This is a demo of rock paper scissors game in solidty.
A basic commit-reveal pattern is used in this DApp. Please read smart contract best practice: remember that on chain data is public for more detail.
- Compile rps.sol and deploy (e.g. using remix)
- Edit app.js, replace address variable with your deployed contract address
- Start a httpserver (e.g. httpster), browse and open index.html. You need to install metamask to use this app
- Start two web pages, each one serve as a player. If play in single machine, do as following:
- Open tab 1, switch account to address 1 in metamask, commit
- Open tab 2, switch account to address 2 in metamask, commit
- Go back to tab 1, switch account to address 1 in metamask, reveal
- Go back to tab 2, switch account to address 2 in metamask, reveal
- Go to any tab, choose winner, wait for result
- If anything goes wrong, error will be in alert box. For out of gas problem, increase gas limit in metamask
This is for a live coding demo, and the contract/UI is not full-featured. Feel free to copy/modify it to make a more complete one.
Have fun :-)
