I am attempting to make a script that when activated teleports the character to the mouse location. This is a 2D game so the player and mouse only have X,Y coordinates. I have the X,Y of the mouse and the player, the player is stored as a double and the mouse is stored as a float, I am able to teleport the player by doing

Specifically what is going wrong with the script? Is it not activating? Does it crash the game? Does it teleport the player unexpectedly?

What type of value is stored at mCord? (4-byte, float, double...)

When the mouse is on the player for any arbitrary position the player could be in, is the value at mCord (after any applicable value conversions) equivalent to the player's coordinates?

[Kronogenics]

It teleports the player unexpectedly. mCord is a float. The mouse cords are slightly off when I have the mouse over the player but it seems to be static (something I should be able to correct on my own)

[ParkourPenguin]

I don't think there are any errors with that script assuming mCord is correct. How is the value at mCord being written to? If it's another code injection, make sure that instruction doesn't also access other addresses.

[ParkourPenguin]

Oh. You're moving the address of the coordinates into mCord instead of the value. It would be better to say that mCord is a pointer to a float instead of just a float.

It's fine to do it like that. However, in the code injection which teleports the player, you need to dereference mCord one more time:

[Kronogenics]

That works perfectly. Can you explain what you mean by dereferencing?

[ParkourPenguin]

I'm mostly referring to the dereference operator in C. I may not have used it perfectly when I said "one more time," but it more or less refers to treating the value at an address as another address.

In your code injection which writes to the symbol mCord:

Thank you!

Also, it does seem that for whatever reason the left side of the screen when pointed to sets my mouse to -16, which means that my cursor and my player are not in sync. I said earlier that I thought it to be static, which it is not. How would I go about fixing this?

[ParkourPenguin]

I don't know what you mean by "static." I figured you meant to say it was offset by a constant amount (which I'm guessing is -16 relative to the player).

If the mouse is always 16 units behind the player, just add 16 to the mouse's coordinates before you write it to the player's coordinates.

[Kronogenics]

I don't know why I use the word static, you're correct, except it is not always -16 behind the player, as I increase the x cord of my mouse it will eventually equal that of the player and then surpass it.

[ParkourPenguin]

So one increases at a different rate than the other?

Just make a function that maps one to the other and I'll translate that into assembly. If you don't know how to do that, put your mouse cursor exactly over your player at arbitrary positions in the map, log the value of your mouse cursor's coordinate and the value of your player's coordinate, and post that data here (get at least 5 unique data points).

[Kronogenics]

Alright, I will do this as soon as I can, I have to leave school soon so once I get home I will do this. Thank you for your help! Also, if I wanted to make a static pointer to say eax during a specific instruction but I didn't want to inject upon that instruction (so that it doesn't move, making it inject able by a different script) how would I go about doing this?

I can't seem to understand this, your code worked for the X axis, but replicating the code and replacing the parts I needed in order for it to work on the Y axis crashes my game?
