- Open your own experience in Roblox Studio and show the Explorer and Output panels.
- Published test experience with API access. This learning example needs retries, autosave and session locking before production.
- Insert a Script at
ServerScriptService. - Paste the code, press Play and test the behavior. Read Output if anything fails.
Line by line
1. Loads a coin value when the player joins.
2. Avoids saving a default value if loading fails.
3. Attempts to save on leaving and server shutdown.
Common mistakes
!
Check the object names and script location.
Names are case sensitive. A LocalScript needs a client execution context, while server data and permissions belong in a Script. Test with multiple players before publishing.
