Safety
All types in the Godot API have interior mutability in Rust parlance.
To enforce that the official thread-safety guidelines are
followed, the typestate pattern is used in the Ref
and TRef
smart pointers,
and the Instance
API. The typestate Ownership
in these types tracks whether
ownership is unique, shared, or exclusive to the current thread. For more information,
see the type-level documentation on Ref
.

, mini_sponsors
, gold_donors
, silver_donors
, bronze_donors
}
sourcepub fn get_frames_drawn(&self) -> i64
pub fn get_frames_drawn(&self) -> i64
Returns the total number of frames drawn. On headless platforms, or if the render loop is disabled with --disable-render-loop
via command line, get_frames_drawn
always returns 0
. See get_idle_frames
.
sourcepub fn get_frames_per_second(&self) -> f64
pub fn get_frames_per_second(&self) -> f64
Returns the frames per second of the running game.
sourcepub fn get_idle_frames(&self) -> i64
pub fn get_idle_frames(&self) -> i64
Sample code is GDScript unless otherwise noted.
Returns the total number of frames passed since engine initialization which is advanced on each idle frame, regardless of whether the render loop is enabled. See also get_frames_drawn
and get_physics_frames
.
get_idle_frames
can be used to run expensive logic less often without relying on a Timer
:
func _process(_delta):
if Engine.get_idle_frames() % 2 == 0:
pass # Run expensive logic only once every 2 idle (render) frames here.
sourcepub fn iterations_per_second(&self) -> i64
pub fn iterations_per_second(&self) -> i64
The number of fixed iterations per second. This controls how often physics simulation and [Node._physics_process
][Node::_physics_process] methods are run. This value should generally always be set to 60
or above, as Godot doesn’t interpolate the physics step. As a result, values lower than 60
will look stuttery. This value can be increased to make input more reactive or work around collision tunneling issues, but keep in mind doing so will increase CPU usage. See also target_fps
and [member ProjectSettings.physics/common/physics_fps].
Note: Only 8 physics ticks may be simulated per rendered frame at most. If more than 8 physics ticks have to be simulated per rendered frame to keep up with rendering, the game will appear to slow down (even if delta
is used consistently in physics calculations). Therefore, it is recommended not to increase Engine.iterations_per_second
above 240. Otherwise, the game will slow down when the rendering framerate goes below 30 FPS.
sourcepub fn get_license_info(&self) -> Dictionary
pub fn get_license_info(&self) -> Dictionary
Returns Dictionary of licenses used by Godot and included third party components.
sourcepub fn get_license_text(&self) -> GodotString
pub fn get_license_text(&self) -> GodotString
Returns Godot license text.
sourcepub fn get_physics_frames(&self) -> i64
pub fn get_physics_frames(&self) -> i64
Sample code is GDScript unless otherwise noted.
Returns the total number of frames passed since engine initialization which is advanced on each physics frame. See also get_idle_frames
.
get_physics_frames
can be used to run expensive logic less often without relying on a Timer
:
func _physics_process(_delta):
if Engine.get_physics_frames() % 2 == 0:
pass # Run expensive logic only once every 2 physics frames here.
sourcepub fn get_physics_interpolation_fraction(&self) -> f64
pub fn get_physics_interpolation_fraction(&self) -> f64
Returns the fraction through the current physics tick we are at the time of rendering the frame. This can be used to implement fixed timestep interpolation.
sourcepub fn physics_jitter_fix(&self) -> f64
pub fn physics_jitter_fix(&self) -> f64
Controls how much physics ticks are synchronized with real time. For 0 or less, the ticks are synchronized. Such values are recommended for network games, where clock synchronization matters. Higher values cause higher deviation of the in-game clock and real clock but smooth out framerate jitters. The default value of 0.5 should be fine for most; values above 2 could cause the game to react to dropped frames with a noticeable delay and are not recommended.
Note: For best results, when using a custom physics interpolation solution, the physics jitter fix should be disabled by setting physics_jitter_fix
to 0
.
sourcepub fn get_singleton(
&self,
name: impl Into<GodotString>
) -> Option<Ref<Object, Shared>>
pub fn get_singleton(
&self,
name: impl Into<GodotString>
) -> Option<Ref<Object, Shared>>
