  • Edit an Asset
    • Why: Allows you to correct mistakes or add features to an asset.
    • Uses: Update an asset once and propagate the change to all the worlds that use it.
  • Spawn an Asset
    • Why: Allows you to control the amount of resources being used in your world by determining when, where, and how an asset arrives in your world.
    • Uses: Spawn creatures only when a player is near a specific area, create a grabbable that replenishes each time a player grabs one, and much more!

    I see how I can access the spawned Entity using this.world.spawnAsset since it returns a Promise<Entity[]>. But what if I use the hz.SpawnController?  It only seems to return Promise<void> for its methods. I would like to be able to get the spawned Entity and add attributes (such as physics, tags, scripts?, etc.).

      According to the Creator Manual, after the promise is received you have to use controller.rootEntities to receive the entity array. Hope that helps.

    Added my baseball as an asset from the batting cage tutorial. While spawning, I learned that you can't do that from a local script. To modify the asset, I removed the ball script that was originally attached (it did the pseudo-spawn thing like in the tutorial. somewhere along the way, I lost the ability to actually hit the ball (during the tutorial, I got a nice "crack of the bat" sound effect and had to put colliders up to stop the ball from falling off the edge of the world.  The spawn works like this: when you grab the bat, the ball will spawn from an offset from the player's position (not yet rotation).  When you let go of the bat, the ball is deleted.  I will keep working to get back the capability to actually hit the ball and will eventually add some graphics to document hits and misses.

    I am glad this challenge was put out: I can see spawning items in many situations.

      Great job on this. You are correct, local scripts cannot access PPVs or handle spawning/despawning. You may have to explore transferring ownership of the ball and bat to the player if you haven't already.

      It would suggest it doesn't have access to the definition file, which is created on your computer by default when you join a world and create a new script. Is this SimpleSpawning file being run from a world folder created by the desktop editor, or just in a separate folder you created?
