if you use:

dist.x=(runspeed*key_cuu)+(runspeed_backwards*key_cud); //key_... are the arrows

you have to write then:

dist.x=(runspeed*key_w)+(-runspeed_backwards*key_s);

if you use:

on_key_cuu=move_frontwards;
FUNCTION move_frontwards
{dist.x=runspeed;}

you have to write then:

on_key_w=move_frontwards;
FUNCTION move_frontwards
{dist.x=runspeed;}

I hope you know how I mean this...
