Features

Roslyn Syntax Tree Visualizer

• Exports the syntax tree of a class to Godot nodes for inspection

Godot Library

• Convert GDScript Enum Types Node.ProcessModeEnum to Node.ProcessMode
• Convert GDScript Enum Values Node.ProcessModeEnum.Disabled to Node.PROCESS_MODE_DISABLED
• Convert Godot.GD functions to global functions GD.print to print

GD Script Injection

• Add GDScript from comment with GDGlue.CommentToGD
• Add GDScript by string with GDGlue.InserGDScript

C# Files

• Create own files for each class/struct
• Create wrapper class for single file enum enum RJ_TriggerMode to class_name RJ_TriggerModeEnums
• Create prefixed names for Rokojori Object Types
• Handles partial classes split into multiple files

C# List/Array

• List/Array => Array: Length/Count to size(), Add to append ,Remove to erase etc

C# Dictionary

• Dictionary<K,V> => Dictionary[K,V]

C# HashSet

• HashSet => Dictionary[K,true]

C# String

• string: Length to length()
• Automatic string conversion of number/string add binary expressions n+s to str(n)+s

C# Delegates/GDScript Callable

• add call invocation callable(x) to callable.call( x )
• rewrite to not-nullable type with
• declaration null-initializers from null to Callable()
• variable null-initializers from null to Callable()
• null-comparisons from c == null to c == null || c.is_null()

Comments

• Converting class comments
• Converting member comments

Properties

• Getters/setters creation

Export Annotations

• Basic Export
• ExportToolButton
• ExportGroup
• ExportCategory

Nullables

• Handling nullable types of C# (String, Dictionary, Acrray, Callable) on member/local declarations/parameters
• Adding and assigning null flag on assignment, passing default instead null
• Reading null flag instead value for null comparisons

GD Functions

• Ommiting return type value description in GDScript with Rokojori.Null as return type

Math

• float.MaxValue converted to value
• float.IsInfinity to is_inf
• float.IsNaN to is_nan
• Converting modulo a % b to func fmod( a, b )
• Convert Godot.Mathf functions to global functions Mathf.max to max
• Convert Godot.Mathf XXXtoInt to XXX Mathf.RoundToInt to round

Generics

• Prepend/append type as parameter for per class, for all methods
• Prepend/append type as parameter individually for a method

Statements

• For loops with increments

Expressions

• Remove as expressions of interfaces instance as InterfaceType

C# Method Overloading

• Throwing errors on method overloading
