can contain transform and\n kinematic reference information for all planetary systems in DualUniverse.\n Each planetary system is identified by a numeric identifier. Currently,\n the only planetary system, Helios, has the identifier: zero. This \"class\"\n supports the indexing ('[]') operation which is equivalent to the\n use of the 'getPlanetarySystem' method. It also supports the 'pairs()'\n method for iterating over planetary systems.\n\n An instance of the 'PlanetarySystem' \"class\" contains all reference\n information for a specific system. It supports the indexing ('[]') and\n 'pairs()' functions which allows iteration over each \"body\" in the\n system where the key is the numeric body ID. It also supports the\n 'tostring()' method.\n An instance of the 'BodyParameters' \"class\" contains all reference\n information for a single celestial \"body\" (a moon or planet). It supports\n the 'tostring()' method, and contains the data members:\n planetarySystemId - numeric planetary system ID\n bodyId - numeric body ID\n radius - radius of the body in meters (zero altitude)\n center - world coordinates of the body's center position\n GM - the gravitation parameter (g = GM/radius^2)\n Note that the user is allowed to add custom fields (e.g. body name), but\n should insure that complex table values have the '__tostring' metamethod\n implemented.\n Transform and Kinematics:\n \"World\" coordinates is a cartesian coordinate system with an origin at an\n arbitrary fixed point in a planetary system and with distances measured in\n meters. The coordinates are expressible either as a simple table of 3 values\n or an instance of the 'vec3' class. In either case, the planetary system\n identity is implicit.\n \"Map\" coordinates is a geographic coordinate system with an origin at the\n center of an identified (by a numeric value) celestial body which is a\n member of an identified (also a numeric value) planetary system. Note that\n the convention that latitude, longitude, and altitude values will be the\n position's x, y, and z world coordinates in the special case of body ID 0.\n The kinematic parameters in the reference data permit calculations of the\n gravitational attraction of the celestial body on other objects.\n Reference Data:\n This is an example of reference data with a single entry assigned to\n planetary system ID 0, and body ID 2 ('Alioth'):\n referenceTable = {\n [0] = { [2] = { planetarySystemId = 0,\n bodyId = 2,\n radius = 126068,\n center = vec3({x=-8, y=-8, z=-126303}),\n GM = 1.572199+11 } -- as in F=-GMm/r^2\n }\n }\n ref=PlanetaryReference(referenceTable)\n Collecting Reference Data:\n A combination of information from the \"Map\" screen in the DU user interface,\n and values reported by the DU Lua API can be the source of the reference\n table's data (planetarySystemId, bodyId, and surfaceArea is from the user\n interface):\n referenceTable = {}\n referenceTable[planetarySystemId][bodyId] =\n PlanetaryReference.createBodyParameters(planetarySystemId,\n bodyId,\n surfaceArea,\n core.getConstructWorldPos(),\n core.getWorldVertical(),\n core.getAltitude(),\n core.g())\n Adapting Data Sources:\n Other sources of data can be adapted or converted. An example of adapting a\n table, defined in the file: 'planets.lua', containing information on a single\n planetary system and using celestial body name as the key follows (note that\n a 'name' field is added to the BodyParameters instance transparently after\n construction, and the '__pairs' meta function is required to support the\n 'closestBody' and '__tostring' methods):\n ref=PlanetaryReference(\n {[0] = setmetatable(require('planets'),\n { __index = function(bodies, bodyId)\n for _,v in pairs(bodies) do\n if v and v.bodyId == bodyId then return v end\n end\n return nil\n end,\n __pairs = function(bodies)\n return function(t, k)\n local nk, nv = next(t, k)\n if nv then\n local GM = nv.gravity * nv.radius^2\n local bp = BodyParameters(0,\n nv.id,\n nv.radius,\n nv.pos,\n GM)\n bp.name = nk\n return nk, bp\n end\n return nk, nv\n end, bodies, nil\n end })\n })\n\n Converting Data Sources:\n An instance of 'PlanetaryReference' that has been adapted to a data source\n can be used to convert that source to simple table. For example,\n using the adapted instance shown above:\n load('convertedData=' .. tostring(ref))()\n newRef=PlanetaryReference(convertedData)\n Also See: kepler.lua\n ]]--\n--[[ START OF LOCAL IMPLEMENTATION DETAILS ]]--\n-- Type checks\nlocal function isNumber(n) return type(n) == 'number' end\nlocal function isSNumber(n) return type(tonumber(n)) == 'number' end\nlocal function isTable(t) return type(t) == 'table' end\nlocal function isString(s) return type(s) == 'string' end\nlocal function isVector(v) return isTable(v)\n and isNumber(v.x and v.y and v.z) end\nlocal function isMapPosition(m) return isTable(m) and isNumber(m.latitude and\n m.longitude and\n m.altitude and\n m.bodyId and\n m.systemId) end\n-- Constants\nlocal deg2rad = math.pi/180\nlocal rad2deg = 180/math.pi\nlocal epsilon = 1e-10\nlocal num = ' *([+-]?%d+%.?%d*e?[+-]?%d*)'\nlocal posPattern = '::pos{' .. num ..

