Hello fellows.

My question is: IS it possible for a medic to heal an opponent?
Where does the infection and healing get handled?
I actually just want to hook the function, find the healing function (original) and copypaste it so that the medic only heals everyone.

I am running an RP server so it would be really great to have the medikit working for every team.

Anyone got an idea?

PS: Anyone knows how i can disable ammo-drop after getting killed or dying?
PSS: I know it's not possible normally. But i want to recode that somehow

Looking at IDA, when you hit with the medikit, it calls CTFMedikit::AxeHit().

And inside, to check whatever you can heal this player, there is just a simple function for that: CBaseEntity::IsAlly().

This function is about basically checking if current healer's team is an ally of the target's team. Technically this does that by checking against the global array teamallies[5].

Array which is filled like using value from info_tfdetect entity:

[1 (blue team)]    = "team1_allies" keyvalue
[2 (red team)]     = "team2_allies" keyvalue
[3 (yellow team)]  = "team3_allies" keyvalue
[4 (green team)]   = "team4_allies" keyvalue

I don't know exactly how works TFC and what you're doing, but I guess you could do:

- Any healers would be for example only the Green team, and you setup team4_allies to 14 (all teams), so Green team is an ally of others teams. But I'm not sure how it will affect others weapons or such. Just an idea.
- You hook CBaseEntity::IsAlly() with Okapi/Orpheu module, so you can control the return.

Thanks for the anwser and the post. Where do i find those files that i can open with IDA that tell me such things (Directory).

[Arkshine]

There is no source code. IDA is a tool to disassemble/decompile a binary file (tfc.so). It helps to understand better things.

How did you know which function the game called (through IDA) ?

[Arkshine]

By reading what I see? lol
You should use IDA with linux binary since there are functions symbols.

[Shooting King]

Yeah with linux binaries only, I am asking how come you know exactly that CTFMedikit::AxeHit() function is getting triggered ? Any runtime debugging or something like that ?

[Arkshine]

You see it at the decompilation code.

[Shooting King]

Still didn't get you. I opened IDA, all functions loaded, have de-compiled to .c . Now should i search the function one by one till the relevant function name (like 'Medikit AxeHit' in this case) is found ? And after guessing the function, how can you test that it is actually being called by engine ?

[Arkshine]

Actually I did not try to find from where it's called.

Thread is about medikit, so all you have to do is to search a class which is similar to what you search. Here you find easily CTFMedikit in the list and you have all the relations functions:



From that, OP wants to do something when you heal, usually you would look for PrimaryAttack, but here the only function which makes sense is AxeHit. Then inside you see it uses IsAlly(), etc. I did not do more than that and I don't know from where it's called if it was your question because it's a virtual function and it's not easy to find references from that.
