Development: Animated Trainer Sprites in Ruby and Fire Red

[shiny quagsire]

OK, so me and xGGxToiZ have decided to release our knowledge to the general public. This knowledge is the knowledge of trainer animations!

xGGxToiZ noticed the pointer I found to a blank animation while looking at the trainer's back animations (No, this is not the front animations!). Here's the origanal post:

it's at offset 239EBB.There are 6 different trainers: the boy, the girl, trainer dude, old man, brendan, and may. plus, they're all the same!I played with the values, and it's correct. These are the animations for the trainer backsprites! Funny, there are pointers to 2347E8, which contains this:

00 00 00 00 FF FF 00 00

I fiddled with the first value, the frame, and changed it to 05, and check out the result!

Oh, and I was a boy at the time.

It was quite odd, because it also led to the trainer's sprite, and several other things we don't know.

So how do we do this? Simple! Let me quote xGGxTioZ:

Table starts at: 0x238E8C
Select: 250h Bytes. (148d * 4d)

This means, each trainer can have their own number of frames! Exciting, huh? And if we can expand it, who knows what are the possibilities!

So, like he said, each trainer gets it's own animation pointer. So go to the table, and multiply your trainer's sprite's number (Starting from 0) by 4, and add it to the table offset. Now repoint the following pointer to free space, and write out your animation data. Here's how it works:

Animation data is a sequence of 4 bytes, giving data on various information, and ends in FF FF 00 00.

The first byte is the frame number from 0 Up to as many frames as you want!
The second byte is unknown, but I'll look into the ASM coding to figure it out.
The third byte is the duration. 0x10 is about a half second.
The fourth byte is unknown

After you've typed up as many of these sequences you want, end it in FF FF 00 00. Here's one I used for Pokemon Chrome:

00 00 00 00
02 00 FE 00
02 00 30 00
01 00 0F 00
00 00 30 00
FF FF 00 00

I'm not sure why I used the 0's, but it works. This is a good example of going in any order. I went from my 3rd frame, to my second, to my first. The duration of 30 at the end delays when the pokemon are sent out.

I'm not entirely sure about this... This seems to be for trainer backsprites, but all throughout the thread, you mention "trainer sprites"...
Is this for trainer front- or back-sprites?
EDIT: I see. In this thread, there's info on the frames for back sprites AND for front sprites.
Awesome!

It's fro the front sprites. Each sprite has their own pointer in the table at 238E8C

Yeah, I saw. But there's also info for the back sprites, which is cool, too.

Yeah, that was how he found it. It was just actually a post from the pokemon animation thread.

Ahh, I see.
Both are still interesting discoveries, though.

[altariaking]

Yay! I already had the offset for Ruby but it's good to see you've released it to everyone now

[knizz]

Great find! (Why didn't you tell me about this earlier?!)

So... which animation is front and which is back?

I couldn't tell you because I promised xGGxTioZ to keep it a secret. In fact, he posted this video in the pokemon animations thread. (Which he actually made, but he never told anyone that)

Spoiler:

The back animations are at 239EBB, and the front onse are in a table of pointers to each trainer's animation at 238E8C

please How can I animate the pokemon too in fire red ? and where do I put this code ?

If you scrolled down in R&D you'd find it.

I'm using the HEX editor in NSE..I searched the Sprite table and entered this code then the game freeze once I start a wild battle even after I added 2 sprites for the pokemon.

how do I repoint it to another offset ?

[SneakyEpicface11]

Hmm.... seems complicated... that is why I do not do rom hacking xD.

What's the Final Code? I'm using FR and I need 3 frames each for some trainers. I can apply this to whoever I just want animated right?

Um, code? I guess the closest thing we have to code is ASM, but ff you mean hex it's at the bottom of the post.

[hackstar]

Is animated trainer sprite is working?
