Implement the logic player movement

[AzaleeX]

Summary

Implement the core logic for handling player movement on the Minecraft Bedrock server. This system will manage the reception, validation, and synchronization of player movement data between clients and the server, ensuring smooth gameplay and consistency across all connected players.

Details

Proposed System Flow

1. Receiving Movement Packets:

   • Handle incoming packets from clients containing movement data such as:
     • Position: X, Y, Z coordinates.
     • Rotation: Yaw and Pitch values.
     • Additional Data: Information like speed, jump status, or crouch state.
   • Validate these packets to ensure they adhere to expected parameters, preventing issues such as:
     • Players moving faster than allowed (speed hacks).
     • Invalid or nonsensical coordinates.

2. Server State Update:

   • Process validated movement data and update the player's state in the server's memory.
   • Ensure that the new position is consistent with environmental rules, such as gravity and block collision detection.

3. Collision and Environment Handling:

   • Detect collisions with the environment (blocks, entities).
   • Prevent invalid actions such as:
     • Walking through walls.
     • Standing inside other entities or blocks.

4. Broadcast Updates:

   • Notify other players about the updated position and state of the moving player.
   • Ensure that these updates are timely to maintain smooth player movement visuals across all clients.

5. Optimization and Lag Compensation:

   • Reduce the impact of latency on movement by implementing predictive models or lag compensation techniques.
   • Ensure the server remains performant even with multiple players.

Benefits

• Consistency: Guarantees that all players see the same movements for every other player.
• Fairness: Prevents exploitation through movement hacks or glitches.
• Fluid Gameplay: Ensures player movements are smooth and responsive across varying network conditions.

Additional Considerations

• Integrate with anti-cheat systems to monitor and report suspicious movement patterns.
• Test the system extensively under different conditions, including high-latency connections and high player counts.

Tasks

• Implement packet reception for player movement data.
• Validate movement data to ensure it complies with game rules.
• Update server state with validated player positions.
• Implement collision detection for blocks and entities.
• Broadcast position updates to other players.
• Optimize movement handling for performance and lag compensation.
• Test the system with multiple players in various scenarios.

Impact

By implementing this system, the server will handle player movements efficiently and securely, providing a smooth and fair experience for all connected players.
