OpenSim Marketplace

Introduction

OpenSim Marketplace is a marketplace for the OpenSim environment. Users can upload their creations and also download new ones to use. There are also multiple ways to locate assets, searching by type or a search string.

Installation

Prerequisites

• Must have a preexisting OpenSim database (installation process found here.

• Must have Node >= 8.10 and npm >= 5.6. If not, you can grab them from this link here.

  • Check versions with node --version and npm --version.

• Optionally, you can also use yarn instead of npm.

  • Check version with yarn --version.

• Must have a valid version of Git.

  • Check version with git --version

Installing

1. Install git repository

In the command prompt or terminal, move the folder that you would like to keep the local repository. Once there type in the console:

git clone https://gitlab.com/senior-design-project-12/opensim-marketplace.git

This will create a local repository identical to the Gitlab repository.

type cd opensim-marketplace to enter the project folder. Within, there should be 2 folders: opensim-marketplace and backend

2. Install packages for frontend

In the command prompt or terminal, in the root of the local repository, type the following:

cd opensim-marketplace

In the folder, install the packages:

npm install or yarn

This will create a node_modules folder holding all third party libraries

3. Install packages for backend

In the command prompt or terminal, in the root of the local repository, type the following:

cd backend

In the folder, install the packages:

npm install or yarn

4. Modify OpenSim assets table

Run the SQL script modifyDB.sql on the database your OpenSim instance uses:

• Change the first (uncommented) line's value from USE DATABASE_NAME_EDIT_ME; to your database/schema name (e.g. USE opensim;)
• Open the script in MySQL Workbench and run it
  • Adds 2 new columns to the assets table: public (TINYINT(1) = 0) and marketplace_icon (LONGBLOB = NULL)
  • Adds the 3 stored procedures called by the marketplace website

5. Add/Modify OpenSim user Wifi Admin with password kenny123
   1. temporary until save iar via user/session IDs is implemented

Running

CONFIG.INI

Must ensure that there is a valid connection to the database. In order to connect to the database, modify the config.ini file in the src/config folder.

• PORT for changing port server runs on. Default is 5000

• DB_URL for the IP of the database or location name of the database.

• DB_USERNAME Username of connection

• DB_PASSWORD Password of connection

• DB_NAME Name of the database to connect to (Ex: 'opensim').

• REGION_USER Username to open a Region Console

• REGION_PASS Password to open a Region Console

• INI_LOCATION Absolute Location of Regions.ini file

• OPENSIM_ADDRESS ip address of Opensim Server

• OPENSIM_PORT for the default robust port. Default is 8002

• MARKETPLACE_ADD-LOCATION Absolute location of where marketplace temporary files will be created

• TEST_UUID User ID for testing. Used for testing only

Frontend

In the command prompt or terminal, move to the opensim-marketplace directory.

Note: Before running the development react server, a location for the backend server must be specified. In the frontend directory, open the package.json file and change proxy from http://localhost:5000/ to the where the server will be run.

To run the development react server, type:

npm start

Note: This will start the React at http://localhost. or at whatever port is specified in package.json. To change this port, find the scripts section of package.json and modify the start script to specified port.

Note: While editing the project in the code, any edits that are made to the src or public folder will be automatically updated on the browser window.

At any time, you can run npm run build or yarn build. This will create an optimized build in the folder within the frontend directory called build. The build folder is a static HTML file with vanilla javascript. This HTML is referenced by the backend Node.js server

Note: You can run this html file directory and see the website load, but it will not be functional even with the backend server running. To work correctly, it must be run through the backend server

Backend

In the command prompt or terminal, move to the backend directory and run the following command:

npm run dev

This will start a local Node.js server at localhost:5000 or whatever port specified.

When accessing http://localhost:{port}/ or wherever the backend server is started, the production build found in opensim-marketplace/build of the marketplace should load. This will work exactly as the React Development Server should if run.

