Issue with CustomEvents

[gilded moat]

Hi I'm following the documentation of Declare a custom event type : https://engine.needle.tools/docs/scripting-examples.html#create-and-invoke-a-unityevent

1 - I have added this C# script to the Needle/Components.codegen file :

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;

[System.Serializable]
public class MyCustomUnityEvent : MonoBehaviour
{
}

2- Then I copy-pasted both classes from the documentation

    // The next line is not just a comment, it defines 
    // a specific type for the component generator to use.

    //@type MyCustomUnityEvent
    @serializable(EventList)
    myEvent!: EventList;

    // just for testing - could be when a button is clicked, etc.
    start() {
        this.myEvent.invoke("Hello");
    }
}

export class CustomEventReceiver extends Behaviour {

    logStringAndObject(str: string) {
        console.log("From Event: ", str);
    }
}```

3- But when I add both scripts to an GameObject , the field of `myEvent` from `CustomEventCaller ` looks like this and I cannot add the the reference of `CustomEventReceiver ` :

If I delete this line from CustomEventCaller : //@type MyCustomUnityEvent, then it looks like this :

But when I Invoke the method, nothing happens

Do you know what could be happening ?

If you do not have any methods/listeners added to your event list / unity event then nothing will happen if you call invoke

Click the plus button in the MyEvent list in unity and add a method to be called when you invoke your Event. What you have been building here is a flexible way to connect events in the unity editor 🙂 you just need to make the connections now and it will work

That´s the problem, if I add a method to the MyEventList nothing happens in this case. I follow each step in the documentation but it doesn´t work. Could you give a brief explanation of each step to call a custom event ? Maybe there is something I am losing.

[lean ember]

Can you show an example where you have added a method to the event?

[gilded moat]

Srry for no answer but I made another example and it works almost fine. This is my example :
I have a Sphere with two scripts :
The first one :

    // The next line is not just a comment, it defines 
    // a specific type for the component generator to use.

    
    @serializable(EventList)
    myEvent!: EventList;


    update(): void {
        if(this.context.input.getKeyDown()=='a'){
            this.myEvent.invoke("Hello");
        }
    }
}```
The second one : 

export class CustomEventReceiver extends Behaviour {
logStringAndObject(str: string) {
console.log("From Event: "+str);
}
}

This is how the sphere looks in Unity :

This is the console's log :

So it seems that the event actually is beeing invoking but not with the argument of "Hello" which I'm passing in CustomEventCaller.

Otherwise if I write directly in Unity the argument for the method logStringAndObject, like this :

This is my log.

But I want the argument to be passed from the script CustomEventCaller, Do you know what could be wrong ? Thanks 🙂

When you save this script again the component generator will create UnityEvent without the argument - which seems to be what you actually want. If you have a string argument serialized in Unity that's what will be used to invoke the event
