Contains global variables accessible from everywhere. Contains global variables accessible from everywhere. Use [method get_setting], [method set_setting] or [method has_setting] to access them. Variables stored in [code]project.godot[/code] are also loaded into ProjectSettings, making this object very useful for reading custom game configuration options. When naming a Project Settings property, use the full path to the setting including the category. For example, [code]"application/config/name"[/code] for the project name. Category and property names can be viewed in the Project Settings dialog. [b]Overriding:[/b] Any project setting can be overridden by creating a file named [code]override.cfg[/code] in the project's root directory. This can also be used in exported projects by placing this file in the same directory as the project binary. Adds a custom property info to a property. The dictionary must contain: - [code]name[/code]: [String] (the property's name) - [code]type[/code]: [int] (see [enum Variant.Type]) - optionally [code]hint[/code]: [int] (see [enum PropertyHint]) and [code]hint_string[/code]: [String] [b]Example:[/b] [codeblock] ProjectSettings.set("category/property_name", 0) var property_info = { "name": "category/property_name", "type": TYPE_INT, "hint": PROPERTY_HINT_ENUM, "hint_string": "one,two,three" } ProjectSettings.add_property_info(property_info) [/codeblock] Clears the whole configuration (not recommended, may break things). Returns the order of a configuration value (influences when saved to the config file). Returns the value of a setting. [b]Example:[/b] [codeblock] print(ProjectSettings.get_setting("application/config/name")) [/codeblock] Converts a localized path ([code]res://[/code]) to a full native OS path. Returns [code]true[/code] if a configuration value is present. Loads the contents of the .pck or .zip file specified by [code]pack[/code] into the resource filesystem ([code]res://[/code]). Returns [code]true[/code] on success. [b]Note:[/b] If a file from [code]pack[/code] shares the same path as a file already in the resource filesystem, any attempts to load that file will use the file from [code]pack[/code] unless [code]replace_files[/code] is set to [code]false[/code]. Convert a path to a localized path ([code]res://[/code] path). Returns [code]true[/code] if the specified property exists and its initial value differs from the current value. Returns the specified property's initial value. Returns [code]null[/code] if the property does not exist. Saves the configuration to the [code]project.godot[/code] file. Saves the configuration to a custom file. Sets the specified property's initial value. This is the value the property reverts to. Sets the order of a configuration value (influences when saved to the config file). Sets the value of a setting. [b]Example:[/b] [codeblock] ProjectSettings.set_setting("application/config/name", "Example") [/codeblock] Comma-separated list of custom Android modules (which must have been built in the Android export templates) using their Java package path, e.g. [code]org/godotengine/org/GodotPaymentV3,org/godotengine/godot/MyCustomSingleton"[/code]. Background color for the boot splash. If [code]true[/code], scale the boot splash image to the full window length when engine starts. If [code]false[/code], the engine will leave it at the default pixel size. Path to an image used as the boot splash. If [code]true[/code], applies linear filtering when scaling the image (recommended for high resolution artwork). If [code]false[/code], uses nearest-neighbor interpolation (recommended for pixel art). This user directory is used for storing persistent data ([code]user://[/code] filesystem). If left empty, [code]user://[/code] resolves to a project-specific folder in Godot's own configuration folder (see [method OS.get_user_data_dir]). If a custom directory name is defined, this name will be used instead and appended to the system-specific user data directory (same parent folder as the Godot configuration folder documented in [method OS.get_user_data_dir]). The [member application/config/use_custom_user_dir] setting must be enabled for this to take effect. The project's description, displayed as a tooltip in the Project Manager when hovering the project. Icon used for the project, set when project loads. Exporters will also use this icon when possible. Icon set in [code].icns[/code] format used on macOS to set the game's icon. This is done automatically on start by calling [method OS.set_native_icon]. The project's name. It is used both by the Project Manager and by exporters. The project name can be translated by translating its value in localization files. Specifies a file to override project settings. For example: [code]user://custom_settings.cfg[/code]. [b]Note:[/b] Regardless of this setting's value, [code]res://override.cfg[/code] will still be read to override the project settings (see this class' description at the top). If [code]true[/code], the project will save user data to its own user directory (see [member application/config/custom_user_dir_name]). This setting is only effective on desktop platforms. A name must be set in the [member application/config/custom_user_dir_name] setting for this to take effect. If [code]false[/code], the project will save user data to [code](OS user data directory)/Godot/app_userdata/(project name)[/code]. Icon set in [code].ico[/code] format used on Windows to set the game's icon. This is done automatically on start by calling [method OS.set_native_icon]. If [code]true[/code], disables printing to standard error in an exported build. If [code]true[/code], disables printing to standard output in an exported build. Forces a delay between frames in the main loop (in milliseconds). This may be useful if you plan to disable vertical synchronization. If [code]true[/code], enables low-processor usage mode. This setting only works on desktop platforms. The screen is not redrawn if nothing changes visually. This is meant for writing applications and editors, but is pretty useless (and can hurt performance) in most games. Amount of sleeping between frames when the low-processor usage mode is enabled (in microseconds). Higher values will result in lower CPU usage. Path to the main scene file that will be loaded when the project runs. Audio buses will disable automatically when sound goes below a given dB threshold for a given time. This saves CPU as effects assigned to that bus will no longer do any processing. Audio buses will disable automatically when sound goes below a given dB threshold for a given time. This saves CPU as effects assigned to that bus will no longer do any processing. Default [AudioBusLayout] resource file to use in the project, unless overridden by the scene. Specifies the audio driver to use. This setting is platform-dependent as each platform supports different audio drivers. If left empty, the default audio driver will be used. If [code]true[/code], microphone input will be allowed. This requires appropriate permissions to be set when exporting to Android or iOS. Mixing rate used for audio. In general, it's better to not touch this and leave it to the host operating system. Output latency in milliseconds for audio. Lower values will result in lower audio latency at the cost of increased CPU usage. Low values may result in audible cracking on slower hardware. Setting to hardcode audio delay when playing video. Best to leave this untouched unless you know what you are doing. Default compression level for gzip. Affects compressed scenes and resources. Default compression level for Zlib. Affects compressed scenes and resources. Default compression level for Zstandard. Affects compressed scenes and resources. Enables long-distance matching in Zstandard. Largest size limit (in power of 2) allowed when compressing using long-distance matching with Zstandard. If [code]true[/code], displays getters and setters in autocompletion results in the script editor. This setting is meant to be used when porting old projects (Godot 2), as using member variables is the preferred style from Godot 3 onwards. If [code]true[/code], enables warnings when a constant is used as a function. If [code]true[/code], enables warnings when deprecated keywords are used. If [code]true[/code], enables specific GDScript warnings (see [code]debug/gdscript/warnings/*[/code] settings). If [code]false[/code], disables all GDScript warnings. If [code]true[/code], scripts in the [code]res://addons[/code] folder will not generate warnings. If [code]true[/code], enables warnings when a function is declared with the same name as a constant. If [code]true[/code], enables warnings when a function is declared with the same name as a variable. This will turn into an error in a future version when first-class functions become supported in GDScript. If [code]true[/code], enables warnings when a function assigned to a variable may yield and return a function state instead of a value. If [code]true[/code], enables warnings when using a function as if it was a property. If [code]true[/code], enables warnings when a ternary operator may emit values with incompatible types. If [code]true[/code], enables warnings when dividing an integer by another integer (the decimal part will be discarded). If [code]true[/code], enables warnings when passing a floating-point value to a function that expects an integer (it will be converted and lose precision). If [code]true[/code], enables warnings when using a property as if it was a function. If [code]true[/code], enables warnings when calling a function without using its return value (by assigning it to a variable or using it as a function argument). Such return values are sometimes used to denote possible errors using the [enum Error] enum. If [code]true[/code], enables warnings when defining a local or subclass member variable that would shadow a variable at an upper level (such as a member variable). If [code]true[/code], enables warnings when calling an expression that has no effect on the surrounding code, such as writing [code]2 + 2[/code] as a statement. If [code]true[/code], enables warnings when calling a ternary expression that has no effect on the surrounding code, such as writing [code]42 if active else 0[/code] as a statement. If [code]true[/code], all warnings will be reported as if they were errors. If [code]true[/code], enables warnings when using a variable that wasn't previously assigned. If [code]true[/code], enables warnings when assigning a variable using an assignment operator like [code]+=[/code] if the variable wasn't previously assigned. If [code]true[/code], enables warnings when unreachable code is detected (such as after a [code]return[/code] statement that will always be executed). If [code]true[/code], enables warnings when using an expression whose type may not be compatible with the function parameter expected. If [code]true[/code], enables warnings when performing an unsafe cast. If [code]true[/code], enables warnings when calling a method whose presence is not guaranteed at compile-time in the class. If [code]true[/code], enables warnings when accessing a property whose presence is not guaranteed at compile-time in the class. If [code]true[/code], enables