Easily debug in-game by adding the [Visualize] attribute to any of the supported members. This feature allows you to visualize and interact with various types of data directly within the game environment.

Numericals	✅	int, float, double	All numerical types are supported
Enums	✅	Direction, Colors	All enum types are supported
Booleans	✅	bool
Strings	✅	string
Color	✅	Color
Vectors	✅	Vector2, Vector2I, Vector3, Vector3I, Vector4, Vector4I
Quaternion	✅	Quaternion
NodePath	✅	NodePath
StringName	✅	StringName
Methods	✅		Method parameters support all listed types here
Static Members	✅		This includes static methods, fields, and properties
Arrays	✅	int[], string[], Vector2[]	Arrays support all listed types here
Lists	✅	List<string[]>, List<Vector2>	Lists support all listed types here
Dictionaries	✅	Dictionary<List<Color[]>, Vector2>	Dictionaries support all listed types here

Godot Dictionary	❌	Godot.Collections.Dictionary	Tracking in https://github.com/ValksGodotTools/Template/issues/58

Important

There are some annoyances when trying to visualize members from inherited classes. I will try to solve this later.

Example Usage

// You will be able to view realtime changes to curState, Position and Rotation
[Visualize(nameof(currentState), nameof(Position), nameof(Rotation))]
public partial class Player : CharacterBody2D
{
    // You will be able to edit this in-game
    [Visualize] private static int _totalPlayers;

    // Visualize will check every 1000ms if currentState gets defined
    State currentState;

    public override void _Ready()
    {
        currentState = new State("Idle");
    }

    // You will be able to execute this method in-game
    [Visualize]
    public void Attack(int damage)
    {
        Visualize.Log(damage);
    }
}

Console Commands

Important

Static functions are not yet supported. Should be easy to implement, I have not got around to doing it yet.

Adding the ConsoleCommand attribute to any function will register it as a new console command.

Note

The in-game console can be brought up with F12

[ConsoleCommand("help")]
void Help()
{
    IEnumerable<string> cmds = Game.Console.Commands.Select(x => x.Name);

    Game.Log(cmds.Print());
}

Console commands can have aliases, this command has an alias named "exit"

[ConsoleCommand("quit", "exit")]
void Quit()
{
    GetTree().Root.GetNode<Global>("/root/Global").Quit();
}

Most method parameters are supported, allowing for more dynamic interactions

[ConsoleCommand("debug")]
void Debug(int x, string y)
{
    Game.Log($"Debug {x}, {y}");
}
