[hlcoders] Client-Side entities questions
1) Creating solid client-side entities
I'm working on a mod that involves building structures on the ground from a
"RTS" view (topdown), using the mouse cursor. To help the player position
its structure, I'm creating a temporary client-side entity reprensiting the
selected structure. This temporary entity follows the mouse cursor to help
him visualize where the structure will be placed.
I've managed to create the client side only entity using
C_BaseEntity::InitializeAsClientEntity(,
RENDER_GROUP_OPAQUE_ENTITY). I've also added the following code in the temp
model entity's SpawnClientEntity method:
MyTempModelClass::SpawnClientEntity( void )
{
SetMoveType(MOVETYPE_NONE);
SetSolid( SOLID_BBOX );
}
The real problem arise when I try to access the temp model entity's
collision bounds. Basically, I want to get the current model's mins & maxs
and use them in a UTIL_TraceHull to check if the location where the player
wants to build is free or not (ie: there is a player or another structure
there already). Ive tryed several different ways of accessing these mins &
maxs (WorldAlignedMins/Maxs(), PropCollision()->OBBMins/Maxs(),
GetRenderBounds, etc) but each time the returned vectors are (0,0,0) for
some reasons. Also, the client-side structure doesn't appear to be solid (I
can walk through it) but this may be because collision detections are done
server side in this case.
I have no idea what Im doing wrong here and could really use some help on
this matter. Is there a better way of checking if a given space around an
entity is empty of solid entities / world geometry?
2) Entity Visibility on the client-side
I would like to determine if a given set of C_BaseEntities are currently
visible to the local player on the client side, without using expensive
trace lines. I'm going to be displaying text on the hud near each of these
entities, and I would like to cull out the ones that are not currently
visible. I've tryed using g_pClientLeafSystem->IsRenderableInPVS(
) but it doesn't seem to have any effect as I can
still see the name of entities behind walls appearing through.
Thanks in advance for your help!

[hlcoders] VGUI and Schemes... (Again.)
Well I'd left this hanging for a while because i had a ton of other
things to do for my mod, but i'm back at square "VGUI" trying to figure
out how to make my panels be scheme'd based on the localplayer's team.
I already have a function that returns the correct names of schemes
based on his team... BUT, for some reason, there just isn't a way for it
to use anything else but ClientScheme.
Here's some example code i tried to use in a CONSTRUCTOR for my panel,
and it wasn't able to fetch the right scheme (the colors were still the
default HL2 ones.)
vgui::HScheme myscheme;
myscheme =
vgui::scheme()->LoadSchemeFromFile("resource/VaminScheme.res","VaminScheme");
SetScheme(myscheme);
InvalidateLayout(false,true);
It doesn't work.
I tried FORCING my own scheme down the throat of ApplySchemeSettings and
same result: default scheme...
You can't tell me nothing is wrong here, i don't think i've overlooked
anything to get this dumb custom scheme to work, something is borked and
i doubt it's on my end :(

Re: [hlcoders] Netcode and Vehicles

I did this using an #ifdef CLIENT_DLL like is shown many times in the code. #include "cbase.h" #ifdef CLIENT_DLL #include "c_prop_vehicle.h" #include "c_baseplayer.h" #define CPropCGjeep C_PropCGjeep #define CPropVehicleDriveable C_PropVehicleDriveable #else #include "vehicle_base.h" #include "baseplayer.h" #endif #include "movevars_shared.h" #include "view.h" #include "flashlighteffect.h" #include "c_te_effect_dispatch.h" #include "CBaseVehicles.h" However, when I declare this: IMPLEMENT_NETWORKCLASS_ALIASED( CPropCGjeep, DT_PropCGjeep ) The compiler gives me the error: error C2653: 'C_CPropCGjeep' : is not a class or namespace name Why would the preprocessor be inserting that extra C when I clarly have CPropCGJeep being changed to C_PropCGjeep? Also, am I going about this the right way? Will I be able to derive that shared class from 2 completely different classes (CPropVehicleDriveable, C_PropVehicleDriveable) and still have it 'sync' up?

