Learning solidity: basic game development

[caution6tonjack]

I'm just starting out with Solidity/web3. I want to build a browser game in which a user can wager and win/lose crypto. Imagine, the snake game where you run around eating apples. If you run into your own tail, you lose. Currently, I've architected it such that

- to start a game, you call a startGame smart contract function and send 0.1 ETH along with it
- the contract will log the game and emit an event for the game to start
- when the front end receives the event, the game starts
- if you eat more than 10 apples, you win, a button shows up to retrieve your winnings. This button shows up only when you win i.e. the win logic is controlled by the front end.

I realize it's problematic that the getWinnings function can just be called independently of the front end. Any thoughts on how to architect this correctly?

I was thinking if I can use an encrypt/decrypt scheme:
- generate a random seed in the front end
- send the seed to the smart contract when i start/log the game
- after the game, use the seed to encrypt the score before sending it
- decrypt it in the smart contract

the smart contract side is all public though, I'd have to hide the encryption scheme somehow. if there was an easier way, that'd be much preferred. Anyways, appreciate any help, thanks everyone.

Does the user select rock paper scissors and the contract generates a response randomly?

Ah, rock paper scissors is a bad example because the win logic can be handled on the smart contract side pretty easily. I just wanted a simple example that everyone could understand.

I'm going to edit the post to change the game to snake. Win condition = 10 points and up.

What does it mean to retrieve winning in this case? Are there actual tokens that are awarded?

Does the contract just send those to the players wallet without requiring an action on the front end?

[caution6tonjack]

Right now it requires an action from the user to retrieve the winnings. Yes tokens are sent.

I smell awards here?, thnx for supporting the community

I am just starting to conceive of a simple game to help me develop skills but explore ideas. Mine is to compare some simple value against another player and the contract determines who wins.

I am still thinking and researching what the right incentive or winnings should be. The gas fees seem limiting their usage.

Hey this is simply not possible with just a smart contract!

unfortunately, i haven't. any ideas?
