To ensure that enable_debug_logging persists across reloads, you must update the serialization logic in globals.gd. Currently, your centralized save flow is triggered by the signal in GameSettingsResource, but the _save_settings() and _load_settings() functions in globals.gd only handle log_level and difficulty. While your refactored GameSettingsResource correctly emits the setting_changed signal, the Observer (Globals.gd) was only "notified" that something happened; it didn't know it needed to write that specific new field to the disk. By updating these two functions, you complete the persistence loop for the debug flag. --- scripts/gameplay_settings.gd | 2 +- scripts/globals.gd | 13 +++++++++++ test/gut/test_settings_observer.gd | 36 ++++++++++++++++++++++++++++++ 3 files changed, 50 insertions(+), 1 deletion(-) diff --git a/scripts/gameplay_settings.gd b/scripts/gameplay_settings.gd index 94766b7e1..fee481b6a 100644 --- a/scripts/gameplay_settings.gd +++ b/scripts/gameplay_settings.gd @@ -98,7 +98,7 @@ func _on_tree_exited() -> void: ## Disconnects signals, restores previous menu if not intentional, clears JS/DOM state. ## :rtype: void Globals.log_message("Gameplay Settings _on_tree_exited called.", Globals.LogLevel.DEBUG) - + # Disconnect the global resource observer to prevent stale references if Globals.settings.setting_changed.is_connected(_on_external_setting_changed): Globals.settings.setting_changed.disconnect(_on_external_setting_changed) diff --git a/scripts/globals.gd b/scripts/globals.gd index d1c92abd0..d93e06960 100644 --- a/scripts/globals.gd +++ b/scripts/globals.gd @@ -170,6 +170,17 @@ func _load_settings(path: String = Settings.CONFIG_PATH) -> void: "Invalid type for difficulty: " + str(typeof(loaded_difficulty)), LogLevel.WARNING ) + + # NEW: Load the debug logging flag + if config.has_section_key("Settings", "enable_debug_logging"): + var loaded_debug: Variant = config.get_value("Settings", "enable_debug_logging") + if loaded_debug is bool: + settings.enable_debug_logging = loaded_debug + log_message( + "Loaded saved debug logging: " + str(settings.enable_debug_logging), + LogLevel.DEBUG + ) + elif err == ERR_FILE_NOT_FOUND: log_message("No settings config found, using defaults.", LogLevel.DEBUG) else: @@ -188,6 +199,8 @@ func _save_settings(path: String = Settings.CONFIG_PATH) -> void: config.set_value("Settings", "log_level", settings.current_log_level) config.set_value("Settings", "difficulty", settings.difficulty) + # NEW: Persist the debug logging flag + config.set_value("Settings", "enable_debug_logging", settings.enable_debug_logging) err = config.save(path) if err != OK: log_message("Failed to save settings: " + str(err), LogLevel.ERROR) diff --git a/test/gut/test_settings_observer.gd b/test/gut/test_settings_observer.gd index d9b05fe10..10a87d555 100644 --- a/test/gut/test_settings_observer.gd +++ b/test/gut/test_settings_observer.gd @@ -118,3 +118,39 @@ func test_ui_slider_syncs_with_resource() -> void: Globals.settings.difficulty = 1.8 # Change resource directly assert_eq(gameplay_menu.difficulty_slider.value, 1.8, "UI Slider should update automatically.") + + +## PHASE 6: Debug Logging Persistence +func test_enable_debug_logging_emits_signal() -> void: + watch_signals(_resource) + _resource.enable_debug_logging = true + + assert_signal_emitted_with_parameters(_resource, "setting_changed", ["enable_debug_logging", true], 0) + +func test_enable_debug_logging_persists_to_disk() -> void: + # Connect signal to the test path for verification + _resource.setting_changed.connect( + func(_k: String, _v: Variant) -> void: + Globals._save_settings(_test_config_path) + ) + + # Act: Toggle the flag + _resource.enable_debug_logging = true + + # Assert: Verify file contents + var config := ConfigFile.new() + var err := config.load(_test_config_path) + assert_eq(err, OK, "Config file should be created for debug_logging change.") + assert_eq(config.get_value("Settings", "enable_debug_logging"), true, "Flag should persist as true.") + +func test_enable_debug_logging_restores_from_disk() -> void: + # Setup: Manually create a config with the flag enabled + var config := ConfigFile.new() + config.set_value("Settings", "enable_debug_logging", true) + config.save(_test_config_path) + + # Act: Load via Globals logic + Globals._load_settings(_test_config_path) + + # Assert: Resource should now match the disk state + assert_eq(_resource.enable_debug_logging, true, "Resource should reflect loaded debug flag.")