warnings when a function parameter is unused. If [code]true[/code], enables warnings when a member variable is unused. If [code]true[/code], enables warnings when a signal is unused. If [code]true[/code], enables warnings when a local variable is unused. If [code]true[/code], enables warnings when a variable is declared with the same name as a function. This will turn into an error in a future version when first-class functions become supported in GDScript. If [code]true[/code], enables warnings when assigning the result of a function that returns [code]void[/code] to a variable. Message to be displayed before the backtrace when the engine crashes. Maximum number of frames per second allowed. The actual number of frames per second may still be below this value if the game is lagging. If [member display/window/vsync/use_vsync] is enabled, it takes precedence and the forced FPS number cannot exceed the monitor's refresh rate. This setting is therefore mostly relevant for lowering the maximum FPS below VSync, e.g. to perform non real-time rendering of static frames, or test the project under lag conditions. Maximum call stack allowed for debugging GDScript. Maximum amount of functions per frame allowed when profiling. Print frames per second to standard output every second. Print more information to standard output when running. It displays information such as memory leaks, which scenes and resources are being loaded, etc. Maximum call stack in visual scripting, to avoid infinite recursion. Color of the contact points between collision shapes, visible when "Visible Collision Shapes" is enabled in the Debug menu. Maximum number of contact points between collision shapes to display when "Visible Collision Shapes" is enabled in the Debug menu. Color of the collision shapes, visible when "Visible Collision Shapes" is enabled in the Debug menu. Color of the disabled navigation geometry, visible when "Visible Navigation" is enabled in the Debug menu. Color of the navigation geometry, visible when "Visible Navigation" is enabled in the Debug menu. Custom image for the mouse cursor (limited to 256×256). Hotspot for the custom mouse cursor image. Position offset for tooltips, relative to the mouse cursor's hotspot. If [code]true[/code], allows HiDPI display on Windows and macOS. This setting has no effect on desktop Linux, as DPI-awareness fallbacks are not supported there. If [code]true[/code], keeps the screen on (even in case of inactivity), so the screensaver does not take over. Works on desktop and mobile platforms. Default orientation on mobile devices. If [code]true[/code], the home indicator is hidden automatically. This only affects iOS devices without a physical home button. If [code]true[/code], allows per-pixel transparency in a desktop window. This affects performance, so leave it on [code]false[/code] unless you need it. Sets the window background to transparent when it starts. Force the window to be always on top. Force the window to be borderless. Sets the window to full screen when it starts. Sets the game's main viewport height. On desktop platforms, this is the default window size. Stretch mode settings also use this as a reference when enabled. Allows the window to be resizable by default. If greater than zero, overrides the window height when running the game. Useful for testing stretch modes. If greater than zero, overrides the window width when running the game. Useful for testing stretch modes. Sets the game's main viewport width. On desktop platforms, this is the default window size. Stretch mode settings also use this as a reference when enabled. If [code]true[/code], enables vertical synchronization. This eliminates tearing that may appear in moving scenes, at the cost of higher input latency and stuttering at lower framerates. If [code]false[/code], vertical synchronization will be disabled, however, many platforms will enforce it regardless (such as mobile platforms and HTML5). If [code]Use Vsync[/code] is enabled and this setting is [code]true[/code], enables vertical synchronization via the operating system's window compositor when in windowed mode and the compositor is enabled. This will prevent stutter in certain situations. (Windows only.) [b]Note:[/b] This option is experimental and meant to alleviate stutter experienced by some users. However, some users have experienced a Vsync framerate halving (e.g. from 60 FPS to 30 FPS) when using it. Search path for project-specific script templates. Script templates will be search both in the editor-specific path and in this project-specific path. Text-based file extensions to include in the script editor's "Find in Files" feature. You can add e.g. [code]tscn[/code] if you wish to also parse your scene files, especially if you use built-in scripts which are serialized in the scene files. Default value for [member ScrollContainer.scroll_deadzone], which will be used for all [ScrollContainer]s unless overridden. If [code]true[/code], swaps OK and Cancel buttons in dialogs on Windows and UWP to follow interface conventions. Path to a custom [Theme] resource file to use for the project ([code]theme[/code] or generic [code]tres[/code]/[code]res[/code] extension). Path to a custom [Font] resource to use as default for all GUI elements of the project. If [code]true[/code], makes sure the theme used works with HiDPI. Timer setting for incremental search in [Tree], [ItemList], etc. controls (in milliseconds). Timer for detecting idle in [TextEdit] (in seconds). Default delay for tooltips (in seconds). Default [InputEventAction] to confirm a focused button, menu or list item, or validate input.

