hi,

I am now familiar with scanning for addresses.
I Understand, I think scanning for pointers at least one method (don't know if there are other ways) after watching a tutorial on Youtube using CE (pointer scan for this address)

What to do if your pointer scan of an address returns a blank page?

The tutorial did not say but seem to suggest that all values have pointers.
So if I am thinking that if my scan did not return a pointer then it is displayed value as the tutorial said.

But the address is a valid address and not a displayed value.
example
address=xxxxxxxx value=1000
I get 1000 gold in game if I change the value to 2000, I get 2000.

What I did was, I wanted to learn to do tables so I right click on the address and select "pointer scan for this address"as learnt from the tutorial.
But this does not return anythig, just a blank page as I said before.

Q1. Does this mean that this IS the address where the value of gold is stored but there is no pointer to it?

Q2. So how can I create a table? I have looked at the memory around the address and located other values like iron and wood and food but they don't have any pointers either.

Q3. Does this mean that table is not possible? But surely if the program knows where the gold is then there must be a simple rule to find its location everytime the game starts. It could not be completely random.

Q4. does this mean that I need to write a script? Can anyone show me an example of a script when you have an address only.

Q5. Is this a limitation of the cheat engine in that it can only tell me what the address is in this case and I will never be able to do a table for it?

Q6. Does this mean that for some variables ther are no convenient pointers?

I am specifically trying to create a table for Empire Earth Art of Conquest for learning purposes (yes, I am really trying to learn. I can already cheat at this game)

Because I admire others who seem to make tables effortlessly unlike me
I would like to know about tables rather than relying on other s to make me tables.

I would really like to know the answers.

When do pointer scan, create pointer maps for better results like in this video.
If Default pointer scan brings 0 results which settings look like this:



Have to expand Offset value to 4094 and "Max level" from 6 to 8+:


If want to create a script which finds your value instead of pointer scan then:
Can google for stuff like globalalloc, to create a custom pointer from script.

"show advanced options"

- addresses must be 32-bit aligned (you may want to disable this for 64-bit processes)

- pointer path may only be inside this region (ensure its from 0 to FFFFFFFFFFFFFFFF for 64-bit process)
(although you dont really need 16 F's nor start address from 0)

- first element of pointerstruct must point to module (useful for C/C++ games ... sometimes)

- max different offsets per node (in case no pointers turn this option off)

- maximum offset value (default value usually enough for 32-bit processes, but if its 64-bit process then 4000 or 5000 is good)

- max level (default value usually enough for 32-bit processes, in case its 64-bit then 6 or 7 is good)

note:
in many cases increasing the "max level" first without changing the "maximum offset value" gives some pointers.

rest options for advanced / case-dependent uses.

no. (but keep in-mind you dont need pointers for static addresses)

file -> save / save-as

a cheat table may contain:
scripts, static addresses, pointers to dynamic addresses (which is also static addresses), headers/groups.
