Struct gdnative_bindings::Object
source · pub struct Object { /* private fields */ }Expand description
The base class of all classes in the Godot hierarchy.
This class has related types in the object module.
Official documentation
See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.
Memory management
Non-reference-counted objects, such as the ones of this type, are usually owned by the engine.
Object is a reference-only type. Persistent references can
only exist in the unsafe Ref<Object> form.
In the cases where Rust code owns an object of this type, for example if the object was just
created on the Rust side and not passed to the engine yet, ownership should be either given
to the engine or the object must be manually destroyed using Ref::free, or Ref::queue_free
if it is a Node.
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.

source§impl Object
impl Object
sourcepub fn new() -> Ref<Self, Unique>
pub fn new() -> Ref<Self, Unique>
Creates a new instance of this object.
Because this type is not reference counted, the lifetime of the returned object is not automatically managed.
Immediately after creation, the object is owned by the caller, and can be
passed to the engine (in which case the engine will be responsible for
destroying the object) or destroyed manually using Ref::free, or preferably
Ref::queue_free if it is a Node.
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
binds-[ ]flags-0
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:
sourceis a reference to the signal emitter.signal_nameis the name of the connected signal.method_nameis 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 Nodes 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).
Default Arguments
default-null
sourcepub fn get_meta_list(&self) -> PoolArray<GodotString>
pub fn get_meta_list(&self) -> PoolArray<GodotString>
Returns the object’s metadata as a PoolStringArray.
sourcepub fn get_method_list(&self) -> VariantArray
pub fn get_method_list(&self) -> VariantArray
Returns the object’s methods and their signatures as an Array.
sourcepub fn get_property_list(&self) -> VariantArray
pub fn get_property_list(&self) -> VariantArray
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>>
Returns the object’s Script instance, or null if none is assigned.
sourcepub fn get_signal_connection_list(
&self,
signal: impl Into<GodotString>
) -> VariantArray

&self,
signal: impl Into<GodotString>
) -> VariantArray
Returns an Array of connections for the given signal.
sourcepub fn get_signal_list(&self) -> VariantArray
pub fn get_signal_list(&self) -> VariantArray
Returns the list of signals as an Array of dictionaries.
sourcepub fn has_meta(&self, name: impl Into<GodotString>) -> bool
pub fn has_meta(&self, name: impl Into<GodotString>) -> bool
Returns true if a metadata entry is found with the given name.
sourcepub fn has_method(&self, method: impl Into<GodotString>) -> bool
pub fn has_method(&self, method: impl Into<GodotString>) -> bool
Returns true if the object contains the given method.
sourcepub fn has_signal(&self, signal: impl Into<GodotString>) -> bool
pub fn has_signal(&self, signal: impl Into<GodotString>) -> bool
Returns true if the given signal exists.
sourcepub fn has_user_signal(&self, signal: impl Into<GodotString>) -> bool
pub fn has_user_signal(&self, signal: impl Into<GodotString>) -> bool
Returns true if the given user-defined signal exists. Only signals added using add_user_signal are taken into account.
sourcepub fn is_blocking_signals(&self) -> bool
pub fn is_blocking_signals(&self) -> bool
Returns true if signal emission blocking is enabled.
sourcepub fn is_class(&self, class: impl Into<GodotString>) -> bool
pub fn is_class(&self, class: impl Into<GodotString>) -> bool
sourcepub fn is_connected(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>
) -> bool
pub fn is_connected(
&self,
signal: impl Into<GodotString>,
target: impl AsArg<Object>,
method: impl Into<GodotString>
) -> bool
Returns true if a connection exists for a given signal, target, and method.
sourcepub fn is_queued_for_deletion(&self) -> bool
pub fn is_queued_for_deletion(&self) -> bool
Returns true if the Node.queue_free 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.
