Hi, im trying to incorporate 2 scripts into one, but im finding issues and don't know how to solve.
I come here for guideance.

($lua} scripts run before the AA script gets executed as their result becomes part of the AA script. (e.g could be an alloc as well) so it can not see where getAddress"[VehicleMainPtr]-644 is going to be

the first lua block seems to so what you want

Hi, thanks for the answer.

If i understood you correctly, placing that first lua block on top of everything should setup things for the rest to work.

I did that, but still it complains, this time it says that in the second lua block there was an attempt to compare a number with nil, on top of that, the asm bit is not setting the values.

What am i missing?

[careca777]

Still no solution for this as of yet. Only way it runs is if the first lua block runs separately first.

Get rid of alloc(...) - globalalloc also allocates memory

This is still a problem I don't think you understand:

Ah, i've made the click, Thanks.

I guess there's no equivalent in lua to:

registersymbol(VehicleMainPtr)
globalalloc(VehicleMainPtr,8)

is there?

Tried to insert it with:

I think i tried everything a newbie like me could.

There's not much anyone on these forums can do if you're incapable of reading and understanding your own code. Go look up a Lua tutorial online so you can learn Lua- e.g. what the "return" keyword does.

I still think you're needlessly overcomplicating this and you'd be better off using a memory record + hotkey.

[careca777]

You're correct in that I don't know enough to solve this.
Let's say I do the memory record, create a header with the pointer, what happens if I have 3 pointers but only one is valid at any point in time? This is why I was going with lua, because the next step was going to be retrieving the valid one for use. Also I need to multiply some values and divide others.

EDIT: In the screenshot the output for VehicleMainPtr address is correct, but the addresses i got in the table which use the symbol are not updating.

EDIT2: using this code

[ParkourPenguin]

Sounds like you have 3 bad pointers and you should be using code injection to get the address instead (search "injection copy").

"globalalloc" allocates memory and registers the symbol. You're undoing that with unregistersymbol (effectively leaking the globalalloc) and re-registering the symbol at some other address. Use writePointer instead, don't execute anything if syntaxcheck is true (you're not returning anything to check), and don't format the address into a string before passing it to writePointer:

Hi, thanks for the reply! We did it! It seems like what i was after was the writePointer instruction, searched for it after seing your post, but it seems like it's not a common instruction, could not even find a page in wiki about it.

An explanation about the pointers: When i get into a car, a certain opcode will give me an address for the car's acceleration, for example, but if i get into a bike, it will be another opcode, in another kind of vehicle, yet another opcode/instruction.
So what i did was get a pointer from each type of vehicle, this way i don't need to inject everytime i change vehicles, the pointer will assume the correct value, now, of course, if i only "look" at one pointer, it will be wrong for certain vehicles, but another one will be correct/valid.
The pointer for the cars is always correct for cars.
The unregistering and then registering again the symbol, was something i saw in a table i found, was a trial and error kind of thing, all the while feeling that it didn't make much sense.

Thank you very much, both, for your kind help to a noob like me.
