Hi.
Does anyone know, how to optimise code for multiplayer to avoid getting Syncbads?
I already know, that you should use RelativeToAbsoluteSmooth() instead of RelativeToAbsolute() (same thing for AbsoluteToRelative() ), but my code still causes bad syncs.

The code itself doesn't contain any rand() functions, so it should work theoretically, but for some reason it doesn't.

Pause the game on bad syncs, set cli_bDumpSync to 1 both on server and client. This will output Temp/SyncDump.txt on both server and client. Compare those files, and you know what's getting out of sync.

Thanks for replying!

The reason of bad syncs is that client and server return different values for GetPlacement()... I think I should get predicted placement for client. There are 2 functions in EnemyBase class called "ShootPredictedProjectile" and "CalculatePredictedPosition". Perhaps they contain the solution to all my problems...

hello,I need your help, I have a code that corresponds to a group of enemies with a "0" became friendly, and I have a parameter that is responsible for the fact that they follow the player permanently, as bots in a mod that's actually Parse error (by Dwk) code:
Friendship()
{
m_bRunningToFriend = TRUE;
GetWatcher()->SendEvent(EStart());

// while there is a valid marker, take values from it
if (m_penFriend != NULL) {
if(!(m_penFriend->GetFlags()&ENF_ALIVE)) {
StopMoving();
StandingAnim();
m_penFriend = NULL;
m_bRunningToFriend = FALSE;
return EReturn();
}
CEntity *pem = &*m_penFriend;
// the marker position is our new start position for attack range
CPlacement3D plFriend = m_penFriend->GetPlacement();
/*plFriend.AbsoluteToRelative(GetPlacement());
plFriend=CPlacement3D(plFriend.pl_PositionVector/2.0f,plFriend.pl_OrientationAngle);
plFriend.RelativeToAbsolute(GetPlacement());*/
m_vStartPosition = plFriend.pl_PositionVector;
m_vDesiredPosition = m_vStartPosition;
// use attack speeds
m_fMoveSpeed = GetProp(m_fAttackRunSpeed)*m_fSpeedMultiplier;
m_aRotateSpeed = GetProp(m_aAttackRotateSpeed);
// start running anim
RunningAnim();

autocall MoveToDestination() EReturn;

// wait a bit always (to prevent eventual busy-looping)
autowait(0.05f);
} // when no more markers

// stop where you are
StopMoving();
StandingAnim();
m_bRunningToFriend = FALSE;

// return to called
return EReturn();
};
but, I had a problem (
1) as even after the big fight, they stand as driven ((
2) if for him (that is, a group of enemies 0) shoots a player, they also stand (which I already corrected))
Watcher.es already in the mood (I was helping a friend set it up)
help if we have not seen anything that will recommend something.

m_vStartPosition = plFriend.pl_PositionVector;
m_vDesiredPosition = m_vStartPosition;

I think, the problem is here. The destination and start positions are the same. Try this:

m_vStartPosition = GetPlacement().pl_PositionVector;
m_vDesiredPosition = plFriend.pl_PositionVector;

But I'm not sure whether this is the source of the problem or not.

BTW,

plFriend.RelativeToAbsolute(GetPlacement());

I know that this line is commented, but it is better to use RelativeToAbsoluteSmooth() instead of RelativeToAbsolute().

hmm, did not help ((I want to heir class "CEnemyBase" follow the player, at any distance, and when you touch to it.