    ----Older Version In Multiple formats for Learning Purposes. DU IT
    Space Map with Warp Calculation
    Credits to All of DU Lua Community

    Requirements:
    1 Dynamic Construct
    1 Screen
    1 Program Board

    Link Screen then Core

    Two Versions are available and do the same thing.
    One uses variables and math with some built in functions from Lua to get the values.
    One uses Functions from JayleBreak's atlas and functions to get the values.
     

    *KNOWN BUGS*
    ----On fresh login, Core has to be ran one time to send Construct weight data over the server, otherwise math will be wrong.
    So sit down in pilot seat one time and then run programming board. After that its always set. ---Server Bug

    ----Currently has Bug with Screen Flickers on half of the svg during setHTML redraw update-- 9/23 Patch
     
     

    Planets are organized similar to DU ingame map and are stationary svg.

Description An instance of the 'PlanetaryReference' "class" can contain transform and kinematic reference information for all planetary systems in DualUniverse. Each planetary system is identified by a numeric identifier. Currently, the only planetary system, Helios, has the identifier: zero. This "class" supports the indexing ('[]') operation which is equivalent to the use of the 'getPlanetarySystem' method. It also supports the 'pairs()' method for iterating over planetary systems. An instance of the 'PlanetarySystem' "class" contains all reference information for a specific system. It supports the indexing ('[]') and 'pairs()' functions which allows iteration over each "body" in the system where the key is the numeric body ID. It also supports the 'tostring()' method. An instance of the 'BodyParameters' "class" contains all reference information for a single celestial "body" (a moon or planet). It supports the 'tostring()' method, and contains the data members: planetarySystemId - numeric planetary system ID bodyId - numeric body ID radius - radius of the body in meters (zero altitude) center - world coordinates of the body's center position GM - the gravitation parameter (g = GM/radius^2) Note that the user is allowed to add custom fields (e.g. body name), but should insure that complex table values have the '__tostring' metamethod implemented. Transform and Kinematics: "World" coordinates is a cartesian coordinate system with an origin at an arbitrary fixed point in a planetary system and with distances measured in meters. The coordinates are expressible either as a simple table of 3 values or an instance of the 'vec3' class. In either case, the planetary system identity is implicit. "Map" coordinates is a geographic coordinate system with an origin at the center of an identified (by a numeric value) celestial body which is a member of an identified (also a numeric value) planetary system. Note that the convention that latitude, longitude, and altitude values will be the position's x, y, and z world coordinates in the special case of body ID 0. The kinematic parameters in the reference data permit calculations of the gravitational attraction of the celestial body on other objects. Reference Data: This is an example of reference data with a single entry assigned to planetary system ID 0, and body ID 2 ('Alioth'): referenceTable = { [0] = { [2] = { planetarySystemId = 0, bodyId = 2, radius = 126068, center = vec3({x=-8, y=-8, z=-126303}), GM = 1.572199+11 } -- as in F=-GMm/r^2 } } ref=PlanetaryReference(referenceTable) Collecting Reference Data: A combination of information from the "Map" screen in the DU user interface, and values reported by the DU Lua API can be the source of the reference table's data (planetarySystemId, bodyId, and surfaceArea is from the user interface): referenceTable = {} referenceTable[planetarySystemId][bodyId] = PlanetaryReference.createBodyParameters(planetarySystemId, bodyId, surfaceArea, core.getConstructWorldPos(), core.getWorldVertical(), core.getAltitude(), core.g()) Adapting Data Sources: Other sources of data can be adapted or converted. An example of adapting a table, defined in the file: 'planets.lua', containing information on a single planetary system and using celestial body name as the key follows (note that a 'name' field is added to the BodyParameters instance transparently after construction, and the '__pairs' meta function is required to support the 'closestBody' and '__tostring' methods): ref=PlanetaryReference( {[0] = setmetatable(require('planets'), { __index = function(bodies, bodyId) for _,v in pairs(bodies) do if v and v.bodyId == bodyId then return v end end return nil end, __pairs = function(bodies) return function(t, k) local nk, nv = next(t, k) if nv then local GM = nv.gravity * nv.radius^2 local bp = BodyParameters(0, nv.id, nv.radius, nv.pos, GM) bp.name = nk return nk, bp end return nk, nv end, bodies, nil end }) }) Converting Data Sources: An instance of 'PlanetaryReference' that has been adapted to a data source can be used to convert that source to simple table. For example, using the adapted instance shown above: load('convertedData=' .. tostring(ref))() newRef=PlanetaryReference(convertedData) Also See: kepler.lua ]]-- --[[ START OF LOCAL IMPLEMENTATION DETAILS ]]-- -- Type checks local function isNumber(n) return type(n) == 'number' end local function isSNumber(n) return type(tonumber(n)) == 'number' end local function isTable(t) return type(t) == 'table' end local function isString(s) return type(s) == 'string' end local function isVector(v) return isTable(v) and isNumber(v.x and v.y and v.z) end local function isMapPosition(m) return isTable(m) and isNumber(m.latitude and m.longitude and m.altitude and m.bodyId and m.systemId) end -- Constants local deg2rad = math.pi/180 local rad2deg = 180/math.pi local epsilon = 1e-10 local num = ' *([+-]?%d+%.?%d*e?[+-]?%d*)' local posPattern = '::pos{' .. num ..

