To move with isxeq2 you have to press a key. Using 'face' + 'autorun' is the best option because once you start running then you can just 'face' at any point to change the direction without having to press another key.
I've searched many times for a way to do movement without keypresses; however, every time I come up with a new 'method' it always comes back to the same thing. I'm convinced that the game ONLY does movement based upon a keypress....at least, traditional movement that we think of as 'movement'. There probably is ONE function somewhere that would be the gateway between the keyboard and the server ..however, it's buried so deep that I can't find it in 5 years of looking.
