So basically I'm trying to find static pointers for a Java game..... I can use pointer scan and find up to 200+ static pointers to the same address. I'll continually restart game etc to rule up certain pointers....

But some pointers completely change if you restart your computer, and some pointers completely change if you just reload the game.....

So I can't make a trainer with this java game, because the pointers constantly are changing...... The pointers that are green/static always change....

Firs thing when dealing with the pointerscan: You MUST rescan to filter out the wrong addresses, don't even bother using the results after the first pointerscan. (and do at least a level 7 scan for this kind of games)

A static address is just a memory location that is easy to find that points to another address. That other address again points to another location etc...
One change in the path that it follows will change the endresult of the pointer

So perhaps the address the static address points to changes, which is 100% normal and expected. Especially when you restart the game. The trick is finding the one pointerpath that is still valid after that


Also, you say it's a java game which means that you're probably running it in a browser, which means it's almost impossible to find a usable pointer. That is because the page is build up on which order the objects are loaded. So if an image is loaded before the java game and the next time the image is done loading after the java game, the pointerpath will be different.
Only way to use a pointer on a javagame is loading it in the standalone java player, and NOT in the webbrowser

Ya, I thought I said I did multiple scans after closing out the game, and continually trying. I even got up to 15 scans one time, and the static pointers till eventually changed =[

If all went bad go back a few scans (I hope you didn't overwrite the old results) and try again. Perhaps a pointer that's 75% of the time ok is better than nothing

Also as I said, try a bigger level and structsize, and don't run the game in a webbrowser. and if it's a online game, give up

While we're on the subject, what's structsize?

sorry, I meant "Max offset size" as it's called in ce 5.6

it determines the maximum offset value it'll look for

e.g if the instruction that accesses a pointer is
Code:

mov eax,[ebx+100]
mov eax,[eax+500]

then it'll be found with a max offset size of 1280 and higher (500hex=1280)
But giving a smaller offset than 1280 will then cause the pointer to not be found
