One quick note, is I'm pretty sure the "check various angles" approach is very much not the traditional anti-grav approach, and is closer to min-risk movements actually. The 'traditional' anti-grav approach is simply summing up a 2d total force vector rather than checking angles. --[[User:Rednaxela|Rednaxela]] 02:48, 21 January 2010 (UTC)

:: I am not really sure, but I for one only think of advanced tutorial at that time of discussion. I myself prefer pseudocode for advanced tutorial, and bot building for basic tutorial. I don't believe pseudocode is suitable in such situation -- it won't make more sense than just literal explanation. But for advanced techniques, sometimes you can't explain it with literal explanation, and giving the code is just spoil, so I prefer pseudocode. Any one agree with me on this? And since this article cover from data gathering, I consider this a 'basic' tutorial. --[[User:Nat|<span style="color:#099;">Nat</span>]] [[User talk:Nat|<span style="color:#0a5;">Pavasant</span>]] 15:46, 21 January 2010 (UTC)

Revision as of 16:57, 21 January 2010

I'm posting this in it's current form because it took me a lot longer to write than I thought it would, and I don't want to lose all of my work. I would appreciate any ways people could improve it; please go ahead and change anything you can! I'm not exactly a Robocode guru, and there's still stuff that needs to be added to this--CrazyBassoonist 02:38, 21 January 2010 (UTC)

I'm not sure everyone agrees (though I think that is a good style). When we discussed tutorial style on Category talk:Tutorials, it seemed most people preferred to have pseudocode tutorials, not the explicit bot building style I use in the Wave Surfing Tutorial. --Voidious 15:22, 21 January 2010 (UTC)
I am not really sure, but I for one only think of advanced tutorial at that time of discussion. I myself prefer pseudocode for advanced tutorial, and bot building for basic tutorial. I don't believe pseudocode is suitable in such situation -- it won't make more sense than just literal explanation. But for advanced techniques, sometimes you can't explain it with literal explanation, and giving the code is just spoil, so I prefer pseudocode. Any one agree with me on this?
