Configuration Made Easy

You have full control over how the mod behaves. You can find the config file here: - Fabric: `<server>/config/doublejumpenchant-server.toml` - Fabric: `<server>/config/doublejumpenchant-server.json`

Config Options: - `levelBoosts` — A list of jump strengths. The number of values you put here automatically determines how many levels the enchantment has! - `allowBookUpgrades` — Turn on/off the ability to combine books on an anvil. - `anvilUpgradeExperienceCost` — Set the exact XP level cost for combining books. - `treasureBooksEnabled` — Enable/disable chest generation for Double Jump books. - `treasureBookChance` — Global chance to add the Double Jump loot pool. - `treasureBookMinRolls` — Minimum rolls for that loot pool. - `treasureBookMaxRolls` — Maximum rolls for that loot pool. - `treasureBookLevelWeights` — Per-level weights (e.g. [6, 3, 1]). - `treasureBookLootTables` — List of loot tables where books may appear. - `treasureOnlyEnchantment` — If true, Double Jump is treated as treasure-only (not obtainable from the enchanting table).

Default Setup: Out of the box, the mod is balanced with 3 tiers and anvil upgrades enabled: ```toml levelBoosts = [0.38, 0.47, 0.54] allowBookUpgrades = true anvilUpgradeExperienceCost = 8 treasureBooksEnabled = true treasureBookChance = 0.12 treasureBookMinRolls = 1 treasureBookMaxRolls = 1 treasureBookLevelWeights = [6, 3, 1] treasureOnlyEnchantment = false ```

How Anvil Upgrades Work

If you have `allowBookUpgrades` set to `true`, players can combine books of the same tier to reach the next level: - `Double Jump I` + `Double Jump I` ➔ `Double Jump II` - `Double Jump II` + `Double Jump II` ➔ `Double Jump III` *(Players can only craft up to the highest level you've defined in your config).*

For Modpack Creators

- Under the hood, the enchantment is registered with support for up to 10 levels. This means you can easily add or remove levels via the config without ever needing to rebuild the `.jar` file. - In normal survival gameplay, the mod strictly follows the levels defined in your `levelBoosts` config. - If an admin uses a command to give a player a level higher than your config allows (e.g., Level 5 when only 3 are configured), the jump strength will safely cap out at your highest configured value.
