Re: [hlcoders] Physics props 90° angle snap issue - (linux?)
For future reference: turns out it *was* the linux build. Source doesn't seem to like gcc 4.2.4 - built fine, but with a few vphysics quirks as said below. I rebuilt with gcc 4.1.2 and the 90° snap issue was gone. Makes me fear though what other kind of bugs are due to the gcc version, and what gcc version finally is the way to go, if there is any :) On 20/02/2011 16:04, Maarten De Meyer wrote: No no, I'm fairly sure it's not me :D I beyond-compare'd anything between prop_physics and the engine, no relevant changes on my side. I still think it'll turn out to be an issue with the linux build - eg gcc version can be a factor too, although we're on 4.2.4 so we should be good. If I end up not finding it at all I'll compile a clean OB mod on my linux machine or something and work from there, but hope that won't be necessary.

Re: [hlcoders] Physics Problem
Now, I haven't messed with the physics system, but it sounds like the prop is unaware things have changed. Props in Source that haven't moved for a while, aren't physically simulated, for performance reasons. I would find a way to broadcast an event that tells nearby props that they need to be simulated. (Or hackier: Simply find all nearby props and move them a little or something.) - Sortie. - Original Message - From: Grash mr_gr...@yahoo.com To: Discussion of Half-Life Programming hlcoders@list.valvesoftware.com Sent: Friday, February 20, 2009 10:16 PM Subject: [hlcoders] Physics Problem Here's the setup: I have a prop_physics on top of a func_brush.

Re: [hlcoders] Physics Problem
When the object is disabled it isn't forcing a physics update on physics props touching it. You just need to force a physics update on those props on disable. I am pretty sure the code to do this can be found in the func_breakable as I believe when those break the physics objects update accordingly. Cheers.

[hlcoders] physics shadow?
Can someone explain this one to me? In VPhysicsShadowUpdate() I just took all the traces ie util_traceline, util_traceentity, etc and changed the MASK_PLAYERSOLID to use PhysicsSolidMaskForEntity() except I used some ifdefs so I remember that the code was modified by our mod when it comes time to merge new code that affected this file for instance.

Re: [hlcoders] physics shadow?
The physics shadows are basically a physics object that follows an entity that doesn't move with vphysics, ie: an npc, or the player, and provides collision with physics objects, and has callbacks to notify the entity it's following that it just collided with something else that is vphysics (or another shadow) -Tony -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Chang Sent: October-02-08 11:59 PM To: hlcoders@list.valvesoftware.com Subject: [hlcoders] physics shadow?

Our recently released modification (Fistful of Frags) is suffering some
stability issues. Hope someone can bring some light to these serious servers
crashes. I posted another similar issue in this list, and as I said before, I
never modified any part of the physics code. Now I'm starting to understand
what's going on, seems like a physic entity was removed, but server is still
trying to use it so finds a null pointer and crashes. Is that rigth?
These issues were noticed only during maximum stress, once the mod was
released. They may happen rarely or not, depends the way physics are stressed I
guess.
I'm using UTIL_Remove in several parts of the game, example: a cowboy hat is
created (falls to ground), and after some seconds is deleted. There are other
items deleted in a similar way. Should I use other method different from
UTIL_Remove?
And a last question. Can server performance ( low FPS) make these issues worse?
Because they tend to happen more in our own server, which sometimes is even
below 10 FPS.
Hope this helps, these are 3 different call stacks we are seeing repitedly. If
you need any other info plz let me know.

RE: [hlcoders] Physics crash related (urgent).
Are you deleting the entities inside a callback form vphysics? e.g.
VPhysicsCollision? That can cause crashes. There should be code that
prevents that - i.e. UTIL_Remove() should actually add the object to a
list by calling PhysCallbackRemove() but I don't have the SDK code in
front of me so I can't check.

[hlcoders] Physics crash related (urgent).
All of our buildable objects - detpack, dispenser, sg - run the code below
when they explode. The detpack is a real physics object (as in it uses
VPhysicsInitNormal()) and I'm assuming your hat you describe is vphysics as
well.
void CFFBuildableObject::Explode( void )
{
VPROF_BUDGET( CFFBuildableObject::Explode,
VPROF_BUDGETGROUP_FF_BUILDABLE );
// MUST DO THIS or CreateExplosion crashes HL2
m_takedamage = DAMAGE_NO;
// Remove bounding box (other models follow this pattern...)
SetSolid( SOLID_NONE );
// Do the explosion
DoExplosion();
// Notify player to tell them they can build
// again and remove current owner
m_hOwner = NULL;
// Remove entity from game
UTIL_Remove( this );
}
And that's it. There's also a method for 'quietly' removing a buildable
object (like when dismantling) but it's the same code minus the
DoExplosion() call.
Anyway, we've never experienced/received minidumps from people w/ weird
physics related errors so perhaps you need some other steps in addition to
using UTIL_Remove().

