTo, &vMoveDir); // get movement direction
       
        // move in vMoveDir
        // dot product vMoveDir onto vLookDir to get forward movement
       
        float fForwardDot=DotProduct(vMoveDir, vLookDir); // get the proportion of forwards
       
        Vector vRightLook, vUpLook;
        VectorVectors(vLookDir, vRightLook, vUpLook); // get the vector perpendicular to the forward vector
       
        float fSideDot=DotProduct(vMoveDir, vRightLook); // get the proportion of side
       
       
        cmd.forwardmove=fForwardDot*200.0f;
        cmd.sidemove=fSideDot*200.0f;

Works a treat doesn't it Stefan ;).

Oh and by the way people I think I've worked out how to get the bots to shoot at enemies, (human or bot). But I need to do some testing first, should have a result by the weekend.

Re: Yay - Bots move to given vector location...
 
got that working already :P

don't you just get the team Index from playerinfo and see if its different? Cos if they are it's an enemy.

Yeah, but to get the entity list there may be more than one technique, I'm using the edict list.

I guess we'll have a bot build off for a couple of weeks, then work together to produce a kick ass bot, once we know how everything works. Up for it?

Re: Yay - Bots move to given vector location...
 
hey stevec, thats what Bots-United is for... to work together on kick-ass bots. Or alteast, at a kick-ass-framework

my snippet:

Code:
void BotFindEnemy(bot_t *pBot)
{
        // FIXME: Make this use UTIL_TRACELINE some day?
        Vector vFrom, vTo;       
        Ray_t mRay;                // the ray itself
 CTraceFilterHitAll mTraceFilter;       
        CGameTrace tRay;        // the results
        CBaseEntity *pEnemyBaseEntity=NULL;
        if (pBot->pEnemy)
        {
                BotAttackEnemy(pBot);
                return;
        }
        float fDistance=9999;
        // scan for enemy activities
 for ( int i = 1; i <= 32; i++ )  // EVIL: shouldn't just assume maxplayers is 32!!!
 {
  edict_t *pPlayerEdict = INDEXENT( i );
 
                if (pPlayerEdict)  // valid edict               
                {                         
                        if (pPlayerEdict == pBot->edict)
                                continue; // do not check self
                        pEnemyBaseEntity = CBaseEntity::Instance(pPlayerEdict);// get the player entity
                        if (pEnemyBaseEntity == NULL)
                                continue; // failed
                        // Check if its a player. (thx botman for pointing me out on this <shame>)
                        if (!pEnemyBaseEntity->IsPlayer())
                                continue;
                        if ( !pPlayerEdict->IsFree() ) // valid client
                        {                 
                                // HACK HACK
                         
                                // ok, this COULD be our enemy, so check this team status                               
                                IPlayerInfo* pInfo = NULL;
                               
                                if (playerinfomanager)
                                        pInfo = playerinfomanager->GetPlayerInfo(pPlayerEdict);
               
                                if (pInfo == NULL || !pInfo)
                                        return; // get out, this wont work :S                                        */
                               
                                // Set team (in case the game dll changed it for us)
                                int iTeam = pInfo->GetTeamIndex();
                         
                                if (iTeam != pBot->iTeam)
                                {                                       
                                        // potential enemy
                                        vFrom = pBot->vMyOrigin;
                                        gameclients->ClientEarPosition( pPlayerEdict, &vTo );  // to = his origin
                                        // TODO: How to make sure it is in our viewangles?
                                        QAngle viewangles;
                                        UTIL_VectorAngles( pBot->vLookAtVector, viewangles );
                                        if (FInViewCone(vFrom, vTo, viewangles) == false)
                                                continue;
                                        //bool FInViewCone (Vector vStart, Vector vLookDir, QAngle viewangles)
                                        // CHECK if enemy is behind wall or not
                                       
                                        if (UTIL_DistanceBetween(vFrom, vTo) > fDistance)
                                                continue; // too far
                                        mRay.Init(vFrom,vTo); // init
                                       
                                        enginetrace->TraceRay(mRay, MASK_PLAYERSOLID, &mTraceFilter, &tRay);

                                        //if (pEnemyBaseEntity == NU
                                        // success
                                        if (tRay.fraction == 1.0 || tRay.m_pEnt == pEnemyBaseEntity)
                                                {
                                                // could be our enemy
                                                fDistance = UTIL_DistanceBetween(vFrom, vTo);
                                                // Set as our enemy for now
                                                pBot->pEnemy = pPlayerEdict;
                                        }
                                }
                        }               
                }
 }
}
Note:
my "FInViewCone" function... is a bit of a fuzz. I do not know if it works 100%, here it is. Btw, i did not notice odd behaviour just yet...

Code:
bool FInViewCone (Vector vStart, Vector vLookDir, QAngle viewangles)
{ 
  float flDot;
  Vector vMoveDir;
  // We move to this
  AngleVectors(viewangles, &vMoveDir);
 
  Vector vRightLook, vUpLook;       
  VectorVectors(vLookDir, vRightLook, vUpLook); // get the vector perpendicular to the forward vector
 
  Vector vDest = vLookDir-vStart;
  // vLookDir
  flDot = DotProduct(vDest, vLookDir);       
  //Msg("FlDOT=%f ", flDot); 
         
  if (fabs(flDot) > 0.50)  // 60 degree field of view
        {
          return TRUE;
        }
  else
        {
          return FALSE;
        }
}

Re: Yay - Bots move to given vector location...
 
OK, I'll help where I can then.

If you want to fix the //EVIL on the maxplayers you can get the max players when the ServerActivate function is called in the plugin part of the code.

And I think there is a get FOV function in the CBasePlayer class we can use, but I'll need to check. It will help with FOV when using snipers etc.

Re: Yay - Bots move to given vector location...
 
About maxplayers, yes i know, i am just really lazy to fix that ;)

for FOV, i did a quick search in the base class and the player class but did not find anything yet. I did not use "FOV" as keysearch though. :S Perhaps its there, but i think my function works? :)

Re: Yay - Bots move to given vector location...
 
I think I found out how to make bots switch weapons. You must pass in the wpnselect field of the usercmd struct the entity index of the weapon to select. It's not a bitfield like I initially thought. However since I have little clue so far on how to peek around entities, I have not been able to test.
