Every NPCs get damage

AsoStrife

Hello, I noticed that if I create an NPC using theevents class, it takes damage when I attack it.

I haven't found any parameter to make it invulnerable, so what happens is that if I strike an NPC from a village it eventually dies. Is there no parameter provided by the library to make an NPC untouchable?

Wouldn't it be more convenient to divide it into different folders: NPCs, monsters, and events?

Hello,

Is there no parameter provided by the library to make an NPC untouchable?

class GhostEvent extends RpgEvent {
    isMonster = true
}

Then, if you retrieve the event from the map, you'll know whether it's a monster or not.

// You can retrieve the event in a hook beforehand
if (event.isMonster) {
     event.hp -= 100
}

Wouldn't it be more convenient to divide it into different folders: NPCs, monsters, and events?

You can:

- events
     - monsters
     - npcs
     - misc

You are free to structure the events to suit your project

So your proposal is a custom solution

class GhostEvent extends RpgEvent {
    isMonster = true
}

// You can retrieve the event in a hook beforehand
if (event.isMonster) {
     event.hp -= 100
}

And also the damage is hardcoded and not calculated by the user stats?
It seems a bit inconvenient to have to manage all the npc's like this.
Also because without this if the npc's take damage anyway, since they don't have this subtraction for now

Hmm, you're free to do the math yourself 🙂.

After that, you can use the RPGJS damage system:

event.applyDamage(attackerPlayer)

You can use inheritance to centralize logic


class NpcEvent extends RpgEvent {
     isNpc = true
}

class CharaEvent extends NpcEvent {

}

Here, there's not any hooks to identify whenever an event is fighting or getting damage.

Where should I put the math logic?

No, but you can retrieve events in various ways on the map 🙂

If it's for a fight, the most common way is to use createMovingHitbox on the map,

This creates a temporary hitbox (which can move) and retrieves characters that collide with it. In this way, you can recover events and inflict damage.

Where should I put the math logic?

https://docs.rpgjs.dev/api/RpgServer.html#damageformulas

With the current structure:

In main/server.ts

import { RpgServerEngine } from "@rpgjs/server"

export default {
    onStart(server: RpgServerEngine) {
        server.damageFormulas = {
            // ... math logic
        }
    }
}

Example (current logic): https://github.com/RSamaium/RPG-JS/blob/v4/packages/server/src/presets/index.ts