crashes. I posted another similar issue in this list, and as I said
before,
I never modified any part of the physics code. Now I'm starting to
understand what's going on, seems like a physic entity was removed, but
server is still trying to use it so finds a null pointer and crashes. Is
that rigth?
These issues were noticed only during maximum stress, once the mod was
released. They may happen rarely or not, depends the way physics are
stressed I guess.
I'm using UTIL_Remove in several parts of the game, example: a cowboy hat
is
created (falls to ground), and after some seconds is deleted. There are
other items deleted in a similar way. Should I use other method different
from UTIL_Remove?
And a last question. Can server performance ( low FPS) make these issues
worse? Because they tend to happen more in our own server, which sometimes
is even below 10 FPS.
Hope this helps, these are 3 different call stacks we are seeing
repitedly.
If you need any other info plz let me know.

void CFFBuildableObject::Explode( void )

UTIL_Remove( this );
}
And that's it. There's also a method for 'quietly' removing a buildable
object (like when dismantling) but it's the same code minus the
DoExplosion() call.
Anyway, we've never experienced/received minidumps from people w/ weird
physics related errors so perhaps you need some other steps in
addition to
using UTIL_Remove().

The decompiler is not setup for this model version. The fact that it even works at all is great.

RE: [hlcoders] Physics on live npcs?!
Yeah - we call that jiggle bones - there's a little simulator you can
configure in your qc with the orange box engine. It's something one of
the Turtle Rock guys developed for CS:S or L4D. You can see the
simulation in hlmv. I don't know if there is a doc for them yet, but
here's the qc from the antlion worker for example:
//
// jiggle bones for antlion worker
//
$jigglebone Antlion.AntR_bone {
is_flexible {
yaw_stiffness 700
yaw_damping 8
// yaw_constraint 30 -30
pitch_stiffness 700
pitch_damping 8
// pitch_constraint 30 -30
tip_mass 10
length 5
angle_constraint 20
}
}
$jigglebone Antlion.AntL_bone {
is_flexible {
yaw_stiffness 700
yaw_damping 7
// yaw_constraint 30 -30
pitch_stiffness 700
pitch_damping 8
// pitch_constraint 30 -30
tip_mass 15
length 5
angle_constraint 20
}
}
$jigglebone Antlion.glasswingR_bone {
is_flexible {
yaw_stiffness 700
yaw_damping 6
// yaw_constraint 30 -30
pitch_stiffness 700
pitch_damping 8
// pitch_constraint 30 -30
tip_mass 5
length 30
angle_constraint 37
}
}
$jigglebone Antlion.glasswingL_bone {
is_flexible {
yaw_stiffness 700
yaw_damping 5
// yaw_constraint 30 -30
pitch_stiffness 700
pitch_damping 8
// pitch_constraint 30 -30
tip_mass 5
length 30
angle_constraint 40
}
}

[hlcoders] Physics bounce sounds
Hi list, this is probably an easy question. Im grinding through our buglist and one of them is that our grenades do not have a bounce sound. I checked the code and there's an empty BounceSound function that is deliberately left empty since physics supposedly handles bounce sounds. I can add an EmitSound in the BounceSound function which does give me a bounce sound, but I'd much rather have surface-dependent bounce sounds than one hard-coded one. Any idea why these are not triggered when the (otherwise default SDK) grenade hits surfaces?

RE: [hlcoders] Physics bounce sounds
The sound is triggered by CBaseEntity's implementation of VPhysicsCollision(). If you've overridden that function in your leaf class without chaining to the base class you'd lose physics sound/dust/etc effects. So that's one possible cause. Otherwise set a breakpoint there (or in the caller: PostCollision - src/dlls/physics.cpp) and step through the call when the grenade bounces to see why no sound is played.

[hlcoders] physics validation
-- [ Picked text/plain from multipart/alternative ] Hi all, Our mod is a tool for teachers to create event-driven games for their students. We need to evaluate the Source physics engine to determine if teachers can create physics problems with their games (i.e. there is an object with x mass, apply y force vector to that object, it will go z distance). Has anyone done tests to evaluate how closely the physics engine emulates real life? Also, the gravity constant is set for either 600 or 800 in/s^2.

