I can't find the pointer from a double value.
This is what I do:
Quote:
Right click on the address--->"Pointer scan for this address"--->
-Maximum offset value : 2048
-Maximum level : 6
Click "OK" (pointercount:4947)
Save it when it's done.
Restart the game.
Find the new address.
Go to the pointer scan tab.
"File"--->"Open"
"Pointer scanner"--->"Rescan memory - Removes pointers not pointing to the right address"--->"Address to find": The new address I found ---> click "OK"
(Pointercount:0)

I did this 5 times and I know that it is the right address but it doesn't show me any pointers.

I tried it manually with "Find out what writes to this address"
but then I saw this : "mov [rdx+somthing],something"
I double clicked it and it says:"The value of the pointer needed to find this address is probably 0xxxxxxx".
I clicked on "New scan" with 4 bytes and an exact value, hex enabled,
And I typed the address 0xxxxxxx but I found nothing.
(The address wasn't really 0xxxxxxx but I just forgot what it was)

There must be a pointer because the address changes everytime I restart the game or everytime I die.

Some more information:
The game is minecraft and the value I want to edit is the walkspeed (ws)
This is a picture from the debug screen from minecraft, it shows you the ws at the botom left ("ws: 0,100" is the default)
See attachment.

I know how to find pointers because I allready did it in the same game but that was a 4 byte value.

Try to increase (double) the offset value.

Before you can use pointers in java you have to launch it with -XX:-UseCompressedOops, otherwise object pointers are compressed

I'm now trying it with "Maximum offset value : 6000" and "Max level : 7"
I use 7 threads and it's allready 13 min :/

What do you want me to do o.O
sorry but I'm not that experienced.
But I allready found a pointer from another value in minecraft ...
why didn't I have to do it then?




EDIT:
I think I found how to do the parameter stuff,
let's try it


Edit:
I find the address.
Right click "Find out what writes to this address."
Change my speed.
I find this: [rdx+18]
I scan rdx with 4 bytes and with hex
I find 4 addresses.
I copy their address and click on "Add addresses manually"
Check the pointer box.
Fill in the first address I found.
I make the offset 18.
Change the type to double.
I do this for each address.
They all point to the right address and have the right value.
I right click on the pointers--->"Find out what writes to this address."---> "Find out what writes to this pointer"
I change my speed.
Nothing happens at the opcode thing window.
So that means there are no pointers after this pointer???

But when I die
All the pointers don't work anymore.

launch java with "-XX:-UseCompressedOops" and then try a pointerscan

try:
level 6, offset 3192
level 7, offset 2048

And yes, scans will take longer than 12 minutes. (they could take hours and even days depending on how bad it is)

Thanks it worked.
But why didn't it work when I tried to manually find the pointer?

you need to find what accesses an pointer, not writes
also, manual finding it can be difficult, especially in things like java