Returns a global singleton with given name
. Often used for plugins, e.g. GodotPayment
on Android.
sourcepub fn target_fps(&self) -> i64
pub fn target_fps(&self) -> i64
The desired frames per second. If the hardware cannot keep up, this setting may not be respected. A value of 0 means no limit.
sourcepub fn time_scale(&self) -> f64
pub fn time_scale(&self) -> f64
Controls how fast or slow the in-game clock ticks versus the real life one. It defaults to 1.0. A value of 2.0 means the game moves twice as fast as real life, whilst a value of 0.5 means the game moves at half the regular speed.
sourcepub fn get_version_info(&self) -> Dictionary
pub fn get_version_info(&self) -> Dictionary
Sample code is GDScript unless otherwise noted.
Returns the current engine version information in a Dictionary.
major
- Holds the major version number as an int
minor
- Holds the minor version number as an int
patch
- Holds the patch version number as an int
hex
- Holds the full version number encoded as a hexadecimal int with one byte (2 places) per number (see example below)
status
- Holds the status (e.g. “beta”, “rc1”, “rc2”, … “stable”) as a String
build
- Holds the build name (e.g. “custom_build”) as a String
hash
- Holds the full Git commit hash as a String
year
- Holds the year the version was released in as an int
string
- major
+ minor
+ patch
+ status
+ build
in a single String
The hex
value is encoded as follows, from left to right: one byte for the major, one byte for the minor, one byte for the patch version. For example, “3.1.12” would be 0x03010C
. Note: It’s still an int internally, and printing it will give you its decimal representation, which is not particularly meaningful. Use hexadecimal literals for easy version comparisons from code:
if Engine.get_version_info().hex >= 0x030200:
# Do things specific to version 3.2 or later
else:
# Do things specific to versions before 3.2
sourcepub fn has_singleton(&self, name: impl Into<GodotString>) -> bool
pub fn has_singleton(&self, name: impl Into<GodotString>) -> bool
Returns true
if a singleton with given name
exists in global scope.
sourcepub fn is_editor_hint(&self) -> bool
pub fn is_editor_hint(&self) -> bool
Sample code is GDScript unless otherwise noted.
If true
, the script is currently running inside the editor. This is useful for tool
scripts to conditionally draw editor helpers, or prevent accidentally running “game” code that would affect the scene state while in the editor:
if Engine.editor_hint:
draw_gizmos()
else:
simulate_physics()
See Running code in the editor in the documentation for more information.
Note: To detect whether the script is run from an editor build (e.g. when pressing F5
), use OS.has_feature
with the "editor"
argument instead. OS.has_feature("editor")
will evaluate to true
both when the code is running in the editor and when running the project from the editor, but it will evaluate to false
when the code is run from an exported project.
sourcepub fn is_in_physics_frame(&self) -> bool
pub fn is_in_physics_frame(&self) -> bool
Returns true
if the game is inside the fixed process and physics phase of the game loop.
sourcepub fn is_printing_error_messages(&self) -> bool
pub fn is_printing_error_messages(&self) -> bool
If false
, stops printing error and warning messages to the console and editor Output log. This can be used to hide error and warning messages during unit test suite runs. This property is equivalent to the [member ProjectSettings.application/run/disable_stderr] project setting.
Warning: If you set this to false
anywhere in the project, important error messages may be hidden even if they are emitted from other scripts. If this is set to false
in a tool
script, this will also impact the editor itself. Do not report bugs before ensuring error messages are enabled (as they are by default).
Note: This property does not impact the editor’s Errors tab when running a project from the editor.
sourcepub fn set_editor_hint(&self, enabled: bool)
pub fn set_editor_hint(&self, enabled: bool)
Sample code is GDScript unless otherwise noted.
If true
, the script is currently running inside the editor. This is useful for tool
scripts to conditionally draw editor helpers, or prevent accidentally running “game” code that would affect the scene state while in the editor:
if Engine.editor_hint:
draw_gizmos()
else:
simulate_physics()
See Running code in the editor in the documentation for more information.
Note: To detect whether the script is run from an editor build (e.g. when pressing F5