The locale to fall back to if a translation isn't available in a given language. If left empty, [code]en[/code] (English) will be used. If non-empty, this locale will be used when running the project from the editor. If [code]true[/code], logs all output to files. Path to logs within the project. Using an [code]user://[/code] path is recommended. Specifies the maximum amount of log files allowed (used for rotation). Godot uses a message queue to defer some function calls. If you run out of space on it (you will see an error), you can increase the size here. This is used by servers when used in multi-threading mode (servers and visual). RIDs are preallocated to avoid stalling the server requesting them on threads. If servers get stalled too often when loading resources in a thread, increase this number. Maximum amount of characters allowed to send as output from the debugger. Over this value, content is dropped. This helps not to stall the debugger connection. Maximum number of errors allowed to be sent as output from the debugger. Over this value, content is dropped. This helps not to stall the debugger connection.

See [constant Physics2DServer.SPACE_PARAM_BODY_ANGULAR_VELOCITY_SLEEP_THRESHOLD]. Threshold linear velocity under which a 2D physics body will be considered inactive. See [constant Physics2DServer.SPACE_PARAM_BODY_LINEAR_VELOCITY_SLEEP_THRESHOLD]. Sets whether physics is run on the main thread or a separate one. Running the server on a thread increases performance, but restricts API access to only physics process. [b]Warning:[/b] As of Godot 3.2, there are mixed reports about the use of a Multi-Threaded thread model for physics. Be sure to assess whether it does give you extra performance and no regressions when using it. Time (in seconds) of inactivity before which a 2D physics body will put to sleep. See [constant Physics2DServer.SPACE_PARAM_BODY_TIME_TO_SLEEP]. Sets whether the 3D physics world will be created with support for [SoftBody] physics. Only applies to the Bullet physics engine. The default angular damp in 3D. The default gravity strength in 3D. [b]Note:[/b] This property is only read when the project starts. To change the default gravity at runtime, use the following code sample: [codeblock] # Set the default gravity strength to 9.8.

Sets which physics engine to use for 3D physics. "DEFAULT" is currently the [url=https://bulletphysics.org]Bullet[/url] physics engine. The "GodotPhysics" engine is still supported as an alternative. Enables [member Viewport.physics_object_picking] on the root viewport. The number of fixed iterations per second. This controls how often physics simulation and [method Node._physics_process] methods are run. [b]Note:[/b] This property is only read when the project starts. To change the physics FPS at runtime, set [member Engine.iterations_per_second] instead. Fix to improve physics jitter, specially on monitors where refresh rate is different than the physics FPS. [b]Note:[/b] This property is only read when the project starts. To change the physics FPS at runtime, set [member Engine.physics_jitter_fix] instead. Default background clear color. Overridable per [Viewport] using its [Environment]. See [member Environment.background_mode] and [member Environment.background_color] in particular. To change this default color programmatically, use [method VisualServer.set_default_clear_color]. [Environment] that will be used as a fallback environment in case a scene does not specify its own environment. The default environment is loaded in at scene load time regardless of whether you have set an environment or not. If you do not rely on the fallback environment, it is best to delete [code]default_env.tres[/code], or to specify a different default environment here. Max amount of elements renderable in a frame. If more than this are visible per frame, they will be dropped. Keep in mind elements refer to mesh surfaces and not meshes themselves. Some NVIDIA GPU drivers have a bug which produces flickering issues for the [code]draw_rect[/code] method, especially as used in [TileMap]. Refer to [url=https://github.com/godotengine/godot/issues/9913]GitHub issue 9913[/url] for details. If [code]true[/code], this option enables a "safe" code path for such NVIDIA GPUs at the cost of performance. This option only impacts the GLES2 rendering backend, and only desktop platforms. It is not necessary when using the Vulkan backend. If [code]true[/code], forces snapping of polygons to pixels in 2D rendering. May help in some pixel art styles. Disables depth pre-pass for some GPU vendors (usually mobile), as their architecture already does this. If [code]true[/code], performs a previous depth pass before rendering materials. This increases performance in scenes with high overdraw, when complex materials and lighting are used. The directional shadow's size in pixels. Higher values will result in sharper shadows, at the cost of performance. The