RE: [hlcoders] physics validation
Gravity is intentionally exaggerated in our games. Real-world gravity is ~386 in/sec^2. There are many factors which appear to affect the user perception of gravity relative to the rest of the game's presentation. I'd love to see some kind of research on this topic but I've yet to find any. Based on the testing we've done with our games we've found that exaggerated gravity is necessary - real world gravity makes objects in the game appear too light and/or too slow. Also note that we have a simple simulation of air resistance in our games. If you're trying to make a simulation using Source match up with a specific set of calculations you'll want to include air resistance or disable our simulator (set the air density to zero). The engine is doing a rigid body simulation that can be configured to be reasonably close to reality for objects that behavior like ideal rigid bodies.

[hlcoders] Physics becoming out of sync
-- [ Picked text/plain from multipart/alternative ] So I'm doing bots for Fortress Forever and I have run into a problem that appears to be a bug with the game. The odd thing is that I can't reproduce it myself as a player, and so far have only observed it happen to the bot players. There is a func_door being used as a lift, and when someone gets under the lift, when it comes down and hits the player it will go back up. The problem is that when the bot gets underneath just once, the lift is stuck in a perpetual up and down oscillation. After some debugging it became clears that the problem was physics related, since the physics system was calling CCollisionEvent::AddTouchEvent every time the lift came down, even though the bot had already ran off and was nowhere near the lift. I added some debug drawing stuff in the function CCollisionEvent::AddTouchEvent, to draw the bounds of the collidable, like so: debugoverlay-AddBoxOverlay( pEntity0-GetCollideable()-GetCollisionOrigin(), pEntity0-GetCollideable()-OBBMins(), pEntity0-GetCollideable()-OBBMaxs(), pEntity0-GetCollideable()-GetCollisionAngles(), 255, 0, 255, 0, 10.0f); debugoverlay-AddBoxOverlay( pEntity1-GetCollideable()-GetCollisionOrigin(), pEntity1-GetCollideable()-OBBMins(), pEntity1-GetCollideable()-OBBMaxs(), pEntity1-GetCollideable()-GetCollisionAngles(), 255, 0, 255, 0, 10.0f); Here is a picture of that. http://i8.tinypic.com/258z4zk.jpg As you can see, the collidables bounding boxes at least are where they should be, and not touching. The small red lines under the lift are the collision position and collision normal also passed to the function, so there is clearly something being registered as hitting. After digging around for more stuff I came across the cvar physicsshadowupdate_render, and when enabled finally showed the problem. http://i7.tinypic.com/258z5u8.jpg The rendering for these boxes is in CBasePlayer::VPhysicsShadowUpdate. The blue box is the players IPhysicsObject-GetPosition(), the red box is at the GetAbsOrigin() of the character. Clearly they are out of sync. These boxes should be pretty much together, but for some reason they aren't. I noticed the comment at the bottom of the function that reads // UNDONE: Force physics object to be at player position when not touching phys??? Why was this undone? Anyone know what part of the code is responsible for keeping the physics synced with the entity and vice versa? Stepping through the code in CBasePlayer::VPhysicsShadowUpdate How could these get out of sync like this? I haven't been able to reproduce this as a player, only happens to the bot so far, but I can't see any reason at all that it would be bot related. We aren't messing with the physics for the bot in any way. This is really annoying. Any feedback is appreciated.

Re: [hlcoders] Physics becoming out of sync

[ Picked text/plain from multipart/alternative ]
I think the bot's physics object has fallen asleep. If you look at the call
stack for VPhysicsShadowUpdate its called like this in physics.cppPhysFrame:
// apply updates
if ( pPhysics !pPhysics-IsAsleep() )
{
pEntity-VPhysicsShadowUpdate( pPhysics );
}
Stepping through PhysFrame shows that the SDK bots have a valid physics
object but that its asleep. This would also explain why SDK bots are hard to
hit with combine balls, as the combine ball does its damage/dissolve effect
in VPhysicsCollision, which wouldn't happen correctly if the bots vphysics
shadow is not being updated because its fallen asleep and is lingering
somewhere else on the map.
Anyways, we just need to find why the bots physics object is sleeping on the
job and it would be fine. A really bad way to test if this would fix your
problem is to just replace the if statement in PhysFrame with
// apply updates
if ( pPhysics (!pPhysics-IsAsleep() || pEntity-IsPlayer()) )
{
pEntity-VPhysicsShadowUpdate( pPhysics );
}
If that fixes your bots physics shadow then at least you know you just need
to figure out why its falling asleep. I'll keep looking for an answer there
as well.

