Emulated Rebornian/Rejuvenian Field Effects & Revamped Battle Tower (v3.0.0b) [v21.1] (Updated 1/18/2025)

[DarkWolf13]

I hope I am doing this right... but I after working hard on this. I am proud to announce that I present you the Rebornian/Rejuvenanian Field Effects for v21.1.
Here are some of the screenshots I've taken the liberty to share. No, I'm not Edd from Ed, Edd n Eddy for those who know what he says.

These fields that originate in Pokémon Reborn and Pokémon Rejuvenation can definitely alter how you and your opponent will take victory! Take advantage of the fields to your best advantage.
Not only did I bring field effects but a myriad of additions/changes.

• EV Limit is removed. You can have 252 EVs in every stat.
• Rivalry no longer reduces damage on a target of the opposite gender.
• Item BP Shop
• New item known as the Technical Charm, which grants the holder the effects of Technician.
• Field Seeds (Elemental, Magical, Synthetic and Telluric) are added.
• Frostbite and Drowsy from PLA take the place of Freeze and Sleep respectively.
• Hailstorm takes the place of snow. Weather damage from hail and Defense boost for Ice-types in snow are combined together into one weather.

Now as far as Field Effects go, I was able to emulate most if not all of them so the fields operate almost the same way. However, here's what makes them different from their games of origin.

• The fields cannot be terminated or changed by moves by any means.
• Steel Roller is usable on ALL Fields. It hits at full power on overlayed fields while terminating them but has a reduced power of 90 otherwise.
• Ice Spinner only destroys overlayed fields. Meaning it can destroy Electric Terrain that overlayed the City Field but it can't destroy a perma-set Electric Terrain.
• Sub-types ignore type immunities and abilities. E.G. A Dragon-type move can't hit Fairy-type Pokémon but a non-Dragon-type move with a Dragon sub-type can. And hitting a Justified Pokémon with a non-Dark type move with a Dark sub-typing will not trigger the ability.
• Concert & Flower Garden Fields are one-stage only like all other fields. As a result their effects were modified. Check the Field Effect Notes .txt for info.

While this has modified script, this project has also utilized plugins that were also modified. These are the plugins that are included with this project albeit modified from the original.

• Generation 9 Pack Scripts
• v21.1 Hotfixes
• Deluxe Battle Kit
• DBK Plugins (Enhanced Battle UI, Terastallization, Animated Pokémon)
• Ultimate Move Tutor (Added for v2.0.0b)

Spoiler: Changelog

2.1.0b:

• Installed the latest versions of the Deluxe Battle Kit & Add-Ons
• Special Fields Division Battles now available. There is slowdown during the challenge so please give it time. However, these battles are using the default roster for now as the Special Fields rosters are still a WIP.
• Added Master Tera Jewel to the BP Shop.
• Changed the BP payout after 7 battles to be sufficient.

2.0.1b:

• Fixed a bug where Gooey gives an error due to the default Terrain not being added.
• Added the 17 types of Hidden Power to the Move Tutor to freely select your Hidden Power type.
• Added functionality of the Beach Field version of the Shell Bell where the holder recovers 25% of the damage inflicted on the target.

2.0.0b

• Corrosion's bonus effects on Wasteland Field are now blocked by Shield Dust and Covert Cloak.
• Fixed Core Enforcer not having negative priority on Deep Earth Field.
• Planned TM Shop removed in favor of a National Move Relearn NPC. Located on main floor.
• Added new BP Item Shop on the upper level of the Battle Tower.
• Natural Gift no longer uses up the berry, allowing the user to use the move consecutively.
• Pluck & Bug Bite's damage are boosted by 1.5x if the target has a berry.
• Luminous Moss & Absorb Bulb trigger on Water Surface & Underwater Field.
• Snowball triggers on Snowy Mountain Field.
• Pokémon that evolve when traded can also use the Linking Cord. (Part of vanilla Gen 9 Pack Scripts)
• Pokémon that require an item to be held when trading to evolve now can evolve with the Linking Cord as long they have their required item. E.G. Onix needs to be holding a Metal Coat to evolve using the Linking Cord. The item remains on the Pokémon after evolution.
• Snow Cloak & Sand Veil increase the bearer's Sp. Def by 25% instead of evasion.
• Defeatist now reduces the bearer's Attack & Sp. Atk by 25% instead of 50% at half or less HP.
• Added fixes to the AI when Hisuian Decidueye & Hisuian Typhlosion use their signature moves.
• Added fix for Opportunist's message using battler.pbThis instead of user.pbThis.
• Tera Types have been assigned to all of the Battle Tower's Pokémon.
• Meloetta can permanently stay in Pirouette form after using Relic Song. Use the move again to change it back to Aria form if it's in Pirouette form.

