On a certain online game, related to the anime SAO, has XP you can earn.
Being a total newbie at hacking i have managed to find the address of the EXP, and yes, i'm certain, however, as i attempt to change it, the value either stays the same or turns into another value. The value is a "double" type, and another value for some reason changes with it and is of the "byte" type.

Some please help?? Crying or Very sad

LOL.... I found the same code, but couldn't change it. btw... be more specific cause this SAO game is within roblox. People might think it as a free game that was downloaded anywhere.

Well what can we do then? If we find code and we cant chage it, accessing what writes to this memory will shut the game down -__-

Your seriously trying to edit EXP in an ONLINE game?

Most value's in online games are server sided thus unchangable.

If you have luck the programmers of the game messed some things up and you can edit walk speed, delay of skills, attack speed but as said only if you are lucky and the values are not server sided.

To do this learn basic debugging in Cheat Engine and Auto Assembly.

For example this is a code for an online game that removes the game writes to the game speed value (if the address was the real one since I don't want to see this game ruined) and changes is to 0 (which is the fastest for the game). Word of warning I'm a total beginner in auto assembly and this code is very ugly by applying a nop while it could be done in a nicer way.
Code:

[ENABLE]
//code from here to '[DISABLE]' will be used to enable the cheat
alloc(originalspeed, 9)
registersymbol(originalspeed)
aobscan(gamespeed,94 65 A3 2? 23 7F 1A 12 16)
registersymbol(gamespeed)

originalspeed:
readmem(gamespeed, 9)

gamespeed+2:
db 90 90 90 90 90

[DISABLE]
//code from here till the end of the code will be used to disable the cheat
gamespeed:
readmem(originalspeed, 9)

unregistersymbol(originalspeed)
unregistersymbol(gamespeed)
dealloc(originalspeed)

Secondly I wouldn't expect much more help than this since discussing online game (hacks) is not allowed forum.cheatengine.org/faq.php#0. (and I'm not allowed too post links yet Sad)

If you ever use this template for AA just add it first with only enable/disable and the rest empty else CE will not allow you to use it because the syntax check cannot read all of the memory.