when the code is run from an exported project.
sourcepub fn set_iterations_per_second(&self, iterations_per_second: i64)
pub fn set_iterations_per_second(&self, iterations_per_second: i64)
The number of fixed iterations per second. This controls how often physics simulation and [Node._physics_process
][Node::_physics_process] methods are run. This value should generally always be set to 60
or above, as Godot doesn’t interpolate the physics step. As a result, values lower than 60
will look stuttery. This value can be increased to make input more reactive or work around collision tunneling issues, but keep in mind doing so will increase CPU usage. See also target_fps

is used consistently in physics calculations). Therefore, it is recommended not to increase Engine.iterations_per_second
above 240. Otherwise, the game will slow down when the rendering framerate goes below 30 FPS.
sourcepub fn set_physics_jitter_fix(&self, physics_jitter_fix: f64)
pub fn set_physics_jitter_fix(&self, physics_jitter_fix: f64)
Controls how much physics ticks are synchronized with real time. For 0 or less, the ticks are synchronized. Such values are recommended for network games, where clock synchronization matters. Higher values cause higher deviation of the in-game clock and real clock but smooth out framerate jitters. The default value of 0.5 should be fine for most; values above 2 could cause the game to react to dropped frames with a noticeable delay and are not recommended.

to 0
.
sourcepub fn set_print_error_messages(&self, enabled: bool)
pub fn set_print_error_messages(&self, enabled: bool)
If false
, stops printing error and warning messages to the console and editor Output log. This can be used to hide error and warning messages during unit test suite runs. This property is equivalent to the [member ProjectSettings.application/run/disable_stderr] project setting.

sourcepub fn set_target_fps(&self, target_fps: i64)
pub fn set_target_fps(&self, target_fps: i64)
The desired frames per second. If the hardware cannot keep up, this setting may not be respected. A value of 0 means no limit.
sourcepub fn set_time_scale(&self, time_scale: f64)
pub fn set_time_scale(&self, time_scale: f64)
Controls how fast or slow the in-game clock ticks versus the real life one. It defaults to 1.0. A value of 2.0 means the game moves twice as fast as real life, whilst a value of 0.5 means the game moves at half the regular speed.

sourcepub fn add_user_signal(
&self,
signal: impl Into<GodotString>,
arguments: VariantArray
)
pub fn add_user_signal(
&self,
signal: impl Into<GodotString>,
arguments: VariantArray
)
Adds a user-defined signal
. Arguments are optional, but can be added as an Array
of dictionaries, each containing name: String
and type: int
(see [enum Variant.Type]) entries.
Default Arguments
arguments
-[ ]
sourcepub unsafe fn call(
&self,
method: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
pub unsafe fn call(
&self,
method: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
Sample code is GDScript unless otherwise noted.
Calls the method
on the object and returns the result. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:
call("set", "position", Vector2(42.0, 0.0))
Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).
Safety
This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).
sourcepub unsafe fn call_deferred(
&self,
method: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
pub unsafe fn call_deferred(
&self,
method: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
Sample code is GDScript unless otherwise noted.
Calls the method
on the object during idle time. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:
call_deferred("set", "position", Vector2(42.0, 0.0))
Note: In C#, the method name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined methods where you should use the same convention as in the C# source (typically PascalCase).
Safety
This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).
sourcepub unsafe fn callv(
&self,
method: impl Into<GodotString>,
arg_array: VariantArray
) -> Variant
pub unsafe fn callv(
&self,
method: impl Into<GodotString>,
arg_array: VariantArray
) -> Variant
Sample code is GDScript unless otherwise noted.
Calls the method
on the object and returns the result. Contrarily to call
, this method does not support a variable number of arguments but expects all parameters to be via a single Array
.
callv("set", [ "position", Vector2(42.0, 0.0) ])
Safety
This function bypasses Rust’s static type checks (aliasing, thread boundaries, calls to free(), …).
sourcepub fn can_translate_messages(&self) -> bool
pub fn can_translate_messages(&self) -> bool
Returns true
if the object can translate strings. See set_message_translation
and tr
.
sourcepub fn connect(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>,
binds: VariantArray,
flags: i64
) -> GodotResult
pub fn connect(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>,
binds: VariantArray,
flags: i64
) -> GodotResult
Sample code is GDScript unless otherwise noted.
Connects a signal
to a method
on a target
object. Pass optional binds
to the call as an Array
of parameters. These parameters will be passed to the method after any parameter used in the call to emit_signal
. Use flags
to set deferred or one-shot connections. See ConnectFlags
constants.
A signal
can only be connected once to a method
. It will print an error if already connected, unless the signal was connected with CONNECT_REFERENCE_COUNTED
. To avoid this, first, use is_connected
to check for existing connections.
If the target
is destroyed in the game’s lifecycle, the connection will be lost.
Examples:
connect("pressed", self, "_on_Button_pressed") # BaseButton signal
connect("text_entered", self, "_on_LineEdit_text_entered") # LineEdit signal
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # User-defined signal
An example of the relationship between binds
passed to connect
and parameters used when calling emit_signal
:
connect("hit", self, "_on_Player_hit", [ weapon_type, damage ]) # weapon_type and damage are passed last
emit_signal("hit", "Dark lord", 5) # "Dark lord" and 5 are passed first
func _on_Player_hit(hit_by, level, weapon_type, damage):
print("Hit by %s (lvl %d) with weapon %s for %d damage" % [hit_by, level, weapon_type, damage])
Default Arguments

