# Step 3b. Create several attached maps in one world

# Prerequisites

  • Have version 3.0.0-beta.8+
  • Use Tiled Map Editor, and mainly the World tool

# Why ?

The interest is to teleport the player on an adjacent map on consistent X and Y positions. You can also use a hook to tell if the player can change map or not

# Preparing the world in the editor

Click on World > New World and add a file ending with the extension .world in

create world

Next, add maps to the world

add in world

  1. Click on World Tool
  2. Add the current map to a loaded

Place the maps so that the edges are touching

tiled world

# Add the world to your game

In src/modules/main/server/index.ts :

import { RpgServer, RpgModule } from '@rpgjs/server'
import myworld from './maps/tmx/myworld.world'

@RpgModule<RpgServer>({
    worldMaps: [
        myworld
    ]
})
export default class RpgServerEngine { }

TIP

The world creates maps automatically and the map ID will be the file name. Be aware that if you already have a map with the same ID, the world will use this map

TIP

To quickly add a sound, add a personality property to the map (in Tiled Map Editor) named sounds. Put the sound ID of the resource, client side (see Create Sound)

# Bonus. Prevent map change

There are several reasons for this. For example,

  1. you can check that the character is on a dirt road (by looking at the tile ID)
  2. You can make a scenario, if the player doesn't have the level, he can't change the map,
  3. etc.

Go to and add canChangeMap() hook

import { RpgPlayer, RpgPlayerHooks, RpgClassMap, RpgMap } from '@rpgjs/server'

export const player: RpgPlayerHooks = {
    // others hooks here...
    async canChangeMap(player: RpgPlayer, nextMap: RpgClassMap<RpgMap>): Promise<boolean> {
        if (nextMap.id == '<id of next map here>' && player.level < 10) {
            await player.showText('You can\'t go in that direction yet. You must have level 10 minimum!')
            return false
        }
        return true
    }
}

Note that nextMap is not of type RpgMap because it is not loaded yet. It's only the class, so you can't get everything from it, e.g. the data of the next map
