Appreciate it if someone could please help.

I have in my table this:

Description........Address...............Type..........Value
Current............p->09D50B2C.......4 Bytes.......2 <---- Value of interest

(Sorry for the dots as I do not know how to do TABs to separate the text)

The pointer is made up of address and Offset as shown below:-

Pointer:
Address: 0069CCFC
Offset: 4

What I want to do is if I can:

Use this value (2 in this case) for Current Hero to calculate another pointer address like so:-

Address: 0069CCFC
Offset: [Current]*0A

ie Offset=Current X 0x0A

Is there a way to do this as above or in script perhaps?
I don't know where to start.

CE table entries cannot refer one another natively, but they do accept some degree of math.
Meaning, +0A works.
You need to test if multiplication works (I have not tried that, ever).
If I understood your needs correctly, this comes to mind (put this into address field)
0069CCFC+[0069CCFC]*0xA

Be vary of fixed addresses though.
You might be better off with a script that grabs the base into, say, pBase and use this in the address list instead:
[pBase]+[[pBase]]*0xA
Or, just do the math in the script itself and expose that directly.

Multiplication works with numbers but will try your suggestion and see what happens.

thanks.

Edit: Just tried something and it seemed to work.

I have this:
Pointer:Hero
Address: 0069CCFC
Offset: 4

I wanted this:
Address: 0069CCFC
Offset: [Hero]*0A

so I tried using your idea and expand it to:

Pointer:
Address: 0069CCFC
Offset: [[0069CCFC]+4]*0A

and low and behold it worked!

Thanks for the idea. Very Happy Very Happy Very Happy Very Happy Very Happy Very Happy Very Happy Very Happy
KUDOS to you man!

Now I have to double click in the address in order to refresh the value.
I expect it is because I am actually doing a double pointer by [[xxxxxx]+yy]

But still it is a whole lot better than before. Before this I had to manually edit the values. now with this I only need to manually refresh the value by double clicking on the address and click ok.

It works and I am a step closer to solving this.
Now I just have to write a script to refresh the table every sec or so.

Have any ideas?

Seems I missed that +4, but good to see you got it figured out.

I think you can do that refresh with a LUA thread or timer.
You need to ask in the LUA forum, I'm still more of an ASM guy Wink
