  1. For lack of a better place to put this. Basically some means of shedding light on those finished or mostly finished mods trying something more drastic than a mere skillgain increase. More emphasis on gameplay and how the players are reacting than say the technical documentation that can be found deeper in the WU forums. For example, I only recently learned of a mod working on a whole Vampires/Hunter system.
  2. This is the first part of a series of articles on the "physics and astronomy" of the universe of Wurm Online, trying to describe the structure, dynamics and "laws of nature" of our in-game world . The information compiled here has been carefully researched and discussed by a small group of players who call themselves "The Wurm Astronomical Society" (Docterchese, McGarnicle, Valdor, WojorowskiPL and Yaga). Part 1 summarizes all we know about the basic dimensions of the Wurm universe: tiles, distances, slopes and heights. Part 2 is here: http://forum.wurmonline.com/index.php?/topic/143679-the-wurm-universe-part-2-time-date-and-calendar/ The most basic unit of measurement is defined by the size of a tile. Tiles are the equally sized squares that the landscape of Wurm Online is entirely composed of. In the 3D world of Wurm a tile can be either flat or inclined, so that one or more of its corners can be higher or lower than the others. In all our calculations we used the following fundamental information, given in the Wurmpedia (http://www.wurmpedia.com/index.php/Tile) : How can we measure distances and heights in Wurm? Originally we tried to use a spyglass, because it displays the distance between the observer and an object pointed to by the crosshairs: Using a spyglass is sufficient to verify the basic unit of measurement (1 tile = 4m x 4m) and to measure linear distances within a reasonable accuracy. However, when it comes to measuring heights it turned out that a spyglass is not quite accurate enough to yield reliable results. Thus we need to use a more precise method: triangulation! This method uses basic trigonometric functions to determine the height of an object. To determine the height H of an object, you define a reference point, take a screenshot (as shown in the example) and measure the angle α between the ground and the top of the object, as seen from the reference point. (As we have no means to measure angles in-game, we need to use a graphics program to determine the angle on the screenshot.) Additionally you need to measure the horizontal distance, which you obtain by counting the number of tiles T (remember: one tile corresponds to a distance of 4 meters). You then get the height H by using this formula: Here is an example: For a distance of 40 tiles (T=160m) we measure an angle of 14°. Thus, our avatar of Magranon would have a height of: H = 160m x tan(14°) = 40m (Please note that the result has to be rounded, due to the immanent inaccuracy of this method.) Here is a list of heights for some arbitrary objects, just to give some examples (sorry, this forum doesn't provide tables): Player character: 1.7m House wall (1 floor): 3.0m (note: the ground floor of a house has a height of 3.3m) Pillar: 5.6m Freedom tower (incl. flag): 25m Colossus: 34m Deity avatar 40m Finally, talking about measuring heights, we must look at another basic unit of measurement used in the Wurm universe: dirts. Whenever we see sloped tiles defining the 3D landscape the elevation of slopes is given in terms of the amount of "dirts dropped". When terraforming the land you use a shovel to dig or drop dirt - you add or subtract one "unit of dirt" with each action of the shovel. Using the method of triangulation described above we can find out how these "units of dirt" correspond to metric units. By dropping dirt we make elevated platforms of various heights, thus creating different slopes. We then position an observer in a pit, so that the eye level is slightly above the ground, and take screenshots: .. Measuring the angles and using the formula given above, we can triangulate the elevation of the platform: .. We obtain the following table (for slopes spanning a single tile): Slope .. Angle .. Elevation (m) ---------------------------------------- 10 ...... 14.0 .... 1.0 20 ...... 26.6 .... 2.0 30 ...... 36.9 .... 3.0 40 ...... 45.0 .... 4.0 50 ...... 51.3 .... 5.0 60 ...... 56.3 .... 6.0 70 ...... 60.3 .... 7.0 80 ...... 63.4 .... 8.0 90 ...... 66.0 .... 9.0 100 ..... 68.2 ... 10.0 150 ..... 75.1 ... 15.0 200 ..... 78.7 ... 20.0 Thus, there is a simple relation between "dirts" and metric units: Using this method it is also possible to determine the height of a player character with sufficient accuracy: We plan to continue this series with the following chapters: "Part 2: Time, Date and Calendar" "Part 3: The planet Wurm (Basic Physics)" "Part 4: Sky and Stars (Basic Astronomy)" "Part 5: Sol and the Moons (Celestial Mechanics of the Solar System)" .... etc......

