[hlcoders] RE: Blood not spawning for attacker?

2006-06-27 Thread Imperio59


Hey,
Well thank you Chris Janes for the fix, which I applied to the default
bullet code in FireBullets on around line 158 of sdk_player_shared, and
which fixed the blood problem.
Here's the fixed code (all we did was move out the CTakeDamage
initialise and calculations and the DispatchTraceAttack out of the #ifdef...

//Imperio59: Fix for blood not being correctly predicted...
   CTakeDamageInfo info( pevAttacker, pevAttacker, fCurrentDamage,
iDamageType );

#ifdef GAME_DLL
   ClearMultiDamage();
#endif
   CalculateBulletDamageForce( info, iBulletType, vecDir, tr.endpos );
   tr.m_pEnt-DispatchTraceAttack( info, vecDir, tr );
#ifdef GAME_DLL
   TraceAttackToTriggers( info, tr.startpos, tr.endpos, vecDir );
   ApplyMultiDamage();
#endif

I'm gonna add this to the wiki list.
Enjoy!

I'm not so hot on that solution.  As I understand it, for a normal bullet
weapon, there are two parts to the impact effect:

1.  Sparks/flecks/impact decal
2.  Blood

Only (1) should be predicted, because it doesn't require any server
verification.  Since these are minor effects (not gameplay-affecting), it's
all right for the client to simulate them.  Blood, however, is another
matter.  Blood spray is a visual confirmation to the player that he has
indeed hit the target; and _this_ is not something you can afford to
mispredict.  Thus, the server should take care of telling the client to spawn
the blood sprite.

Now, as for your weapon, you'll need to do some thinking on this matter.  For
your particular mod, is the blood splatter gameplay-affecting or not?  It
makes sense for you that sparks should be predicted, but I'm not sure that
blood should be the same way.  Even if you do decide to predict blood, I
would advise against changing it in sdk_player_shared, as this would affect
_all_ weapons across your mod, even more conventional ones for which the
player might expect conventional response.

So, basically, your beef is with the prediction system, not sdk_player_shared.
Watch out for hasty fixes :-P

Re: [hlcoders] RE: Blood not spawning for attacker?

2006-06-27 Thread John Sheu

I'm submitting this in a separate e-mail, since I'm not sure that it's
completely in line with the subject of the thread, but I do think that it
might have some useful points in common.

So, with regards to my question of a while ago that went conveniently
unaswered:  What kind of timebase is the client rendering on?  Does it try to
be exactly synchronized with the server, regardless of latency, or does it
just monotonically increase its current time as it receives packets?

What I'm doing is creating a tempent with a fixed velocity.  Every client
frame, it simulates itself forward along that velocity.  Now, if I just
create it as usual, by the time the creation command gets to the client, the
tempent will already be somewhere behind where it should be (if the client
renders ahead).  So, is the client ahead?  If I need to pre-simulate the
tempent forward, how far forward should I simulate it?

I've been thinking about this as a way of reducing that
blood-splatter-emerges-from-somewhere-behind-the-player effect that you see
with hitscan weapons.

[hlcoders] Jerky Movement when player is on moving lift/elevator.

2006-06-27 Thread Spencer 'voogru' MacDonald

This is a multi-part message in MIME format.

[ Picked text/plain from multipart/alternative ]
Hello,



There is apparently a bug with the SDK, that when you are on say, a lift or
an elevator, your movement becomes jerky when the lift is in motion.
At first I thought it was a problem with some custom movement code, so I got
the base SDK and tried the same map with a lift.



But no dice, same weird jerky movement issue.



So, I fired up HL2DM, same map with a lift, smooth as a babies bottom, I
then got the base HL2DM code, tried it, same jerky movement,

and then CS:S, same jerky movement.



So it appears that valve has applied some fixes to the HL2DM code, which I
have missed out on. Does anyone know how to fix this jerky movement?



Thanks.

I'm not sure if it's the issue or not, but I remember a bug like this in
episode 1.  If it's the same issue, then setting smoothstairs to zero
will fix it (but cause other problems).  If that's the case then you
need to add some logic to disable stair smoothing when the player is on
an elevator.

Here's the code from ep1
baseplayer_shared.cpp:

static ConVar smoothstairs( smoothstairs, 1, FCVAR_REPLICATED,
Smooth player eye z coordinate when traversing stairs. );

//--

void CBasePlayer::SmoothViewOnStairs( Vector eyeOrigin )
{
CBaseEntity *pGroundEntity = GetGroundEntity();
float flCurrentPlayerZ = GetLocalOrigin().z;
float flCurrentPlayerViewOffsetZ = GetViewOffset().z;

// Smooth out stair step ups
// NOTE: Don't want to do this when the ground entity is moving
the player
if ( ( pGroundEntity != NULL  pGroundEntity-GetMoveType() ==
MOVETYPE_NONE )  ( flCurrentPlayerZ != m_flOldPlayerZ ) 
smoothstairs.GetBool() 
 m_flOldPlayerViewOffsetZ == flCurrentPlayerViewOffsetZ

{
int dir = ( flCurrentPlayerZ  m_flOldPlayerZ ) ? 1 :
-1;

float steptime = gpGlobals-frametime;
if (steptime  0)
{
steptime = 0;
}

m_flOldPlayerZ += steptime * 150 * dir;

const float stepSize = 18.0f;

if ( dir  0 )
{

{
m_flOldPlayerZ = flCurrentPlayerZ;
}
if (flCurrentPlayerZ - m_flOldPlayerZ 
stepSize)

m_flOldPlayerZ = flCurrentPlayerZ -
stepSize;

When you say, In hl2dm, it's smooth regardless of the smoothstairs
setting. It sounds like you misunderstand what I'm trying to say.

