Sammich System (for Decentraland)

How to add game plane screen to your SDK game or scene in Decentraland

Requirement: Your scene should be SDK7, this component doesn't work with SDK6.

In the root folder of your SDK scene, execute npm install dcl-sammich-screen@latest

Then you can create an instance of the game with something like this:

import {createSammichScreen} from "dcl-sammich-screen";
import {getRealm, getSceneInformation} from "~system/Runtime";

export async function main() {
  const sammichScreenInstanceRoomId = JSON.parse((await getSceneInformation({})).metadataJson).scene.base;

  const rootEntity = engine.addEntity();
  const sammichScreen = await createSammichScreen(rootEntity, {
    position:Vector3.create(8,2,8),
    rotation:Quaternion.Zero(),
    scale: Vector3.create(3, 2, 1),
    defaultTextureSrc:"https://sammich.pro/images/spritesheet.png",
    baseInstructionVideoURL:"https://sammich.pro/instruction-videos",
    colyseusServerURL:"wss://sammich.pro/colyseus"
  },  sammichScreenInstanceRoomId);
  
  sammichScreen.onEvent(({type, data}) => {
      console.log("something happened");
      console.log("event type", type);
      console.log("event data", data);
      console.log("sammichScreen state", sammichScreen.getState())
  });
}
