Simple Object Spawner

Enable a preset object at a spawn point when interacted with.

Category: Utility Tools

UdonSharp Script

using UdonSharp;
using UnityEngine;
using VRC.SDKBase;
using VRC.Udon;

public class SimpleObjectSpawner : UdonSharpBehaviour
{
    public GameObject objectToSpawn;
    public Transform spawnPoint;

    public override void Interact()
    {
        VRCPlayerApi localPlayer = Networking.LocalPlayer;
        if (localPlayer == null || objectToSpawn == null || spawnPoint == null) return;

        Networking.SetOwner(localPlayer, objectToSpawn);
        objectToSpawn.transform.SetPositionAndRotation(spawnPoint.position, spawnPoint.rotation);
        objectToSpawn.SetActive(true);
    }
}

Setup

  1. Place an inactive object in scene (objectToSpawn).
  2. Create empty transform as spawnPoint.
  3. Add this script to a button with VRC_Interactable.
  4. Assign references.

Notes

  • This pattern is for pre-placed objects, not runtime prefab instantiation.
  • Add a paired reset script for repeated interactions.

Extra Tips and Troubleshooting

Tips and Tricks

  • Use one spawn location per object type to reduce confusion.
  • Pair spawner with a reset/cleanup button for repeat sessions.

Troubleshooting

  • If object appears in wrong place, verify spawn transform rotation and parent hierarchy.

Prefab Setup Notes

Import the prefab or script into a throwaway test scene before adding it to a live world. Confirm inspector references, ownership behavior, sync, triggers, UI hooks, and audio or object links before moving it into the production scene.

Testing Checklist

  • Test once as a local player and again with a second client or late joiner if the behavior can affect more than one player.
  • Confirm ownership, sync, trigger zones, UI references, and audio or object references are assigned intentionally.
  • Check desktop and VR interaction distance so players can actually use the feature in context.
  • Keep a backup of the scene before changing prefabs, UdonBehaviours, or serialized references.
