Mod «Co-op Enhanced» for The Binding of Isaac
Co-op Enhanced is a massive overhaul of Co-op, adding many features and necessary fixes for a more playable experience.
Co-op HUD
— Renders all vanilla HUD (active items, hearts, pocket items, and trinkets) in a standard position for all four players.
— Press a keybind (H by default) or button combo on P1's controller to switch between Co-Op HUD and the default HUD.
— Efficient rendering code with caches and a configurable refresh rate.
— A plethora of settings are available for Items, Players, Stats, Pickups, Difficulty, Monster Waves, Twins, and more.
— Collectible display with plenty of options to track which player has what.
— Customizable fonts for virtually every text HUD available.
— Angel/Devil/Planetarium/Greed Machine/Library chances — with customizable positions.
— Many HUD options can be set to show only when the Map button is/isn't held down, to help clear some clutter from the screen when not needed.
— Player colors, player heads, and player naming, with many color options to choose from. Use a command to set a custom name.
— Hearts system utilizes Custom Health API to allow for more options and compatibility with other mods that use it.
— Tons of API functions and callbacks for other mods to give compatibility.
— Extremely customizable with lots of options for everything!
Co-op Labels
— Give characters labels to help find them on the screen.
— Grants the ability to tint characters and tears as well.
— Plenty of other options to differentiate your character from others.
Co-op Marks
— Adds completion mark trackers to the pause screen and character select for each player.
— Vanilla-like — they don't appear when no marks have been completed and work almost identically to the vanilla marks.
— Configurable names and colors, and a few other cool options.
Co-op Treasures
— Treasure Rooms now will spawn a pedestal for each player.
— Several options to customize your experience. (e.g. make pedestals be assigned to players, choose how pedestals are assigned)
— Collectibles are seed accurate, meaning if you replay a seed all players will have the same items they did each replay. Works with rerolling, Chaos, Glitched Crown, etc.
— Assigned pedestals will show the label of which player owns what, and will have the appropriate price (if playing Tainted Keeper).
— Works with many special room types, all of which are individually configurable (by default only treasure rooms are enabled).
— Smart item pedestal placement that checks if an area in a room is accessible and clear to help prevent placing pedestals in the void/wall, and clear rocks and other grid entities as needed.
Co-op Extras
— Automatic Pricing! Items will have their prices adjusted according to whichever player is closest. Works with Devil Deals/Black Markets/Treasure Rooms and more, for characters like The Keeper, Lost, Blue Baby, etc. No more making everything expensive because one player is Tainted Keeper.
— Ghost Player Flight! With custom options to prevent ghost players from grabbing pickups from areas they normally couldn't reach, stop them from opening chests, disallow them from purchasing, or even remove the ability to body block enemies (they are ghosts after all).
— Greed Mode Revive Machine! Adds a Revive Machine to the Greed Mode shop that appears near the center on every floor after the first. (Not sure why this isn't vanilla.)
— Sacrifice Room Revives! Dead players can now be revived in Sacrifice Rooms by a living player using it.
Co-op Fixes
— A small Fullscreen tweak that resets the window to 0,0 and refreshes the screen whenever you start/restart a game.
— Fixes an issue where Co-op is prevented from starting. Configurable amount of room visits. (Set to 0 to allow starting Co-op at any point in the floor's starting room)
— Fixes an issue where changing controller order before rejoining a game (or even just rejoining a game) could cause all characters to become the same. This also fixes the HUD not loading for players beyond P1, so disable that option in Isaac Reflourished if you have it.
Co-op Commands
— Give/Remove items
— Change character types
— Modify Health
— Revive Players
