A suite of changes for datapack development to extend the limits of what datapacks can do.
Current Features:
- Crit Rework
Makes crits work on any sourced damage, having a multiplier and chance attribute. Replaces the vanilla system. You can enable this feature in the config, it is defaulted off.
- Inflictions
Work like effects but more modular and wide spreading, data driven might be added in the future. Has stack functionality and can deal with multiple sources, and custom combining mechanics.
- Commands
New commands, such as temporary blocks, motion, health, distance, radians from an xy, tick commands, and more.
- Function Tags
New usable function tags like tick and loading for many more purposes.
- Entity death (Occurs before the actual death, so nbt can still be read) [debugthings:entity_die]
- Join (A player can't see messages sent from this event, as they aren't fully in client side) [debugthings:join]
- Respawn [debugthings:respawn]
- Copy Player (Not sure on use case) [debugthings:copy_player]
- Player Dimension Switch [debugthings:player_change_world]
- Attributes
Many new attributes, such as tool level, air speed, positive potion duration, negative potion duration, invulnerability ticks, dodge chance, parry chance and more.
- Effects
Not many are added due to the addition of the infliction system, however there are a few.
- Rubber: Makes things bouncy like slime.
- Wounded: Prevents healing.
- Rot: Lowers max health.
- Temporal Freeze: Freezes the entity completely, preventing most interactions.
- Temporal Stretch: Slows entities tick rate down (does not work on players).
- Temporal Compression: Speeds up entities tick rate (does not work on players).
Removing Potion Recipes
Just because I couldn't find another mod for this feature for this version. Simply add the potion identifier to the list in the config (such as "minecraft:swiftness" or "minecraft:strength_long")
NOTE: Currently it seems modrinth may install the wrong version of additionalentityattributes when installing this mod, so please check
