A class that stores an expression you can execute.
class ExpressionAn expression can be made of any arithmetic operation, built-in math function call, method call of a passed instance, or built-in type construction call.
An example expression text using the built-in math functions could be sqrt(pow(3, 2) + pow(4, 2)).
In the following example we use a LineEdit node to write our expression and show the result.
import SwiftGodotFramework to write Godot Game Extensions using the Swift Programming Language.
class LineEditAn input field for single-line text.
class RefCountedBase class for reference-counted objects.
protocol CustomStringConvertibleA type with a customized textual representation.
protocol EquatableA type that can be compared for value equality.
protocol Hashable : EquatableA type that can be hashed into a Hasher to produce an integer hash value.
protocol Identifiable<ID>A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentable : VariantStorableTypes that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.
protocol VariantStorableTypes that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.
override class var godotClassName: StringName { get }final func execute(inputs: GArray = GArray (), baseInstance: Object? = nil, showError: Bool = true, constCallsOnly: Bool = false) -> Variant Executes the expression that was previously parsed by parse(expression:inputNames:) and returns the result. Before you use the returned object, you should check if the method failed by calling hasExecuteFailed.
final func getErrorText() -> String Returns the error text if parse(expression:inputNames:) or execute(inputs:baseInstance:showError:constCallsOnly:) has failed.
final func hasExecuteFailed() -> Bool Returns true if execute(inputs:baseInstance:showError:constCallsOnly:) has failed.
final func parse(expression: String, inputNames: PackedStringArray = PackedStringArray()) -> GodotError Parses the expression and returns an GodotError code.
