# Load Player By Name<\/p>\n
Minecraft stores the player data by their UUIDs, but the UUIDs in online mode servers (provided by Mojang’s official API) are different with the one generated offline.<\/p>\n
This cause issues when you want to change online\/offline mode while not affecting your players’ data<\/p>\n
## How This Plugin Works<\/p>\n 1. It stores an name to UUID association table ## Cases<\/p>\n – Server was online mode, plugin not installed – Plugin installed ## Notes<\/p>\n – I don’t know what will happen if you switch between modes and a player change their username at the same time Makes switching between online mode and offline mode much easier!<\/p>\n","protected":false},"featured_media":94867,"template":"","meta":{"_minecraft_slug":"load-player-by-name","_minecraft_project_id":"KdMVGQVs","_minecraft_author":"Hueeey","_minecraft_license":"LicenseRef-All-Rights-Reserved","_minecraft_downloads":441,"_minecraft_follows":3,"_minecraft_client_side":"unsupported","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"load-player-by-name.zip","_minecraft_size_bytes":6064,"_minecraft_version_count":1,"_minecraft_updated_at":"2026-05-16T10:49:06.751611Z","_minecraft_date_created":"2024-12-30T07:29:32.777978Z","_minecraft_date_modified":"2024-12-28T11:04:42.605606Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/load-player-by-name","_minecraft_icon_attachment_id":94867,"_minecraft_imported_at":"2026-06-05T10:22:30+00:00","_minecraft_import_hash":"d0beaa9e30708ed111854d3df078905a","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[124,127,129],"mod_loader":[130,132,134],"minecraft_version":[62,37,73,74,38],"class_list":["post-94866","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-bukkit","mod_category-paper","mod_category-spigot","mod_loader-bukkit","mod_loader-paper","mod_loader-spigot","minecraft_version-1-21","minecraft_version-1-21-1","minecraft_version-1-21-2","minecraft_version-1-21-3","minecraft_version-1-21-4"],"yoast_head":"\nI guess you don’t care about this<\/summary>\n
\n2. When a player joins:
\n – We receive an UUID of the player (new ID)
\n – Look the player name in the table and get the old ID
\n – If not present, try getting the Mojang official UUID as old ID
\n – If even the official ID isn’t present
\n – It’s a new offline player, ignore
\n – Try to move the player data from old ID to new ID
\n – If succeeded, it will kick the player once, and prompt them to rejoin immediately
\n3. When a player quits:
\n – Update the association table

\n > You can switch between modes with ease, without player data lossing<\/p>\n
\n– I sometimes spell the plugin `LoadByPlayerName`, well, doesn’t matter I guess<\/p>\n","protected":false},"excerpt":{"rendered":"
