MLlib seems to be old (searching replacement)

Indeed I can technically use MP3 but I don't like that format much
It's like a kind of sin to me to convert tracker format music to MP3, it's like cutting of WAV format :(
In other hand if I won't be able to convert or find few more "MOD" files, then I will have to use MP3 unless You will be able to code in XM/IT/S3M and others (or at least those 3 :P)

Also I have proved that it can be run on Dolphin
I had to only change CPU Emulator Engine to Interpreter, rest of settings worked on default as for graphics at least, sound is always problematic with dang PulseAudio so I don't blame it for not working yet : >

I will have to try to code some more today, at least music change...and maybe use of second WiiMote...or some intro screen...or options screen...oh man a lot of work to do T_T
Please try to code XM at least, good luck
It shouldn't be difficult, XM basically has more channels and some sound "extras" I think

I think you can convert any music file to MP3, and play the MP3 with MLlib. You can also play RAW. (see "Plop!" sources)

Nice to see your game out ! :)

Re: MLlib seems to be old (searching replacement)

iSubaru — Sat, 24 Jul 2010 13:13:07 +0200

Game is done sort of, now to add cosmetic things like music and such extras, I will try for now with going with MOD files only until You will make XM and others avaiable :D (maybe maxmod can help or mikmod?)

I have did meta.xml and icon as well, oh and few updates teehee (including VERY simple webpage)

www.wiibrew.org/RockBlueMet

Enjoy~ :D

Finally one game is sort of done
Now to figure out why second is hanging up (code dump) I have checked images and made sure they are 24bits...well time to take apart code again heh...

Re: MLlib seems to be old (searching replacement)

Minishlink — Sat, 24 Jul 2010 04:39:09 +0200

If you want to delete an image, call ML_DeleteImage(&image); but there is no point to delete sprite since it's just a couple of variables. ;)
I'm glad you figured out. :)

If you want some help, check out the source of my TicTacToe game, even though it's very old and it won't compile with the lastest MLlib.

Re: MLlib seems to be old (searching replacement)

iSubaru — Fri, 23 Jul 2010 13:55:22 +0200

Heh again my habits speaks for me, in DS programming there was no such idea for visible/non-visible of sprites because of a little limited memory compared to Wii, so to not make it overload we had to delete sprites, we can load them again of course but to save memory, there is deletion :P

I will try this if(Wiimote[0].Newpress.A) sprite.currentFrame = 1;
I take that "sprite" word is name of sprite loaded?
Lemme check it out, I will edit post in a minute or two :D

Sadly I found out that game can't go on Dolphin, at least one of users says that, I can't recompile Dolphin because of some global changes in libraries <_< I would have to add -ld library manually which I do not know how to do in scons...duh
Foreshadowing question, no I can't use "stable" 2.0 because it calls old libraries, I would have to screw up half of my Linux for this, not very good price...

Anyway off to checking, will edit in a minute

EDIT #1
Oh yeah, it compiled :) I will apply it to all instructions then and check out on Wii, if this will work, RC2 will be ready to go ^_^
Thank You a ton

EDIT #2
Well not exactly effect I wanted
On resetting to frame 0 as starting it goes fine but selection does this:
changes to frame 1 then to 2 and disappears
I will check if that's instructions bad coding or something...well at DS this way worked but who knows maybe I did something wrong there...

EDIT #3
If that changes anything, 8 sprites are loaded from one image loaded, so there is only one image and 7 "copies" of it names blocks0 to blocks8

EDIT #4
Ah one moment, maybe it collide with animation functions for sprites, give me a minute to try it out

EDIT #5
Yup that was the case, now I can continue with development, I guess today RC2 can really be done :)
Thank You a ton for help

We load frame 0 of 3-frame sprite

ML_Sprite sprite;

if(Wiimote[0].Newpress.A) sprite.currentFrame = 1;

That's it ;)

Why would you need delete sprites functions ? You can just set their "visible" member to false and they won't be visible anymore if that's what you want. Like :

sprite.visible = false;

I can't try your game right now because I'm in holidays/vacation in California, USA; so I don't have any Wii. I come back to my home in France the 24th of August... :\

Let me now if that's what you wanted ! ;)

Re: MLlib seems to be old (searching replacement)

iSubaru — Thu, 22 Jul 2010 21:09:03 +0200

Explain please a little more that sprite.currentFrame = X; thing :)

The second part was a plan to make initial board as background and then create sprites on top of it then delete them, but there seems to be no delete sprite function or I have missed it
Anyway try it out and You will know what I mean more or less

[wiibrew.org]

Mwehehehe :D

Enjoy

MLlib supports only MOD and MP3 right now, but it shouldn't be hard to support XM. ;)

Re: MLlib seems to be old (searching replacement)

Oh well I don't mind 24bits PNG files, for now they won't take all memory...and probably long time it won't change teehee
Add to the list...like editing this page You have linked and adding? Somehow I find some instructions on Wiibrew difficult to understand...dunno why

BTW Minishlink does MLlib allows to load also XM files or just MOD ones? If that's only for MOD for now...hmm I will have to use detour :P
Loading tracker music is diffrent in DS so I'm little confused by lines in "mod from buffer" example because it looks like only MOD files can be loaded
In other hand it would be odd that You can load MOD files but can't XM ones...especially with hardware Wii has

how to make it possible be downloadable by Homebrew Browser? Is there some thing that must be sent to someone for acceptation, or maybe they do it automatically?