HL2DM is running the code from episode 1 that I pasted below.
smoothstairs is already disabled when you're on an elevator in HL2DM -
so testing HL2DM isn't going to prove whether this change is the fix or
not - you have to test a mod based on the current SDK code release.

I just did a test on an elevator in Dystopia using smoothstairs 0,
unfortunately the problem still persists.

I noticed when this jerking is taking place there's prediction errors,
further investigation shows it's getting a pred error in
C_BaseEntity::m_vecNetworkOrigin, so I've been looking through the
movement code for answers, to no avail.

so testing HL2DM isn't going to prove whether this change is the fix or
not - you have to test a mod based on the current SDK code release.

 That only masks the problem apparently. In hl2dm, it's smooth
 regardless of the smoothstairs setting.

 I'm not sure if it's the issue or not, but I remember a bug
 like this in episode 1.  If it's the same issue, then setting
 smoothstairs to zero will fix it (but cause other problems).
 If that's the case then you need to add some logic to disable
 stair smoothing when the player is on an elevator.

 Here's the code from ep1
 baseplayer_shared.cpp:

 static ConVar smoothstairs( smoothstairs, 1,
 FCVAR_REPLICATED, Smooth player eye z coordinate when
 traversing stairs. );

 //
 --
 ---
 // Handle view smoothing when going up or down stairs
 //
 --
 ---
 void CBasePlayer::SmoothViewOnStairs( Vector eyeOrigin ) {
   CBaseEntity *pGroundEntity = GetGroundEntity();
   float flCurrentPlayerZ = GetLocalOrigin().z;
   float flCurrentPlayerViewOffsetZ = GetViewOffset().z;

   // Smooth out stair step ups
   // NOTE: Don't want to do this when the ground entity
 is moving the player
   if ( ( pGroundEntity != NULL 
 pGroundEntity-GetMoveType() == MOVETYPE_NONE )  (
 flCurrentPlayerZ != m_flOldPlayerZ ) 
 smoothstairs.GetBool() 
m_flOldPlayerViewOffsetZ == flCurrentPlayerViewOffsetZ
 )
   {
   int dir = ( flCurrentPlayerZ  m_flOldPlayerZ ) ? 1 :
 -1;

   float steptime = gpGlobals-frametime;
   if (steptime  0)
   {
   steptime = 0;
   }

   m_flOldPlayerZ += steptime * 150 * dir;

   const float stepSize = 18.0f;

   if ( dir  0 )
   {
   if (m_flOldPlayerZ  flCurrentPlayerZ)
   {
   m_flOldPlayerZ = flCurrentPlayerZ;
   }
   if (flCurrentPlayerZ - m_flOldPlayerZ 
 stepSize)
   {
   m_flOldPlayerZ = flCurrentPlayerZ -
 stepSize;
   }
   }
   else
   {
   if (m_flOldPlayerZ  flCurrentPlayerZ)
   {
   m_flOldPlayerZ = flCurrentPlayerZ;
   }
   if (flCurrentPlayerZ - m_flOldPlayerZ 
 -stepSize)
   {
   m_flOldPlayerZ = flCurrentPlayerZ +
 stepSize;
   }
   }

   eyeOrigin[2] += m_flOldPlayerZ - flCurrentPlayerZ;
   }
   else
   {
   m_flOldPlayerZ = flCurrentPlayerZ;
   m_flOldPlayerViewOffsetZ = flCurrentPlayerViewOffsetZ;
   }

   [ Picked text/plain from multipart/alternative ] Hello,
  
  
  
   There is apparently a bug with the SDK, that when you are
  on say, a lift or
   an elevator, your movement becomes jerky when the lift is
 in motion.
   At first I thought it was a problem with some custom
  movement code, so I got
   the base SDK and tried the same map with

[hlcoders] Adding sv_showimpacts to HL2DM mod.

2006-06-27 Thread Jed


Is there any simple(ish) way to add sv_showimpacts (as found in CS:S)
to a third party HL2DM  mod or something similar?

We're currently trying to debug a lag/prediction problem and having
this would be very handy.

2006-06-27 Thread Spencer 'voogru' MacDonald

Ah, my mistake.

I see what you meant, I put in your code and it seems to solve a majority of
the problem.

Though, for some reason it still 'feels' different than from HL2DM, the lift
in HL2DM is much smoother still.

I have applied the fix to the Base SDK code to isolate anything we might
have changed with the movement code that could be affecting it.

The easiest way for me to describe it, within HL2DM, if you pay close
attention to the lift, the lift will not appear to jitter up and down.

In the base SDK with the fix, the lift appears to jitters up and down very
slightly. Are there any other optimizations/fixes that have been applied?

Thanks.

- voogru.

Well I have a solution to these issues, Valve should release the code
updates.
Our rotting code becomes more unstable each engine update it seems.
