The Follow Me Script

[EdensElite]

Wait, did I actually make a relevant discovery xD

Yeah, I thought the main troubles would be that the trainer would be static (This isn't a problem for the pokemon as it has two frames bobbing up and down, you would just need to extend the amount of frames) and the event that would bring the pokemon into the game, as surfing requires manual interaction. If you could bypass this somehow so that it does it automatically or perhaps the event could be actually clicking on a pikachu ball at the start of the game and from then on the event wouldn't end. It is a problem :L

[knizz]

This patch will allow npcs that use the 'imitate player' mode to walk through other npcs when their trainer-byte is set to 8.

Guess why this is relevant.

Because...you found out how to create an OAM via map loading routine?

Are you aware that 5 hours of hard work were necessary to make this possible? The whole hack is RAW HEX. It's not even ASM.
EDIT: Not the whole patch. That took even longer. I meant that it took that many hours to allow the follower to walkthrough the NPC and the other way round.

I don't know if this is actually useful, but in ruby the bytes that change when buttons are pressed are at 4000130 and 4000131. For example if I pressed up it would put BF at 4000130 and 03 at 4000131. Down would be 7F at 4000130 and 03 at 4000131. Left would be DF at 4000130, and right would be EF at 4000130. From what I can tell, 4000131 is used for "A" and "B", but not much else. I tried to use this to get a script to work on ruby but it failed misserably. This was meant to start when the player was standing on top of the person following.

Wow!
Alot of effort musta gone into to that there.
Just wondering but would the follower still be with you if you were to enter a building ... or will the dissappear.

[colcolstyles]

It's pretty glitchy but congratulations on getting the map switching to work. Nice job. :)

[Darthatron]

All those glitches are fixed now. The only problem I'm having now is with ledges...

[knizz]

Put the modified source into my Dropbox. Or do you not have write-access?

Done.

Ledge problems. I have some ideas, but they are tedious...

[Chimchar 9]

Now, that's very impressive! Would there possibly be an option to make it disappear or reappear? Or even change it's sprite?

[diegoisawesome]

To Darthatron: It's almost perfect! Nice job!
I wonder if Jambo51 could help with the ledge bit.

From what I just heard, he almost has it solved. But, I wonder how it'll work. I hope it is that the following NPC can read tile movements and will read the fact that they must "jump" over a ledge when your sprite stands off to the side.

That would be as simple as copying your own OW into the TILEAREA and setting the NPC's OAM entry to point to your OW in the TILEAREA ( charset, I believe ). I believe FR uses a 'mirror memory' -- I would look up 'yet another asm tutorial' by Knizz to figure out how to find where to write your OW pixels to so that it's not automatically over-written by the game's engine.

[EdensElite]

I had a couple of ideas.

Firstly, I have noticed that lake water, reflects the image of those on it, It is similar to the surfing thing, but it might be worth a look into.

Secondly, You have obviously noticed that the height parameters required for the sprite editing is much higher than necessary. For every sprite you could just slot a pikachu behind him? The sides would be a problem though :/

Oh, really? That sounds very positive then. I also hope you figure that problem out.

This idea has been shot down many times. The system we have now works better anyways.

Psh. I doubt I use this anyways. I'm not working on a hack.
I'm just wanting to see it work, do it myself and understand it.
Then move on to the next subject.

[Ash493]

Wow... I simply cannot believe what you guys did.
You are so awesome!
If this were to be perfected then the 3rd gen hacking would advance to the next level.
Thank you for that!

[Jambo51]

I've not done any work on this for a couple of days, but have a look anyway :D

This looks amazing, love how you made her walk all the time.

Did you use ASM for this then? x

[EdensElite]

Oh. I posted before viewing the video, this is getting really awesome! Are you going to release the data for this when it has been perfected? and if so how, like a patch or something?

p.s Is that a Genesect cry at about 30 second 0.o?

Very awesome. Just wanted to say great work.
It would be a great present if the code was ever released to the public.

[Ash493]

Awesome, plain awesomeness... =)
Just like the posters above I'd really love to see this feature in a patch so we could use it in our hacks :D
