why did the events I made below not work?

why did the events I made below not work? is there something wrong? I tried to hit a collider with a weapon but it did not bring up the debug that I made

using UnityEngine;

using Opsive.Shared.Events;



public class HarvestManager : MonoBehaviour

{

    /// <summary>

    /// Initialize the default values.

    /// </summary>

    public void Awake()

    {

        EventHandler.RegisterEvent<float, Vector3, Vector3, GameObject, object, Collider>(gameObject, "OnObjectImpact", OnImpact);

    }



    /// <summary>

    /// The object has been impacted with another object.

    /// </summary>

    /// <param name="amount">The amount of damage taken.</param>

    /// <param name="position">The position of the damage.</param>

    /// <param name="forceDirection">The direction that the object took damage from.</param>

    /// <param name="attacker">The GameObject that did the damage.</param>

    /// <param name="attackerObject">The object that did the damage.</param>

    /// <param name="hitCollider">The Collider that was hit.</param>

    private void OnImpact(float amount, Vector3 position, Vector3 forceDirection, GameObject attacker, object attackerObject, Collider hitCollider)

    {

        Debug.Log(name + " impacted by " + attacker + " on collider " + hitCollider + ".");

    }



    /// <summary>

    /// The GameObject has been destroyed.

    /// </summary>

    public void OnDestroy()

    {

        EventHandler.UnregisterEvent<float, Vector3, Vector3, GameObject, object, Collider>(gameObject, "OnObjectImpact", OnImpact);

    }

}

sorry if I copy the script without using a code table because I don't know how to use it

I already know the problem where, I put it in a new object game, and it turns out the event only works if it is placed on the object being attacked. but this is very difficult for my condition because I use vegetation studio and the gameobject (vegetation) can't be added to the script, I want to make a weapon to cut down trees is there a solution for my case?

Melee weapons have an OnObjectImpact event that gets called when it collides with another object. Take a look at the "Impact Callback" section on this page: https://opsive.com/support/document...controller/items/actions/usable/melee-weapon/

ShootableWeapons and Projectiles also have a similar event, which are documented on their relevant pages.

I tried it but it didn't answer my second question, what if I use Vegetation Studio, and I want to add the events how do I do that? because the tree from VS cannot be added to a custom script

 

[Reza]

VS only provides a collider that has tags, and I mean it must detect what collider hit the weapon using a script that must be on the character, without having to add the script to the collider(tree) hit from the weapon

 

[Andrew]

The OnObjectImpact event is set up to be sent to the target object.

I'm unfamiliar with Vegetation Studio. I'm guessing it spawns a bunch of prefabs during run-time? If that's the case, you may be able to add the impact detection script to the prefab/s that it spawns, or even add them during run-time (you'd have to refer to the docs/support for VS for help with this). Another approach would be to have a manager that adds the impact detection script to the relevant objects during run-time based on tags/layers.

Impact detection can be used on any prefab with a collider; there's no other setup or configuration required.

okay I forgot about that now I can take the object from the tag using the script and then add the events component
