This is a blockchain game made in Rust on MultiversX. The project contains 2 smart contracts, frontend and several microservices.
Inspired by r/place, we created a game in which one player can paint one pixel on the moon at a specific time. The resource used to paint a point into a specific color can be harvested and claimed once a time delay has passed if the user registered for harvesting.
The map is a sphere with generated fixed points. Using perspective projection, we can represent 3D spaces into 2D coordinates. These 2D coordinates are stored into the paint-the-moon smart contract, along with the state (color) of each point at a given time.
The frontend receives the 2D coordinates and translates them into 3D coordinates and renders the map. All the sc requests' results are received from the microservice.
The microservice queries the smart contract once in a while, caches the information and prepares the information format for the frontend.
