LightHitPoint.lua: HealthPoint's modern cousin.

Made in a few hours. Definitely improveable and not too customizable at the moment.

How to use:
Load the library and it works by default!
Syke! Nothing is preset. You have to register the HP yourself at the moment.
In the future I want it to work with the health variable in NPC config, but that's for basegame.

Customization options:
lhp.iFrames: Unified amount of invulnerability frames across all IDs (25 by default)
lhp.setHarmtypeDamage(Harmtype, value): Sets damage multiplier for specific harm types.
lhp.setHarmtypeSound(Harmtype, value): Sets sound effect for harm types. By default, onNPCHarm cancelling also cancels the SFX, so this adds that back in.
lhp.setNPCDamage(NPCID, value): Sets damage which a specific NPC does when it's determined to be the NPC causing the damage. Stuff like fireballs, hammers, etc...
lhp.setHP(NPCID, value): Sets HP for a specific ID of NPC.
lhp.drawHPBar(npc) draws the HP bar and can be overridden in user code
lhp.registerCallback(npcID, func) lets you register an onHarm callback for a given NPC ID.
The onHarm overload is as follows:
harmFunction(npc, harmReason, culprit, currentHP, damage)
if the harm function returns something, it must be a number. This number will override the damage dealt to the NPC. If nothing is returned, damage is not altered. Return 0 to cancel any damage being dealt.

The HP bar will empty before "vanilla hp" is touched, so it can be considered to be something more akin to armour.
Have fun!

Can you please make an example level?

It wouldn't contain any information not already present in the first post. I don't think it would help you if you cannot apply the customization options above.
Like you load the library and then set the damages. If you explain what part is difficult maybe I can help explain that in more detail.
If you could share what you have tried so far that would also help.

(sorry for bad grammar)

The installation is exactly the same as with any other library. Drop it in the level folder and load it with require into a variable.
local lhp = require("lighthitpoint")
And then you just access the fields of lhp for customization.

where do i put local lhp = require("lighthitpoint")
(im kinda stupid)

Your luna.lua file which is in the episode folder if you want it to run in every level, and in a level's level folder if you only want it to run in a single level. All this info is on the wiki and in the video tutorials, for reference.

May I build on this to create a very different module?

Updated the library:
lhp.drawHPBar(npc) is now an exposed function and can be overridden in user code
lhp.registerCallback(npcID, func) is a new function that lets you register an onHarm callback for a given NPC ID.
The onHarm overload is as follows:
harmFunction(npc, harmReason, culprit, currentHP, damage)

if the harm function returns something, it must be a number. This number will override the damage dealt to the NPC. If nothing is returned, damage is not altered. Return 0 to cancel any damage being dealt.
