Where it goes
Where should Effectly be installed in Hytale?
Do not install it as a separate client mod. Enable it on the world host—the local server in singleplayer or the dedicated server in multiplayer.
Put Hytale mods on the world host or dedicated server. Singleplayer runs a local server too; Hytale does not use separate client mods.

About this project
What does Effectly add?
Effectly
Complex Effects made Simple and Universal.
Effectly works as a centralized hub for all multiple mods to list, manage, utilize, or extend the same list of gameplay abilities.
Attribution:
Effectly was forked from the AbilityAPI by Hexvane. It functions as a more performant and extendable not-vibe-coded drop-in replacement. It is 100% backwards compatible with any mod that previously required AbilityAPI
Features
- Enchantable Armor - Add Conditional Effects to armor pieces to give them another level of flair
- Asset-Driven - Making new effects or conditions can be done entirely via the asset editor! Tweaking existing ones can be done just as easily
- Performant - You only pay for what is active. 400 unused effects will have the same performance hit as 1 on your server.
Abilities
- Creative Flight
- Dark Vision
- Fall Damage Immunity
- Health Regen
- Invulnerability
- Item Magnet
- Mining Fortune
- Mining Haste
- Move Speed
- Oxygen
- Unarmed Punch Damage
- Waterbreathing
- Second Change
- Stamina Regen
- Strength
- Swim Speed
- Wall Climb
- Resistance
- Commands
- Drowning
- Elements
- Environments / Environmental
- Fall
- Fire
- Ice
- Void
- Physical
- Poison
- Projectile
- Slashing
- Suffocation
And these are just the defaults! Third-party mods can add more as they need
Enchanting Armor
There are two ways to enchant armor - and for players, no, this is not accessible in survival. This is for mod owners looking to integrate!
#1- Predefined in the Tags
{
"Tags": {
"Effectly:Ability": [
"mining_haste:3:sunlight", // conditionally adds haste 3 when in sunlight
"flight" // adds flight
],
"Effectly:Condition": [
"zone 3" // gates the entire ability behind being in zone 3
]
}
}
This can be done on your item's actual Item JSON file
Or, you can add it via the Asset Editor 
It is also recommended to install Patchly if you are planning on editing existing items.
#2 Item Metadata
Add the object MetaData (i.e. crafting, via code, dynamic per-item abilities for if you want individuality)
"PrimaryOutput": {
"ItemId": "Armor_Iron_Chest",
"Quantity": 1,
"Metadata": {
"Effectly:Abilities": {
"creative_flight": 1.0,
"move_speed": 1.5
},
"Effectly:Conditions": ["zone 3"]
}
},
Enchanting Weapons
Currently disabled for the time being due to performance reasons
While I have the code, I was not happy with the implementation. Waiting on some Hexcode abilities to land before I finish out this implementation because I want to do it right.
Creating/Configuring Abilities or Conditions
New abilities can be configured via the asset editor (or raw json mutation) 
Allowing you full control over what an ability does, how it is configured, and how it behaves. For server owners, this lets you force-disable unwanted abilities, configure power levels, and balance abilities to fit best within your server.
All in all, this was just a fun weekend project! It was sparked from the vibecoded app having performance issues on another server. The Github at the time was licensed CC0 - so I took the liberty of actually doing this idea justice. Please, feel free to reach out to Riprod on discord! I'm most places hytale is.
