Welcome to Patater

Hi,

Thanks a lot for updating your files to support grit 0.8. Also, thanks a ton for the manual!

With versions of grit greater than 0.8, a problem where graphics are not converted correctly has come up. I've updated the included grit files to explicitly tell grit that we want bitmap graphics or tiled graphics in each case. This fixes the issue for anyone who has been experiencing it. (I'm looking at you Musturd, hansi, and Anonymous.)

Thanks for the heads up, guys.

Your manual is great !!!
But I prefer to read printed manual. If you upload docbook version, I can creat pdf version manual and print it.
(I think that you wtite this manual in docbook format and convert it to html. Is it right???)

Clean install of devkitpro, trying to get chapter_5-backgrounds to build... (all devkitpro examples compiled fluently).... Looks like grit isn't nice to me?

Sorry for being total newb

thanks. I am just a beginner, this is very useful for me

10-Q so much...

All the comments are written in the same style, are all positive and are all by an anon commenter. This has lead me to believe that you (the manual writer) have written these comments yourself to advertise your manual. Great tut BTW

Generally a nice guide, but I have to quibble with the way the wrapping of the ship sprite is handled. My understanding is that the wrapping will be handled automatically when the sprite is displayed, but it won't be handled in the actual game logic. So the way you're doing it is kind of cheating, and it could break in certain circumstances. For example, your floats will lose precision as they grow larger, so you could break the code by going in the same direction for a while. (I don't know if this would ever be a problem in practice, but it's something to watch out for.) Or you might want to do something depending on the ship's position, and you'll have to have logic to handle wrapping then. It's OK to have it this way if you understand the problems, but you don't indicate them in the tutorial. You say "The hardware takes care of any wrapping or offscreen issues," but it's not the case that it handles ALL potential issues.

Thank you for your time and share your knowlege. Thank you so much.

I learnt from your tutorial when it was on v5 (or maybe previous one). I just re-read whe whole thing, and found much information which i'd love to get the first day i decided to get into the homebrew thing. Namely, the "Which Passthrough Should I Buy" is a jewel in clarity compared to the extensive history you find on other sites. Too much info drowns the newbie (i was;). Stating that slot-1, homebrew/nopass compatible carts are what you want is giving the right information to start with. You could also list the MK5 in the among the slot-1, as it works for me so far, and does provide integrated memory (some find it a con, other a pro).

Concerning the content itself, i found it even clearer than before. More readable, better commented (moreover, block /* */ comments makes it less fuzzy-looking). And thanks for the whole multi-sprite "Sprite Tile Addressing", "Loading in a Sprite" & boundary parts, "Sprite for dummies" made it all a lot clearer for me ! Again good idea to speak about assertions, and the Object-oriented programming part is a breeze.

The only "enhancement" i would advise would be some kind of code syntax highlighting. That's not easily doable using DocBook format (you would need some kind of brute-force copy/paste from something similar to devcpp's html export, for example), but would render the code snippets easier to grasp and navigate through.

Your document is a real pleasure to read, and learn from, really good work ! IMHO, it's the est thing to read when you're beginning DS programming. Figuring out the concepts is the most important thing, and it's easy with your explainations. Bookmark well deserved !