can contain transform and\n kinematic reference information for all planetary systems in DualUniverse.\n Each planetary system is identified by a numeric identifier. Currently,\n the only planetary system, Helios, has the identifier: zero. This \"class\"\n supports the indexing ('[]') operation which is equivalent to the\n use of the 'getPlanetarySystem' method. It also supports the 'pairs()'\n method for iterating over planetary systems.\n\n An instance of the 'PlanetarySystem' \"class\" contains all reference\n information for a specific system. It supports the indexing ('[]') and\n 'pairs()' functions which allows iteration over each \"body\" in the\n system where the key is the numeric body ID. It also supports the\n 'tostring()' method.\n An instance of the 'BodyParameters' \"class\" contains all reference\n information for a single celestial \"body\" (a moon or planet). It supports\n the 'tostring()' method, and contains the data members:\n planetarySystemId - numeric planetary system ID\n bodyId - numeric body ID\n radius - radius of the body in meters (zero altitude)\n center - world coordinates of the body's center position\n GM - the gravitation parameter (g = GM/radius^2)\n Note that the user is allowed to add custom fields (e.g. body name), but\n should insure that complex table values have the '__tostring' metamethod\n implemented.\n Transform and Kinematics:\n \"World\" coordinates is a cartesian coordinate system with an origin at an\n arbitrary fixed point in a planetary system and with distances measured in\n meters. The coordinates are expressible either as a simple table of 3 values\n or an instance of the 'vec3' class. In either case, the planetary system\n identity is implicit.\n \"Map\" coordinates is a geographic coordinate system with an origin at the\n center of an identified (by a numeric value) celestial body which is a\n member of an identified (also a numeric value) planetary system. Note that\n the convention that latitude, longitude, and altitude values will be the\n position's x, y, and z world coordinates in the special case of body ID 0.\n The kinematic parameters in the reference data permit calculations of the\n gravitational attraction of the celestial body on other objects.\n Reference Data:\n This is an example of reference data with a single entry assigned to\n planetary system ID 0, and body ID 2 ('Alioth'):\n referenceTable = {\n [0] = { [2] = { planetarySystemId = 0,\n bodyId = 2,\n radius = 126068,\n center = vec3({x=-8, y=-8, z=-126303}),\n GM = 1.572199+11 } -- as in F=-GMm/r^2\n }\n }\n ref=PlanetaryReference(referenceTable)\n Collecting Reference Data:\n A combination of information from the \"Map\" screen in the DU user interface,\n and values reported by the DU Lua API can be the source of the reference\n table's data (planetarySystemId, bodyId, and surfaceArea is from the user\n interface):\n referenceTable = {}\n referenceTable[planetarySystemId][bodyId] =\n PlanetaryReference.createBodyParameters(planetarySystemId,\n bodyId,\n surfaceArea,\n core.getConstructWorldPos(),\n core.getWorldVertical(),\n core.getAltitude(),\n core.g())\n Adapting Data Sources:\n Other sources of data can be adapted or converted. An example of adapting a\n table, defined in the file: 'planets.lua', containing information on a single\n planetary system and using celestial body name as the key follows (note that\n a 'name' field is added to the BodyParameters instance transparently after\n construction, and the '__pairs' meta function is required to support the\n 'closestBody' and '__tostring' methods):\n ref=PlanetaryReference(\n {[0] = setmetatable(require('planets'),\n { __index = function(bodies, bodyId)\n for _,v in pairs(bodies) do\n if v and v.bodyId == bodyId then return v end\n end\n return nil\n end,\n __pairs = function(bodies)\n return function(t, k)\n local nk, nv = next(t, k)\n if nv then\n local GM = nv.gravity * nv.radius^2\n local bp = BodyParameters(0,\n nv.id,\n nv.radius,\n nv.pos,\n GM)\n bp.name = nk\n return nk, bp\n end\n return nk, nv\n end, bodies, nil\n end })\n })\n\n Converting Data Sources:\n An instance of 'PlanetaryReference' that has been adapted to a data source\n can be used to convert that source to simple table. For example,\n using the adapted instance shown above:\n load('convertedData=' .. tostring(ref))()\n newRef=PlanetaryReference(convertedData)\n Also See: kepler.lua\n ]]--\n--[[ START OF LOCAL IMPLEMENTATION DETAILS ]]--\n-- Type checks\nlocal function isNumber(n) return type(n) == 'number' end\nlocal function isSNumber(n) return type(tonumber(n)) == 'number' end\nlocal function isTable(t) return type(t) == 'table' end\nlocal function isString(s) return type(s) == 'string' end\nlocal function isVector(v) return isTable(v)\n and isNumber(v.x and v.y and v.z) end\nlocal function isMapPosition(m) return isTable(m) and isNumber(m.latitude and\n m.longitude and\n m.altitude and\n m.bodyId and\n m.systemId) end\n-- Constants\nlocal deg2rad = math.pi/180\nlocal rad2deg = 180/math.pi\nlocal epsilon = 1e-10\nlocal num = ' *([+-]?%d+%.?%d*e?[+-]?%d*)'\nlocal posPattern = '::pos{' .. num ..

