TurboPlay Blockchain service that provides connectivity to the Ethereum Network and APIs for the TurboPlay frontend application.
We are one of the first videogame companies to demonstrate tokenization games and game assets via smart contracts.
All source code is released as is under the Apache v2 licensing.
Prerequisites: In order to set up and run the server you will need Nodejs, NPM, and MongoDB
This server relies on native modules, if you are running it on a windows system, you may need to globally install the windows-build-tools package via NPM.
Once you meet the prerequisites, clone to local project directory and install dependancies with:
npm install
This package also requires gulp, truffle, and ganache-cli(required for local blockchain only) packages to be installed globally. To install them run
npm install -g ganache-cli truffle gulp-cli
Be sure to have mongoDB running in a seperate terminal. Then to run the server on Ropsten with hot reloading:
gulp start
By default, this will use the last-deployed contract, if you need to test on Ropsten with a fresh contract, follow the deployment instructions below.
To run the server on a local blockChain, follow the deployment instructions below, and then run:
gulp start:local
- Set a mnemonic in process.env.mnemonic if you would like to use your own accounts to manage the contract. There is a test mnemonic currently set in config.js. The test Mnemonic is "donate leisure glass eye pitch seek tray update nerve fortune paper effort"
If you change this in your environment variables, be sure to change it in the commands below, and in MetaMask to ensure that you control the correct accounts in your deployment.
-
Ensure that the first account generated by your mnemonic has some ether.
-
(optional) if you are deploying to a local blockchain, open ganache in a seperate terminal with the command:
ganache-cli -i 101 -m "donate leisure glass eye pitch seek tray update nerve fortune paper effort"
This is used to control the network ID of the blockchain you create, as well as the mnemonic used to generate unlocked addresses with Ether.
For a more realistic simulation of the Ethereum block chain, consider running ganache-cli with -b 90 to put up to a 90 second delay on transactions.
-
Run the following steps
cd truffle truffle build
for Ropsten:
truffle migrate --network ropsten
or for a local blockchain:
truffle migrate -i 101
You may need to add the --reset flag if you are deploying a contract without any changes.
Ensure that there is a variable for each contract in the config.js file (follow the pattern of the paymentContractAddress export). Use this variable to instantiate contracts.
You can access the contract Owner address & key through the HD Wallet provider - defined in truffle.js, or by inputting the mnemonic directly into MetaMask.
If you will be running tests locally, we recommend using MetaMask to transfer ether from the accounts generated by the mnemonic to accounts generated for your users.
gulp lint
To fix some errors automatically:
gulp lint:fix
The api is currently staged on the Ropsten Network at https://turboplay-staging.herokuapp.com/
The API is implemented using the JSON-RPC 2.0 specfication, to test the API, you can install a tool like Postman to create POST requests.
The header of the request must have Content-Type: application/json and all requests must use the POST method. Example body and response JSON are supplied below for each method.
- signUpUser
- login
- setAccount
- getAccount
- getAccountBalance
- getErrorLog
- getGames
- buyGame
- registerGame
- getOwnedGames
- verifyGameOwner
NOTE: In the JSONRPC 2.0 standard, method parameters can be supplied as an object, as seen below, or as an array. The order of the array is fixed, and methods must be supplied in the order listed in the chart for each method below.
All unsuccessful responses will follow the template below, providing additional information about the error.