value will be rounded up to the nearest power of 2. Lower-end override for [member rendering/quality/directional_shadow/size] on mobile devices, due to performance concerns or driver support. The video driver to use ("GLES2" or "Vulkan"). [b]Note:[/b] The backend in use can be overridden at runtime via the [code]--video-driver[/code] command line argument. In such cases, this property is not updated, so use [method OS.get_current_video_driver] to query it at run-time. Sets the number of MSAA samples to use. MSAA is used to reduce aliasing around the edges of polygons. A higher MSAA value results in smoother edges but can be significantly slower on some hardware. [b]Note:[/b] MSAA is not available on HTML5 export using the GLES2 backend. If [code]true[/code], uses nearest-neighbor mipmap filtering when using mipmaps (also called "bilinear filtering"), which will result in visible seams appearing between mipmap stages. This may increase performance in mobile as less memory bandwidth is used. If [code]false[/code], linear mipmap filtering (also called "trilinear filtering") is used. Strategy used for framebuffer allocation. The simpler it is, the less resources it uses (but the less features it supports). If set to "2D Without Sampling" or "3D Without Effects", sample buffers will not be allocated. This means [code]SCREEN_TEXTURE[/code] and [code]DEPTH_TEXTURE[/code] will not be available in shaders and post-processing effects will not be available in the [Environment]. Lower-end override for [member rendering/quality/intended_usage/framebuffer_allocation] on mobile devices, due to performance concerns or driver support. If [code]true[/code], uses texture arrays instead of mipmaps for reflection probes and panorama backgrounds (sky). This reduces jitter noise on reflections, but costs more performance and memory. Lower-end override for [member rendering/quality/reflections/texture_array_reflections] on mobile devices, due to performance concerns or driver support. If [code]true[/code], uses faster but lower-quality Blinn model to generate blurred reflections instead of the GGX model. Lower-end override for [member rendering/quality/shading/force_blinn_over_ggx] on mobile devices, due to performance concerns or driver support. If [code]true[/code], uses faster but lower-quality Lambert material lighting model instead of Burley. Lower-end override for [member rendering/quality/shading/force_lambert_over_burley] on mobile devices, due to performance concerns or driver support. If [code]true[/code], forces vertex shading for all rendering. This can increase performance a lot, but also reduces quality immensely. Can be used to optimize performance on low-end mobile devices. Lower-end override for [member rendering/quality/shading/force_vertex_shading] on mobile devices, due to performance concerns or driver support. Subdivision quadrant size for shadow mapping. See shadow mapping documentation. Subdivision quadrant size for shadow mapping. See shadow mapping documentation. Subdivision quadrant size for shadow mapping. See shadow mapping documentation. Subdivision quadrant size for shadow mapping. See shadow mapping documentation. Size for shadow atlas (used for OmniLights and SpotLights). See documentation. Lower-end override for [member rendering/quality/shadow_atlas/size] on mobile devices, due to performance concerns or driver support. Shadow filter mode. Higher-quality settings result in smoother shadows that flicker less when moving. "Disabled" is the fastest option, but also has the lowest quality. "PCF5" is smoother but is also slower. "PCF13" is the smoothest option, but is also the slowest. Lower-end override for [member rendering/quality/shadows/filter_mode] on mobile devices, due to performance concerns or driver support. Thread model for rendering. Rendering on a thread can vastly improve performance, but synchronizing to the main thread can cause a bit more jitter. If [code]true[/code], the texture importer will import VRAM-compressed textures using the BPTC algorithm. This texture compression algorithm is only supported on desktop platforms, and only when using the Vulkan renderer. If [code]true[/code], the texture importer will import VRAM-compressed textures using the Ericsson Texture Compression algorithm. This algorithm doesn't support alpha channels in textures. If [code]true[/code], the texture importer will import VRAM-compressed textures using the Ericsson Texture Compression 2 algorithm. This texture compression algorithm is only supported when using the Vulkan renderer. If [code]true[/code], the texture importer will import VRAM-compressed textures using the PowerVR Texture Compression algorithm. This texture compression algorithm is only supported on iOS. If [code]true[/code], the texture importer will import VRAM-compressed textures using the S3 Texture Compression algorithm. This algorithm is only supported on desktop platforms and consoles.
