This is the kernel for the P2PMMO game: Proof of Honor.

The core is transaction-based and headless meaning that you can send your action-blocks to a buddy and a perfect copy of your character appears in their world.

• it's written ontop of pico
• can use hyperswarm for multiplay
• is totally missing an UI - Please PR/or Issue if you build one!

Once every 24 hours a Hero may
append 1 block of actions - each block
must end with either going to sleep at a tavern or death.

Initialize kernel and create a new character:

import { boot } from 'poh'

const kernel = await boot()

const name = 'Duncan the peerless'
const memo = '<Last words on death>'

await kernel.createHero(name, memo)


// character sheet is exposed as a reactive-store

const unsub = kernel.$player(hero => {
    console.log('current stats and inventory', hero)
})
unsub()

Now that you have a kernel and a hero, you can begin exploring,
maybe visit the town for some shopping:

import {
I, // Items
A  // Areas
} from 'poh/db'

const session = await kernel.beginPVE()

// walk to town
await session.travelTo(A.crossroads)
await session.travelTo(A.town)

// Buy a dagger
await session.interact(0, 'buy', I.dagger, 1)

// Check inventory
kernel.$player(h => console.log('Inventory', h.inventory))()

// Equip the weapon
await session.use(I.dagger)

Good, now we're ready for adventure!

// walk back to crossroads
await session.travelTo(A.crossroads)

// look for trouble
const encounter = await session.explore(0)
console.log('You encountered', encounter)

If a the encounter is hostile, you'll be locked in session.state == 'battle'\ at which point you are forced to choose one of the following:

// Hit the critter
result = session.doBattle('attack')

// Use a skill/spell
result = session.doBattle('cast', 'firebolt')

// Attempt escape
result = session.doBattle('run')

Note: Each round you're allowed to use 1 item session.use(I.herb) before you commit your combat action via session.doBattle()

Once you're happy with your achievements it's time to save state and call it a day:

// goto area with tavern/bed
await session.travelTo(A.town)

// sleep

const [diff] = await kernel.commitPVE()

console.log('gold, xp and stats gained', diff)

note: k.commitPVE() broadcasts your character to the network
if kernel was booted with swarm K = await boot(Hyperswarm)

Ok that's pretty much the gist of it;
But always keep an eye on:

kernel.$player(hero =>
  console.log('current exhaustion', hero.exhaustion)
)()

because:

exhaustion > 1024 = DEATH