sourcepub fn disconnect(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>
)
pub fn disconnect(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>
)
Disconnects a signal
from a method
on the given target
.
If you try to disconnect a connection that does not exist, the method will print an error. Use is_connected
to ensure that the connection exists.
sourcepub fn emit_signal(
&self,
signal: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
pub fn emit_signal(
&self,
signal: impl Into<GodotString>,
varargs: &[Variant]
) -> Variant
Sample code is GDScript unless otherwise noted.
Emits the given signal
. The signal must exist, so it should be a built-in signal of this class or one of its parent classes, or a user-defined signal. This method supports a variable number of arguments, so parameters are passed as a comma separated list. Example:
emit_signal("hit", weapon_type, damage)
emit_signal("game_over")
sourcepub fn get(&self, property: impl Into<GodotString>) -> Variant
pub fn get(&self, property: impl Into<GodotString>) -> Variant
Returns the Variant
value of the given property
. If the property
doesn’t exist, this will return null
.
Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).
sourcepub fn get_class(&self) -> GodotString
pub fn get_class(&self) -> GodotString
sourcepub fn get_incoming_connections(&self) -> VariantArray
pub fn get_incoming_connections(&self) -> VariantArray
Returns an Array
of dictionaries with information about signals that are connected to the object.
Each Dictionary
contains three String entries:
source
is a reference to the signal emitter.signal_name
is the name of the connected signal.method_name
is the name of the method to which the signal is connected.
sourcepub fn get_indexed(&self, property: impl Into<NodePath>) -> Variant
pub fn get_indexed(&self, property: impl Into<NodePath>) -> Variant
Gets the object’s property indexed by the given NodePath
. The node path should be relative to the current object and can use the colon character (:
) to access nested properties. Examples: "position:x"
or "material:next_pass:blend_mode"
.
Note: Even though the method takes NodePath
argument, it doesn’t support actual paths to Node
s in the scene tree, only colon-separated sub-property paths. For the purpose of nodes, use Node.get_node_and_resource
instead.
sourcepub fn get_instance_id(&self) -> i64
pub fn get_instance_id(&self) -> i64
Returns the object’s unique instance ID.
This ID can be saved in EncodedObjectAsID
, and can be used to retrieve the object instance with [method @GDScript.instance_from_id].
sourcepub fn get_meta(
&self,
name: impl Into<GodotString>,
default: impl OwnedToVariant
) -> Variant
pub fn get_meta(
&self,
name: impl Into<GodotString>,
default: impl OwnedToVariant
) -> Variant
Returns the object’s metadata entry for the given name
.
Throws error if the entry does not exist, unless default
is not null
(in which case the default value will be returned).