• Main floor of the Battle Tower completely changed. Left receptionist is for regular Single, Double and Triple battles. Right receptionist is for Inverse Single, Double or Triple Battles. As such the following rules are applied:
  - Single Battles are 3v3, different Pokémon and items.
  - Double Battles are 4v4, different Pokémon and items.
  - Triple Battles are 6v6, different Pokémon and items.
• Upper Level of the Battle Tower renamed to Special Fields Division. Left receptionist for battles of a field of your choice when she asks you. Each Field has a different roster of Pokémon that benefit from the field with abilities and moves supported. Right receptionist is for Inverse battles with fields excluding the Inverse Field itself. The following rules are applied:
  - Special Field Challenges are 6v6 Doubles or Triples using different Pokémon however you can have 2 or more Pokémon holding the same item.
  - These battles will be available at a later update.
• Move Relearner NPC can universally teach any Pokémon the following moves even if they can't in the main games due to the move either being incompatible or outright removed as a move or a TM:
  - Return, Frustration, Toxic, Natural Gift, Secret Power, Hidden Power, Tera Blast
• Check the movepool additions .txt file for moves Pokémon gained.
• Provided a Natural Gift Berry chart .txt file for list of Berries I recommend using for Natural Gift reasons.

3.0.0b

• All challenges playable. Grassy & Electric Terrain challenges done with updated rosters.
• Underwater Field no longer damages those weak to Water and no longer nerfs non-Water type moves used by non-Water types. Speed reduction remains though.
• Some move changes on the Tower enemy roster were made.

What to expect in a future update:

• More Special Fields Division battles. These are battles using fields you select. Enemy roster WILL be different for each field if not different, different sets.
  - 2 / 48 Challenges fully complete and ready to be played. Other fields use the default roster in the meantime.

My major goal of this project is not only to bring Rebornian/Rejuvenian Field Effects to Essentials v21.1 but to also bring an enjoyable PvE experience in the Battle Tower. As ambitious as it sounds, I am willing to do my duty and provide y'all with the best Battle Tower challenges you can think of. This is what I plan to bring to revamp the Battle Tower:

• Triple Battles with and without Field Effects (Complete)
• Inverse Battles (Fieldless only. Also a special field challenge as a field of its own)
• Heavily revamped enemy roster for every field and the default challenge itself with optimized movesets. (Complete for fieldless)
• Battle Tower will allow ANY Pokémon to be used as the opponents will use Pokémon like Rayquaza, Koraidon, Zacian etc. in later battles. (Complete)
• For Battle Tower challenges involving fields, duplicate items will be allowed. (Complete)

IMPORTANT! You MUST have already downloaded the first link. Second link are the fixes and will be updated accordingly. This is to avoid having to download the whole thing over and over again every time an update comes. Just unzip everything in the main game folder.

Extract the main game in a separate folder. Then extract the fixes in the game's main folder.
Please let me know of any issues so that I can fix them the best I can.
Heads up on this. Debug Mode IS ENABLED BY DEFAULT. So you can freely build your Pokémon teams and use Debug to test the fields for yourselves.
I have provided the .txt files of the Credits and the notes I made regarding the fields so you can study and read up on building teams that revolve around the field.
Enjoy.

hello, can you upload this project to github, i believe it will attract people.

Hi Darkwolf13



I tried out v3.0.0b, the update you made to the Field Effect Project on the 19^{th of} January 2025. I encountered a problem related to the move Bug Bite. When the move is used by the opponent Pokémon, it gives this error message:



[Pokémon Essentials version 21.1]

[v21.1 Hotfixes 1.0.9]



Exception: NoMethodError

Message: undefined method `is_berry?' for nil:NilClass



Backtrace:

This is when I downloaded the latest version of the Field Effect Project, and I did not add any additional plugins. I can't quite tell what's going wrong with the version of Deluxe Battle Kit the download of the Field Effect Project comes with. Because when I change the move properties of Bug Bite in moves.txt, to have None as its function code, meaning it's an ordinary attack move, the game does not throw an error message and soft lock the game repeatedly, until a paralysis check paralyzes the opponent Pokémon. I thought it would be best to alert you to this problem I encountered. I first found out about this problem on the 23^rd of January 2025.

