Getting owner of rpg rocket entity?

hlstriker · **Author**

Would it be possible to get the owner of an RPG Rocket entity with SourceMod yet? If it is, how would I go about doing it?

I'm starting the transfer from AMXX to SM now and could use some help

It's possible if you know the index of the rocket entity in question.

I don't have that yet. Was hoping maybe someone could let me know that too

The way I found a RPG rocket index with AMXX was using FM_SetModel. I tried searching around for a forward like that but found nothing

I'm clueless on how to do this, unless there is something like "find_ent_by_class" for SourceMod that I could search for?

I learn best by seeing others code and picking through it to see what it all does. I've already looked at quite a few plugins but none came close to doing this stuff.

There is the function FindEntityByClassname, but I am not sure what would you look for...

This functions might be also useful for you:

EDIT:
I found this within weapon_rpg.cpp, it might be of your interest

Code:

void CMissile::Precache( void )
{
	PrecacheModel( "models/weapons/w_missile.mdl" );
	PrecacheModel( "models/weapons/w_missile_launch.mdl" );
	PrecacheModel( "models/weapons/w_missile_closed.mdl" );
}

Code:

CMissile *CMissile::Create( const Vector &vecOrigin, const QAngle &vecAngles, edict_t *pentOwner = NULL )
{
	//CMissile *pMissile = (CMissile *)CreateEntityByName("rpg_missile" );
	CMissile *pMissile = (CMissile *) CBaseEntity::Create( "rpg_missile", vecOrigin, vecAngles, CBaseEntity::Instance( pentOwner ) );
	pMissile->SetOwnerEntity( Instance( pentOwner ) );
	pMissile->Spawn();
	pMissile->AddEffects( EF_NOSHADOW );
	
	Vector vecForward;
	AngleVectors( vecAngles, &vecForward );

	pMissile->SetAbsVelocity( vecForward * 300 + Vector( 0,0, 128 ) );

	return pMissile;
}

Code:

DEFINE_FIELD( m_hOwner,					FIELD_EHANDLE ),

Thanks Nican, this should help a lot when I get a few other things figured out first.

I'm working with the mod Fortress-Forever and it controls the map entities with code written in a lua file. You can do all sorts of stuff with these files but it's all map specific. There are a list of 'call backs' the mod uses and was wondering if there is a way to call these with sourcemod. Here is a link to some of them...

Also, I'm still wondering how to get the owner

I have a feeling the way I'm going to have to find the entity is in OnGameFrame() which I hoped to avoid.

EDIT:
I take using OnGameFrame() back. There has to be another method because calling FindEntityByClassname() will be to extreme there.

Try hooking something releated to "+attack," (I think if directly hook +attack won't work) and on every "+attack," seek for the missile 0.2 sec later

I would love a bright between LUA and SM too... I hate lua and VB, they changed everything from the original computer langush

EDIT:
Does anyone know where I can find a TF:Forever offset props list? From there I can show you where to get the owner

Owner is usually in an entity handle property named m_hOwner.

Getting the rocket entity sounds tricky, you will need to find an event or function where it's been created.

Good news, hooking +attack worked!

Now I guess I'll just use that for now with a timer calling a function searching for the rocket (which I'm hoping it's classname is rpg_missile).

Thanks for the help BAIL and Nican

EDIT:
Gah! Got an error I don't want to see...
"FindEntityByClassname" not supported by this mod

Is there a way I can add this myself to the mod?
