A drop-in UdonSharp collectible system for VRChat worlds. Synced progress, animated UI, custom sounds, and unlock anything — treasures, secret doors, or entire hidden areas.

Turn exploration into a shared quest.

Collectible System is a ready-to-use UdonSharp package for VRChat world creators who want polished collect-a-thon gameplay without building sync logic from scratch. Players pick up items across your map; progress is shared for everyone in the instance. When the final item is collected, your reward appears — a trophy, a secret door, a teleport, or an entire hidden dimension.

Perfect for:

• Treasure hunts & scavenger quests
• Secret areas and hidden passages
• Quest-style world progression
• Event worlds and puzzle experiences
• Any world that needs “collect X items to unlock Y”

What you get

• CollectibleUnlockManager — global sync, UI, sounds, and reward unlock
• CollectibleItem — per-pickup script (works with VRC Pickup)
• Ready-made prefabs — CollectibleSystem, example collectibles, Reward, CanvasCount UI
• Progress UI — global counter (0/5 → 5/5) + smooth animated fill bar
• Per-spot labels — optional world-space text at each collect location
• Audio — collect sound + separate victory sound on the last pickup
• Full documentation — ReadMe.txt + commercial-friendly License.txt

Key features

✅ Multiplayer synced — all players see the same progress, disappearing items, and unlocked reward
✅ Flexible item count — use 3, 5, 7, or more collectibles (not hardcoded to 5)
✅ Any reward you want — unlock any GameObject: chest, door, portal, room, or parent group
✅ Swap any collectible — coins, keys, crystals, documents — anything with VRC Pickup
✅ Smooth progress bar — animated fill on each pickup
✅ Victory moment — special sound when the last item is collected
✅ Clean English codebase — easy to read, modify, and extend
✅ Commercial license included — use in free and paid VRChat worlds

How it works

2. Assign your collectibles and reward in the Inspector
3. Compile with UdonSharp

When a player picks up an item, it hides for everyone, the global counter updates, the progress bar animates, and local labels can show collection order. Complete the set — reward unlocked.
