24.00 Release

What's New

Maximum Publish Downlaod

With the new updates to Maximum Publish Download Size the maximum download size for publishing has been increased from 300MB to 400MB.

In the future, we intend to have per platform limitations that will vary.

Asset Validation

With release 24.00, asset validation was introduced to verify that content is allowed in a UEFN project.

UEFN

Below is a list of fixed UI elements and bugs with Audio and Device features and functionality.

Audio

Fixes:

• Audio Player now uses Play() and Stop() instead of Activate() and Deactivate()
• Audio Player now has an option to call Play(Agent) or Stop(Agent) if you want to direct audio at a specific user.
• Radio now uses Play() and Stop() instead of PlayRadio() and Stop Radio()

Devices

Fixes:

• For the 24.01 release, Spray Decals will not validate. This will prevent you from playing these projects. Remove Spray Decals until this issue addressed. It will be addressed at a later date.
• If you add the Day Sequence Device, delete it, then undo, the editor may be in a conflicted state where lighting updates do not work. In this case, close the editor, then reopen it.
• If you are using Perforce, using the hide function then saving will result in every file (one file per actor) being checked out and save for the level failing. This will be addressed in a future release.
• Under World Settings, if you remove the Day Night Cycle from the World Time of Day Manager, you may not be able to save your level. If using Perforce, it also may result in the check-out of every file in the one-file-per-actor system. This will be addressed in a future release.
• After using the event binding in Creative Edit mode, if those devices are copy and pasted in the editor, they will lose their event binding references. This only affects events bound in the Fortnite client, and doesn’t affect devices bound in the UEFN editor. This will be fixed in a future release.
• Vaulting — Enabling Vaulting on the island settings results in vaulting not functioning in play.
• Engaging tactical sprint while in the pre-game phase of an island running from a test island code results in a broken sprinting animation state.
• If the user disables the sprinting and sliding, players will see buggy sprint animation when trying to sprint and slide while in edit mode.
• Random Number Generator Device no longer takes an optional Agent argument. Instead users can either choose to call a function with a mandatory Agent argument, or one with no arguments at all.
• Switch Device no longer takes an optional Agent argument. Instead users can either choose to call a function with a mandatory Agent argument, or one with no arguments at all.
• Timer Device no longer takes an optional Agent argument. Instead users can either choose to call a function with a mandatory Agent argument, or one with no arguments at all.
• Bear Spawner Device has been renamed to vehicle_spawner_pickup_truck_device.
• Mudflap Spawner Device has been renamed to vehicle_spawner_big_rig_device.
• Prevalent Spawner Device has been renamed to vehicle_spawner_sedan_device.
• Whiplash Spawner Device has been renamed to vehicle_spawner_sports_car_device.

Verse

API

New:

• Support for Verse code finding props and user devices by tag. This includes renaming:

  • GetDevicesWithTag to GetCreativeObjectsWithTag
  • GetDevicesWithTags to GetCreativeObjectsWithTags

• The GetCreativeObjectsWithTag and GetCreativeObjectsWithTags functions also return a creative_object_interface which can then be cast to each of these:

        # Some test code for finding all of these that have an all_tag on them and then casting to the appropriate type
        AllCreativeObjects:[]creative_object_interface := GetCreativeObjectsWithTag(all_tag{})

        for (PropItem:AllCreativeObjects):
            if (TheProp := creative_prop[PropItem]):
                Logger.Print("Prop found with all_tag at position: {TheProp.GetTransform().Translation}")

        for (DeviceItem:AllCreativeObjects):
            if (TheDevice := creative_device_base[DeviceItem]):
                Logger.Print("Creative device found with all_tag at position: {TheDevice.GetTransform().Translation}")
        
        for (UserDeviceItem:AllCreativeObjects):
            if (TheDevice := creative_device[UserDeviceItem]):
                Logger.Print("User device found with all_tag at position: {TheDevice.GetTransform().Translation}")
Copy full snippet

# Some test code for finding all of these that have an all_tag on them and then casting to the appropriate type AllCreativeObjects:[]creative_object_interface := GetCreativeObjectsWithTag(all_tag{}) for (PropItem:AllCreativeObjects): if (TheProp := creative_prop[PropItem]): Logger.Print("Prop found with all_tag at position: {TheProp.GetTransform().Translation}") for (DeviceItem:AllCreativeObjects): if (TheDevice := creative_device_base[DeviceItem]): Logger.Print("Creative device found with all_tag at position: {TheDevice.GetTransform().Translation}") for (UserDeviceItem:AllCreativeObjects): if (TheDevice := creative_device[UserDeviceItem]): Logger.Print("User device found with all_tag at position: {TheDevice.GetTransform().Translation}")

• Added fort_character.IsActive to indicate the character is active. If IsActive returns false, most character actions will silently fail.
• Added vector3.IsAlmostZero(tolerance) and IsAlmostEqual(vector3, vector3, tolerance) to more easily allow testing for these states.
• Added support for NamedColors.Tan.

Changed:

These are included for if you are upgrading a project that is upgrading from a release prior to 24.00.

• Renamed ToStringSeparated to Join.
• The EpicGames.com module has been renamed to UnrealEngine.com. Replace using { /EpicGames.com/ } with using { /UnrealEngine.com/ }.

• Some events were changed to have an optional agent result. You should now check to see if there was an agent or not.

  • creature_placer_device.EliminatedEvent()
  • wildlife_spawner_device.DamagedEvent()
  • supply_drop_spawner_device.BalloonPoppedEvent()

For example, what was:

AwaitTrigger(Trigger:trigger_device, GroupEvent:event(agent))<suspends>:void =
    GroupEvent.Signal(Trigger.TriggeredEvent.Await())
Copy full snippet

AwaitTrigger(Trigger:trigger_device, GroupEvent:event(agent))<suspends>:void = GroupEvent.Signal(Trigger.TriggeredEvent.Await())

is now:

AwaitTrigger(Trigger:trigger_device, GroupEvent:event(agent))<suspends>:void =
    loop:
        MaybeAgent := Trigger.TriggeredEvent.Await()
        if (TriggerAgent := MaybeAgent?):
            GroupEvent.Signal(TriggerAgent)
            break  # exit loop
        # No agent so loop back for another trigger
Copy full snippet

AwaitTrigger(Trigger:trigger_device, GroupEvent:event(agent))<suspends>:void = loop: MaybeAgent := Trigger.TriggeredEvent.Await() if (TriggerAgent := MaybeAgent?): GroupEvent.Signal(TriggerAgent) break # exit loop # No agent so loop back for another trigger

The Verse team has been performing final reviews for the 24.01 release. This review resulted in changes to standardize the Verse API and minimize inconsistencies.

Removed:

• Removed editable_text_base, editable_text, and editable_text_box widgets from the Verse UI API.
