Hi there, I want to report something weird that just happened a few minutes ago. I was curious to test my Horizon worlds in a VR headset, and after a few minutes of playing, I moved back the thumbstick, and the game entered "building mode" ... I didn't know how to exit from the building mode, and I exited from the Horizon worlds application on my Quest Pro. Then I opened my world again, "The Golden Key," and after playing for a few minutes, the building mode started again because if you move down the thumbstick of the right controller, this happens. For the second time,I forced the closing of the app... And I went back to my creator profile to check the analytics of my world, and I noticed that it said that the world was updated... I literally screamed. Why? What happened? I swear on my children that I did nothing, I did not update my world, and that this was an unintended and accidental event caused by the thumbstick of the controller, which you can verify yourselves through the logs or the appropriate tools at your disposal. Please check and verify, and kindly provide me with a prompt response. Please, I don't want ot be disqaulified for that. Thank you.Taking a great picture for your world door.
For those in the contest - or any world creators, take some time to ensure that your door looks good. JB has put together a world to show you how to line up your pictures for a great world picture. Your photo should be in the 16:9 configuration. The photobooth gizmo should be centered on your photo and three meters back. If you want to add text to the photo separately it should be mirrored. The photobooth photos are not taking a photo from the center, it is over to the side. Check out the keep out lines to ensure everything is visible.

Experienced Creator Challenge: Interactive Interface Challenge Overview This challenge introduces you to the concept of building interactive Custom UIs. This is for experienced creators who are already familiarized with adding a Custom UI gizmo to a world and using TypeScript to modify the content of a CUI. You’ll learn how to: Add border formatting to a Custom UI Add interactive buttons to a Custom UI to display different images Using Bindings to make dynamic changes to a Custom UI Duration: Mar 17, 2025 - Mar 21, 2025 Estimated Time: 45mins Mentor: PigeonNo12 Rewards: Challenge Champion Badge 🏆 Challenge Trifecta Badge 🏆🏆🏆 after completing three challenges Need Help? Forum Support: I’ll be actively monitoring this thread during the Challenge duration to help you succeed Live AMA: Join my office hour Build with a Mentor: CUI on 3/20/2025 Quick Start: If you are new to building Custom UIs, check out My First Custom UI challenge here. Challenge Steps: Create a Custom UI Add a Custom UI gizmo to your world. Create a new TypeScript script. Enable the horizon/ui API in the Script settings. Attach the script to the Custom UI and display a placeholder background color. Display an image on the Custom UI Upload an image to your asset library. This will be the image displayed on the Custom UI. Modify the script to include a property variable that connects to a texture asset. Upload a texture to your asset library and assign it to the Custom UI script's property variable. Modify the script to include an Image node, using the property variable as an input. The final result should display the image on the Custom UI. Add navigation buttons Modify the Custom UI layout to include two navigation buttons: Back and Forward. Use a different background color to make them stand out. Alternatively, use an image texture (e.g., arrow icons) as button icons. Create corresponding binding variables that update when the buttons are pressed. These variables will be used to display different images on the Custom UI. Add more images and scroll through them by using the navigation buttons Upload additional images to your asset library. To keep things organized, create a folder for all images used in this challenge. Create an additional binding variable to specify the current image displayed on the Custom UI. Reference this variable in the Image node. Add more property variables and use them to connect texture assets to the script. Create a function that updates the displayed image when the pressable buttons are clicked Make it pop! Enhance the style of the Custom UI elements by modifying their configuration. Adjust borders, including their color, thickness, and roundness. Add a title and modify its font attributes, including the font family.

