My PointerEventHandler doesn't work anymore

Hello Needle,

I done the update to the 3.25.2, after that one of my script which implement IPointerClickHandler (I tried with IPointerEventHandler too) doesn’t work anymore.
I really don’t know why.

Did somebody has an idea ?

My code is like :

export class SelectableTooth 
  extends Behaviour 
  implements IPointerEventHandler 
  {
...
onPointerEnter() {...}
onPointerExit() {...}
etc

My others functions work, but the functions liked to IPointerEventHandler doesn’t work anymore

But it works for my others functions like my HotSpot Behaviour

Make sure you have an ObjectRaycaster component in the hierarchy above (or on the same object) as your EventHandler component

I maybe found, it’s maybe because the check 'ignore skinned mesh" is checked

Ah yes that could also be a reason. We’ve added this recently and will improve it further. The reason for this is that raycasting on skinned meshes is by default very expensive and previous versions have done this for every frame with an EventSystem. Subsequent versions will improve this even further and only raycast objects that have components in their hierarchy that are actually listening to those events

It’s not that…

Is your object by any chance on layer 2 ?

I don’t know what’s going on, it’s working for my hotspot but not for my tooth models

I will check but normally no

Ah my bad - it’s because skinned meshes are currently completely ignored for raycasting in the EventSystem.

Nop

With AND without the case checked ?

I might have a workaround for you, one second

17 

//@type UnityEngine.MonoBehaviour
export class SkinnedMeshRaycaster extends ObjectRaycaster {
    constructor() {
        super();
        this.ignoreSkinnedMeshes = false;  
    }
}

export class MyEventHandler extends Behaviour implements IPointerEventHandler {

    onPointerEnter(args: PointerEventData) {
        console.log("ENTER", args);
    }
}

This works

You can add a custom raycaster :slightly_smiling_face:

Hmmm

in this case we just derive from ObjectRaycaster since we want to use it’s logic (all the raycasting is already done)
