C-erva Core

🧱 C-erva Core

Shared utility library for C-erva Fabric mods.

C-erva Core provides a set of common building blocks — text formatting, registration helpers, networking, inventory utilities, permissions, and more — so that individual mods stay small and don’t reinvent the wheel.

You don’t use this mod directly. Install it as a dependency when another mod (e.g. PhotoChat) requires it.

📦 What’s inside

💬 CervaText

Prefixed chat messages with consistent styling.

CervaText.success("MyMod", "Item given!");   // [MyMod] Item given!  (green)
CervaText.warning("MyMod", "Low durability"); // [MyMod] Low durability  (yellow)
CervaText.error("MyMod", "Not found");        // [MyMod] Not found  (red)

🏷️ CervaRegistry

One-liner registration for identifiers, items, blocks, sounds, and entity types.

CervaRegistry.id("mymod", "ruby");
CervaRegistry.item("mymod", "ruby", new Item(settings));
CervaRegistry.sound("mymod", "ding");

🌐 CervaNetworking

Broadcast a custom payload to all players who have the mod, with an automatic text fallback for everyone else.

CervaNetworking.broadcastWithFallback(server, TYPE, payload, fallbackText);

🎒 CervaItems

Inventory helpers — give items, drop stacks, count slots, check for space.

CervaItems.give(player, stack);         // give or drop if full
CervaItems.hasSpace(player, stack);     // check before giving
CervaItems.countItem(player, Items.DIAMOND);

🔐 CervaPermissions

Simple permission checks for commands and players.

CervaPermissions.hasPermission(source, permission);

🌍 CervaWorld

World and sound utilities.

CervaWorld.playSound(world, pos, soundEvent);
CervaWorld.isServerWorld(world);

⏱️ CervaCooldowns

UUID + key based cooldown map with automatic expiry.

if (CervaCooldowns.isReady(player.getUuid(), "ability", 60)) {
    // 60-tick cooldown passed
}

🖼️ CervaTooltips (client)

Tooltip builder for item descriptions.

CervaTooltips.builder()
    .line("Rare artifact", Formatting.GOLD)
    .line("+5 attack", Formatting.GREEN)
    .build(tooltip);

📁 CervaPaths

Path parsing with quote and space support — useful for commands that accept file paths.

📂 CervaFilePicker (client)

Native OS file dialog via TinyFD — open/save dialogs with format filters.

🛡️ CervaSafe

Quick checks for client/server side, null world, null player — guards against common crashes.
