WGenerator Map Generator for Wurm Unlimited Servers Download Here | View Source on GitHub | WGenerator allows you to generate maps for Wurm Unlimited with a large amount of flexibility. Generate a heightmap to suit your tastes, erode it to smooth out the rough edges, and drop dirt on it to build up your desired dirt layer. From there you can add as many biomes as you want for all tile types, restricting biomes to certain height ranges, certain sizes and rarity. Generate an ore map with your desired ore distribution, and save it all with a history of actions taken, map dumps and actual map files needed for servers. If you need to edit or load a previous map, simply edit the text file of saved actions, or load the actions file back into WGenerator and keep working on your map from where you left off. Detailed Instructions HeightMap Generation: Map Size: Map width and height in tiles, defaults to 2048. (Deliverance sized maps are 2048, Independance sized maps are 4096, Xanadu sized maps are 8192). Seed: Seed used to randomize heightmap generation. #: Automatically generate a new seed. Res: Resolution of the heightmap. Higher numbers for large land mass, smaller numbers for smaller islands and archipelagos. Iterations: How many times to pass over the heightmap adding more details. Lower iterations will leave a smoother, less detailed map. Min Edge: The minimum amount of tiles between the borders and first bits of land. Border Weight: How steeply the land will taper off near the borders. Higher number for steeper edges. Max Height: Maximum height for tiles (measured in dirt). More Land: Increases the base height of everything to create more land. HeightMap Erosion: Erosion Iterations: How many times to pass over the map eroding the heights. Erosion Min Slope: Erosion ignores all slopes below this value (measured in dirt). Max Sediment Per Iteration: Amount of sediment that will be moved for each iteration, higher will cause smoother lands faster. Dirt Dropping: Biome Seed: Seed used for random generation in dirt droppng and biome seeding. #: Automatically generate a new biome seed. Dirt Per Tile: How many dirt to drop on each tile total. Max Dirt Slope: Dirt will start flowing downhill above this slope. Max Dirt Slope (Diagonal): Dirt will start flowing diagonally downhill above this slope. Max Dirt Height: No dirt will be dropped above this height. For a few tiles just below this height, a smaller amount of dirt will be dropped. Water Height: The height of the water level (measured in dirt). Biome Generation: Dropdown: What type of tile to place with the biome generation. Tree and bush types will only be placed over other trees and bushes, or on grass tiles. Seed Count: How many initial seeds of the biome to place, each seed will spread to a certain size. Size: How far each seed can possibly spread to depending on growth percentage. Max Slope: Biome will not grow if the slope to the next tile is above this. Min Height: Biome will not grow below this height. Max Height: Biome will now grow above this height. Growth % N/S/E/W: Percentage rates that any tile will spread in a given direction. 100/100/100/100 will make every biome spread in a diamond pattern skipping no tiles. Add Biome: Adds the new biome. Undo Last Biome: Removes the last biome added - only stores the last biome, so can only use this once at a time. Reset Biomes: Reset all biome changes. Ore Generation: Each entry box holds the percentage of tiles that will be a given ore type. Rock is automatically calculated so everything adds up to 100%. Note: Default ore generation values may be very dense, you may want to test this. Saving & Loading: Text Box: Name of the map. All files saved and loaded will be saved to the "./maps/name/" folder from where WGenerator is launched. Save Actions: Saves all actions taken for the current map generation to a text file. Text file can then be edited to remove certain lines, or shared with others etc. Load Actions: Loads the actions file from the current map name directory. All actions will process through the UI in order, so may take a fair bit of time to load and generate everything. Save Image Dumps: Saves the map dump, topography map and cave map to the map name folder. Save Map Files: Saves all map files to the map name folder. If you want to test those maps with WGenerator still running, you may have to click this button twice before copying the maps, else it doesn't save the files completely. Show Map View: Shows the map dump view in the WGenerator window. Show Topo View: Shows the topography map view in the WGenerator window. Show Cave View: Shows the cave view in the WGenerator window. Show Height View: Shows the heightmap view in the WGenerator window. Tips & Tricks Heightmap Erosion and Dropping Dirt both take a fair amount of time to complete. Keep in mind that we're dealing with 4.2million tiles for a 2048x2048 map, and both erosion and dirt dropping are making around ~50 passes over every tile, maybe more depending on your settings. Don't be surprised if everything is taking a long time to complete, especially with large maps. With a (fairly) top end PC, erosion and dirt dropping still take 7-8 seconds each on a 2048 map for me. With older PCs and laptops, that can be at least 30 seconds each, if not longer. If you've clicked a button and the program is hanging, just wait until it completes - the button will stay pressed while everything is working. If you're clicking a button and something isn't finishing properly, e.g. clicking Drop Dirt and it finished in a few seconds with no change, you may be running out of memory. You can run from command line to confirm that. In order to fix that, run the jar from command line specifying how much RAM to use: "java -Xmx2048m -jar WGenerator.jar" where 2048m is how much RAM to use. Remember to check your maps folder fairly often. Map files tend to be saved a fair amount, so if you're generating a lot of maps, a lot of files will be created. Be sure to delete any folders for maps you no longer require, otherwise your storage drives might start getting full fairly quickly. That should be everything. Any questions feel free to ask here. Thanks to Xyp, Vardoj, Keenan and Tathar for testing, changes and feedback over the last few days helping to get this out in time for the WU release.