Returns the object’s property list as an Array
of dictionaries.
Each property’s Dictionary
contain at least name: String
and type: int
(see [enum Variant.Type]) entries. Optionally, it can also include hint: int
(see [PropertyHint
][PropertyHint]), hint_string: String
, and usage: int
(see [PropertyUsageFlags
][PropertyUsageFlags]).
sourcepub fn get_script(&self) -> Option<Ref<Reference, Shared>>
pub fn get_script(&self) -> Option<Ref<Reference, Shared>>

method was called for the object.
sourcepub fn notification(&self, what: i64, reversed: bool)
pub fn notification(&self, what: i64, reversed: bool)
Send a given notification to the object, which will also trigger a call to the [_notification
][Self::_notification] method of all classes that the object inherits from.
If reversed
is true
, [_notification
][Self::_notification] is called first on the object’s own class, and then up to its successive parent classes. If reversed
is false
, [_notification
][Self::_notification] is called first on the highest ancestor (Object
itself), and then down to its successive inheriting classes.
Default Arguments
reversed
-false
sourcepub fn property_list_changed_notify(&self)
pub fn property_list_changed_notify(&self)
Notify the editor that the property list has changed, so that editor plugins can take the new values into account. Does nothing on export builds.
sourcepub fn remove_meta(&self, name: impl Into<GodotString>)
pub fn remove_meta(&self, name: impl Into<GodotString>)
Removes a given entry from the object’s metadata. See also set_meta
.
sourcepub fn set(&self, property: impl Into<GodotString>, value: impl OwnedToVariant)
pub fn set(&self, property: impl Into<GodotString>, value: impl OwnedToVariant)
Assigns a new value to the given property. If the property
does not exist or the given value’s type doesn’t match, nothing will happen.
Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).
sourcepub fn set_block_signals(&self, enable: bool)
pub fn set_block_signals(&self, enable: bool)
If set to true
, signal emission is blocked.
sourcepub fn set_deferred(
&self,
property: impl Into<GodotString>,
value: impl OwnedToVariant
)
pub fn set_deferred(
&self,
property: impl Into<GodotString>,
value: impl OwnedToVariant
)
Assigns a new value to the given property, after the current frame’s physics step. This is equivalent to calling set
via call_deferred
, i.e. call_deferred("set", property, value)
.
Note: In C#, the property name must be specified as snake_case if it is defined by a built-in Godot node. This doesn’t apply to user-defined properties where you should use the same convention as in the C# source (typically PascalCase).
sourcepub fn set_indexed(
&self,
property: impl Into<NodePath>,
value: impl OwnedToVariant
)
pub fn set_indexed(
&self,
property: impl Into<NodePath>,
value: impl OwnedToVariant
)
Sample code is GDScript unless otherwise noted.
Assigns a new value to the property identified by the NodePath
. The node path should be relative to the current object and can use the colon character (:
) to access nested properties. Example:
set_indexed("position", Vector2(42, 0))
set_indexed("position:y", -10)
print(position) # (42, -10)
sourcepub fn set_message_translation(&self, enable: bool)
pub fn set_message_translation(&self, enable: bool)
Defines whether the object can translate strings (with calls to tr
). Enabled by default.
sourcepub fn set_meta(&self, name: impl Into<GodotString>, value: impl OwnedToVariant)
pub fn set_meta(&self, name: impl Into<GodotString>, value: impl OwnedToVariant)
Adds, changes or removes a given entry in the object’s metadata. Metadata are serialized and can take any Variant
value.
To remove a given entry from the object’s metadata, use remove_meta
. Metadata is also removed if its value is set to null
. This means you can also use set_meta("name", null)
to remove metadata for "name"
.
sourcepub fn set_script(&self, script: impl AsArg<Reference>)
pub fn set_script(&self, script: impl AsArg<Reference>)
Assigns a script to the object. Each object can have a single script assigned to it, which are used to extend its functionality.
If the object already had a script, the previous script instance will be freed and its variables and state will be lost. The new script’s [_init
][Self::_init] method will be called.
sourcepub fn to_string(&self) -> GodotString
pub fn to_string(&self) -> GodotString
sourcepub fn tr(&self, message: impl Into<GodotString>) -> GodotString
pub fn tr(&self, message: impl Into<GodotString>) -> GodotString
Translates a message using translation catalogs configured in the Project Settings.
Only works if message translation is enabled (which it is by default), otherwise it returns the message
unchanged. See set_message_translation
.
