Description
Minecraft Bedrock Mobile – Offhand Swap Add-on Create a Minecraft Bedrock Edition Behaviour Pack for Android and iOS that adds an offhand swapping feature. Main Controls: - Hold the Sneak button. - Press the Place button while sneaking. - Swap the selected hotbar item with the offhand item. - If the offhand is empty, move the selected item into it. - Normal Place functionality must remain unchanged when not sneaking. Requirements: 1. Support Minecraft Pocket Edition mobile touchscreen controls. 2. Use JavaScript and the official "@minecraft/server" Script API. 3. Detect Sneak + Place using supported input events. 4. Preserve item quantities, durability, and metadata where supported. 5. Prevent item duplication, deletion, and accidental repeated swaps. 6. Support compatible offhand items, respecting Minecraft restrictions. 7. Add a short cooldown and actionbar feedback. 8. Support multiplayer with independent player inventories. 9. Keep the add-on lightweight and stable. 10. Include proper error handling and compatibility checks. Deliverables: - Complete "manifest.json". - "scripts/main.js". - All required Behaviour Pack files. - Installation instructions. - Minecraft version compatibility information. - Testing instructions. - A packaged ".mcpack" file. Important: Do not invent unsupported API functions. If direct mobile Place-button detection is unavailable, explain the limitation and implement the closest reliable alternative. Prioritize the exact Sneak + Place offhand swapping experience.

Pocket Offhand Swap
Quickstart
- Import the add-on and activate its Behavior Pack for your world.
- Select an item in your hotbar.
- Hold Sneak, then tap to use/place or interact with a block. The selected item and your offhand item swap. If your offhand is empty, the selected item moves there.
- Check the actionbar for the result.
There is no item to craft or obtain. The swap uses supported sneaking interactions, not a dedicated Place-button press; while sneaking, the triggering interaction is canceled. Without Sneak, normal use and placement work as usual.
Overview
Pocket Offhand Swap lets you move items between your selected hotbar slot and the offhand. It works per player, so each player swaps items in their own inventory.
How To Use
- To put an item in your offhand, select it in the hotbar and trigger a supported interaction while sneaking.
- To take an offhand item back, trigger the swap with an empty selected hotbar slot.
- To exchange two items, select the hotbar item you want to trade with the offhand item, then trigger the swap.
- Wait briefly between swaps: a 12-tick cooldown prevents rapid repeated transfers.
Minecraft’s offhand restrictions still apply. If the selected item cannot be equipped in the offhand, the swap is rejected. The actionbar reports success or messages such as That item cannot be held in the offhand or Both hands are empty. Items retain their quantities and supported item data when swapped.
How to install
Download the mod and follow the step-by-step installation guide.
