I think it's time to work on the Techs

[Vehek]

I don't know why I never realized this before. The pointer list is the same one as described here:
http://www.chronocompendium.com/Term/Attacks_/_Tech_Scripts.html
That means what we're doing applies to regular attacks too.

[Vehek]

I've been looking at the character animation of techs (mostly healing techs), and I noticed something.
Several of them start with 7215, while a few start with 720D.

These seem to affect facing. With 720D, the character faces his/her target. And with 7215, the character faces down.

The following is a trace log from me doing Cyclone. It shows it loading data from the ROM concerning ALOT of different areas for the techs, including animation scripts, graphics, etc..


$C1/45BB   BF A6 45 CD   LDA $CD45A6,x[$CD:45AD]   A:0000   X:0007   Y:0002   P:envMxdiZC   

These scripts, for example, start at $CD45A6, and Cyclone begins in this area at [$CD:45AD]
It ends with FF. It  looks like the first byte is the tech, the next 3 bytes determine which graphics get used...

More can be gleamed from this I'm sure.

Animation Scripts
More stuff partially decoded. This won't be all that bad to completely decode.

7A XX - Play sound
20 XX - Wait this long before going on
1E XX - Special sprite movement/animation command (does cyclone's spin and sound, darkens the screen, but not the sword slash graphic that goes with it, among other things)
03 XX - Do an animation
24 XX - Enemy white blink when hit
60 XX - Set Palette (sets palette for the slash sprite of crono's sword)
73 XX XX XX - sword slash sprite, location? X, Y coords from enemy?
35 XX - Set enemy animation

[justin3009]

I've been having trouble with the provoke thing.  I changed the sound and sprites and all, but I can't figure out what byte causes the status ailment.  I'm also trying to see if I can possibly add some Ice Effects to provoke, but so far nothing has worked yet.  I'll probably try to work on this more at home if I have time.

[Vehek]

Try to remember, what we've been editing is animation data for the techs.
Also remember that I mentioned a topic mentioning the locations of tech data when we were first starting to hack the tech animation data.

Anyway, after a little testing most of the bytes were some type of flag that aren't too useful by themselves in the first place.  They're important to the function, but you can't change the function of the tech just by changing the data in this line.  So most of the stuff you can change aren't useful yet.  Maybe you can figure it out a bit better.

Cyclone is on C234B-C2356.  The attack power is located on the 10th byte, or C2354 for Cyclone. 

If it's an attacking tech that is.

If it's a healing tech, the "attack power" or maybe I should say "heal power" is located on the 2nd byte.

Then Slash starts on C2357 and I'm sure you can figure out the rest from there.

He's using headered offsets, so Cyclone starts at C214B in an unheadered rom. He mentioned in another post that each tech is 12 bytes.
I did some testing, and the byte that causes the Confuse status in Provoke is at C21B9.

[justin3009]

Ahhh!  Thank you so much

[justin3009]

Double post but anyways.  I was experimenting with techs and so far, I replaced Lightning 1 with Ice 1, but the graphics of Ice do not show.  I'm guessing their's a pointer that tells which graphics to use for each tech.  Any idea how to find them?

Edit: Here's the video.
Edit 2: Apparently from what i've checked, each tech has it's own length.  Ice was 221, while Leap Slash has like 80 something.  Kinda strange...I'll have to double check to reconfirm it.
Edit3: Any idea where the Techs start in the pre-release?  I need it in order to test something with Magus.

[attachment deleted by admin]

[Vehek]

Which tech data?
Animation data or stats?

[justin3009]

Idk if it is seperate but the graphics for the tech?  Like, I changed Lightning to Ice but the Lightning Graphics sitll show.  Which part of the data controls which graphics should show up on the tech?  Cause I'm trying to do a COMPLETE swap of the tech but it's just the graphics that aren't changing.

[justin3009]

Ok, from what i've seen on the techs.

90-99 is the first byte of each tech and is the thing that tells who does what.  If you change it to 0-10 I believe it's first character slot, 20-40 2nd character, 50-70 is the monster, 80-99 is whoever is using the tech.

On some other bytes A0-AF usually is the fading of the screen.  After the first bytes, some of the numbers usually with 1a or 3a or sometimes just a random numeral are the timing, or the palette of the tech that's going on.

For example, here's Ice's data (552 Bytes Long) I think it's this size...

Now for the first Row:

90 - Represents which character does what.  00-10 No one 20-30 1st slot 40-60 2nd Slot 80 - Broken 90 - Whoever uses Tech
F0 - Not entirely sure, but I'm guessing this tells the tech whether to start or skip the effects.
11 - Doesn't do anything...Left over byte?
6E - Same as above
49 - How much time before to cast the tech
11 - Where Marle is and is going to go to cast it
52 - Where the enemy is located?
11 - Same as above
BB AA - Nothing
6e - Where the Ice surrounds marle and the palette and if the tech works
11 - same as above
A3 - Where the Ice surrounds Marle Starts
11 - same as above
ba - Unsure, but it won't let tech go on if changed
11 - Same as above
A0 - Nothing
09 - Timer?
52 - Nothing
0D - Same as First Byte
05 - ?
5A - Nothing
02 - Animation Frame for Marle
11 - Animation frame for Marle
24 - Marle's Location when casting
02 - Animation Frame For Marle
02 - End Tech Early?
31 - Animation frame for Marle
24 - Enemies Location
03 - Timer for Ice Block
3d - Where Ice block goes, or whether it cast or not, where monster goes, where marle goes
0C - Who Ice block casts on

Well that covers the first row and the first 2 parts of the 2nd row.  You get the point.  This is the basic data for the techs.

You're a better analyst of data than I'm, but I can't seem to find the hex data you posted in the rom.

[justin3009]

I changed some of it to suit my needs.  So kinda beware of that.  But it was 0e1136 for Ice.

[justin3009]

It seems that I was extremely wrong in my calculations for Ice now that I check it.  It's not 552 it's only 126.

I accidentally added 3 techs together somehow...but apparently, 36 00, 76 00,73 00 are definate pointers to the end of a tech.  And 90-9A are pointers to the beginning of a tech.

[justin3009]

AH HA!  I was wrong about ice being 552.  It's 126 bytes, so that fixes that problem.  And a tiny update!  CRONO NOW CAN USE ICE COMPLETELY WITH GRAPHICS =D!  Video on bottom.

Note: Some stuff is kinda screwed up cause I was messing around with the hex!  But trust me, it's fully operational and techs are now able to be swapped!
