LifeSteal

A fabric server side implementation of the LifeSteal SMP

Notice for when updating to v2.0.0

There has been alot of changes since v1.2.0 and as a result the config is very different (i only really added stuff)

Also if you want to disable banning of users when they reach 0 health have a look under punishment in the config as it has been moved

Required Mods

This mod is dependent on BFAPI

Commands

This mod adds a command that can be used to modify and get a players lost health, the general structure is as follows:

/alias [get [uuid/name]]/[set [uuid/name] value]

This allows for moderation of players health without lengthy server restarts

The config is found under lifesteal.json in the config directory

Api utilisation

This mod adds a (simple interface)[https://github.com/BradBot1/LifeSteal/blob/master/src/main/java/com/bb1/fabric/lifesteal/LifeStealable.java] for using it as an API, LifeStealable

LifeStealable allows for a mod to get a players lost health and modify it as needed while also allowing it to be implemented on custom entities so that they can be used to gain health on death

Any LifeStealable implementation should always call setLostHealth when ever the health changes

Additions to BFAPI

Marks

LifeSteal adds a customisable set of marks (check the sub marks for individual marks) that default as lifesteal and health

When these marks are applied to an ItemStack and said ItemStack is used the appropriate message is sent to the user:

If the user has more gained health than the limiter allows it will send markOutputFailed elsewise markOutputSuccess will be sent

Recipes

There are now a couple of recipe requirements/results that are added by LifeSteal

Requirements

LifeSteal adds 3 new requirements to custom recipies, these are:

These can be utilised to lock recipes to certain health levels such as losthealth< being set to -2 will only be craftable by those who have gained a heart

Results

LifeSteal adds 3 new results to custom recipies, these are:
