World Arcade

Cartesi Rollups Node version: 1.2.x (sunodo version 0.10.x)

The World Arcade allows users to play riscv-binaries of games on a RISC-v Cartesi Machine on the browser, submit the game moves onchain so the session will be replayed a Cartesi Rollups DApp to generate a provable score. Naturally you can upload you own games.

DISCLAIMERS

For now, this is not a final product and should not be used as one.

Requirements

• npm to install dependencies and run the frontend
• Sunodo to build and run the DApp backend
• Metamask to sign transactions in the frontend
• json-schema-to-typescript to generate typescript interfacesnpm install -g json-schema-to-typescript --save
• cartesi-client, an interface to cartesi rollups framework

To build the DApp, two images are also required: riv/toolchain and sunodo/sdk:0.2.0-riv.

• To generate riv/toolchain, clone RIV repository and in its directory do:

make toolchain

• To generate sunodo/sdk:0.2.0-riv, in the world-arcade project directory do:

docker build --tag sunodo/sdk:0.2.0-riv . --target sunodo-riv --progress plain .

Building

Build backend with:

sunodo build

You should also install the frontend dependencies. First install cartesi client, then run:

cd frontend
yarn
npm link cartesi-client

Running

Run the DApp environment with:

sunodo run

Then deploy the Rives Screenshot NFT contract (you should have already installed frontend dependencies)

cd frontend
MNEMONIC='test test test test test test test test test test test junk'
RPC_URL=http://127.0.0.1:8545
DAPP_ADDRESS=0x70ac08179605AF2D9e75782b8DEcDD3c22aA4D0C
BITMASK_ADDRESS=0xF5B2d8c81cDE4D6238bBf20D3D77DB37df13f735
forge create --constructor-args $DAPP_ADDRESS --rpc-url "$RPC_URL" --mnemonic "$MNEMONIC" --json contracts/RivesScoreNFT.sol:RivesScoreNFT --libraries node_modules/@cartesi/util/contracts/Bitmask.sol:Bitmask:$BITMASK_ADDRESS

Finally, run the frontend

cd frontend
yarn dev

You will be able to mint the NFTs once the epoch has finished, but you can increase the time of the local dev chain with

curl -H "Content-Type: application/json"  -X POST --data '{"id":1337,"jsonrpc":"2.0","method":"evm_increaseTime","params":[864000]}' http://localhost:8545