  3. This is the second part of a series of articles on the "physics and astronomy" of the universe of Wurm Online, trying to describe the structure, dynamics and "laws of nature" of our in-game world . Part 2 summarizes all we know about time in the Wurm universe: units of time measurement and the calendar. Part 1 is here: http://forum.wurmonline.com/index.php?/topic/121902-the-wurm-universe-part-1-basic-metrics/ One of the first things we notice when observing the world of Wurm Online is the rapid succession of day and night: a full day-night cycle only lasts 3 hours of our real-world time. Thus, we conclude that the planet Wurm rotates rapidly around its axis: 8 times faster than our Earth. (At this point, I will not discuss the physical implications of this observation, nor will I speculate on the possible reasons for the rapid planetary rotation. This will probably be done in one of the following parts of this series.) (By “day” we mean one full planetary rotation, i.e. a complete “day-night cycle”.) Just like in our real world, the rotation of our planet determines how we measure time. In the Wurm universe, instead of saying that a full planetary rotation lasts 3 hours, it was agreed to split the day-night cycle into 24 time units, called “Wurm hours”. (Bear in mind that this is only an arbitrary convention – we could also have agreed on a Wurm rotation having 12 or 30 “Wurm hours”. By choosing the number 24 we just made it easier for us, because now there are as many “Wurm hours” in a “Wurm day” as there are real hours in an Earth day.) Once we made that definition, it is clear that: It must be noted that this definition has caused a common misunderstanding. On the forums (and even on Wurmpedia) you can sometimes read that “Wurm time passes 8 times faster than real time”. This is not true! Time in the Wurm universe is the same as time in our real world – we only use a unit of time measurement which is 8 times smaller than in real life! (It is the same effect as if you defined a new unit of length – say: “1 Wurm meter”, corresponding to 25 real centimeters - and you would say that a 1-meter ruler has a length of “4 Wurm meters”. This doesn’t make the ruler 4 times longer than it was before!) You can easily see that Wurm time passes at the same rate as real time by watching the speed indicator below the GUI status window: Let your character run a while and count the number of tiles you cross in a given length of time. Considering that 1 tile corresponds to 4 meters (see part 1 of this series) you will easily see that the speed indicated in the GUI uses “real time” instead of some kind of pseudo “accelerated time”. If we take a closer look at the 3 hours defining a full “Wurm day”, we find that Sol (the sun of our planet Wurm) rises at 04:30 (Wurm time) and sets at 19:30 (Wurm time) each day. That’s why the time between about 20:00 and 04:00 is dark (“night”), and the time between 04:00 and 20:00 is bright (“day”). Now that we have defined the “Wurm day” and the “Wurm hour”, we also observe that the visual appearance of Wurm’s nature changes as time passes. Just like in real life, we experience 4 different seasons, called “winter”, “spring”, “summer”, and “autumn”. These seasons reoccur regularly after 336 Wurm days. Thus we can define the “Wurm year”: This is a convenient number, because 336 = 7 x 4 x 12, allowing us to split a Wurm year into 12 months (called “starfalls”), each with 4 weeks of 7 days. The 7 days in a Wurm week are called: 1. day: Day of the Ant 2. day: Day of theLuck 3. day: Day of the Wurm 4. day: Day of the Wrath 5. day: Day of the Tears 6. day: Day of the Sleep 7. day: Day of the Awakening The 12 starfalls are called: 1. starfall: Diamond 2. starfall: Saw 3. starfall: Digging 4. starfall: Leaf 5. starfall: Bear 6. starfall: Snake 7. starfall: White shark 8. starfall: Fire 9. starfall: Raven 10. starfall: Dancer 11. starfall: Omen 12. starfall: Silence This is the Wurm calendar, showing days, weeks, starfalls, and the seasons: We plan to continue this series with the following chapters: "Part 3: The planet Wurm (Basic Physics)" "Part 4: Sky and Stars (Basic Astronomy)" "Part 5: Sol and the Moons (Celestial Mechanics of the Solar System)" .... etc......
