About
The problem it solves Flow Racer is built in Unity using Flow-Unity-SDK. # Problem Flow Racer is solving 2 critical problems for gamers: ### Low availability & low trustability of paid competitive matches Gamers love competiting against each other and especially when there's a prize pool, but for that they have to wait for official tournaments or local skrims organised by a small team of gamers. Moreover, even after ending with a winning position, the prize payout is delayed. ### Game asset security concerns With game progress data stored on centralized servers, security of hard earned game assests is number one concern. Flow Racer game assests are present on-chain as NFTs so that a user never loses their car asset and also gets an option of trading their car in the free market. # Solution With Flow Racer, a competitive gamer gets access to - on-demand paid competitive matches - transparent & decentralized entry fee collection - instant & trustworthy prize pool distribution and payout - game asset security: car nft buying & sellingFl
How it's made
Challenges we ran into - Poor error logging on Flow Testnet: Difficulties while debugging the cdc contracts and transactions. Like in one case, if the user Testnet FLOW vault had a particular token it cannot hold any other token with the same name. So while debuging we had to create new accounts each time we wanted to make a change to the token contract since changing the names would've lead to other errors in previously written contracts. - Integrating Wallect Connect as wallet provider: WalletConnectProvider was not a Scriptable object which caused initial problems with registering a wallet provider.
