Lava Source Control is a lightweight Minecraft datapack that allows players to toggle lava source conversion on and off, making lava behave the same way as water when the feature is enabled. This allows lava source blocks to be created from adjacent sources using standard water-style mechanics, while disabling it restores vanilla lava behavior. The datapack includes three functions: lava_conversion_on to enable the behavior, lava_conversion_off to disable it, and toggle to switch between the two states. Use /function ns:lava_conversion_on to enable the feature, /function ns:lava_conversion_off to disable it, or /function ns:toggle_lava_conversion to switch states. It provides clear in-game feedback, persists its setting across reloads, works without mods, and applies globally to the world. The datapack is built for Minecraft 1.21.x and has been tested on 1.21.11.
