Rockbox games

1) random_int = (rb->rand() % 5) + 1;

5 is the range. 1 is the lowest possible number. % means modulus (remainder of integer division e.g. 15 % 4 = 3). rb->rand() returns a random number from 0 to some defined really big number.

2) There is a "goto" statement, however it's use is mostly frowned upon because it can lead to "spaghetti code".  It's generally better to use functions.

3) Use "return PLUGIN_OK;" in the plugin_start block.

Thank you for the reply. Little problem with answer #2 - I'm still a complete novice and have no idea how to implement functions yet. I'll try to learn how to use it; but until then, can you give me the exact syntax for the goto command? (I'd mostly like to use it to test functionality when the "first draft" is completed.)

This forum is hardly the place to learn C. Why not find a good online tutorial on C?

[saanaito]

I have. And I'm trying to code as I go, but I skimmed through the whole thing and couldn't find the command I want. As mentioned in the linked post, there are oodles of tutorials out there, and it'll simply take WAY too much time to seek out what I need. (I'm a high school senior at the moment, and my main concern right now are the three research projects I have due this month.) I do what I can in my spare time, but it's so limited lately....

Besides, it's not like I'm asking for a lot of help, just a few tips here and there....

I didn't mean "there's so many tutorials out there it's hard to wade through the crap ones", more like "there's so much (good) information out there, google will answer any question you could possibly have".

If for whatever reason google doesn't help you, you could join a programming forum.  Although I appreciate it might be hard to tell if something is C related or Rockbox related, so maybe they'll let you ask in the #rockbox or #rockbox-community IRC channels.  If you're extremely desperate you could PM me, though I'm probably the worst "programmer" I've ever seen in my life.

I'll remember that. Thanks for the help!

Damnit, I was going to edit.  

You might want to read some of the stuff under "Getting Started & Compiling" and "About the Code" linked from here.  You probably won't understand all of it now, but some of it might be helpful.

You have to understand, we want the "search" feature in this forum to bring up relevant results. So if someone searches for something Rockbox-specific, we generally don't want it to turn up standard C help that's available everywhere. As you said, there's a million places on the internet to find information on C. No sense wasting time here when you can get it faster there, and not dilute search results.

We're glad to provide help where applicable, but both the random thing and the goto thing would've honestly taken you less time elsewhere, if you'd just searched a tutorial.

i accidently removed my bubbles plugin,is there any where i can get it back?

[LambdaCalculus]

Download Rockbox again and unzip it to the root of your device. You'll get Bubbles back.

This may be a dumb idea but its just a thought.since i have seen alot of people wanting games but its just to complicated for them to write them there self (including me)why not make a converter that can get flash games (or some other kind of game you can find on the internet) and convert it into the rockbox format.

is this possible?

[LambdaCalculus]

That would still require a rewrite of the game in question. And also, Rockbox is NOT a game-oriented project; it is an audio playback-oriented project.

If you want a game so badly, either learn how to program, or just buy a PSP or Nintendo DS. End of discussion.

You may as well just rewrite the game.  Without even mentioning how to write something to convert flash to C for rockbox, the requirements for a game that runs on a 2 GHZ PC with 2 GB of RAM (I know flash games aren't quite that bad) and a DAP with a ~100 MHz processor and 32 MB of RAM isn't funny (plus the control differences, no malloc etc).
