• Fix JavaScript code blocks creating layout shifts ("jumps") when scrolling Events Sheet
• Fix corrupted display of instance when dragging an object back to the objects list in custom object editor

💝 Improvements

• Add "syntax highlighting" for expressions in Events Sheet: complex expressions and formula will now be shown using multiple colors, like the rest of events. This allows to identify objects, numbers, strings in a long formula.

  

• UI improvements:

  • Add "Select All" in Events Sheet and ability to deselect an event when doing a multi-selection (Thanks @ViktorVovk!)
  • Hide deprecated extensions in new projects
  • Make the function extractor dialog more compact
  • Allow to install extensions from the action or condition search
  • Automatically choose a function name in the function extraction dialog

    • Allow to add behaviors from the bottom of the instruction list

• Extensions improvements:

  • Allow custom objects to move layer cameras
  • Add a "layer" property type for custom behaviors

• Experimental resource loading improvements: allow to load and unload objects from other scenes.

• Improve a lot the time to launch previews (and other operations like modifying groups/renaming objects) when using very long expressions

• New icons for premium subscribers on the forum and Discord:

  • A new role is now shown for Silver subscribers on Discord.
  • A subscriber icon (Silver, Gold, Pro, Education) is now visible on your forum account, if you use the same email between your GDevelop and the forum.

• Add argument for CLI command execution for CI pipelines (Thanks @malec-palec!)

  • Add --run-command CLI flag that executes any Command Palette command after loading a project.
    In CLI mode all blocking dialogs (autosave, changelog, confirmations) are auto-resolved, the window is hidden, and the process exits with a meaningful exit code.
  • This enables CI pipelines to run exports (e.g. EXPORT_HTML5_EXTERNAL) using only the editor distribution - no installation or display required.

⚙️ Extensions

• [Experimental] [3D foliage swaying] Sway foliage of 3D objects according to wind (thanks @baldieandbaldie-commits)

  

  This extension adds wind swaying ability and optional GPU instancing to 3D objects (trees, grass, bushes) with frustum and distance culling. This is an advanced extension and while a lightweight example will be made later, you can for now try the full example by downloading it on the GitHub thread of the extension.

  It comes with:

  • Real-time foliage wind animation for 3D scenes
  • Multiple sway types: Grass, Bush, Tree Trunk (dead tree), and Tree Leaves (more coming soon)
  • Works with both regular meshes and GPU-instanced foliage for better performance
  • Global wind controls: strength, speed, and wind direction
  • Optional gust system with texture-driven gust masks
  • Optional visual tuning: gradient tint, saturation/contrast, PBR tweaks
  • Distance-based fading/culling for better performance
  • Automatic foliage shader/material patching (including shadow materials)
  • Runtime-safe live updates for wind/gust parameters
  • Scene/object cleanup logic to reduce memory leaks and stale resources

• [Reviewed] [Fire bullet] New behavior for firing bullets in 3D games.

💡 New 3D Spot Light and Point Light objects

3D lights can now be used with the new "3D spot light" and "3D point light" objects! You can find them in the "New Object" dialog. Check out the documentation here.

Light objects can be demanding on the GPU, especially when they cast shadows. To allow to add many lights to a scene, the engine automatically hides the lights farthest from the camera. By default, the limits are 20 visible light objects and 4 light objects casting shadows (the closest to the camera). Read more in the documentation.

💝 Improvements

• Reworked events sheet design (thanks @LuniMoon!):
  • Colors adjusted to match accessibility standards,
  • Refined borders around conditions/actions
  • Handles of comments/groups are colored as the event itself,
  • Spacing, borders and other tweaks.
• Fix default variable string value being "0" instead of empty:
  • Before, variable were set to the string "0" even though displaying as empty in the list of variables.
  • Projects created before 5.6.267 will keep the same behavior (0 as default value for string variables) with an option to upgrade to the new behavior in the project properties dialog. This allows previous projects to keep backward compatibility and not break. It's recommended to activate this option and check that your game continues to work as soon as you can (keep a backup in case you want to upgrade later).
  • Projects created from 5.6.267 will use the new default behavior (empty as default value).
• Improve 2D lights collision calculation for better performance.
• Add expressions to access the components of forward/up/right vectors of 3D objects
  • These are advanced expressions mostly useful for extensions manipulating objects in 3D space.
• Add experimental configuration to allow object resources to be loaded independently from the scene.
  • This is an advanced, experimental feature which is subject to changes. It's in most cases not useful, unless you have a large game or low end devices for which controlling memory usage is important. It's mostly useful to delay loading of large custom objects.
  • Objects can be configured so that its resources are not loaded when the scene is loaded. Instead, you can use an action to manually load the resources used by it. When the loading is finished (this can be checked using a condition), the object can then be created. Read the documentation to learn more.
  • Be careful: if an object assets are not loaded before being created, it will be broken when displayed on screen.
• Improve premium courses structure.
• Add editor lifecycle hooks for auto running npm scripts (rhanks @ViktorVovk!). See documentation here.
  • Three hooks are implemented: onEditorReady, onPreviewStart, onPreviewEnd.
  • Auto-execution of hooked scripts requires user consent.
• Improve handling of devices with both a mouse and touchscreen so GDevelop can be controlled both ways in one session
• Improve desktop app updater messages and actions
  • Regularly check for updates, not only on launch
  • When update is downloaded, notification to restart & install
  • also display version number in notification

🪟 Experimental option to open editors in separate windows

Right clicking on a tab now displays an option to detach a tab into a separate window (both on the desktop app and the web-app).

This enables to work on events sheet, extensions or other parts of a game without switching between tabs. It's also perfect for multi-monitor displays.

• ⚠️ This is an experimental feature: some part of the editor might not be fully ready for changes to be done in another window. In case of crash or suspicious behavior when using a tab, please report the issue on the forum or Discord and re-open the editor.
  Make sure to do regular backups of your game as with any experimental feature.

• Limitation: it works for Events Sheets, Extensions, Global Search, Resources but not for scene editors which must stay in the main window at this time.

• Fix tentatively crashes at scene editor resize

💝 Improvements

• Extend the Diagnostic Report to cover events in extensions (thanks @malec-palec!)
  • The Diagnostic Report previously only scanned scene events and external events for validation errors. It now also reports issues in events inside extension functions - including top-level ("free") functions, behavior functions, and object functions - detecting missing instructions and invalid parameters.
  • Store-installed extensions are excluded from the scan
  • Disabled ("commented out") events and their sub-events are not reported anymore (as they don't impact the game).

💝 Improvements

• Introduce Global Search, allowing to search in all Events Sheets (including extensions) (thanks @ViktorVovk!)
  • Global Search can be opened using Ctrl+Shift+F (or Cmd+Shift+F). The shortcut works from any editor, even if the Global Search is already opened, allowing to quickly launch a new search.
  • Click on any search result to open the corresponding events sheet with the result(s) highlighted.
  • By default, extensions from the store are excluded from results. You can change this in the filters.

• Upgrade to React 18
• Add "MemoryTracked" classes and "UseAfterFreeError"
  • This will track alive/dead instances of some C++ classes and will throw a JS error in case of usage of a already destroyed object from JavaScript. This should avoid crashing/corrupting the wasm/C++ side by calling a method on an object already destroyed. Instead the exception stays on JS side, without reaching the C++ implementation.
• Add "internal instruction name" search criterion in Events Sheet search panel (thanks @ViktorVovk!)
