Creating a Throwable Interaction in Meta Horizon Worlds Desktop Editor

When to use:

When you want to design an interaction for mobile players that requires throwing a held item.

It creates a fun interaction that is easy to implement and doesn’t require scripting.

From the Desktop Editor, go to the Build menu and select Empty Object
This will add a container where we can place all the items that you want to include in the throwable, like visual effects and meshes
Add a shape to the world, from Build > Shapes. We will be using a sphere for this example, by clicking on the shape and dragging it next to the empty
Using the hierarchy, place the shape inside the empty object
With the shape still selected, go to the properties (right panel), and change its positon to x: 0, y: 0, z: 0
Select the Empty object from the hierarchy
Go the the properties (right panel) and change the Motion to Interactive
Change the Interaction to Physics and Grabbable
Adjust the Scale to x:0.4, y:0.4, z:0.4
Press the Play button to enter preview mode
Approach the sphere, and press E to grab it
While grabbing the sphere, press and hold the release button for 3 seconds to charge the throw
Release the button and the avatar will throw the object
Press ESC twice on your keyboard to exit preview mode
Go to Build > Gizmos
Search for Trail
Drag it into the scene, next to the throwable
With the gizmo select, go to the properties and change its scale to x: 0.2, y: 0.2, z: 0.2
From the hierarchy, drag the gizmo inside the empty object
With the trail effect still selected, go to the properties, and change its position to x:0, y: 0, z: 0
Enter preview mode again, and observe the trail effect that follows the object when in motion
