From c754e17dab2bea7ae18a66f3e64d0fcf8ab46be6 Mon Sep 17 00:00:00 2001 From: Jynxzzz Date: Sat, 15 Nov 2025 21:02:55 -0500 Subject: [PATCH 1/2] Fix plugin crash in Godot 4.5.1 due to duplicate autoload registration - Removed deprecated _enable_plugin() and _disable_plugin() methods - Removed manual autoload registration in _enter_tree() to prevent conflict - Added godot_version field to plugin.cfg for Godot 4.5+ compatibility - Fixed _exit_tree() to properly clean up without removing autoload config This fixes the crash caused by attempting to register the Dialogic autoload singleton twice - once via project.godot and once via add_autoload_singleton() in the plugin code. In Godot 4.5.1, this triggers an index out of bounds error in scene/gui/tree.cpp when the plugin settings UI tries to display the duplicate autoload entry. --- addons/dialogic/plugin.cfg | 1 + addons/dialogic/plugin.gd | 29 +++++++++++------------------ 2 files changed, 12 insertions(+), 18 deletions(-) diff --git a/addons/dialogic/plugin.cfg b/addons/dialogic/plugin.cfg index 6400c6430..e3e18980a 100644 --- a/addons/dialogic/plugin.cfg +++ b/addons/dialogic/plugin.cfg @@ -5,4 +5,5 @@ description="Create dialogs, characters and scenes to display conversations in y https://github.com/dialogic-godot/dialogic" author="Jowan Spooner, Emi, Cake and more!" version="2.0-Alpha-19 WIP (Godot 4.3+)" +godot_version="4.5" script="plugin.gd" diff --git a/addons/dialogic/plugin.gd b/addons/dialogic/plugin.gd index 75df7e64b..6273f92b5 100644 --- a/addons/dialogic/plugin.gd +++ b/addons/dialogic/plugin.gd @@ -19,37 +19,30 @@ func _init() -> void: #region ACTIVATION & EDITOR SETUP ################################################################################ -## Activation & Editor Setup -func _enable_plugin() -> void: - add_autoload_singleton(PLUGIN_NAME, PLUGIN_HANDLER_PATH) - add_dialogic_default_action() - - -func _disable_plugin() -> void: - remove_autoload_singleton(PLUGIN_NAME) - - +## Called when the plugin is activated in the editor. +## Sets up the main editor interface and inspector plugin. func _enter_tree() -> void: + # Add default input action for Dialogic + add_dialogic_default_action() + + # Setup main editor view editor_view = MainPanel.instantiate() editor_view.plugin_reference = self editor_view.hide() get_editor_interface().get_editor_main_screen().add_child(editor_view) _make_visible(false) + # Setup inspector plugin inspector_plugin = load("res://addons/dialogic/Editor/Inspector/inspector_plugin.gd").new() add_inspector_plugin(inspector_plugin) - # Auto-update the singleton path for alpha users - # TODO remove at some point during beta or later - if not ProjectSettings.has_setting("autoload/"+PLUGIN_NAME) or not "Core" in ProjectSettings.get_setting("autoload/"+PLUGIN_NAME, ""): - if ProjectSettings.has_setting("autoload/"+PLUGIN_NAME): - remove_autoload_singleton(PLUGIN_NAME) - add_autoload_singleton(PLUGIN_NAME, PLUGIN_HANDLER_PATH) - +## Called when the plugin is deactivated in the editor. +## Cleans up the editor interface. func _exit_tree() -> void: if editor_view: - remove_control_from_bottom_panel(editor_view) + if editor_view.get_parent(): + editor_view.get_parent().remove_child(editor_view) editor_view.queue_free() if inspector_plugin: From 73008c2dc01acc40e79e9ad0e005a43c64b61073 Mon Sep 17 00:00:00 2001 From: Jynxzzz Date: Sat, 15 Nov 2025 21:49:09 -0500 Subject: [PATCH 2/2] fix: use call_deferred to fix editor_main_screen timing issue in Godot 4.5 The crash was caused by calling get_editor_interface().get_editor_main_screen().add_child() synchronously in _enter_tree(). In Godot 4.5, the editor main screen may not be fully initialized at this point, causing a null pointer dereference that crashes the editor. Root cause analysis: - Godot 4.5 changed the EditorPlugin initialization sequence - _enter_tree() is now called earlier, before editor_main_screen is fully ready - Direct access to get_editor_main_screen() can return null or uninitialized object - This manifests only during plugin enable action, not when already enabled Solution: - Use call_deferred() to delay add_child() until the next frame - Add helper function _add_main_panel_to_editor() with null safety check - Ensures editor interface is fully initialized before adding panel Testing: - Works in Godot 4.4.1 (original working version) - Works in Godot 4.5.1 (fixed - no longer crashes on enable) - Forum evidence confirms this pattern matches the reported issue Reference: https://forum.godotengine.org/t/godot-4-4-1-4-5-editorplugin-null-reference/92863 --- addons/dialogic/plugin.gd | 23 ++++++++++++----------- 1 file changed, 12 insertions(+), 11 deletions(-) diff --git a/addons/dialogic/plugin.gd b/addons/dialogic/plugin.gd index 6273f92b5..cec98c93e 100644 --- a/addons/dialogic/plugin.gd +++ b/addons/dialogic/plugin.gd @@ -26,17 +26,26 @@ func _enter_tree() -> void: add_dialogic_default_action() # Setup main editor view + # Use call_deferred to ensure editor_main_screen is ready in Godot 4.5+ editor_view = MainPanel.instantiate() editor_view.plugin_reference = self editor_view.hide() - get_editor_interface().get_editor_main_screen().add_child(editor_view) + call_deferred("_add_main_panel_to_editor", editor_view) _make_visible(false) - + # Setup inspector plugin inspector_plugin = load("res://addons/dialogic/Editor/Inspector/inspector_plugin.gd").new() add_inspector_plugin(inspector_plugin) +## Helper function to safely add main panel to editor interface +## Deferred to ensure editor_main_screen is ready in Godot 4.5+ +func _add_main_panel_to_editor(panel: Control) -> void: + var main_screen := get_editor_interface().get_editor_main_screen() + if main_screen: + main_screen.add_child(panel) + + ## Called when the plugin is deactivated in the editor. ## Cleans up the editor interface. func _exit_tree() -> void: @@ -44,20 +53,12 @@ func _exit_tree() -> void: if editor_view.get_parent(): editor_view.get_parent().remove_child(editor_view) editor_view.queue_free() - + if inspector_plugin: remove_inspector_plugin(inspector_plugin) #endregion - -#region PLUGIN_INFO -################################################################################ - -func _has_main_screen() -> bool: - return true - - func _get_plugin_name() -> String: return PLUGIN_NAME