I'm not going to bother looking into it particularly deeply (:P) but keep in mind that IMPLEMENT_NETWORKCLASS_ALIASED is a macro.

Re: [hlcoders] Shared-Jeep-Code Thread
Childe Roland wrote: I basically tried to create one class that contains all the functions of both the PropVehicleJeep and C_PropVehicleJeep. When I compile it, I still get one error. All of this is just from grepping the the source code. I haven't actually worked with any of this so I might be talking out of my ass (a neat trick), but here goes... Probably the best thing to do is take one entity and look at what it has defined, for example basegrenade_shared.cpp has this... #if !defined( CLIENT_DLL ) // Global Savedata for friction modifier BEGIN_DATADESC( CBaseGrenade ) // nextGrenade DEFINE_FIELD( m_hThrower, FIELD_EHANDLE ), // m_fRegisteredSound ??? DEFINE_FIELD( m_bIsLive, FIELD_BOOLEAN ), DEFINE_FIELD( m_DmgRadius, FIELD_FLOAT ), DEFINE_FIELD( m_flDetonateTime, FIELD_TIME ), DEFINE_FIELD( m_flWarnAITime, FIELD_TIME ), DEFINE_FIELD( m_flDamage, FIELD_FLOAT ), DEFINE_FIELD( m_iszBounceSound, FIELD_STRING ), DEFINE_FIELD( m_bHasWarnedAI, FIELD_BOOLEAN ), // Function Pointers DEFINE_THINKFUNC( Smoke ), DEFINE_ENTITYFUNC( BounceTouch ), DEFINE_ENTITYFUNC( SlideTouch ), DEFINE_ENTITYFUNC( ExplodeTouch ), DEFINE_USEFUNC( DetonateUse ), DEFINE_THINKFUNC( DangerSoundThink ), DEFINE_THINKFUNC( PreDetonate ), DEFINE_THINKFUNC( Detonate ), DEFINE_THINKFUNC( TumbleThink ), END_DATADESC() void SendProxy_CropFlagsToPlayerFlagBitsLength( const SendProp *pProp, const void *pStruct, const void *pVarData, DVariant *pOut, int iElement, int objectID); #endif ...BEGIN_DATADESC (found in datamap.h) defines the GetDataDescMap() function for you. The DATADESC stuff, to me, just looks like stuff you would need to save/restore for a single player game. I would assume for a multiplayer game, you could just have something like this... BEGIN_DATADESC( CBaseGrenade ) // empty END_DATADESC() ...then back to basegrenade_shared.cpp we have this... IMPLEMENT_NETWORKCLASS_ALIASED( BaseGrenade, DT_BaseGrenade ) BEGIN_NETWORK_TABLE( CBaseGrenade, DT_BaseGrenade ) #if !defined( CLIENT_DLL ) SendPropFloat( SENDINFO( m_flDamage ), 10, SPROP_ROUNDDOWN, 0.0, 256.0f ), SendPropFloat( SENDINFO( m_DmgRadius ), 10, SPROP_ROUNDDOWN, 0.0, 1024.0f ), SendPropInt( SENDINFO( m_bIsLive ), 1, SPROP_UNSIGNED ), // SendPropTime( SENDINFO( m_flDetonateTime ) ), SendPropEHandle( SENDINFO( m_hThrower ) ), SendPropVector( SENDINFO( m_vecVelocity ), 0, SPROP_NOSCALE ), // HACK: Use same flag bits as player for now SendPropInt ( SENDINFO(m_fFlags), PLAYER_FLAG_BITS, SPROP_UNSIGNED, SendProxy_CropFlagsToPlayerFlagBitsLength ), SendPropTime( SENDINFO( m_flNextAttack ) ), #else RecvPropFloat( RECVINFO( m_flDamage ) ), RecvPropFloat( RECVINFO( m_DmgRadius ) ), RecvPropInt( RECVINFO( m_bIsLive ) ), // RecvPropTime( RECVINFO( m_flDetonateTime ) ), RecvPropEHandle( RECVINFO( m_hThrower ) ), // Need velocity from grenades to make animation system work correctly when running RecvPropVector( RECVINFO(m_vecVelocity), 0, RecvProxy_LocalVelocity ), RecvPropInt( RECVINFO( m_fFlags ) ), RecvPropTime( RECVINFO( m_flNextAttack ) ), #endif END_NETWORK_TABLE() ...this defines the networked properties that get sent from server to client. Notice the code compiled on the server would include the SendPropXXX() stuff and the code compiled on the client would include the RecvPropXXX() stuff (and you BETTER have a RecvProp() for each SendProp() or things will get weird). This NETWORK_TABLE lets the engine know what data needs to be replicated between the server and the client. Then we have this... BEGIN_PREDICTION_DATA( CBaseGrenade ) DEFINE_PRED_FIELD( m_hThrower, FIELD_EHANDLE, FTYPEDESC_INSENDTABLE ), DEFINE_PRED_FIELD( m_bIsLive, FIELD_BOOLEAN, FTYPEDESC_INSENDTABLE ), DEFINE_PRED_FIELD( m_DmgRadius, FIELD_BOOLEAN, FTYPEDESC_INSENDTABLE ), // DEFINE_PRED_FIELD_TOL( m_flDetonateTime, FIELD_FLOAT, FTYPEDESC_INSENDTABLE, TD_MSECTOLERANCE ), DEFINE_PRED_FIELD( m_flDamage, FIELD_FLOAT, FTYPEDESC_INSENDTABLE ), DEFINE_PRED_FIELD_TOL( m_vecVelocity, FIELD_VECTOR, FTYPEDESC_INSENDTABLE, 0.5f ), DEFINE_PRED_FIELD_TOL( m_flNextAttack, FIELD_FLOAT, FTYPEDESC_INSENDTABLE, TD_MSECTOLERANCE ), // DEFINE_FIELD( m_fRegisteredSound, FIELD_BOOLEAN ), // DEFINE_FIELD( m_iszBounceSound, FIELD_STRING ), END_PREDICTION_DATA() ...to define prediction data so that things that are moving/changing on the clients and servers can be predicted properly. If you look at the BEGIN_PREDICTION_DATA() macro, you'll notice this part... &BaseClass::m_PredMap ...oh, cool. The Prediction data also includes the prediction data of the base class that this class inh
RE: [hlcoders] VGUI and Schemes... (Again.)
Override Panel::SetScheme() in your panel class (both Hscheme and string
versions), write a simple pass thru and drop a breakpoint on it. I bet
that the view port or something similar is resetting your panels scheme
after construction.
Scheme application is recursive, it applied to all children panels under
the parent. The base viewport is the parent of all the hud panels, so
when it gets it scheme set it will reset all the hud elements to that
scheme.

[hlcoders] Shared-Jeep-Code Thread
I basically tried to create one class that contains all the functions of both the PropVehicleJeep and C_PropVehicleJeep. When I compile it, I still get one error. - CBaseVehicle.obj : error LNK2001: unresolved external symbol "private: virtual struct datamap_t * __thiscall C_CPropCGjeep::GetDataDescMap(void)" ([EMAIL PROTECTED]@@EAEPAUdatamap_t@@XZ) - I can't find any examples of GetDataDescMap, so I assume it is in one of the Macros. This is how I used the Macros: -- IMPLEMENT_NETWORKCLASS_ALIASED( CPropCGjeep, DT_PropCGjeep ) BEGIN_NETWORK_TABLE( CPropCGjeep, DT_PropCGjeep ) END_NETWORK_TABLE() BEGIN_PREDICTION_DATA( CPropCGjeep ) END_PREDICTION_DATA() - Is this correct? Do I need to put my variables inside these macros, or will that be done automatically? I'm still not sure about the useage of the Network macros, perhaps when I get those right, the linker error will be fixed. -- = Childe Roland "I will show you fear in a handful of jellybeans." ___ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
