That only worked on one game for me. They aren't the cause of your linked health. Its a headache for me too lol its very annoying.

Didn't you run into this in many games? I noticed that all the functions that had "HealthComponent" always was shared with the enemies. And some of the "PlayerComponent" weren't connected to the enemy in any way.

I compare everything to the android version of the game, which has actual names for the functions. It makes everything wayyyyy easier.

Well if you actually challenged yourself you could figure out things on your own and your own methods that what I did

Well, I am running out of options. Remember when you told me about EOR? That literally got me exactly were I wanted to be, and I ended up hacking the game score. But FOR THIS, ANYTHING THAT RELATES TO NOT DIEING IS ALWAYS SHARED WITH THE ENEMY.Except for fall damage which I was able to prevent, but is so useless, since fall damage subtracts very little health.

If you have an offset for fall damage, why not make it increase your health by a ton if you can't figure out how to unlink? The only downside is that you'd have to make yourself fall to apply the hack but I think its doable

That is exactly why I tried to do. There was a VSUB.F32 which is apparently what subtracts my health when I fall. I NOP'D it and I no longer receive fall damage. But when I changed it to VADD.F32(with the correct registers), it subtracted even more health.

that doesn't sound right at all. Health has to be positive. if the health that was to be subtracted was a negative number (which would prove why changing it to VADD subtracts more health) by the rules of subtraction, when you get hit your health should increase, not decrease. Here are two cases:

First case: you have 100 health and the enemy hits you and that enemy deals 20 damage. Lets say that VSUB.F32 D0, D0, D1 is your instruction (D0 = current health, D1 = health to be taken)

100 (D0) - 20 (D1) = 80 (now D0, your current health)

changing it to VADD.F32 should make your health 120 (as I'm sure you know)

Second case: for some reason the game stores your health and the monster damage as negative. Same rules as before

-100 (D0) - (-20 (D1)) = -80 (now D0)

changing it to VADD.F32

-100 (D0) + -20 (D1) = -120 (now D0) makes your health even less???.

Third case: the game stores your health as positive and the monster health as negative, which wouldn't even make sense because you stated that the original instruction was subtracting, so the calculation would go as follows:

100 (D0) - (-20 (D1)) = 120 (D0, you get health when the monster hits you in the unmodded game????)

Changing it to add the values:

100 (D0) + (-20 (D1)) = 80 (D0, your health)

But now, when you mod it, the game now preforms the health calculation as normal which is not what you said happened.

Fourth case: for some insane reason the game stores your health as negative and monster health as positive.

-100 (D0) - 20 (D1) = -120 (D0, now your health)

Why would the developers keep subtracting 20 from a negative number? They would have no way of checking when you actually ran out of health!

Changing it to add:

-100 (D0) + 20 (D1) = -80 (D0, now your health)

(okay this kind of makes sense, but ONLY if the original instruction was not subtracting.)

I smell bs on your part. I do not believe that you have actually modded nova 3. I think you're one of those people that try and learn this, realize it is too hard, then try and take the easier path (and I can name more people than just you and I bet you guys know who you are) by using tools to show function names or compare against an Android game that has function names already visible. Then you get angry because this isn't coming to you as fast as you'd like it and spam help/support trying to get help on a topic and various things that you don't understand much at all. Do you really think this can be learned by making it as easy as possible for yourself? It took me more than a year and a half to get a good grip on IDA and it has paid off. I am discovering new ways to mod games that haven't been done before and finding my own methods to modding them.

"Oh look shmoo back at it again with his huge ego not believing me because he thinks he's better than me" no, I don't believe you because what you say doesn't make any sense at all.
