I know it's possible to do dereference inside gamedata with "read" "0", but how to do dereference in a plugin?


I need to do something like this (SomeAddress is the player's address)

PHP Code:

*(SomeAddress + 666) = -1; 


I've tried

PHP Code:

Address ? = (GetEntityAddress(?)) + 0; 


but I don't think it changed anything

[ampreeT]

Address pAddressToRead = view_as<Address>(view_as<int>(GetEntityAddress(iEntityIndex)) + iYourOffset);
int iValue = LoadFromAddress(pAddressToRead, NumberType_Int32);

Not sure about writing, but you could probably use StoreToAddress.

Thanks for the help, but dereferencing didn't solve the problem, but I got the answer to my question, so thanks anyway

The topic title is about how to make dereference in a plugin without using gamedata, not about what I need dereference for.

Also I said earlier that the idea failed then what solution are you talking about?

The whole idea was to change the target for the tank using StoreToAddress but apparently it's all hardcoded

Linux

PHP Code:

v12 = BossZombiePlayerBot::ChooseVictim((BossZombiePlayerBot *)LODWORD(a4), v68, 4, 0);
if ( !v12 )
{
        *((_DWORD *)a3 + 13) = -1;
        goto LABEL_7;
} 


Windows

PHP Code:

v38 = ChooseVictim((_DWORD *)a4, v37, COERCE_FLOAT(4), 0);
if ( v38 )
        *v30 = *(_DWORD *)(*(int (__thiscall **)(int))(*(_DWORD *)v38 + 8))(v38); 


On Windows it is perfectly visible that some function is executed while on Linux it is not present.
Apparently my way will only work on Linux, but that's just guesswork

P.S I know how to get a TankAttack class from a regular tank.

if you want to change the target of the tank in L4D2 you can use l4downtown2 (you need to look around the last pages for a more updated version) where there is a callback available OnChooseVictim or someting similar like that. where you can change the target. This works for all special infected apart from the witch because missing of the function.

Not sure how much would need to be changed in the extension to make it work in l4d1

I said earlier that windows is running some function, so even if I say about how to get TankAttack it does not help to solve the problem but maybe for Linux it makes sense, but I do not know how to get TankAttack on Linux

I know about downtown but I have no desire to install a large extension in which I will only use 1 forward, so I thought to find another solution.

off.
Interesting experiments. Good luck!
Please, share when you finally found a way to change victim.
