Map downloader - A host or dedicated server now tells joiners which Thunderstore package its map comes from (the Mods folder name plus manifest.json). - A player without the map gets a card: icon, name, author, version and description, with DOWNLOAD and CANCEL. It works with mouse, keyboard and controller. - Only packages listed as Maps in the ReSkate community are offered, and never deprecated, rejected or NSFW ones. - On yes the package is downloaded, installed into Mods and applied as a live mod, then the session loads the map. A small card on the right shows the progress, so the player can keep skating. - The player stays connected while it downloads: the host gives a player who says they are fetching the map up to 45 minutes instead of the usual load time. - When the server changes map with the player in it, the card says so. - Protocol version 47: map package on map_offer and world_state, and a "fetching the map" flag on map_request and world_ready. Joining - The pause-menu server browser shows a CONNECTING card over the page while a join is under way, and a COULDN'T CONNECT card with the reason when it does not get in. - The session and voice tabs no longer show before the player is in. - Leaving without the map (declined or cancelled download) no longer counts towards the failed-join limit, on servers and player hosts. Input - A card that asks something holds the game's input until the buttons are released. - Steam's overlay hooks XInput in front of ReSkate and answers the game itself, so a controller reached the game behind menus. ReSkate now hooks that hook as well. Mod merging - Mods are read on several threads, at launch and for live merges. A live merge runs below the game's priority. - The paid-cosmetics check reads the game's files and the mods on several threads. - A live merge reuses the paid-cosmetics verdicts it already has and reports its progress and timings. Launcher - NSFW mods and their categories are not shown in the mod browser.
