* Begin to implement extended world heights: - Implemented in Bukkit module (and where required in Core module) * Implement extended world heights into core module * Add min gen height to setup, * Default gen/build heights based on minecraft version * Few fixes * Fix up queues * Address comments * Make road schematic stuff slightly more efficient by sharing queues * Minor fixes, don't overlay error many times for the same y * Fix incorrect schematic paste height, undo changes to HybridUtils * Overhall regenallroads method to make it work, make sure BukkitChunkCoordinator can/will finish * Process chunks in order when regenerating all roads * Address comments * Address comments * Ground level//bedrock is at min gen height - Add comment on == rather than <= being used - It's because it's only checking for the bedrock layer being broken if that's disabled * Fix offset for min build height in SchematicHandler * Better javadoc Co-authored-by: Hannes Greule <SirYwell@users.noreply.github.com> * Address inclusivity issues for max world height * Javadocs/comments/deprecation * Use world min/max heights if present in QueueCoordinator * Address some deprecations for regions and biome setting * Add a count for chunks we're currently trying to load to not skip chunks at the end of a queue's edit * Use minGenHeight + 1 rather than build height in AugmentedUtils * Create utility method for layer index in GenChunk * Correct height in HybridUtils, also use minGenHeight + 1 * Don't magically split to 128 height in regeneration * Add utility methods for world height in QueueCoordinator * Clean up ClassicPlotManager road creation/removal * Start generation at min gen height if bedrock is disabled * min gen height is set in PlotArea * Add note on schem y normalisation * Improve plot getVolume method readability * Don't overly extend height when regenerating road region * y index utility method in ChunknQueueCoordinator * Layer index utility method in LocalChunk * Use version min/max heights if world not present in QueueCoordinator * Fix min -> max * Don't allow players to modify outside build height when using plot set / schematics. - Also fixes schematic height issues * Remove debug * Address comments * Switch loadingChunks to AtomicInteger to be safe (in case of multi-threaded) * Fix "security" issue that was already present * Ensure sign isn't physicsed Co-authored-by: Hannes Greule <SirYwell@users.noreply.github.com>
