wacaine / dclconnect

A utility library for use in Decentraland

dclconnect

Installation

To use any of the helpers provided by the dclconnect utils library

1.) Please install both dclconnect AND the ecs scene utility library

npm install dclconnect@next 
npm install @dcl/ecs-scene-utils

2.) In your tsconfig.json - add a new path that points to BOTH the dclconnect package AND the ecs-scene-utils libraries.

3.) Also be sure to add the include path. You do not need to alter anything else in this file. The code below is what it should look like after a brand new dcl init project is created.

{
  "compilerOptions": {
    "outFile": "./bin/game.js",
    "allowJs": true,
    "strict": true,
    "paths": {
      "dclconnect": [
        "./node_modules/dclconnect/dist/index.d.ts"
      ],
      "@dcl/ecs-scene-utils": [
        "./node_modules/@dcl/ecs-scene-utils/dist/index.d.ts",
      ],
    }
  },
  "include": [
    "src/**/*.ts",
    "./node_modules/@dcl/ecs-scene-utils/dist/index.js",
    "./node_modules/dclconnect/dist/index.js"
  ],
  "extends": "./node_modules/decentraland-ecs/types/tsconfig.json"
}

BoxHighlight

Create New

The BoxHighlight component is a graphical, non-colliding entity that can be used to attract attention to the user. It's used heavily within this package, but it can also be instanced on it's own.

BoxHighlight has three required arguments:

• position: Vector3 for the position
• scale: Vector3 for the scale
• direction: String indicates the direction the effect should face.
• Options: "top" | "bottom" | "north" | "south" | "east" | "west"

Example

import { BoxHighlight } from "dclconnect";

const bh = new BoxHighlight(
    new Vector3(5,2.5,5),
    new Vector3(5,5,5),
    "north"
)

BoxHighlight.(setStripeColor/setSurfaceColor)

You can set the color (and emission) of the stripes/surface with these methods. The color values are generally between 0-1 instead of 0-255. However, if you set any of the red, green, blue values to above 1, it will glow brightly! It looks cool.

bh.setStripeColor(new Color3(1,1,0))
bh.setSurfaceColor(new Color3(0,10,1))

BoxHighlight.(setPosition/setScale)

You can adjust the position, height, width and depth of the BoxHighlight by invoking the following methods. You just need to pass along the x, y, z as parameters.

bh.setPosition(8, 3, 8)
bh.setScale(3, 6, 3)

BoxHighlight.(setDirection)

Indicate the direction that the BoxHighlight effect should point. Options: "top" | "bottom" | "north" | "south" | "east" | "west"

It's not encouraged to rotate a BoxHighlight for a few reasons. In short, this is due to the way that triggers, zones and other internal dcl entities work with collisions. You can technically rotate it, however there will be unintended effects.

bh.setDirection("top")

SplitFlap

Example

import { SplitFlap } from "dclconnect";

// Creates a display that is 11 characters long
const sf = new SplitFlap(11)
sf.setText("Event Soon!")

// Alternatively you can include the initial text in the same command
const sf2 = new SplitFlap(11, "Event Soon!")

// To quickly flip to the text without having to wait for it to cycle
// through all of the characters, you can set the `quick` value to true
const sf2.setText("Event Over!", true)

AudioControlBar

AudioStreams

Please review the official AudioStreams docs for setting up your audio streams properly.

// For AudioStreams
const audioControlBar = new AudioControlBar(new AudioStream(
    "https://ice1.somafm.com/groovesalad-128-mp3"
))

VideoStreams

Please review the official VideoTexture docs for setting up a video screen properly.

// For VideoTextures
const vclip = new VideoClip(
    "https://Somedomain/Video.m3u8"
)
const myVideoTexture = new VideoTexture(vclip)
const audioControlVideoBar = new AudioControlBar(myVideoTexture)

Placement

// Once you have created an AudioControlBar you can adjust
// it's placement on the left hand side of the screen
audioControlVideoBar.setOffset(34)

Other Features/Settings

// Mute and Unmute the audio
audioControlVideoBar.mute()
audioControlVideoBar.unmute()

// Set the volume (0-100)
audioControlVideoBar.setVolume(50)

// Set the Maximum Volume (Careful with this. Some videos/streams are LOUD.
// So this is an audio dampener of sorts. Default: .2
audioControlVideoBar.setMaxVolume(1)