Simply add it to the list: [wiibrew.org]

iSubaru — Tue, 13 Jul 2010 16:47:49 +0200

Ah...so that's why...well I have habit to convert to 256colors because of DS programming, I had no idea that Wii preffers no-pallete way
Oh well one sec I will try it on, I hope it will finally kill sprites problem and I will be able to return to old code again...which went missing somewhere in hell I bet...heh

...
Guess what, it loaded it properly :D
Thank You million times
I can finally return to coding...finally...OK first of all will be rewrite small game and release it on Wiibrew...
BTW if I may ask here (to not make thousand topics for single things)
Let's say I have released homebrew game, did added it more or less to wiibrew as wiki page so everybody can download it...how to make it possible be downloadable by Homebrew Browser? Is there some thing that must be sent to someone for acceptation, or maybe they do it automatically?

If you want warnings like that when converting your images, instead of raw2c, you may want to use WiiBuilder.

Re: MLlib seems to be old (searching replacement)

iSubaru — Tue, 13 Jul 2010 13:32:25 +0200

I have found out something, the thing that is broken are sprites itself...but I do not know what can be wrong, I will post information about all three sprites I tried to load

nothing.png 320 bytes 256colors PNG format 64x64 pixels
O.png 547 bytes 256colors PNG format 64x64 pixels
X.png 580 bytes 256colors PNG format 64x64 pixels

What can be wrong in them o_O
Minishlink.png in example loads correctly in Wii and it has 100x100 pixels, what is connection between them?
I don't recall some speciall requirements for sprites not counting that size must be multiple of 2...and 64 IS multiple of 2...so what the heck :(

Thank You for advance

Sorry for long delay
Finally vacations time and I can code at 200% enhancements
I have installed about 1,5 month ago new Fedora release, recopied whole devkitpro bargain (bargain ahaha) and tried compiling two examples from MLlib...guess what, they compiled (MP3 from buffer and MOD from buffer), also I have sent them through wiiload (which I had suspection may be failing part as well) but...they worked without errors...I feel shame, it all goes to the point that I made some funny mistakes in coding that caused Code Dumps...but that part will be checked in a minute or two, I must check if I still have that source code or not :P

End of report

iSubaru

EDIT #1
Oh I have noticed that source of MLlib has changes made :) I will read them and update if it will be safe teehee

EDIT #2
I have tried to recompile and run mine code and still code dump...Hmmm I will try grabbing one of examples and add more and more lines from mine code to find out what's making it hang...come on...

Re: MLlib seems to be old (searching replacement)

Minishlink — Sat, 22 May 2010 13:49:03 +0200

It's strange you got code dumps... Did you use TTF fonts ? If so, I can understand. It's the only unstable part of MLlib.

Thanks anyway :)

Re: MLlib seems to be old (searching replacement)

iSubaru — Sat, 22 May 2010 04:04:39 +0200

Well it's not easy to describe problem more detailed then "it starts and bang code dump" if that would be at least in some part with some part working, but no, that's why I felt hopeless, plus last update was about half of year ago without any info so that worked bad on my faith :P
I don't say "throw away school" but at least small note could make things go better because we would all know You still continue project just You are little busy
I can post what I know on codegoogle issue page as said earlier it won't be anything but pure non informing facts and suspects :(

"Since MLlib is an open-source project, everybody can contribute to the project and make it better. But sadly nobody helps."
I'm not that big pro at coding to be able to help in such project, I wish to but I would quicker screw up something than improve :(

Re: MLlib seems to be old (searching replacement)

Minishlink — Thu, 13 May 2010 21:15:32 +0200

If you ever encounter any code dump with my library, email me or post an issue on Google Code... I can't make my lib better or more stable if I have no feedback...
Anyway, next release should be in the first two weeks of July. Sorry if I don't update it regularly but it's not my priority since I have other projects and before everything else: school.

Since MLlib is an open-source project, everybody can contribute to the project and make it better. But sadly nobody helps.

Thanks for the input...I will address these items when I return from vacation.

I am surprised about the black on gray comment...on my monitor the gray is almost white so there is a strong contrast for me but obviously not for all...I will address it. Thanks.

I will also recheck my HTML under Firefox. Under IE8 it seems to work fine without the mentioned display problems...but many people do use Firefox...so I will recheck it with Firefox.

Cool...I wrote it for Windows based PC so I am happy to hear that it can be (apparently failrly easily) ported to Linux.

Well, Visual Basic 6 can be run without much problems because I can put required libraries in program directory or install while Run-Time to Wine as did this time :P
But it's only Studio tested for now, the second part still awaits but if that's like only recompile pseudo code or something like that, then I guess it will go fine too, I try Studio and mess with images, I will check documentation in a minute or two and try to make it more serious heheh :P

You have some HTML problem on your forum, the code for blank space requires a ; at the end, so it's

On Firefox you see: &nbsp2 Posts

I think it's a real bad idea to write black text on a grey background. I just can't read it.

