Conversion Capers: Rygar

[sandruzzo]

phx told me this:

During the game, whenever you want to play a new mod: call mt_init to prepare the mod for playing at a specific song position. You will pass a pointer to the mod and an optional pointer to the mod's samples (for the usual mods it will be NULL, because samples are directly attached to the patterns in the file).

How can get the pointer to specify sampler?

Updated Version with cut rygars' music.

looks good here, no slowdown with the new monsters and music.
but the new sprites moving down after a while - each time a little bit more.

To play the various subsongs from the module at http://eab.abime.net/showpost.php?p=1102407&postcount=1173 you would simply take the first number mentioned for the subsong ($0B for end stage music, for example) and put that in d0 before calling mt_init. Set a1 to zero unless you've relocated the module's samples somewhere else in memory.

For sound effects, load them somewhere in chipmem and call:

mt_soundfx(a6=CUSTOM, a4=SmallDataBase, a0=SamplePointer, d0=SampleLength, d1=SamplePeriod, d2=SampleVolume)

a0 is of course the location of the sample to be played in memory, d0 is its length (in words, I think), d1 sets the playback speed, try 214 or 428.

I'll check that out

You should, if you like to support later CPUs than 68000.

How can I get AutoVectorBase ?

Check ExecBase.AttnFlags whether you have a 68010 CPU or higher. In this case, read the VBR register in supervisor mode:

        movec   vbr,a0

This is the base address for your interrupt auto vectors. Without it you cannot set new interrupt vectors.

Do not confuse the pointer to the song's samples with your sound effects (inserted by mt_soundfx). For standard MODs you will always call mt_init with a1=NULL, because the song's samples follow directly behind the track data in memory. Their location is calculated by the player automatically.

For mt_soundfx see hukka's reply. Sample length in words is correct. Also make sure that sound effect samples start with two zero bytes (the same is true for the song's samples).

Thanks for alla advice. Vbr is ok, sound play very well! Thanks for you player. After that I'll add sfx

Now rygar can be killed. Still in progress

thanks to the unlimited lives i made it to the temple at the end of the level

you may still get killed, if you run in an exploding enemy, just reporting.

Thanks For this report. I'll fix it

I sent mail to sandruzzo with an updated rygar mod (has death pattern) and converted effects in .raw; however sound FX provided were too much to add even for an empty mod (were around 50, some sound damaged, i converted 40); at this point i can suggest to identify and use only the more essential sfx to use in the game (and in some case recycle)

The sound effects don't need to be inside a .mod, they can be loaded in from separate file(s) and reside anywhere.

Updated Rygar, some nugs gone, better enemy out

new enemies do not shift vertical position anymore.
the blue monsters do not spawn after a short while. maybe there are 8 at the beginning, then they disappear, do not spawn anymore.
just reporting, good work

Thanks, I'll check that out. Bit to bit we'll do a game with good feeling!

yep, it's going that way

bit frustrating dying any second, but works stable.

I'm doing my best...

Updated Rygar. Some small bugs gone. Enemies respawn should be ok

respawn of blue monsters seems ok now. the blue one's do have some kind
of AI, they change direction and hunt rygar. that is

rygar still dies, when he runs into an explosion of a monster.
you have to release the firebutton to turn to the other direction. maybe this is due to my kind of playing, but it feels not right.
just reporting
