Code: Ability Resource Thread

[ShyRayq]

hello. i just wanna ask how to properly implement a new ability.

i'm kind of new to asm hacking and so far i think i'm doing well (just a thought, though)
i successfully added some into my rom like the BW2 Repel system, gain-exp-on-catch, fix sturdy, color codes on nature and IV indicator. since i've done it pretty well i just thought maybe i'd try adding a new ability.

the ability i was trying to add is this protean:

because greninja is a thing, but whenever i tried to use it on battle, it doesn't work.

now the problem is, when i paste this ( 00 49 08 47 01 7B 77 08 ) to 1D7D8 (as instructed) nothing happens. i tried to not to add 1 on the "00" (last) part of the hex where i insert the asm but the screen just stuck after an attack. then i even tried not to reverse the hex and it called a rain, then crash >___<

the part (offset?) where i inserted the asm was on 777B00. i can't really figure out where did i got it wrong, but i really want to learn how to add it because it's a good feature. i hope someone could tell me my mistake. and lastly, sorry for a long reply, plus the bad english since it's not my mother language.

ps: i'm using mrds patch

Okay, I'm not really good at ASM, but I picked up a few things.
1st, in the ASM code, there is a section near the start called 'Proteancheck'.
In this section there's a bit of code that says:
cmp r0, #0xA9.
The A9 represents the index for the ability Protean in the table of abilities. This will not be exactly the same as in your rom. Assuming this is the only ability you have added, it should be 0x4E.
If you have added more, then it should be 0x4D + NN + 0x01 where NN is the number of abilities you have added before protean in hex.

2nd, I believe there is a string that prints that the user has changed type that you have to insert as well, but I'm not entirely sure.

i see. so it's a lot more complicated than i thought. thanks for telling me. ill try it again and see if ill be able to do it. thanks for the tips!

Is there a routine for Multitype and Judgement around? I think there's an Arceus form change somewhere but I'd like to know if anyone has a fully working version of him, as he should be, Judgement and all.

Excuse me. But any of this abilities have porting to Pokemon Ruby?

Here's Snow Warning for Fire Red! I'll update this and port it to Emerald. I'm going to edit it slightly in the future to account for the new weather abilities too that Kleenex has already written routines for.

Hello I tried editing the Snow warning Routine in your Rom Base which is located at 0x8909990

08 78 2D 28 01 D1 10 4A 10 47 6F 28 01 D0 0F 4C 20 47 0F 4A 11 88 80 20 08
40 00 28 01 D0 00 F0 0D F8 80 20 10 80 0B 4A 00 20 10 70 0A 48 00 F0 07 F8
0A 48 51 46 C1 75 00 F0 04 F8 08 4C 20 47 08 4A 10 47 08 48 00 47 AD A2 01
08 49 A1 01 08 1C 3F 02 02 48 3F 02 02 D0 9A 90 08 C4 3F 02 02 AB BB 01 08 
25 BC 01 08 5B BB 01 08

I added 8B 28 03 D0 which adds these lines

	cmp r0, #0x8B @8B is the index ID of Snow Warning Duplicate
	beq SnowWarning

so the code is now:

08 78 2D 28 01 D1 10 4A 10 47 6F 28 01 D0 [B]8B 28 03 D0[/B] 0F 4C 20 47 0F 
4A 11 88 80 20 08 40 00 28 01 D0 00 F0 0D F8 80 20 10 80 0B 4A 00 20 10 70 
0A 48 00 F0 07 F8 0A 48 51 46 C1 75 00 F0 04 F8 08 4C 20 47 08 4A 10 47 08 
48 00 47 AD A2 01 08 49 A1 01 08 1C 3F 02 02 48 3F 02 02 D0 9A 90 08 C4 3F 
02 02 AB BB 01 08 25 BC 01 08 5B BB 01 08

I gave Chirpich (my ideamon) an Ability Snow Warning and Draciate(Don't mind the Draciate name, that's not its effect, just for a test) and capture two Chirpichs with Snow Warning and Draciate Ability. However, instead of "Chirpich's Snow Warning made it hail!", the text appears as "Chirpich's Draciate made it hail!" even though that Chirpich has Snow Warning Ability.

I provided 2 videos below.
The first one shows the success of Draciate but the second one fails.





Can anyone here help me with this?

There was a report mentioning problems with the Magic Bounce Ability in MrDS's Rombase, so I decided it to implement this myself from scratch, and it is working fine in Trainer Battles and Doubles.
Here it is posted with Moxie.

