Upgrading from Godot 4.4 to Godot 4.5

For most games and apps made with 4.4 it should be relatively safe to migrate to 4.5. This page intends to cover everything you need to pay attention to when migrating your project.

破壊的変更

If you are migrating from 4.4 to 4.5, the breaking changes listed here might affect you. Changes are grouped by areas/systems.

警告

In order to support new Google Play requirements Android now requires targeting .NET 9 when exporting C# projects to Android, other platforms continue to use .NET 8 as the minimum required version but newer versions are supported and encouraged.

If you are using C# in your project and want to export to Android, you will need to upgrade your project to .NET 9 (see Upgrading to a new .NET version for instructions).

この記事では、各破壊的変更がGDScriptに影響するかどうか、またC#の破壊的変更が バイナリ互換 なのか ソース互換 なのかを示します:

• Binary compatible - Existing binaries will load and execute successfully without recompilation, and the run-time behavior won't change.

• ソース互換: Godotをアップグレードしてもソースコードの変更なしでコンパイルに成功します。

注釈

In C#, the enum RenderingDevice.Features breaks compatibility because of the way the bindings generator detects the enum prefix. New members were added to the enum in GH-103941 that caused the enum member Address to be renamed to BufferDeviceAddress.

注釈

Classes OpenXRBindingModifierEditor, OpenXRInteractionProfileEditor, and OpenXRInteractionProfileEditorBase are only available in the editor. Using them outside of the editor will result in a compilation error.

In C#, this means the types are moved from the GodotSharp assembly to the GodotSharpEditor assembly. Make sure to wrap code that uses these types in a #if TOOLS block to ensure they are not included in an exported game.

This change was also backported to 4.4.1.

Behavior changes

In 4.5, some behavior changes have been introduced, which might require you to adjust your project.

TileMapLayer

TileMapLayer.get_coords_for_body_rid() will return different values in 4.5 compared to 4.4, as TileMapLayer physics chunking is enabled by default. Higher values of TileMapLayer.physics_quadrant_size will make this function less precise. To get the exact cell coordinates like in 4.4 and prior versions, you need to set TileMapLayer.physics_quadrant_size to 1, which disables physics chunking.

3D Model Import

A fix has been made to the 3D model importers to correctly handle non-joint nodes within a skeleton hierarchy (GH-104184). To preserve compatibility, the default behavior is to import existing files with the same behavior as before (GH-107352). New .gltf, .glb, .blend, and .fbx files (without a corresponding .import file) will be imported with the new behavior. However, for existing files, if you want to use the new behavior, you must change the "Naming Version" option at the bottom of the Import dock:

Core

注釈

Resource.duplicate(true) (which performs deep duplication) now only duplicates resources internal to the resource file it's called on. In 4.4, this duplicated everything instead, including external resources. If you were deep-duplicating a resource that contained references to other external resources, those external resources aren't duplicated anymore. You must call Resource.duplicate_deep(RESOURCE_DEEP_DUPLICATE_ALL) instead to keep the old behavior.

注釈

ProjectSettings.add_property_info() now prints a warning when the dictionary parameter has missing keys or invalid keys. Most importantly, it will now warn when a usage key is passed, as this key is not used. This was also the case before 4.5, but it was silently ignored instead. As a reminder, to set property usage information correctly, you must use ProjectSettings.set_as_basic(), ProjectSettings.set_restart_if_changed(), or ProjectSettings.set_as_internal() instead.

注釈

In C#, StringExtensions.PathJoin now avoids adding an extra path separator when the original string is empty, or when the appended path starts with a path separator (GH-105281).

注釈

In C#, StringExtensions.GetExtension now returns an empty string instead of the original string when the original string does not contain an extension (GH-108041).

注釈

In C#, the Quaternion(Vector3, Vector3) constructor now correctly creates a quaternion representing the shortest arc between the two input vectors. Previously, it would return incorrect values for certain inputs (GH-107618).

ナビゲーション

注釈

By default, the regions in a NavigationServer map now update asynchronously using threads to improve performance. This can cause additional delay in the update due to thread synchronisation. The asynchronous region update can be toggled with the navigation/world/region_use_async_iterations project setting.

注釈

The merging of navmeshes in the NavigationServer has changed processing order. Regions now merge and cache internal navmeshes first, then the remaining free edges are merged by the navigation map. If a project had navigation map synchronisation errors before, it might now have shifted affected edges, making already existing errors in a layout more noticeable in the pathfinding. The navigation/2d_or_3d/merge_rasterizer_cell_scale project setting can be set to a lower value to increase the detail of the rasterization grid (with 0.01 being the smallest cell size possible). If edge merge errors still persist with the lowest possible rasterization scale value, the error may be caused by overlap: two navmeshes are stacked on top of each other, causing geometry conflict.

物理

注釈

When the 3D physics engine is set to Jolt Physics, you will now always have overlaps between Area3D and static bodies reported by default, as the physics/jolt_physics_3d/simulation/areas_detect_static_bodies project setting has been removed (GH-105746). If you still want such overlaps to be ignored, you will need to change the collision mask or layer of either the Area3D or the static body instead.

Text

注釈

In GDScript, calls to functions RichTextLabel::add_image and RichTextLabel::update_image will continue to work, but the size_in_percent argument will now be used as the value for width_in_percent and height_in_percent will default to false (GH-107347). To restore the previous behavior, you can explicitly set height_in_percent to the same value you were passing as size_in_percent.
