How to Access Pet Max HP?

[fuat21]

Hello,

I'm working with the Devkit on ECSRO client for fun and to improve myself. My main goal was to add an auto potion system for pets. I successfully implemented the auto potion GUI, but the main problem is that I can't access the pet's max HP.

As far as I understand, the ECSRO client doesn't store a direct max HP value for pets—it seems to calculate it dynamically using attributes like attack, defense, level, etc. I've managed to find values like current HP, type ID, unique ID, EXP, attack, defense, and more, but without access to max HP, I can't fully implement the auto potion feature.

I also tried hooking the COS UI function, hoping I could extract the max HP from the COS info screen as text, but I wasn't successful.

Please note that I'm a newbie developer, not a professional—this is just a learning project for me. If you have any ideas on how I can access or calculate the max HP value, I'd really appreciate your help.

Here’s the structure I have now ;

DWORD_PTR baseAddress;
unsigned int currentHP;         // +0x000
unsigned int typeID;            // +0x00C
unsigned int minPhysicalAttack; // +0x020
unsigned int maxPhysicalAttack; // +0x024
unsigned int uniqueID;          // +0x030
unsigned int currentEXP;        // +0x038
bool isValid;

The maximum HP for monsters is in the database itself _RefObjCommon -> _RefObjChar.MaxHP, equivalent to the characterdata_xxx.txt in the client files.

If you're talking about using SRO DevKit, then you should check the GlobalDataManager->GetCharacter(RefObjID)->GetData()->MaxHP.

Thanks for information but not Character Max HP, I already got it, I can not access COS MaxHP

in database _RefObjChar and media chardata in media

I need to access it with Devkit.

It's the same. There is no distinction but the RefObjID (_RefObjCommon.ID), all the character related data is stored there in _RefObjChar aka characterdata_xxx.txt in the client.

You should definitely take a look to the SRO DevKit project because it seems you're reversing stuffs, you'll find many similarities on other versions so better to take a look:
I described already how you're supposed to get this data through SRO DevKit.

I already checked it, but you know what's weird? In old clients like the Chinese testing version, there's no directly stored value for the COS's max HP. I even found a comment about it while checking in IDA. For some reason, Joymax developers preferred to calculate the COS's max HP dynamically using values like level, defense, attack, and others.

That's why I can't find a memory address for it using ReClass or Cheat Engine. I've found every piece of information about the COS except for the max HP. That's why I was trying to hook the COS info window, since it displays a text label like "CurrentHP / MaxHP (%Percent)." I thought I could hook that function and retrieve the max HP from there, but it wasn’t successful.

So now, I need a new approach.
