ItemPhysic Full

ItemPhysic Full changes how dropped items behave: items float, only burnable items burn in lava or fire, and cactus no longer destroys them. It also adds custom pickup and throwing, igniting items, a configurable despawn time and enhanced item animation.

This full version has to be installed on the server (for vanilla servers there is ItemPhysic Lite) and requires CreativeCore. Available for Forge, NeoForge and Fabric, Minecraft 1.12.2 - 26.3.

Since it needs to live server-side anyway, Minecraft Server Hosting with a panel lets you add it in a single click.
