Making variables "un-hackable"

BlitzMax Forums/BlitzMax Programming/Making variables "un-hackable"

Maybe "unhackable" is over-zealous..............BUT!!!

My game in development is going to have an online score system. I know that you can use programs that allow you to find the variables via hex editing. I used to use hex editors in the dos days, and I'm sure the ones out now I by far more powerful. Its how people make "trainers" etc. They find out what things need changed, etc..

Ok so I'm a bit afraid someone will find the lives variable, the score variable, and maybe other variables that will allow them to obtain a high score and cheat the online scoreteable.

I was wondering what logical methods are used to prevent this, or atleast make it so friggen hard that it would take hours to crack.