Experienced Creator Challenge: Make a 'Better' Interactive Gun! Challenge Overview This challenge introduces you to some of the more subtle aspects of making a good interactable object. By completing it, you will have increased experience with making your interactables feel more 'real' and tangible in Horizon Worlds. You’ll learn how to: Add haptic feedback and realistic physics Implement ammo tracking and reloading Create multiple firing modes with different behaviors If you are new to player interaction mechanics, check out my Create an Interative Gun! challenge here. Duration: Mar 10, 2025 - Mar 14, 2025 Estimated Time: Approx. 45 min. Mentor: Shards632 Rewards: Challenge Champion Badge 🏆 NEW! Challenge Trifecta Badge 🏆🏆🏆 after completing three challenges Need Help? Forum Support: I’ll be actively monitoring this thread during the Challenge duration to help you succeed Live AMA: Join my Typescript for HZW on Tuesday, March 11th at 12 PM PST Challenge Steps: 1. Create Your Foundation Create a gun per this week's New Creator Challenge. Given your experience, this should take you significantly less time than 45 minutes. Track which hand is holding the gun, and provide haptic feedback in the correct hand when fired. Provide 'recoil' to the gun by rotating it backwards around a pivot point centered at the grip when it is fired. 2. Implement Ammo System Track ammo remaining in the gun, and display this to the player somehow. Provide different audio and haptic feedback when trying to fire when empty. Provide a reloading mechanism to top up the ammo, with a sound effect and haptics, and maybe VFX. 3. Add Physics-based Projectiles Switch the launching mechanism to fire an actual Entity, like a grenade (find something in the asset library or make something quickly using primitive shapes), rather than using a Projectile Launcher. Make the 'grenade' a PhysicsEntity, position it at the gun muzzle, and use applyForce() to launch it. Perhaps give it some torque, too, to make it spin? Listen for collision events with specifically tagged objects to find out when it collides with them. You can also use a short distance raycast in the direction of motion off the front of the projectile to detect when it is about to hit something, rather than using collision events. This allows you to detect pending collisions with any geometry, regardless of tags. 4. Create Mode Switching Allow the user to switch between the two firing modes (Projectile Launcher vs Physics Entity) with a button. Track ammo separately for the two modes. Use different firing sounds and VFX, and different hitting sounds and VFX for the two types of ammo. Skills You’ll Develop: Enhance the realism of your mechanic by adding more 'real world' constraints Use haptics to enhance the VR 'feel' of your interactive Understand how to launch physics objects and detect collisions with both tagged and untagged entities What You’ll Need: Horizon Worlds Desktop Editor Visual Studio Code (configured to work with the Desktop Editor) Your Imagination!

New to Horizon Creator Challenge New Creator Challenge: Create an Interactive Gun! Challenge Overview This challenge introduces you to the basics of player interaction mechanics in Meta Horizon Worlds. You’ll learn how to: Get events when players interact with objects Fire projectiles from a launcher Detect hits and play appropriate effects Duration: Mar 10, 2025 - Mar 14, 2025 Estimated Time: Approx. 45 min. Mentor: Shards632 Rewards: Challenge Champion Badge 🏆 NEW! Challenge Trifecta Badge 🏆🏆🏆 after completing three challenges Need Help? Forum Support: I’ll be actively monitoring this thread during the Challenge duration to help you succeed Live AMA: Join my Typescript for HZW on Tuesday, March 11th at 12 PM PST Challenge Steps: 1. Create Your Gun The geometry doesn't have to be complicated! When I need a gun, I often just slap together a cylinder for the barrel and a soft cube for the handle that I get from the primitives in the build menu, and put them in a grouped entity. Or, if you want, you can grab a gun out of the asset library from the build menu. The look of the gun isn't the important thing with this challenge, it's the interactivity. But go crazy if you have mad modeling skills and import something from Blender! 2. Add Interactive Components Add a projectile launcher gizmo within the gun group, positioned at the muzzle of the gun. Add 'firing' sounds or particle effects gizmos to the group, for when the user shoots. Add grab handles to the group, and adjust the grab anchor so that the avatar holds the gun by its grip/handle. Pull a sound gizmo out of the library for an explosion sound, and a smoke poof particle effect gizmo. 3. Create the Script Create a script called "Gun" attached to the gun group. Make a property for the projectile launcher, your launching sounds and particle effects, and your exploding sounds and particle effects. Listen in preStart() to the entity for 'OnIndexTriggerDown' to find out when the player fires the gun. Listen in preStart() to the launcher gizmo for 'OnProjectileHitWorld' for when the fired projectile hits something 4. Implement the Functionality When the player fires the gun, tell the projectile launcher gizmo to launch a projectile. If you have sounds and particle effects in the gun for firing, play those now! When the projectile launcher reports the projectile hit something, use the position information in the event to move the explosion sound particle effect to that location, and then tell them both to play! 5. Share your Creation Post your published world link and a screenshot to earn your “Challenge Champion” badge! Skills You’ll Develop: Connecting entity properties to a script Connecting entity event code handlers for player and gizmo interactions Playing sounds and particle effects What You’ll Need: Horizon Worlds Desktop Editor Visual Studio Code (configured to work with the Desktop Editor) Your Imagination!
