Pointers & Flash

If I remember correctly, finding pointers for flash games is more or less useless as they change each time the browser restarts.

Is this correct? If so, what are good alternatives to pointers? (Working on a bot for a flash based MMO)

creating array of byte
you write the array of byte replace the changing values with ??, change the function copying the new array of byte thats for begginers
Its possible to create pointers with cheat engine there trainer option, if u go to the LUA script thing through it u can create pointers, but how to make it I dont know
