Optional for Godot (GDScript)

A Java-style Optional<T> implementation for Godot Engine (GDScript). Helps you safely wrap nullable values and avoid unsafe null checks.

Features

• Optional.of(value) – requires a non-null value
• Optional.of_nullable(value) – wraps value, allows null
• Optional.empty() – explicitly empty optional
• unwrap() – get the value or assert
• unwrap_or(default) – get value or fallback
• map(func) – transform value if present
• flat_map(func) – transform with function returning Optional

Example

var maybe_number = Optional.of_nullable(42)
maybe_number.if_present(func(v): print("Value is: ", v))

var result = maybe_number.map(func(v): return v * 2).unwrap_or(0)
print(result) # -> 84

Installation

1. Copy the addons/optional/ folder into your project.
