Winner's Dev Notes

Register Cocos2d-x 3.17 Lua keyboard press and release callbacks with cc.EventListenerKeyboard, handle KeyCode values, attach the listener, and clean it up.

Use Lua coroutines, yield, and resume to build a cooperative task scheduler and coordinate non-blocking network I/O without confusing concurrency with parallel execution.

Use Lua's debug library to inspect functions, stack frames, local variables, upvalues, coroutines, and execution hooks while understanding performance and sandbox risks.

Learn Lua coroutine creation, resume and yield value flow, status transitions, iterator patterns, main-loop ownership, and event-driven program structure.

Understand Lua garbage collection through reachability, weak-key and weak-value tables, caches, finalizers, external resources, and practical collectgarbage controls.

Understand Lua _G and _ENV, dynamically named globals, undeclared-variable checks, isolated module environments, and explicit environments passed to load.

Shuffle a Lua array uniformly with the Fisher-Yates algorithm, understand its linear complexity, and choose between an in-place function and a copied result.

Implement object-oriented Lua with tables, functions, metatables, self methods, constructors, inheritance, private state, callable objects, and alternative object models.

Customize Lua arithmetic, comparison, indexing, assignment, calls, and string conversion with metatables, __index, __newindex, and proxy-table patterns.

Understand why require is Lua's standard cached module loader while import is usually a framework helper with project-specific path, return-value, or reload behavior.