Note:

• The backend requires that there be connection to the database to function properly
• The React development server will rely on the backend being up and running. Always make sure that both are running together to ensure that everything works as intended.
• Any time you pull or merge from the repository, make sure you run npm install or yarn to download any new modules

Marketplace User Manuel:

Page Layouts

Login Page

The login page consists of a form submission to login with OpenSim credentials; These being first and last name, and password. The login page is accessible on launch, as well as after the user has logged out of the application via the logout button.

Home Page

After proceeding through the login process, the user will be greeted by the home page of the website. This contains a navigation bar which will be talked about in the following section. The homepage has a welcome message greeting the user, as well as multiple search categories that enable the user to search by asset type (texture, model etc). There is also a carousel of recently uploaded items on the homepage, showcasing some new items that the user may be interested in.

Navigation Bar

The navigation bar is the main way the user interacts with the website, given that it is available from every page except the login screen. The navigation bar has a redirect that sends the user to the homepage, as well as to the inventory page. The user can log out of the application which will redirect them to the login page. Lastly, the user can search for items with text via a search box, preferably by the items name.

Search functionality

There are currently two types of search functionality available to the user. The first one through the navigation bar, which allows the user to search by the name of the item. Leaving the search box blank will show all available items in the database. The second are the categories located on the homepage, which when selected will redirect to the search page and search for only the asset type that was selected. On this page selecting an item card will redirect to the items page.

Item page

The item page contains the most descriptive information about each asset, showing the name, asset type, creator, and date and time of upload. The item page is the only page where an asset can be added to a users inventory. If the user is the creator or already has the asset in their inventory, the “Add To Inventory” button will redirect to their inventory. Otherwise, the user can simply add the asset to their inventory via the “Add To Inventory” button.

Inventory Page

The inventory page is the only page where the user can manage the assets in their inventory. They have the option to remove assets from their inventory, as well as view the item page. The user also has many capabilities if they are the creator of the asset. If the user is the creator of the asset, they can opt to make it public or private, which is like uploading and downloading. Public makes the asset available to all users of the marketplace, and private makes an asset available to only the creating user. All of this can be done from the buttons on each assets item card in the inventory screen.

3. Finding Assets:

There are several ways/places to find assets on the marketplace:

On the Home Page:
    In the bottom section of the Home Page labeled “Recently Updated Items”  
Search categories on the Home Page
    Selecting a category directs to the search page and displays its assets
Search Page:
    Search for assets by name using navigation bar which redirects to search page with assets matching the search

4. Adding Item Inventory:

   Once you have found the asset you are looking for and have been redirected to its corresponding Item Page, you can now add the asset to your inventory via the “Add To Inventory” button. Once clicked the asset will be added to your OpenSim Inventory where it can be viewed via the marketplace Inventory Page as well as the in-client inventory screen located in the OpenSim Client. You will also be redirected to your Inventory where your added asset will be displayed.

Note: Both the OpenSim Client and the OpenSim Marketplace share an Inventory. This is how items are “Downloaded” and “Uploaded”.

5. Uploading an Inventory Item:

   In order to upload an item, you must be the creator of said item, meaning you must have been the creator of the item in OpenSim. If you are the creator, you can go to your inventory page through the navbar, and locate the item that you wish to upload to the marketplace. Once you have found the item, simply check the public button if it is currently private, and it will be “uploaded”. If you would like to hide or “unupload” your item, hit the private button within the inventory page on the item you want to hide, and it will no longer be public on the marketplace.

6. Logout:

   Once you have finished using the marketplace you may logout of your OpenSim Account via the “Logout” text located in the top-right corner of the screen in the dark colored Navigation Bar. Once clicked you will be redirected to the Login Page where you can login once again.

Note: If instead of “Logout” text , a square containing three horizontal lines is located in the top-right corner of the screen. Either expand the size of the browser window or simply click the three line box to reveal the “Logout” text.
