Additional Notes

This was working fine yesterday (September 25) and today (September 26) it’s not.

Same. I logged this issue yesterday as well:

VFX Spawner Devices no longer work in-editor and live games.

I’ve also tested that setting VFX Spawner Devices “Enabled on Phase” to “Always” does not help. I’m also listening to EffectEnabledEvent() with a print log message, but it never fires when .Enable() is called.

@Kawelo I found a workaround:

VFX Spawner Devices no longer work in-editor and live games.

I found a workaround that enables VFX Spawner Devices: Use TeleportTo to move your VFX spawner some nominal distance. Then, call Enable(). Your spawner should work as normal. You only need to do the first step once. You can Enable() and Disable() as much as you want from there. Hope this helps others!

Thank you, I will try this today and give an update if this is a fix!

[Kawelo]

How exactly did you do this? sorry I’m kind of new to verse.

[agent_disco]

In the verse file of your device, add a reference to the VFX spawner:
@editable VFXDevice : vfx_spawner_device = vfx_spawner_device{}

In the editor, be sure to add the VFX spawner to this property.

Back in the verse file, do the following in OnBegin():

Pos := VFXDevice.GetTransform().Translation
Rot := VFXDevice.GetTransform().Rotation
if:
   VFXDevice.TeleportTo[Pos, Rot]

This will simply teleport the VFX spawner to the same position, which somehow enables it properly so that your effect works.

Works for me too, here’s what I added to the code.

if (Vfx.TeleportTo[Vfx.GetTransform().Translation, Vfx.GetTransform().Rotation]):
      block:

[Kawelo]

Thank you! It works good for some of the effects, but I also have effects that should activate at a position offset a player. And I’m sure you need a lot more coding for that, but thanks again for letting me know the work around.

[robc]

An offset position may not be too much harder.

Here’s an example.

        # The 'translation' is the position/location.
        CurTranslation := Vfx.GetTransform().Translation

        # This example should put it 100 units (cm) further on the X axis.
        NewTranslation := vector3{X := CurTranslation.X + 100.0, Y := CurTranslation.Y, Z := CurTranslation.Z}

         if (Vfx.TeleportTo[NewTranslation, Vfx.GetTransform().Rotation]):
            block:
