Is there a better way to find the mouse coords?

I have tried Lab's method but I couldn't get anything since there were too many addresses which had changes so the list stayed at 208 mill addresses

This is for Grand Chase

You can use hotkeys for CE. Doing unknown then has changed, until you get your coords for the mouse pointer in the game itself.

Same as if you was looking for player coords.
1. Unknown scan using a hotkey
2. move mouse
3. Scan has changed using hotkey
4. move mouse
5. Scan has changed.
6 move mouse
7. has changed
* Keep going till you find it.

You should be able to find them doing those steps.
Other method may be hooking api to see the coords.

I took another try at this but I threw it unchanged value turned out a bit better I got left with 94 addresses.

(By the way my game is windowed mode)
When I move my mouse cursor within the game, ALL the values change

BUT when I move my mouse outside (on windows) only half the values.

Can I get some help towards where I should head now?

[Labyrnth]

All the ones that make a change outside the window of the game are not what you need.
Any that change in the window are what you want to weed through.

[SLaYaH]

I now have around 23 addresses.

Two questions, since I saved the number of addresses when I reloaded the game a bunch of addresses there stayed static or changed to 0.

Would the mouse address change everytime the game started?


Now I have 18 addresses
Ranging from:00CDD3FD - 00CDD670
the top half of them MIRROR the bottom half



Any suggestions?

Then any suggestions on weeding them out?

Also sometimes 2 addresses go negative.

[HalfPrime]

static vs dynamic would depend on how the game handles it.
Try doing increase/decrease instead of changed/unchanged. and only try finding one coord at a time

No, top is a lower value than bottom. As you go down, the coordinates go up. You could always find the initial mouse coordinates with something like GetCursorPos then hooking DirectInput will get you the relative movement and you can combine for absolute coords.

[SLaYaH]

Well I don't know much about using those kinds of methods which is why I'm trying to do it this way.

[Labyrnth]

It not a method it is how the screen coords work when a game or application is written.
Example rectangle representing screen or window.
x = 200
y = 100
Top left corner = x,0 and y,0
Bottom left corner = x,0 y,100
Top right corner = x,200 y,0
Bottom right corner = x,200 y,100

[SLaYaH]

Do games always use the bottom right of the grid?

Ack it didn't come out right I just noticed but basically an
X / Y grid and it being the bottom right of it
+

[Labyrnth]

Do you understand what was said?

The coords are anywheres within the screen starting from top left corner with x = 0 & y = 0
As you move down the Y axis increases as you move right the x value increases.
And reverse of this when moving up and left they decrease.

[SLaYaH]

Yeah I completely understood that but I'm just wondering if for ALL games is it like that?

[HalfPrime]

Yes. That's what windows uses -> That's what everything else uses. Unless they do some strange proprietary thing, you will see the coords like that.

[SLaYaH]

Thank you guys for all your help but I have one small question left ...

I have found the Mouse X / Y address(s)

The problem is I am left with 4 addresses
The numbers are the ending Addresses
Mouse X - 400
Mouse Y - 404
Mouse X - 66C
Mouse Y - 670

The two mouse x and y addresses mirror EXACTLY
Any suggestions on where I should head now?
