Roadmap

  1. Account can create a planet and upgrade mines. Only mines are available. :heavy_check_mark:
  2. Integration of ERC721: planets will be NFTs. :heavy_check_mark:
  3. Integration of ERC20: resources will be tokenized. :heavy_check_mark:
  4. Add energy production requirements for mines. :heavy_check_mark:
  5. Add time constraints for buildings upgrades. :heavy_check_mark:
  6. Implementation of Robot Factory. :heavy_check_mark:
  7. Add research lab.
  8. Add technologies.
  9. Allow creation of colonies.
  10. Implement logic for space travel between planets.
  11. Implementation of basic ships:

This will most likely keep me busy for a while. The rest of the roadmap is yet to be decided.

Game Deployment Workflow

  1. Deploy minter contract:
nile deploy erc721_minter --network goerli [owner.contract_address]
  1. Deploy ERC721:
nile deploy --network goerli ERC721 0x4e6f47616d6520 0x4f474d302e31 [minter.contract_address] 54 105 112 102 115 58 47 47 81 109 78 82 54 106 86 109 68 86 55 115 71 81 102 67 114 55 120 116 114 80 67 117 78 115 97 100 85 89 104 83 122 75 118 106 112 65 100 49 68 121 83 112 84 84 47

  1. On minter contract invoke setNftAddress with ERC721 as parameter.

  2. Deploy main game contract:

nile deploy Ogame --network goerli [erc721.contract_address] [owner]

  1. On minter invoke setNftApproval with Ogame.contract_address as operator.

  2. Invoke mint_all function on erc721_minter contract with parameters n = 150 and token_id.low starting from 1. Minting more >= 200 planets in a single transaction triggers MAX NUMBER OF STEPS error from Starknet.

  3. Deploy metal token:

nile deploy ERC20_Mintable --network goerli 0x6f67616d65206d6574616c2076302e31 0x4f674d455476302e31 18 0 0 [game.contract_address] [game.contract_addres]
  1. Deploy crystal token:
nile deploy ERC20_Mintable --network goerli 0x6f67616d65206372797374616c2076302e31 0x4f6743525976302e31 18 0 0 [game.contract_address] [game.contract_addres]
  1. Deploy deuterium token
nile deploy ERC20_Mintable --network goerli 0x6f67616d652064657574657269756d2076302e31 0x4f6744455576302e31 18 0 0 [game.contract_address] [game.contract_addres]
  1. Invoke erc20_addresses on Ogame contract with resources token addresses as params.