Notes to understand this:

Spoiler:

+ If for some stupid reason, Magic Coat is used on a Magic Bounce pokemon, then Magic coat activates before Magic bounce.
+ Magic Bounce does not activate, if the mon with Magic Bounce is in a semi-invulnerable state (fly, dive etc.).
+ Added a special Flag to ensure that Magic Bounce does not re-reflect a move reflected by Magic Bounce/Magic Coat. Otherwise, a infinite ping-pong loop happens between two Magic Bounce pokemon.
+ A free RAM location is used for this Flag. Initially, it is set to 0. When the condition for Magic Coat or Magic Bounce is met, it is set to 1 (e.g, always the case in singles, reflected spore in doubles) or 2 (e.g reflected growl in doubles), according to the no. of mons the rebounded Move can affect, and then the Rebound is executed.
+ If the value of the Flag is non-zero, the Magic Bounce and Magic Coat checks are automatically skipped to avoid the re-reflection situation and the Flag is decremented by 1 and this Step is repeated until the Flag is cleared to 0.
+ This to try to ensure that during the Rebound itself, the Flag is successfully cleared to 0.
+ The free RAM location refered in the 3 routines MUST BE SAME.
+ Will port to Emerald soon.

Also, these require Jambo's Callasm and Setword commands, and his Battle String Loader Hack.

I expanded the table...
I think it has f7(starting from 00) commands.... so I inserted the jambo's callasm at f8 and setword command at f9 is it ok ????
also

what about that underlined 9A
do it needs to be changed or is something special there ???

Yes, its good to go.
9A is the ability index for moxie. So if you have an index other than 9A for moxie then you will have to change this.

THANKS for the reply :)

Respect and appreciate your help!!!

Thanks again :)

Sorry for my ignorance but I wanted to know if it has already opened a new post for the 7th skills, if I am annoying sorry, it is not my intention.

 

[PufferJumps]

To start off here are a few damage-calc related abilities as well as an update Sturdy effect!

These abilities require Doesnt's PSS Split, because of a few shifting bytes.

.SlowStartLoc is a free ram location that you can use to have the counter for slow start.

It has come to my attention that Technician can apply some unwanted boosts to Revenge and a few other moves, so the code will be amended in the future.

Help!
I really want to add protean to fire red.
Sorry i'm bad at this stuff and i need an easy tutorial for beginners like me.

 

[VeryBestRogue]

Hey guys! I am finding it hard to insert the abilities in my ROM is there any one who could be willing to help out? I expand the Ability Table and then insert the ASM then what do i Have to do ??? I dont want to rely on MrDs' Patch (no offence) as it is not dynamic...

insert the asm routines and make the necessary byte changes, and all should be outlined in the post :P

edit: and mrds' patch is rather fine to use unless if you're using that space starting at 0x900000

Having a problem with this one - all multi-hit moves are hitting five times 100% of the time, even if the user does not have Skill Link. I figured maybe the 5D in the first script was just taken from the "default" index for Skill Link, and I changed that to the index of what it is in my hack, but no dice. Is there something else I need to do?

EDIT: Nevermind!! What I had accidentally done was, when replacing the pointers, I replaced the one in the second script by mistake. Working fine now.

There was a report mentioning problems with the Magic Bounce Ability in MrDS's Rombase, so I decided it to implement this myself from scratch, and it is working fine in Trainer Battles and Doubles.
Here it is posted with Moxie.

+ Added a special Flag to ensure that Magic Bounce does not re-reflect a move reflected by Magic Bounce/Magic Coat. Otherwise, a infinite ping-pong loop happens between two Magic Bounce pokemon.
+ A free RAM location is used for this Flag. Initially, it is set to 0. When the condition for Magic Coat or Magic Bounce is met, it is set to 1 (e.g, always the case in singles, reflected spore in doubles) or 2 (e.g reflected growl in doubles), according to the no. of mons the rebounded Move can affect, and then the Rebound is executed.
+ If the value of the Flag is non-zero, the Magic Bounce and Magic Coat checks are automatically skipped to avoid the re-reflection situation and the Flag is decremented by 1 and this Step is repeated until the Flag is cleared to 0.
+ This to try to ensure that during the Rebound itself, the Flag is successfully cleared to 0.
+ The free RAM location refered in the 3 routines MUST BE SAME.
+ Will port to Emerald soon.

Also, these require Jambo's Callasm and Setword commands, and his Battle String Loader Hack.

Not sure why I am having a tough time getting Moxie to work. When I KO a pokemon in the wild the attack boost animation plays then the game gets stuck there.

I put the pointer to where I inserted script XXXXXX at 0x08213DC;
changed the ability index to 4E from 9A since I only added Moxie;
added callasm to the command table at F8;
added battle string loader exactly as Jambo posted it here https://www.pokecommunity.com/showpost.php?p=7101031&postcount=230 do I need to change it at all?;
added setword command KDS posted on page 3 and added a pointer to it at FA in the command table.

What could be wrong?

Edit: For Fire Red
