Never fiddled with the brownian movement personally, I think I left it default, Generally as a rule of thumb, test in thin fluid as I've always tested it that way, and I think all the leagues use that, dont use vertical gravity for normal bots, its specialist sims that use pondmode and vertical gravity...
OK, I suggest taking purely the ANIMAL MINIMALIS movement gene, just looking at that solo, because its good at looking at the basic movement, also remember to have NO COSTS when testing movement, because otherwise your bots will loose their energy and die!
also, heres a great place to start http://wiki.darwinbots.com/w/Robot_Tutorial
because honestly, I looked through those...also rickdan, if you go to 'THE BESTIARY' on these forums, and go into 'THE STARTING GATE' you will see a few bots of mine, and a lot of them still in there use different eye and movement techniques...
Also a key point to know, after you grasp the very very basics on the actual movement commands, start looking at eyes, and movement with eyes together, because they very closely link, as a set of triggers and causes, such as in my new eye/hunting system, it'll turn for how far across the vision the prey is, so if its at the far left...it'll turn quite powerfully to face it, if its only slightly left, it'll turn weakly.
Also, after grasping basic lines of code, work your bots off either animal_minimalis or alga_minimalis, and test those 2 in action (ALGA IS A VEG BTW) and base most of your bots of them, because they're just the crucial parts for survival, so you can test 1 component at a time on them.
NOW FOR FIXING YOUR CODE:
10 *.up store
it should be
10 .up store
Heres a rule of thumb, if your changing something in a memory address (so if its inbetween start and stop normally) then its .SYSVAR store or .SYSVAR inc or .SYSVAR dec but if your reading what the sysvar has in it (so what number is in the eye for example) you do *.SYSVAR and if you want to ask what address (number/position...like an address up a road) you do .SYSVAR
in each of those replace the SYSVAR with up, down aimdx etc. this should help you understand sysvars http://wiki.darwinbots.com/w/Sysvars
