Getting Started

This is a simple Tetris Demo that applied with a leaderboard stored on block chain, showcasing the ability to develope fully on-chain game with Godot Engine, with our custom module https://github.com/qingfengzxr/gdscript-web3 for GDScript.

In this demo, all the score you submit will stored in a OP contract, and holding a global leaderboard of the Tetris game.

Basic Control:

• A and D for moving brick left or right

• S for accelerate dropping

• Space for instant dropping

• Q and E for rotating brick

Your personal best score and current score will shown at top left. And next brick will shown at top right.

To restart or return to menu, please press Esc button.

Login & Logout

You can create a account for the leaderboard by login with Username and your OP PrivateKey.

The PrivateKey will only stored at local for communicating with the contract. You can delete the stored PrivateKey anytime by logout. The data is stored at Godot's default userdata path (user://).

Windows: %APPDATA%\Godot\app_userdata\[project_name]
macOS: ~/Library/Application Support/Godot/app_userdata/[project_name]
Linux: ~/.local/share/godot/app_userdata/[project_name]

To get more detail of local userdata storage please refer to https://docs.godotengine.org/en/stable/tutorials/io/data_paths.html

The leaderboard will show top 100 score on the chain, and your personal best score. Your username will be lighted in red.

Eth Tool

We use functions in ./Scripts/eth_tool.gd to communicate with block chain.
