I figured this out myself,
In this tutorial, i will show you how to make tyour hp regenrate after getting hit.
note: you can still die, but if they hit you a couple of times then stop and ur left on 20 hp, it will go back to 100. this is good cuz ppl dont realise that ur cheating.
Step 1:
open your bypass.
start combat arms.
Step2:
join a game, open cheat engine and attach it to Engine.exe (combat arms).
Step3:
in the scan box thingy, type 100 and click first scan.
a whole bunch on numbers and letters should pop up in the box to the left.
We need to narrow them down.
Step4:
go back into combat arms, throw a grenade, stand close to it so that you get hit, but dont die.
lets say that you hp is now 63.
go back to cheat engine, now instead of searching 100, type 63 and click NEXT SCAN
Step5:
if there is only 1 address in the box to the left, double click on it.
if there are more then 1 in the box to the left, repeat step 4
Step6:
after double clicking the address, it should appear in the box at the bottom.
double click the value (in my case, 63) and change it to 100.
then check the little check box on the left and go back in combat arms.
if done successfully, when u get hit, it should regenerate the hp back to 100.
happy hacking!