    I'm sorry, this is one of my hot-button issues.  For the life of me, I will just never understand why people think that MMO games should be free.  I just don't get it.  Programmers spend years and years to learn their trade and then years and years to make a game and in the case of games like this, they then pay years and years of sever costs, maintenance and updates to continue providing access.  Not to mention the innovation, risk taking and passion game devs have is unlike any other service that I have ever paid for.   But people still want them to be free?!

    On the other hand, these very same people will buy a $600 phone and agree up front to pay anywhere from $50 -$100 or more per month to use the darn thing for at least two years or they are in breach of contract.   They seem to have no problem paying places like Netflix, Hulu and Amazon $10 a month forever to see reruns of movies that they have, most likely, already seen that took a fraction of the time and money to make and are not near as entertaining as a good MMO.  But no one seems to have a problem with that.   There are tons of similar examples that i won't go into, but I'm sure you get the gist.

    So what is it about games that makes people like you believe that its ok to even suggest that other people work for free and even cover any costs they have to pay to provide you untold hours of free entertainment?   How does anyone think that's a reasonable request?

    I am more than happy to pay 15 - 20 dollars per month for a game like this.   If it is 15 dollars a month and I spend 4 hours per day, that is about 13 cents per hour entertainment value.    If I go to the movies, I can rarely get out for less than 25 dollars...so around 12.50 per hour to entertain me.   And based on how long I spent in EVE, I will probably average a good deal more than 4 hours per day with a game like this.   Heck, I could spend an extra hour working overtime in RL and pay for 3 months of subscription at that price.
