Method Descriptions

bool can_instantiate(class: StringName) const 🔗

Returns true if objects can be instantiated from the specified class, otherwise returns false.


Variant class_call_static(class: StringName, method: StringName, ...) vararg 🔗

Calls a static method on a class.


bool class_exists(class: StringName) const 🔗

Returns whether the specified class is available or not.


APIType class_get_api_type(class: StringName) const 🔗

Returns the API type of class. See APIType.


PackedStringArray class_get_enum_constants(class: StringName, enum: StringName, no_inheritance: bool = false) const 🔗

Returns an array with all the keys in enum of class or its ancestry.


PackedStringArray class_get_enum_list(class: StringName, no_inheritance: bool = false) const 🔗

Returns an array with all the enums of class or its ancestry.


int class_get_integer_constant(class: StringName, name: StringName) const 🔗

Returns the value of the integer constant name of class or its ancestry. Always returns 0 when the constant could not be found.


StringName class_get_integer_constant_enum(class: StringName, name: StringName, no_inheritance: bool = false) const 🔗

Returns which enum the integer constant name of class or its ancestry belongs to.


PackedStringArray class_get_integer_constant_list(class: StringName, no_inheritance: bool = false) const 🔗

Returns an array with the names all the integer constants of class or its ancestry.


int class_get_method_argument_count(class: StringName, method: StringName, no_inheritance: bool = false) const 🔗

Returns the number of arguments of the method method of class or its ancestry if no_inheritance is false.


Array[Dictionary] class_get_method_list(class: StringName, no_inheritance: bool = false) const 🔗

Returns an array with all the methods of class or its ancestry if no_inheritance is false. Every element of the array is a Dictionary with the following keys: args, default_args, flags, id, name, return: (class_name, hint, hint_string, name, type, usage).

Note: In exported release builds the debug info is not available, so the returned dictionaries will contain only method names.


Variant class_get_property(object: Object, property: StringName) const 🔗

Returns the value of property of object or its ancestry.


Variant class_get_property_default_value(class: StringName, property: StringName) const 🔗

Returns the default value of property of class or its ancestor classes.


StringName class_get_property_getter(class: StringName, property: StringName) 🔗

Returns the getter method name of property of class.


Array[Dictionary] class_get_property_list(class: StringName, no_inheritance: bool = false) const 🔗

Returns an array with all the properties of class or its ancestry if no_inheritance is false.


StringName class_get_property_setter(class: StringName, property: StringName) 🔗

Returns the setter method name of property of class.


Dictionary class_get_signal(class: StringName, signal: StringName) const 🔗

Returns the signal data of class or its ancestry. The returned value is a Dictionary with the following keys: args, default_args, flags, id, name, return: (class_name, hint, hint_string, name, type, usage).


Array[Dictionary] class_get_signal_list(class: StringName, no_inheritance: bool = false) const 🔗

Returns an array with all the signals of class or its ancestry if no_inheritance is false. Every element of the array is a Dictionary as described in class_get_signal.


bool class_has_enum(class: StringName, name: StringName, no_inheritance: bool = false) const 🔗

Returns whether class or its ancestry has an enum called name or not.


bool class_has_integer_constant(class: StringName, name: StringName) const 🔗

Returns whether class or its ancestry has an integer constant called name or not.


bool class_has_method(class: StringName, method: StringName, no_inheritance: bool = false) const 🔗

Returns whether class (or its ancestry if no_inheritance is false) has a method called method or not.


bool class_has_signal(class: StringName, signal: StringName) const 🔗

Returns whether class or its ancestry has a signal called signal or not.


Error class_set_property(object: Object, property: StringName, value: Variant) const 🔗

Sets property value of object to value.


PackedStringArray get_class_list() const 🔗

Returns the names of all the classes available.


PackedStringArray get_inheriters_from_class(class: StringName) const 🔗

Returns the names of all the classes that directly or indirectly inherit from class.


StringName get_parent_class(class: StringName) const 🔗

Returns the parent class of class.


Variant instantiate(class: StringName) const 🔗

Creates an instance of class.


bool is_class_enabled(class: StringName) const 🔗

Returns whether this class is enabled or not.


bool is_class_enum_bitfield(class: StringName, enum: StringName, no_inheritance: bool = false) const 🔗

Returns whether class (or its ancestor classes if no_inheritance is false) has an enum called enum that is a bitfield.


bool is_parent_class(class: StringName, inherits: StringName) const 🔗

Returns whether inherits is an ancestor of class or not.
