Navi's Actor Constants

[Airikita]

This is in regards to getting Unicat working... I've been looking at Navi's header, and I need to know something about it:

 

Navi: 0018 0700 0200 0030 0001 0000 0000 02D0

 

I know 0018 is the actor number, and 0001 is her group... but what of 0700, 0200, and 0030?

 

In the Anubice, we can see this:

00E0 0500 0000 0015 00D6 0000 0000 0314

 

Epona:

0014 0100 0000 0010 001A 0000 0000 03FC

 

In Spinout's wiki, I quote: "Now, I'm not completely sure what this all is, but I do know that the first halfword (0x0002) is the actor number. The upper byte of the second half word (0x05) determines actor category. The fith halfword (0x0032) is the object number." http://http://wiki.spinout182.com/w/Actor_format

 

I would like to know what the filler is, because it seems 0500 means something, and Navi has 0200 while other actors have 0000 in that spot. Any thoughts on this?

There's a little information on the actor header here: http://vg64tools.googlecode.com/svn/n64/z_snippets/actor.h

Look at the MK_AHEAD macro.

 

Also, it would be good to see how MK_AHEAD is used in these custom/rewritten actors...

Well maybe... but any idea why an actor that uses group 0001 (gameplay_keep) would not use another group number? Navi is removed before her code is invoked, which leads me to believe there's some check I'm not aware of.

I find it intresting that the example you picked are all spawned by other actors.

 

Link spawns navi, and can spawn epona.  Anubice, is made up of two actors, and one spawns the other.

 

Just like how Jabu Jabu spawns spawns with own mouth, making it appear like there are two jabu jabu's loaded.

 

No, I can't let help, but thought that to be a strange co-incide-ence.

I need to investigate further into it. That's what I can tell about the format by now:
 
aaaa bb00 ccdd eeff gggg 0000 0000 hhhh
 
a = Actor Number
b = Actor Category

c = Not sure, seen it as 02 in Navi, Din's Fire and Fire Arrow so far. Maybe something about being spawned by Link.

d = Value 80 in Cuccos, Gray Boulders and Pots. All actors you can grab.

e = 04 in Like Likes, 10 in Poes, 50 in Keese and Guays (something about flying?).

f = Varies between 05, 15 and 35 between most enemies. 10 for some actors like the Spirit Temple Shuffling Climb, Cuccos, Master Sword, Din's Fire... couldn't trace a connection. Cows have it as 09. Probably there is more than one value here broken between the bits.

g = Object Number

h = No idea too. Also, should be more than one value, broken in bits. All of them have the last half-byte being 0,4,8 or C.

 

There's some old info from Three Pendants that changing eeff to 019C will make enemies invisible unless you use Lens of Truth.

Wait... I see 03 = bomb... does that mean what I apply it to makes it explode? lol. But yeah, looks like some values seem to be referenced to Link spawning them...

 

Also, good to know to make Gohma an enemy instead of a boss, and some other things.
