Production patterns for Godot 4.x game development with GDScript, covering architecture, signals, scenes, and optimization.
resources/implementation-playbook.md.resources/implementation-playbook.md for detailed patterns and examples.Playbook samples are separate-file fragments; supply Input Map actions, scene nodes, Player/State subclasses, die() and other project-specific helpers before use. The pool requires a CanvasItem-compatible scene root and explicit physics/collision reset: disabling processing/visibility does not prevent every signal callback, so inactive objects must reject hits. Validate initial states and guard asynchronous scene loads/transitions against duplicate requests. Save files require schema/version/range validation and atomic replacement; a hardcoded encryption key in a distributed game is extractable and cannot protect secrets or establish anti-cheat trust. Check save/open/delete failures. Pin the Godot version and use the profiler before claiming gains. See Godot pause/process modes.
