About AllTheMons x Mega Showdown
From ModrinthAlways wanted to play Mega Showdown with AllTheMons? Well that's the version you have been waiting for! PLEASE read the description!
AllTheMons is a collaborative effort from many contributors to add as many Pokemon as possible to Cobblemon. All of the addons below have been modified to ensure that there's no overlap, which prevents game-breaking bugs/crashes you would experience without AllTheMons.
This still requires Mega Showdown - it's an addon for it!
Don't use this together with regular AllTheMons - you use either ATM or ATM x MSD!
Addon & Mod suggestions:
The following addons and mods are personally approved and/or tested my me and my recommendations. They feature full compatibility with AllTheMons x Mega Showdown and might make your game a little bit _cooler!_
Click for Addon & Mod suggestions!
Legendary Monuments
Adds many Structures and Dimensions where legendary Pokémon can be obtained. ATM x MSD automatically disables random legendary spawns from this addon if installed _(only the ones that are obtainable through LM)_
Lost Lore
Adds many Pokémon from the extended canon that is the Anime/Movies, Manga, Side Games and more. Okay it's my own addon so #ad I guess?
Better Caps
Tired of Pikachus flat brim? Better Caps turns his cap into an actual three-dimensional piece of art. Also my addon tbf but I wouldn't have made it if I didn't feel like someone might need it!
How to install:
Generally, most Cobblemon addons that add Pokémon are both data & resource packs in one file, so installing them automatically via the modrinth launcher won't work - You have to do it manually. Please follow the instructions below to make sure ATM x MSD is properly installed and can function as intended!
Click for instructions!
Singleplayer:
Put the .zip in /saves/[WORLDNAME]/datapacks _not /datapacks_ Put the .zip in /resourcepacks Enable in game ESC - Options - Resource Packs
Servers:
Put the .zip in /world/datapacks _Sometimes it's called myworld, or something similar, sometimes it has a name instead_ _If you're in doubt about the correct folder, consult your server providers guide on how to add datapacks_
Every Player has to have the .zip installed as a Resource Pack _Best option if for them to have it installed and enabled in their clients_ _It's possible to add them to server resources, but note that there have been issues with this for some cobblemon addons, so try whatever method suits you better_
What does ATM x MSD include?:
Adds missing Pokémon to expand Cobblemon to 1022/1025 Pokémon! Overrides models from Mega Showdown & Cobblemon to provide better ones Adds tons of animations & quirks to existing Cobblemon models All of them are obtainable in survival without compromises! Fixed & added most Pokédex entries and descriptions Adds all missing recipes from Mega Showdown Riding support for lots of the added Pokémon Somewhat lore accurate spawn locations
