Jan,
I wrote code to attach models to the play as part of the Ham and Jam mod.
We use it to put random helmet models on the players as a means of trying
to not make them all look the same. I use bone merging as the general
method rather than attachments but it seems to work fine for me.
I'm afraid I haven't opened Visual Studio for over a year but the basics
are thus.
Set-up your player models and create the bones where you want your models
to be attached. You need to then define them as used for bone merging with
the $bonemerge directive in your QC file.
In the models you want to attach to the player, you need to have a bone in
the model with the same name as the bone you will attach to. The general
technique I used is to place the actual prop model on the player model so
it's how you want it to appear on the player model and then create a new
bone in the same position and orientation and the bone I will attach too,
call it something different and weight the attachment model to the new
bone. I then move the new bone and the model down so that it's origin is
0,0,0 and export the SMD. In the QC file I use $renamebone to rename the
extra bone to the same as the bone it will attach to.
So, at this point you should have a player model with named and defined
attachment bones and models you will attach to it with named bones that
match the attachment points.
Codewise what I did was this.
I created a new client and server sidee class called C_PlayerHelmet baed on
on C_PhysicsProp:
class C_PlayerHelmet: public C_PhysicsProp
{
typedef C_PhysicsProp BaseClass;
public:
DECLARE_CLIENTCLASS();
C_PlayerHelmet();
~C_PlayerHelmet();
virtual bool ShouldDraw( void );
};
It's only function, ShouldDraw, basically just does checks to see if it
should draw the helmet, based on if we're the local player or not and such.
bool C_PlayerHelmet::ShouldDraw( void )
{
// TODO: This needs some refinement...
// if we don't have an owner entity...
if ( !GetOwnerEntity() )
return BaseClass::ShouldDraw();
if( GetOwnerEntity() == C_HajPlayer::GetLocalHajPlayer() )
return input->CAM_IsThirdPerson();
}
On the server side I have the same class with basically a Spawn function
which calls PreCache and then BaseClass::Spawn();
That's it - that just the entity to handle the helmet model for the player.
As for actually getting it onto the player model. Well I have a whole bunch
of player class functions to handle that but basically in my player model
class I create an instance for the helmet as:
CHandle<CBaseEntity> m_hHelmetEnt
When I actually want to attach a helmet to the player:
// create the helmet entity
if ( !m_hHelmetEnt )
{
m_hHelmetEnt = (CBaseEntity*)CreateEntityByName( "player_helmet" );
// failure!
if ( !m_hHelmetEnt )
{
DevMsg(1, "Could not create player helmet entity!");
m_bHasHelmet = false;
return;
}
// get the helmet index
unsigned int n = ChooseHelmet();
if ( n > HELMET_NONE )
{
m_hHelmetEnt->SetOwnerEntity( this );
m_hHelmetEnt->SetModel( g_pszHelmetModels[n] );
// must spawn before attaching.
m_hHelmetEnt->Spawn();
m_hHelmetEnt->FollowEntity( this, true );
m_hHelmetEnt->AddEffects( EF_BONEMERGE_FASTCULL );
m_hHelmetEnt->AddEffects( EF_PARENT_ANIMATES );
m_hHelmetEnt->RemoveEFlags( EFL_USE_PARTITION_WHEN_NOT_SOLID );
SetHelmet( n );
m_bHasHelmet = true;
}
}
To take the helmet off:
if ( m_hHelmetEnt )
{
UTIL_RemoveImmediate( m_hHelmetEnt );
m_hHelmetEnt = NULL;
}
That's pretty much the basics. What it does is short is create the
attachment model as it's own entity and have it bonemerge and follow the
player around.
I had a bunch of other stuff which handles the helmet getting shot or blown
off and just spawning it into the world as a non solid gib that vanishes
after a while.
