Is there a way to do this?

I've got a game that uses a single code to add 1 currency. So if I do something in the game that adds 150 currency, it simply runs that code 150 times. I don't think there's a way to edit the code itself to make it add more than 1 at a time.

So my question is, how do I execute this script manually? Like, a lot of times?

Essentially, yes. I do.

The way I do it is as follows.

You need to find code that the game is constantly executing (like health display).

Have it jump to your code block which assigns the necessary registers and pushes whatever is needed to the stack.

Then you can call the in-game method (assuming you have the correct address of it).

Setup a little on/off switch so if it's off, it skips the call. Otherwise, do the call then turn the switch off.

Create a little script that turns the switch on when you both enable and disable the script and set a hotkey.

So that script sort of acts like your button to enable the switch and when the game gets around to executing your code, the switch will be on and it will be as though you called the method with a push of the button.

Right-click health and find out what accesses that address and then go back in game for a second and do nothing.
Often times, an instruction should pop up with several hundred executions already.
This is likely code that grabs the health value and uses it to update a status bar on screen.
So you would want to setup your injection point there.

You will, of course, need to know what values/registers the function you're calling requires.
Then you can simply use code like the following.

Correct. The default AOB injection also uses "jmp code" which you need to change to "jmp newmem".

You may also need to do another AOB scan to find the address of the game function you're trying to call.
Since it could change places on reload. Or you'll get lucky and it'll be static at game.exe+XXXX.

Really, unless the function is small and simple, you're better off making your own.

For example, you can use the same hook to read the current money amount, add 500, and then overwrite the amount. You may have needed to find the amount address using some other script (if it's not on the same struct available from the health code you're hooking). Then your button would add +500 money with each press.

Trying to mimic a game function that spawns a unit is probably going to be too complicated.

I would bet that the OP is trying to alter a value in an online game...which is why he is needing to use this odd approach.
Otherwise, as others have pointed out, there is no need to do it this way.
