Volumetric is an API that I'm working on in an attempt to emulate the Unreal Development Kit's volume features within Minecraft and make region-based plugins a bit more friendly and efficient. I'll briefly explain what a volume is, then go into a few examples. What is a Volume? A volume is a defined region of gamespace that has mutators applied to modify behavior within the volume. UDK supports volumes for almost everything including post-process filters, portals, alternate physics zones, and event-based programming. Currently, the supported volume shapes are as follows: Cuboid Spherical Cylindrical Though, the most advanced features of the UDK's volume system would never work within the limitations of Minecraft, I'm firm in the belief that a standardized volume API would be a step in the right direction for a lot of plugins. Current Supported Events: I'm working on expanding functionality once I deem that new events can be implemented without unreasonably increased overhead. onPlayerEnterVolume onPlayerLeaveVolume onPlayerInsideVolume onBlockPlaceWithinVolume onBlockDestroyWithinVolume Potential Events: onEntityEnterVolume onEntityLeaveVolume Practical Applications: In order to demonstrate the effectiveness, efficiency, and versatility of this system, I'm currently working on designing a set of volumes using the API. Portal Volume: Upon entering a portal volume, a player is transported to either a defined point or another portal volume. Gravity Lift Volume: Players inside a volume will ascend at a definable speed. Mirror Volume: All block changes made in Volume A will be reflected instantly within Volume B. Reset Volume: All block changes within a region can be reverted either upon a triggering event or at a specified interval. Heal Volume: All players within a volume will be healed st a specified interval Protection Volume: Basic protections implementation within a defined volume. Purchasable Plot Volume: Basic demonstration to display how a town plugin could take advantage of volumes Message Volume: Players receive a message upon entering or leaving a volume. How Does it Work? I'm still working out the exact specifications for programmers adding their own custom volumes, but at the moment, you use Bukkit's facility for obtaining a plugin reference for "Volumetric" and using a method to obtain Volumetric's volume manager. Volumetric's volume manager centralizes serialization, storage, and retrieval of volumes and abstracts the majority of the code behind handling volumes. This should cut down on the annoyance and wastefulness of having to define cuboids with each plugin that supports region-based effects or control. Current Status At the moment, the project is very much in the proof of concept stage, but fresh code and documentation will be available on Github at: https://github.com/loganwm/Volumetric-API Small update: The first proof of concept revision of the code is online at github [https://github.com/loganwm/Volumetric-API] and a video demonstrating a simple Mirror Effect applied to a volume has been uploaded to youtube.
