Programatically working out how many weapons/turrets a ship has

[Laz]

Hey guys. Inside of FLHook we have the following definition for the ship entry.

	struct IMPORT Ship : EqObj
	{
		Ship(struct Ship const &);
		Ship(struct ICliObj *);
		virtual ~Ship(void);
		struct Ship & operator=(struct Ship const &);
		static int const  MAX_EXHAUST_NOZZLES;
		virtual enum AClassType  get_class_type(void)const;
		std::vector <struct cachestring="">const * get_legal_hps(enum HpAttachmentType)const;
		virtual bool read(class INI_Reader &);
		virtual void redefine(struct Root const &);

	public:
		/* 36 */ uint iDunno12[19];
		/* 55 */ char* szBayDoorAnim;
		/* 56 */ char* szHpBaySurface;
		/* 57 */ char* szHpBayExternal;
		/* 58 */ char* szHpTractorSource;
		/* 59 */ uint	iIDSInfo1;
		/* 60 */ uint	iIDSInfo2;
		/* 61 */ uint	iIDSInfo3;
		/* 62 */ uint	iShipClass;
		/* 63 */ uint	iNumExhaustNozzles;
		/* 64 */ float	fHoldSize;
		/* 65 */ float	fLinearDrag;
		/* 66 */ float	fAngularDrag[3];
		/* 69 */ float	fSteeringTorque[3];
		/* 72 */ float	fNudgeForce;
		/* 73 */ float	fStrafeForce;
		/* 74 */ float  fStrafePowerUsage;
		/* 75 */ float  fMaxBankAngle;
		uint	iDunno6[4]; // something about hptypes
		/* 80 */ uint	iMaxNanobots;
		/* 81 */ uint	iMaxShieldBats;
		uint idunno[20];
	};</struct> 

I see there was something identified to do with hptypes but it’s a mysterious unknown. I was wondering if anyone had any idea how I could work out the amount of guns / turrets a ship had.

You could use

CEquip *equip = cship->equip_manager.Traverse(tr);

and

EquipDesc ed;
		equip->GetEquipDesc(ed);

Very cool, but I don’t have access to CShip. The thing I am hooking gives me a Archetype::Ship* object instead. Is it possible to get the CShip value from that at all?

The unknown is a vector consisting of HpAttachmentType and a vector of CacheString. You could process the vector directly, or use [c]get_legal_hps[/c] with each type. You’d then have to look at each CacheString and count the unique ones (or maybe you could get away with the one with maximum length).

[Laz]

Interesting. We don’t have a definition for HpAttachmentType (just a blank enum), so I’ll probably run some checks later on to log all the possible values for it.

Which unknown do you mean? iDunno12[19] or iDunno6[4] or idunno[20]

[adoxa]

iDunno6. Here’s HpAttachmentType in FriendlyFire’s GitHub.

All the work has been done for me. Fantastic. Thank you all!
