Bridge between Godot and the Mono runtime (Mono-enabled builds only). This class is a bridge between Godot and the Mono runtime. It exposes several low-level operations and is only available in Mono-enabled Godot builds. See also [CSharpScript]. Attaches the current thread to the Mono runtime. Detaches the current thread from the Mono runtime. Returns the current MonoDomain ID. [b]Note:[/b] The Mono runtime must be initialized for this method to work (use [method is_runtime_initialized] to check). If the Mono runtime isn't initialized at the time this method is called, the engine will crash. Returns the scripts MonoDomain's ID. This will be the same MonoDomain ID as [method get_domain_id], unless the scripts domain isn't loaded. [b]Note:[/b] The Mono runtime must be initialized for this method to work (use [method is_runtime_initialized] to check). If the Mono runtime isn't initialized at the time this method is called, the engine will crash. Returns [code]true[/code] if the domain is being finalized, [code]false[/code] otherwise. Returns [code]true[/code] if the Mono runtime is initialized, [code]false[/code] otherwise. Returns [code]true[/code] if the Mono runtime is shutting down, [code]false[/code] otherwise. Returns [code]true[/code] if the scripts domain is loaded, [code]false[/code] otherwise.
