Woow, I feel so stupid now...

Why do you use the sqrt of the sum of squares? I thought final vector is found by the sum of all 3 (2 in case of 2 dimensions) vector components.

Yeah, not changing the eax+40,44 and 48 won't matter much, the goal is the speed of 30 34 and 38 like you said.

And yes, CE mlp (offsets in order of reading, left is offset 1, right is offset 4):

Wasn't aware of the official format, pardon me for that.

And those pointers have been stable since I found them, they are always there pointing to the right address everytime I am using a vehicle.

I'm glad they can be used to filter the other addresses, although I do not know how.

Also there is a twist, those are (how can I say this...) unique velocity addresses, the addresses that are present in any vehicle that I use.

But some vehicles carry more addresses if they are bigger and others less if they are smaller.

For example: A car only has 3 velocity addresses for each NS, UD and WE but a tank has 6 for each. These addresses are always coupled together. (I suspect that they are related to parts of the vehicle model which are responsible for physics effects, ie: tank hits a wall but his turret moves further due to cinetic energy, etc)

But that is not very important for now since the main address is sufficient as a starting point for all this adventure.

Nop, the address columns never change once I spawn a vehicle. I tried all you asked and no change.

And a few additional notes:

If I change map I lose my vehicle

If I exit the vehicle I can still control it like an RC car, using CE of course

If my vehicle is beyond the map rendering range then I cannot control it (basically once this happens the game is telling me that the vehicle does not exist anymore until it enters my rendering range again)

So does this mean that it is also stable in micro?

EDIT: It's as if once the vehicle is spawned and within range I can control it however I want with CE, even if I am not in the driver seat.

OK, last question. If you are in main menu, pointer just points to 00000000?

And just after map is loaded, it still points to 00000000 ?

I meant: in main menu just after you launch game, not the options/pause/inventory menu.

Never mind. I can try to make another AA script, today or tomorrow. I think, I'll use FPU.

Oh I understand where you are trying to get, you want to see if it targets any other address that might cause conflict when being modified.

The answer is the same, from game launch till I get in it it always points to 00000000

OK, see you tomorrow.

Of course, there can be a typo, etc.
Test it. You can edit line 12,15,20.

That is amazing!

I just tried it and it crashes the game and I did replace the game.exe with the correct one.

I am not one to know this or comment the amazing coding you provided but it seems that it is affecting the opcodes that handle the deltas and addss opcodes but not the opcodes that handle the velocity, which are

Ok, we will test pointer only (this script shouldn't change anything)
And of course, replace game.exe

1:50 AM here, I go to sleep.

I modified the "jmp hack" to "jmp testing" because you might have forgot that one. I can activate and deactivate that script and the game doesn't crash so the pointer is correct.

You help if you want and when you can, I got no hurry on this and you have been a great person helping me this far. We will continue this next time.

I have also ran the vector calculations to see which was the correct one and yours is the correct one : sqrt(x^2 +y^2 + z^2) mine isn't.
