jeremy

Hi all I tried to use signal in my code but i get a error when my character enters the detection zone and the code try to execute the methode

i make the signal connection in the code.

can any body tell me whats going wrong :/

error: E 0:00:08.376   emit_signal: Error calling method from signal 'body_entered': 'KinematicBody2D(flyEnemy.cs)::onHurtboxBodyEntered': Method not found..
  <C++ Source>  core/object.cpp:1228 @ emit_signal()

---

using Godot;
using System;

public class flyEnemy : KinematicBody2D
{
    [Export]
    float GRAVITY = 500;
    [Export]
    float speed =200;

    private Vector2 motion = Vector2.Zero;
   
    public override void _Ready()
    {
        GetNode("hurtbox").Connect("body_entered", this, nameof(onHurtboxBodyEntered));
    }

    public override void _PhysicsProcess(float delta){
        motion.y += GRAVITY * delta;
        motion = MoveAndSlide(motion, new Vector2(0, -1));
    }

    private void onHurtboxBodyEntered() => QueueFree();

}

I have not used signals in C# myself, but based on my C# experience, I think the issue is that the onHurtboxBodyEntered function is private and therefore cannot be called by the signal. I'd try changing it to a public function and see if that fixes the issue.

I already tried to put it as public but still the same result

its strange have that he tells me he can't vind the methode when the methode is right there in the same file

I found the answer godot don't make the methode automatically C# (VisualCode)

so i had to write it my self ( that is the private void onHurtboxBodyEntered()) but for some reason the methode needs a parameter Object body

so the correct methode is :

private void onHurtboxBodyEntered(Object body){}