 

[DarkWolf13]

That is strange. I'm doing a test battle with an opposing Pokemon with Bug Bite and the move works as intended. Do you know if this was done in a field? If so, which field was it so I can test. And did you do a fresh download and a fresh restart of a new save? You might need to erase your old save and start anew.

Hi Dark Wolf

This time, I downloaded the source project from here on Poke Community. I cleared out all my save files that were leftovers I overlooked when I was crafting my own build of Essentials. I did a test battle against the Team Rocket Grunt in the stock maps that come with Essentials. When fighting Burmy in a battle with no field effects active, on Route 7 of Essen, the stock region map that comes with Essentials, and it uses Bug Bite. This happens:



I have made zero edits to your Field Effect Project when testing again the Bug Bite crash issue. And this is the PBS data of the fight on Route 7, in a normal trainer battle situation, in a battle with no Field Effects active:



And just like before, if this crash happens and the opponent of player Pokémon using Bug Bite don't get affected by Paralysis, the game soft locks. This issue happened in the exact same way, before I cleared out the possibility of leftover data affecting things. And after clearing out leftover save data.

 

[DarkWolf13]

That is strange... also, those trainers in the Essen route I left untouched because the primary focus of the game itself is the Battle Tower.

I went to that particular trainer and tested it out and had Burmy use Bug Bite on me, and I had Static but I did not get the error.
Edit: AH, I SEE..!! The error occurs AFTER the berry was stolen and eaten and the move was attempted again. That was my doing because I had changed Bug Bite and Pluck to deal extra damage if the target was holding a berry. Thank you for sharing this and I'll see to a quick patch to solve this immediately.

 

[DarkWolf13]

Added a fixes link underneath the main link. Put it into the game's main folder and simply extract and replace all files within it. If you had made any changes prior, BACK UP the folder first.

Added a fix with Bug Bite/Pluck

• Bug Bite and Pluck no longer deal extra damage as it caused a bug when attempting the move again after successfully stealing and eating a held berry.

The fix has been applied. I tested it and it no longer crashes or gives an error when attempting the move again after the berry was stolen and consumed by the move.

I just tested the Fixes Patch for 3.0.0. Bug Bite is working as intended now. The game no longer soft locks when a Pokemon in a regular battle with no field effects use Pluck or Bug Bite. Good job on making the fix!

Kudos for releasing an alternate version of Pokémon Essential 21.1 featuring Pokémon Reborn's Field Effects. I had wondered why so many rebornian fangames were still based on version 17 of Essentials. Does the battle AI in this version take into account all these terrain changes? (I know that at Reborn, their combat AI script is almost 1 Megabyte)

For my part, I entirely coded my Field Effects on my fangame, based on an old version of PSDK.
Here is the full documentation. Maybe it can give you some ideas.

https://www.sacredphoenix.fr/res/Telechargements/PDF/GDD/Field%20Effects_EN.pdf

I have a holistic version of Field effects: so it encompasses weather and other terrain effects that aren't explicitly a battlefield or climate effect.

Thank you. The Battle AI I will have to take a huge look into once I have the Tower rosters in every field challenge ready and set. There are a few glaring issues I have been seeing such as the AI favoring NVE moves at times like Knock Off but maybe cuz it prioritizes slapping down the opponent's item away. Also, 2-two moves ALWAYS targeting the right-most Pokemon in Doubles/Triples like I have a Steelix on the right and the opponent chooses Meteor Beam but targets Steelix, not Steelix's partner who is weak to the move. I would love to find a way to stop that. I don't plan on adding any more fields since it had taken me a few months before finally having all the fields from Reborn/Rejuvenations working (BAR MIRROR FIELD, sorry but a field that encourages accuracy hax is definitely not what I wish to have here.) Plus these fields, as I said in the first post, function different to their games of origin since I don't know how to effectively change the field bgs midbattle, so I chose not to include the transitioning effects and removed field damage overall. This project is still ongoing but going slow since RL stuff and working alone on this.

That's why I shared my own game design, hoping that this can help you complete what you're missing.
I managed to code all the features myself (barring the addition of a second type, as this Pokémon Reborn mechanic was absent from my game design).

BTW, here is the mother script of my Field Effects. (The forum does not allow sending *.rb files, I renamed the extension to *.txt)
You can see it in action by downloading my fangame. (Which will allow you to see the few hundred method calls from the BattleEngine involving the Field Effects). Even if it's not on Pokémon Essentials, on PSDK, it's still Ruby, so the same programming language.
