Calling a code cave from a trainer

[pikachu5501]

I have a small question to ask. Let say that i made a code cave that would refill my hp for example. there is anyway that i can call an opcode adresse from the trainer itself when i press a hotkey for example (in C++)?

thanx in advance.

Edit context of the process to change EIP to your code cave?

Im not fully sure what you want but...

A code cave is being read when you initialise it from a trainer.

If you mean to call on the code cave at any time? then that is potentially dangerous as you could be calling the opcodes at any time and when the registers are different.

caki is right. If you want it happening at any time, your only way is via registers. Memory Hacking Software can do this I think, through scripting. Otherwise, you'll need to find a constantly accessed code and re-route it to your cave (doesn't necessarily have to be accessing your HP).

btw, sorry for the long reply. I wasn't near my computer for a while (night school).

If i have a second look at my question, yes, it is silly in a way if reg change all the time. I just wanted anyway to refill my health from a "function". Anyway, i found other way to cheat health other than just changing value (via codecave) like detecting a colision that call the dec function and all. When i have 5 minute, i might go around thoses new options.

Thanx all for you reply and sorry sometime if i post silly questions. I am still a "newb" about trainging sometime.
