方法说明

bool can_instantiate ( class: StringName ) const¹

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

Variant class_call_static ( class: StringName, method: StringName, ... ) vararg²

Calls a static method on a class.

bool class_exists ( class: StringName ) const¹

Returns whether the specified class is available or not.

APIType class_get_api_type ( class: StringName ) const¹

Returns the API type of class. See APIType.

PackedStringArray class_get_enum_constants ( class: StringName, enum: StringName, no_inheritance: bool = false ) const¹

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 ) const¹

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

int class_get_integer_constant ( class: StringName, name: StringName ) const¹

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 ) const¹

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 ) const¹

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 ) const¹

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 ) const¹

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 ) const¹

Returns the value of property of object or its ancestry.

Variant class_get_property_default_value ( class: StringName, property: StringName ) const¹

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 ) const¹

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 ) const¹

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 ) const¹

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 ) const¹

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

bool class_has_integer_constant ( class: StringName, name: StringName ) const¹

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 ) const¹

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 ) const¹

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

Error class_set_property ( object: Object, property: StringName, value: Variant ) const¹

Sets property value of object to value.

PackedStringArray get_class_list ( ) const¹

Returns the names of all the classes available.

PackedStringArray get_inheriters_from_class ( class: StringName ) const¹

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

StringName get_parent_class ( class: StringName ) const¹

Returns the parent class of class.

Variant instantiate ( class: StringName ) const¹

Creates an instance of class.

bool is_class_enabled ( class: StringName ) const¹

Returns whether this class is enabled or not.

bool is_class_enum_bitfield ( class: StringName, enum: StringName, no_inheritance: bool = false ) const¹

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 ) const¹

Returns whether inherits is an ancestor of class or not.
