Question

How do I call a C# method from gdscript?

My gdscript code looks something like this:

func _ready():
var thingy = $CsharpUnderlingNode.yummy(2)

C# code:

static string yummy(number){
return number + 15;

}

But I’m getting this error:
Invalid call. nonexistent function ‘yummy’ in base ‘Node2D yummything.cs’.

This is not my actual code but it works the same functionally.

I have no idea how to fix it.

If you can help please let me know.

[EvilGenius]

your gdscript needs a class_name yourClass to be able to access it globally

[derpysphere]

What does that mean exactly?

[EvilGenius]

at the top of your script add

class_name yourClass where yourClass is the name of your script

Could you provide an example? I don’t quite understand.
