Smart Contract for Minigame: Single-Button Platformer

[jimenezz22]

Description

This task involves implementing a smart contract function, submitScore, using Dojo Engine and Cairo, to record scores achieved in a minigame. The function will also handle logic for granting rewards or additional points based on the player's performance.

A good reference for this implementation is the frontend issue Minigame: Single-Button Platformer (GitHub link), which outlines how the minigame operates and tracks player performance. Aligning the smart contract logic with this frontend issue will ensure consistency across the system.

---

Tasks

Define the submitScore Function 🏗️

• Create a Cairo function submitScore that takes the following parameters:
  • player_id: The ID of the player submitting the score.
  • tamagotchi_id: The ID of the Tamagotchi linked to the game.
  • score: The score achieved in the minigame.
• Validate the inputs to ensure:
  • The player_id and tamagotchi_id exist and are correctly linked.
  • The score is non-negative and within a reasonable range.
• Store the score in the appropriate on-chain data structure, such as a mapping or table.

Implement Reward Logic 🎁

• Add logic to grant rewards based on the submitted score:
  • Define thresholds for rewards (e.g., score >= 100 grants bonus points or items).
  • Update the Tamagotchi's attributes (e.g., happiness, health, or experience).
• Ensure rewards align with the frontend game logic, avoiding discrepancies between the user experience and on-chain outcomes.

Integrate with Dojo Engine ⚙️

• Leverage Dojo Engine components to manage entity systems for players and Tamagotchis.
• Ensure compatibility with existing entities and systems in the BabyBeasts ecosystem.

Testing and Validation ✅

• Write unit tests in Cairo to validate:
  • Proper score recording.
  • Correct reward assignment based on various score thresholds.
• Test integration with the frontend to confirm consistency with the game flow.

---

Deliverables 📂

• Fully implemented submitScore function in Cairo.
• Reward logic that updates Tamagotchis' attributes based on scores.
• Test suite ensuring the reliability of score recording and reward assignment.
• Documentation detailing the function parameters, logic, and examples of usage.

---

Acceptance Criteria 🎯

• The submitScore function records scores accurately on-chain.
• Rewards are assigned correctly and reflect in the player's Tamagotchi attributes.
• The smart contract logic aligns seamlessly with the frontend issue Minigame: Single-Button Platformer.
• All tests pass, and the integration is smooth and bug-free.

---

Additional Notes 📝

• Follow best practices in Cairo for security and gas optimization.
• Coordinate with the frontend team to ensure proper alignment of game logic and on-chain interactions.

Hey, I'm new to this platform and want to contribute to this issue.
To be able to solve this issue, I will implement the submitScore function in Cairo by validating player and Tamagotchi IDs, recording scores on-chain, and giving rewards in terms of predefined thresholds. Rewards will include updates to the Tamagotchi's attributes such as happiness or experience. Sufficient unit testing will ensure accuracy and alignment with the frontend logic for seamless integration.

Problem

Smart Contract for Minigame: Single-Button Platformer

Solution

1. Create a map node to save the information of the different users and Tamagotchi
2. Create the function to ensure that player_id and tamagotchi_id exist in the blockchain in the correct Cairo contract
3. Create the function submitScore that saves the score of the player with that Tamagotchi
4. Define thresholds for rewards
5. Update the Tamagotchi status in the corresponding Cairo Smart Contract
6. Integrate with Dojo Engine
7. Create unit test for the contract
8. Create the documentation of the functions created
