diqezit/jarsmartfill

This is a small mod for the survival game 7 Days to Die that fixes a specific water collecting exploit. It targets game version 3.0 and is built using Harmony, a common tool for patching game code without editing the original game files. In the normal game, filling a whole stack of empty jars with water only ever costs the water of a single jar, no matter how many jars are in that stack. For big water sources like rivers and lakes this barely matters, since there is effectively unlimited water there anyway. But for small sources like puddles, it means a player can refill an 80 jar stack over and over from a puddle that should only realistically supply one or two jars. The mod keeps the same one click convenience the base game has. Filling a full stack of jars still happens in a single action. What changes is how much water is actually taken from the source. The mod splits water sources into two groups. Large sources such as rivers and lakes are left alone and treated as unlimited, exactly like vanilla, so there is no added cost or extra calculation there. Small sources such as puddles and ponds are handled differently: the mod checks how much water is actually nearby, works out how many jars that amount can genuinely fill, and only fills that many. Any jars beyond that stay empty rather than being given out half filled. The search radius for nearby water grows slightly as a player tries to fill more jars, but it is capped so it never scans an unreasonably large area. The mod ships with a small configuration file that speeds up the jar filling delay and makes sure the setting that allows water to be removed from the world is turned on for the jar item, without overriding other mods that may have already set it. By default the mod only affects the game's standard empty jar item, but a modder can extend it to cover a custom water container item by editing one line in the source code and adding a matching configuration entry, so other mods' water containers can get the same fair filling behavior. Installation is the standard process for this game: extract the mod folder into the Mods directory. No extra setup is described.