Paul

Re: [hlcoders] Physics becoming out of sync
-- [ Picked text/plain from multipart/alternative ] Okay, seems like the problem is in CBasePlayer::PhysicsSimulate, where the UpdateVPhysicsPosition is not being called for bots. PhysicsSimulate is the main place where UpdateVPhysicsPosition is called. There's also a wrapper for UpdateVPhysicsPosition called UpdatePhsyicsShadowToCurrentPosition that is called sometimes, for example when being pushed by your lift! So basically what's happening is that PhysicsSimulate is not updating physics shadow for every game frame, but some touch events are calling a function that moves the shadow into place. Whenever the shadow moves, it wakes up, but when its idle for too long (because PhysicsSimulate isnt updating it) it falls asleep. One way to fix this would be to override PhysicsSimulate in the bot's entity class and make sure that UpdateVPhsyicsPosition is called (just hack up the PhysicsSimulate from CBasePlayer so that it calls it under the right circumstances for your bots instead of actual players) I hope this helps.

Re: [hlcoders] Physics becoming out of sync
-- [ Picked text/plain from multipart/alternative ] Thanks the help. Are you having the same problem with your bots or just going out of your way to be helpful? Either way I appreciate it. On further investigation, it appears the problem is due to the bots user commands going through a different code path. AFAIK, we're supposed to be calling RunPlayerMove(cmd); and PostClientMessagesSent(); on the bot controller for the bot. This works fine and all, but it bypasses the codepath that the players usercommand takes, which is CBasePlayer::ProcessUsercmds Since CBasePlayer::ProcessUsercmds doesn't get called for bots, AllocCommandContext() doesn't get called for bots, and therefor why int command_context_count = GetCommandContextCount(); is always 0 for bots(in CBasePlayer::PhysicsSimulate), and its within that loop that UpdateVPhysicsPosition is called. Are there any special considerations to UpdateVPhysicsPosition being called? Or can I safely call it every frame at the end of the bot block in CPlayerInfo::RunPlayerMove. Think, first I'll see what happens if I call ProcessUsercmds on the bot player directly. Calling UpdateVPhysics on my own feels like a dirty hack. I'm hesitant about doing stuff like just calling the function directly. IMO that's masking the symptoms of a potentially bigger problem. It looks like this is another problem that needs addressing if Valve gets around to fixing the broken bot support, as that is the only way to feed user commands from server plugins.

Re: [hlcoders] Physics becoming out of sync
-- [ Picked text/plain from multipart/alternative ] Ok, so I tried ProcessUsercmds(cmd, 1, 1, 0, false); in place of IBotController::RunPlayerMove(cmd); It fixed the lift bug it seems but broke the view angles, and the bot kept facing his spawn direction or something. That's probably not too hard to fix, but after that I also tried m_pParent-UpdatePhysicsShadowToCurrentPosition(); in CPlayerInfo::RunPlayerMove and kept my previous user command method of IBotController::RunPlayerMove(cmd); This way he could move normally, but the lift bug wasn't fixed. I don't know what m_pPhysicsController-Update is doing in CBasePlayer::UpdateVPhysicsPosition, but apparently it isn't updating the physics position. Can't tell yet if theres an order of operation I'm missing. I guess after work I'll change it back to ProcessUsercmds method and figure out why their view angles are busted. Probably less work than trying to debug this broken bot command codepath. If theres anyone at valve who has any input or a possible 'right' solution to fixing the issue please let me know. I hate to deviate too far from the functionality that is also usable in server plugins, as I still hold out hope of that stuff being fixed in a future sdk update.

Re: [hlcoders] Physics becoming out of sync
-- [ Picked text/plain from multipart/alternative ] Is there anything that would mess that up? I tried calling UpdatePhysicsShadowToCurrentPosition(), which calls UpdateVPhysicsPosition( GetAbsOrigin(), vec3_origin, gpGlobals-frametime ); but it didn't fix the problem. The blue box shown in the above linked screenshots remained stuck under the lift. The blue box is drawn at the location IPhysicsObject::GetPosition(), while the other is drawn at the players GetAbsOrigin(). It would seem that the calling of UpdateVPhysicsPosition( GetAbsOrigin(), vec3_origin, gpGlobals-frametime ); above would bring this physics object in sync with the entity, but it doesn't seem to. Is there a specific time that function should be called? I tried calling it right after the processing of the bots user command in CPlayerInfo::RunPlayerMove( CBotCmd *ucmd ) so far. I'm tempted to call m_pParent-VPhysicsGetObject()-SetPosition( GetAbsOrigin(), vec3_angle, true ); in there as well, but I don't want to cause any additional problems. Any ideas?