Thanks guys...obviously I am not trapping for the Cancel button on my dialog boxes.

I will fix that as soon as I get back from vaction (approx 2 weeks).

I really appreacite all this bug locating.

Although you might just want to PM, e-mail or IM me (OndrejBlazek [at] MSN [dot] com) with bugs that you find so that we don't over use this forum for software specific issues. I also have a Forum at wiiconstructionset.hopto.org but I have had one report of a user having problems using it. I have tested it myself and I don't see any of the problems that were reported so it might be a browser dependent issue. I used IE8 with JavaScript enabled and it worked fine for me.

Bug in WCS Studio

Crayon — Fri, 30 Apr 2010 06:29:12 +0200

LordAshes, go to Direct C Code, double click on Import File. When the dialog box appears click Cancel. The apps generate an error:

Run-time error '75':

Path/File access error

And when you click OK, it close the software.

EDIT:
When you click on Cancel on any Save or Load dialog box it generate an error.

When You click Sign Up with empty fields it sort of logins to empty account or something
"Welcome back"
But without username typed

Thanks I will look into that. I still need to add a lot of bullet-proofing to the site. Right now it runs okay (as far as I tested) but it still lacks a lot of error checking and bells and whistles. Again, I am waiting to see if I get some users before working on this project because otherwise it would be wasted effort.

I'm middle good at DS programming but still new to Wii programming, it's way diffrent from DS one in many aspects like background and sprites displaying (they had to be in while(1) or they would not appear o_O)
I will try WCS and try to learn for now by myself, I don't want to ruin Your vacations :P it will be nice test for me if I can manage something like GRRLib with WSC ^_^
Have a good time spent and stay safe
Time to coding ;]

No problem...If you are a descent programmer then you probably will not stick to using WCS to make your applications...but as I said, it can be used as an Introduction To GRRLIB Basics. Since the code is commented (including the Pseudo code commands that you add as the user) it will quickly teach you how various things are done in GRRLIB. Then, for the fine details, you can consult the documentation.

BTW, I am going to be on vacation for the next two weeks starting Saturday so I may not be able to answer your questions until I get back...I don't know what my access to internet will be while I am away. The manual that comes in the WCS download should explain most things. Make sure you read the Installation instructions since they are not comepletely straight forward.

Good Luck.

Guess I will try GRRLib then, I don't have much to rewrite since it was on one project beginning per big B and on other was some kind of porting from DS project so nothing lost...oh third project was from a scratch but as well not much coded
I will try WCS too, oh and I will PM You LordAshes if anything will come up about it :)
But first things first, it's late here so no matter what I must get some sleep first to "THINK" efficently tomorrow ^_^ then I will start "fight" with understanding GRRLib a bit...heheh finally Wii Programming resurrection plan

Re: MLlib seems to be old (searching replacement)

LordAshes — Thu, 29 Apr 2010 02:22:00 +0200

I also use GRRLIB and I find it very easy to use if you do not require complex construction. I have used it for all kinds of 2D stuff including displaying backgrounds, displaying sprites, displaying animated sprites. GRRLIB supports transparency although it does not have routines for Fine Collision detection (i.e. checking actual pixels in the images to see if non-tranpsarent pixels have collided) but the routines were not that hard to add using the GRRLIB's GetPixel functions. Feel free to PM me if you would like a copy of my Fine Collision detection routines. GRRLIB also provides easy access to scaling and rotating your images.

Libogc (see the examples for Wii in the DevKitPro directory) has many of the functions that you indicated (MOD player, MP3 player, support for USB keyboard, file acccess to SD, etc).

One way to learn GRRLIB is to read the documentation that comes with the Trunk install. I found this a little dry and in some cases not so informative. What I mean is that it tells you all the data structures and functions that you can call but there seems to be a lack of detailed explanation for some of the function inputs or effects. An alternative way to learn some of the GRRLIB functions is to borrow what others have already discovered. I have a program called Wii Construction Set (not to be confused with Wii Game Studio) which basically allows the user to select images, create objects and use a Pseudo code type of language to create their project (using a graphical GUI environment). Then WCS translates all the Pseudo code into regular c code with full comments. Thus, one way to learn some of the GRRLIB basics, is to create a sample project in WCS and then look at the resulting code to see how it is translated into c code using GRRLIB. You can even use the empty WCS project as a template since it already implements a fairly good object system and routines for handling animation automatically. If you are interested the program is currently in its Alpha Release and can be downloaded from:

[wiiconstructionset.hopto.org]

This is also the location of the forum which you can post WCS related questions/comments. The forum requires registration but it is free registration.

Use GRRLIB. I used MLLib as well and am now migrating to GRRLIB for my applications. I have to rewrite a bunch of things (a sprite/coordinate) mapping system, but GRRLIB offers a benefit of allowing texture composition (essentially texture buffer drawing).
