'HandleAnimEvent': member function not declared in 'CHEVScientist' Created 3 weeks ago2024-12-27 15:39:41 UTC by GoldSrcJuju

(also if it helps, i'm new to HL coding.)

I see issues like these a lot, where beginners try to add/edit NPC code, weapon code etc., but some basic error happens and they have no idea what they're doing nor how to fix it.

If you knew what the error meant, you would realise that this class here is declared as well as its methods like Spawn, Precache and others:

class CHEVScientist : public CSquadMonster
{
public:
void Spawn(void);
void Precache(void);
int iSpikes;
int Classify(void);
void SetYawSpeed(void);
};

However, you are defining or implementing a method down here:

//=========================================================
// HandleAnimEvent - catches the monster-specific messages
// that occur when tagged animation frames are played.
//=========================================================
void CHEVScientist::HandleAnimEvent(MonsterEvent_t* pEvent)
{
...
}

Which is not declared in your class above. If you don't understand what I'm saying (methods, implemented, declared), then:

Learn the basics of C++, learn what a function is, what classes are, what declaring is, what members are, spend a couple months experimenting with C++ writing console apps or maybe even using a simple framework like Raylib, write a mini Half-Life SDK for studying, learn how to read code and study it, and then come back to this. Do not learn C++ while simultaneously learning the HL SDK - you will have a really hard time otherwise.

I'm familiar with C++, as I have done mods for other games using it + coded my own game. I just haven't been able to find this out.

I have my doubts, but okay. In either case, you should have a good idea of what to do now, i.e. declare that method.

OP says they're familiar with C++, but posts forum thread asking for help with the most basic beginner programming issue
