AutoSwitch Enchant

Author: BaXy

Automatic tool switching based on enchantment rules for Minecraft 1.21.10 (Fabric).

Features

Automatic Switching — the mod automatically selects the right tool when you start mining a block
Enchantment Rules — configure which enchanted tool to use for each block
- Efficiency 1–10 (supports mods with levels above the vanilla maximum)
- Silk Touch
- Fortune 1–3
Smart Haste Awareness — rules with the considerHaste flag only activate when the Haste effect is active, saving tool durability
Tool Type — choose which tool the rule applies to: pickaxe, shovel, axe, hoe, sword, shears, or any
Instant-Mine — the mod calculates mining speed accounting for Efficiency, Haste, and Mining Fatigue, and picks the tool with the minimum level sufficient for instant mining
Rule Priority — Silk Touch > Fortune > Efficiency
Tool Return — optionally switch back to the previous hotbar slot after mining
Configuration Profiles — create and switch between multiple config profiles
Base64 Import/Export — share your settings with other players via a Base64 string
Minecraft Keybind Settings — two reassignable keys in the "AutoSwitch" category:
- B — open the config menu
- H — toggle the mod on/off
ModMenu Integration — access settings through the ModMenu mod list
12 Languages — EN, RU, UK, DE, FR, ES, IT, PL, PT-BR, KO, JA, ZH-CN

You create rules like: "For Stone — Pickaxe with Efficiency 5 + Haste"
When you start breaking a block, the mod checks:
- Do you have the Haste effect?
- Is the Efficiency level high enough for instant mining?
- Which tool in your inventory is the best match?
The mod automatically switches your hotbar slot to the optimal tool
If tool return is enabled — it switches back to the previous tool after mining

Stone (hardness 1.5) requires a mining speed ≥ 45 for instant mining.

Situation	Pickaxe	Speed	Instant?
No Haste	Eff 5 Diamond	~45	Barely
Haste II	Eff 5 Diamond	~63	Yes
No Haste	Eff 10 Diamond	~126	Yes

The mod will choose Eff 5 if you have Haste (saving durability!), and Eff 10 if you don't have Haste.

In-game: press B (default) or open via ModMenu
Toggle key: press H (default) — toggles the mod on/off with an action bar notification
In Minecraft settings: Options → Controls → Key Bindings → "AutoSwitch" category
