Save and share worlds

EaglercraftX 1.8 saves singleplayer worlds in the browser. The official play FAQ documents EPK import/export for transfers between devices and ZIP import/export for vanilla Minecraft 1.8 saves. The 1.5 sp2 post dated 15 December 2024 separately describes vanilla export for the legacy client. Shared worlds are live sessions, not backups or public server addresses.

The official play FAQ documents EPK import/export and vanilla 1.8 ZIP transfer for EaglercraftX 1.8. These capabilities are not limited to the legacy 1.5 sp2 news item; no transfer was executed for this guide.

Back up and transfer a 1.8 world

• Use the client's world export control and save the exported file outside browser storage before troubleshooting or changing devices.
• Use EPK for a transfer between compatible Eaglercraft clients. Use the documented ZIP route when transferring to or from vanilla Minecraft 1.8, not a newer 1.21 save.
• On the destination client, use its import control and check a copy of the world before deleting the original. Keep the export even after import succeeds.
• The source and destination must have compatible world formats. These steps do not certify 1.12.2 or 26.2 imports.

Invite friends to a 1.8 shared world

• The host opens a singleplayer world's pause menu and selects Invite, as documented in the project FAQ.
• Friends use Multiplayer, Direct Connect, then Join Shared World and enter the invite code. Do not paste that code into a public server address field.
• If joining fails, compare the relay selected in Network Settings on every participant's client. The host must keep the session available.
• The project worlds directory lists shared sessions; eaglercraft.com/servers lists public servers. Neither list is a backup of your local world.
