Genre: MOBA (Multiplayer Online Battle Arena)

Expert blueprint for MOBAs emphasizing competitive balance and strategic depth.

NEVER Do (Expert Anti-Patterns)

NEVER trust the client for damage calculation or resource costs; strictly validate mana, ranges, and hit detection on the authoritative server using multiplayer.is_server().
NEVER use TRANSFER_MODE_RELIABLE for continuous movement; strictly use UNRELIABLE or UNRELIABLE_ORDERED for position/velocity to prevent network congestion.
NEVER sync units at 60Hz; strictly use a lower tick rate (10-20Hz) via MultiplayerSynchronizer and implement Interp/Client-Side Prediction for visual smoothness.
NEVER attach individual synchronizers to hundreds of minions; strictly batch state updates into compressed byte arrays via a central manager.
NEVER synchronize complex Engine objects directly; strictly serialize state into primitive properties or Dictionaries for reliable peer-to-peer sync.

NEVER use expensive pathfinding for all minions every frame; strictly use Time Slicing to spread get_next_path_position() calls across multiple frames.
NEVER query NavigationAgent paths inside _process(); strictly use _physics_process() to interact with the navigation server and avoidance systems.
NEVER use complex visual geometry for NavMesh baking; parse simple primitives to avoid stalling the RenderingServer or crashing the engine.
NEVER set path_search_max_polygons too low in large maps; agents will stop or walk incorrectly if the limit is reached before the destination.
NEVER use Area2D for high-performance Fog of War LOS; strictly use nodeless physics queries (intersect_ray) to bypass node overhead.
