I'm trying to create a meter in a co-op game to see how much damage per second each of us are doing. Unfortunately, I just can't wrap my head around how to achieve this. I've found a function that updates the health of every unit in the map, but this function constantly writes to every health address--not just when something changes. This is all I have gotten so far, so I could use some advice on how to approach something like this. I'm hoping to be able to trace back the source of the damage, but I'm quite lost.

Thank you very much!

Some options you have:

1. Continue with the function you have found. If you go this route you are going to have to record every address being written to with an id of some sort to determine differences in health. So each time it is written to, you can check back to a stored value, compare them, and find out if there is a change and handle it accordingly.

2. Look for another function. Such as the damage function rather then the update health function. If the damage function is shared, you could have the ability to determine who caused the damage and who it is being caused to. Which should help determine specifically who did that damage.

Wait... what do you mean damage PER second? I mean, you find out how much damage you deal in ONE shot, and then figure out how many times you can strike in a second, and just multiply the two no? I mean if the game has splash damage then the number wouldn't be constant anyway.

No, damage per second is the total damage divided by the number of seconds that have elapsed.

I would choose option 2 from atm0s.
Use the current instruction you have to get a monster's health address.
Then find out what writes to that address when they take damage.
Hopefully this new instruction is not used when the monster is healing.
That same instruction should effect all monsters (maybe even players).