Are you having the same problem with your bots or just going out of your way to be helpful? Either way I appreciate it. On further investigation, it appears the problem is due to the bots user commands going through a different code path. AFAIK, we're supposed to be calling RunPlayerMove(cmd); and PostClientMessagesSent(); on the bot controller for the bot. This works fine and all, but it bypasses the codepath that the players usercommand takes, which is CBasePlayer::ProcessUsercmds Since CBasePlayer::ProcessUsercmds doesn't get called for bots, AllocCommandContext() doesn't get called for bots, and therefor why int command_context_count = GetCommandContextCount(); is always 0 for bots(in CBasePlayer::PhysicsSimulate), and its within that loop that UpdateVPhysicsPosition is called. Are there any special considerations to UpdateVPhysicsPosition being called? Or can I safely call it every frame at the end of the bot block in CPlayerInfo::RunPlayerMove. Think, first I'll see what happens if I call ProcessUsercmds on the bot player directly. Calling UpdateVPhysics on my own feels like a dirty hack. I'm hesitant about doing stuff like just calling the function directly. IMO that's masking the symptoms of a potentially bigger problem. It looks like this is another problem that needs addressing if Valve gets around to fixing the broken bot support, as that is the only way to feed user commands from server plugins.

PhysicsSimulate is the main place where UpdateVPhysicsPosition is called. There's also a wrapper for UpdateVPhysicsPosition called UpdatePhsyicsShadowToCurrentPosition that is called sometimes, for example when being pushed by your lift! So basically what's happening is that PhysicsSimulate is not updating physics shadow for every game frame, but some touch events are calling a function that moves the shadow into place. Whenever the shadow moves, it wakes up, but when its idle for too long (because PhysicsSimulate isnt updating it) it falls asleep.

UpdateVPhysicsPosition( m_vNewVPhysicsPosition,

[hlcoders] Physics Problem
I have a physics object that I'm trying to retrieve its angular velocity in degrees/second. Using GetVelocity(Vector * velocity, AngularImpulse * angularVelocity), it appears that I can retrieve the angular impulse of the angular velocity. Getting this value, I multiply it by 180*pi to convert from radian to degrees, and then I divide by the object's mass. However, I compare this to the actual change in degrees that the model undergoes, and the values are different. For example, if I use SetVelocity(...) to input an AngularImpulse of 100 for the x axis/pitch every frame, then convert to radians and divide by a mass of 2080, I get approximately 2.8. However, if I sample the actual change in degrees of the object's pitch every frame, it comes out to approximately 19 degrees/second. What am I doing wrong, and how can I correctly calculate an object's change in angle in degrees/sec? ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders

[hlcoders] Physics and Melee weapons
I'm currently writing a melee weapon system for the mod I'm working on. It's going to work rather differently to way say the HL2 crowbar works in that instead of just whacking buttons to make your character do different attacks the movements of your mouse will determine how you attack. I've setup a system whereby the mouse is tracked client side and when an attack is made the information about what kind of attack it is is sent over to the server via a client-command (i.e. if it was a slash attack for a sword it'd send over a number identifying the attack and two other numbers giving the direction the mouse was moved in). I then use pose parameters to control the attack animation (so for example you can slash a sword in any direction you want). The difficulty I'm having is in actually creating the weapon that will sit in the players hand and collide with things / effect physics objects etc. Currently I've coded a base melee weapon class (inherited from CBaseEntity not CBaseCombatWeapon) and I'm using bone followers to get a physics shadow which follows the weapon model. The weapon model follows the player's hand movement using the same method weapons inherited from CBaseCombatWeapon do (i.e. using the CBaseEntity::FollowEntity function which sets up a bone merge). Thus when the player makes an attack, the player model animation moves the weapon model and if it hits stuff the appropiate action can occur (i.e. if it hits a player damage calculations can be done, if it hits a physics object it could knock it over etc). However when I use a bone follower to create a physics shadow which follows round the weapon model I'm told the server is stuck on the sword model the player is carrying and hence the player model can't really move anywhere. If I stand next to a physics object and equip the sword I can knock over the object so it works in one respect. Does anyone know what would be cause the server to be getting stuck on the sword model and how I could fix this? Also is this the best way to do what I want (namely I'm using a bone follower which creates a physics shadow, to follow round a model bone merged to a players hand so the model can interact with physics objects etc)? I'm not particular familiar with Source's physics system yet so I could be going completely the wrong way about this. ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
