Welcome to We Are On The Planet. In this project, everyone has one unique planet. You can chat with others, visit friends, finish tasks, build your own NFTs, and even transact your NFTs to gain some profits!
As blockchain technology continues to progress, the widespread adoption of blockchain services appears increasingly likely in the future. However, for users unfamiliar with blockchain technology, navigating complex services can be challenging. Therefore, our goal is to establish a metaverse that simplifies and enhances the user experience, providing an accessible and entertaining platform for exploring diverse blockchain services.
- Metamask Wallet(Chrome browser) installed
- One computer should start as host for multiplayer gaming(At the current demo stage, facilitating transfers involves manual intervention by the host, who interacts with the Metamask interface on behalf of clients. While we acknowledge the potential for future automation of this process, it remains a manual task for hosts during this stage. The host only needs to click OK when ever any metamask interfave pops up.)

We opted for Unity as our frontend development platform due to its extensive capabilities. Unity empowers us to use code for manipulating the behavior of 3D objects, constructing interactive UI elements, and designing intricate shading for the metaverse. Its versatile feature set provides a robust foundation for creating a dynamic and engaging user experience. Furthermore, Unity offers a wealth of comprehensive documentation, enabling us to swiftly grasp its functionalities within the constraints of a hackathon's limited timeframe. This accessibility and support make Unity an ideal choice for efficient development and quick learning during the hackathon.
The planet functions as a gravitational center, drawing all objects with mass towards its surface and maintaining them grounded. Additionally, it aligns the normal vector of these objects with the normal of the planet, ensuring a harmonized orientation.
To facilitate precise block placement within a 10x10x10 grid, we implemented Unity's raycasting system to determine the mouse click location. This system ensures that the placing position snaps to the grid, enabling players to create structured arrangements. By storing the position and color data of the placed blocks, we can easily recreate the appearance of the NFTs constructed by players. This data allows us to showcase their creations within the game environment and provides the flexibility for subsequent editing.
Building upon the stored NFT data, we can dynamically recreate the NFTs and render them into images for display within the menu. This functionality allows players to visually preview and appreciate their NFT creations directly in the game interface.
We use Unity Relay Service to handle multiplayer gaming. As long as one computer starts as the host, everyone can join the metaverse anytime, anywhere.
In the Login page, player join the game by entering the join code provided by the host.
As for chatting with people in the metaverse, we use Unity Vivox Service to make users communicating with others without obstacles.
For each friend of a player, we assign an unique channel for the player and the friend, so only the player and the specific friend can see the message in their chat room.
For all the people in the same planet, we create an audio channel for people to talk in.
We utilize the 3D modeling software Blender to craft the visual aesthetics of the planet, plants, and various assets within the metaverse.
By leveraging the shadergraph system of Unity, we have implemented a toon shader to bestow our metaverse with a distinctive and stylized appearance.
Enhancing the planet's surface with lifelike grass, we leveraged Unity's use of triangles for mesh construction. Through calculations based on the barycentric coordinates of each triangle, we positioned the grasses. Their rotation was adjusted to align with the planet surface's normal, while introducing a single degree of freedom for rotation to introduce a randomness to the grass arrangement.
For the grass color, we employed ShaderGraph to blend the grass color with the ground color, ensuring a cohesive and natural appearance. This approach contributes to a more harmonized and visually pleasing integration of the grass with the surrounding environment.
We use MongoDB to store the data of players. For connecting MongoDB in Unity, we use the Realm .NET SDK to store, write and update player's data in time.
We have two types of token : WATP-T and WATP-N.
This is the fungible token which players use to pay everything (e.g buy others' NFT) in the metaverse. We use ERC865, which is the extension of ERC20(ARC20) to implement this token. With ERC865, players in the mataverse do not need to have TAREA to pay the gas fee. They can pay the gas fee by this WATP-T token.
The following picture shows how the ERC865 implement gasless transaction:
The service provider will approve the transaction by verifying if the sender has the same address as the address that is used to sign the message. After that, the transaction will be executed and a fee will be sent to the service provider.
This is the non-fungible token(NFT) in the metaverse. We implement this by ERC721(ARC721) with several custom function similar to ERC865 to handle gasless transaction. For each WATP-N token minted or transferred, 5 WATP-T tokens will be paid as the gas fee. The WATP-N tokens will be shown as several colorful blocks in the metaverse, and players can launch or attend an auction for it.
To connect Unity with Metamask and blockchain, we use the Chainsafe Unity SDK. This SDK provides players and hosts a concise interface to sign various messages, such as transfering and minting NFTs, which links the in-game trading system.
Given the time constraints during the hackathon, certain ideas were left unexplored. We envision incorporating these unfinished concepts into future versions of our metaverse, allowing for continuous improvement and expansion of features in subsequent releases.
Despite time constraints, we aim to enhance the visual appeal of our UI, striving for a more polished and stylistically fitting appearance. While acknowledging the current limitations, our commitment is to iteratively refine the UI to achieve a more desirable and cohesive aesthetic.
We aspire to incorporate mini-games into our metaverse, providing users with opportunities to earn special achievements and, most importantly, to enhance their overall enjoyment.
We planned to introduce the capability for hosting events, such as concerts, within our metaverse. This addition aims to foster increased interaction among users, creating a vibrant and socially engaging environment for everyone involved.
In our upcoming development phases, we plan to integrate our metaverse with LLM APIs to introduce chatbots. These chatbots will serve as guides, offering users valuable insights and knowledge about blockchain technology. Additionally, users will have the opportunity to engage in conversations with NPCs, enriching their overall experience within the metaverse.
