C# What am I missing?

UnknownUser

I am trying to do HeartBeast Action RPG tutorial using C# and I'm stuck right here.

        var GrassEffect = (PackedScene)GD.Load("res://Res/Effects/GrassEffect.tscn");
        var grassEffect = GrassEffect.Instance();
        var world = GetTree().CurrentScene;
        world.AddChild(grassEffect);
        grassEffect.GlobalPosition = GlobalPosition;

Last line gives me an error: 'Node' does not contain a definition for 'GlobalPosition' and no accessible extension method 'GlobalPosition' accepting a first argument of type 'Node' could be found (are you missing a using directive or an assembly reference?)

Is this 2D or 3D? Because GlobalPosition is only for 2D and it looks like you're using a Node (which is for 3D). I believe you just want to change that object to Node2D if you're using 2D.

I managed to make it work. I was trying to find a solution in the last line but turns out I had to instantiate Node2D in second line.

        var GrassEffect = (PackedScene)GD.Load("res://Res/Effects/GrassEffect.tscn");
        var grassEffect = (Node2D)GrassEffect.Instance();
        var world = GetTree().CurrentScene;
        world.AddChild(grassEffect);
        grassEffect.GlobalPosition = GlobalPosition;

This is all new to me and I don't fully understand how it works. Anyway thanks for pointing that out.

Actually Node isn't 3D, I was mistaken (that's Spatial). But Node is a parent class of Node2D. I wonder if you look in the GrassEffect scene, is it a Node or Node2D? Because the cast you did might not be needed if you change the type for GrassEffect (you can right click the node and choose change type and then also change the first import line in the script).

Spatial inherits from Node which in turn inherits from Object. Node2D inherits from CanvasItem which inherits from Node, which as mentioned inherits from Object.
