About this project

What does Physics Swapping add?

Physics Swapping replaces the boring vanilla item movement with dynamic, physics-based jumps. Every time you move an item between slots, it bounces, rotates, and behaves differently — no two swaps look the same.

Features

  • Bouncy physics — items jump with gravity and bounce decay.
  • Randomized parameters — each swap has unique height, bounce count, angle, and duration.
  • Smooth rotation — items tilt left and right during the jump.
  • Fully configurable — tweak everything in the config menu.
  • Client-side only — works on any server.

How It Works

When you move an item in your inventory (Shift+click or drag), it doesn't just teleport to the new slot — it bounces in place right where it lands. Each bounce is unique, with random height, angle, and number of bounces.

Preview


Configuration

You can adjust the following parameters in the config menu (Mod Menu required):

Setting Description
Duration How long the jump animation lasts.
Bounces Number of bounces before landing.
Height Maximum jump height.
Angle Maximum rotation angle during the jump.
Size Scale of the item during the animation.
Squash & Stretch Squash and stretch of the item in flight.

All settings are live — no need to restart the game.
