To be fair i have limited knowledge to this but i am guessing that using whatever debugger you are to find the offsets, search for a non-exact value or a stand value then take damage in the game and seach for a 'string, float, boolean etc.' (Whatever) which has dropped in value. Then when your health regenerates same process but higher in value.
Then try dying and respawning (this should reset fields in which have no meaning but to follow the health and other attribute fields and act as decoys.
When you are left with the 2+- values make it so when a button on your rtm *for example* it locks the value so it will not change, or make it a higher number e.g; standard health value=100, change to 10'000. This is also known as Demi-god.
Take what you will from this, otherwise youtube is your friend!
