2-- This lua script creates a totally random generated space station for the orxonox computer game!--
[9348]3-- (c) Wallah 2008, published under GPL licence!                                                  --

[9348]7-- IMPORTANT: If you need more parameters, do the following: copy the actual function (just the headline and the end statement) to the end of the file,           --
[5333]8-- like I did with createSpaceStation() and let that function call the new function where you can modify the parameters. For all parameters which the old function--
9-- doesn't have you just give the standard default values, which I have defined. This is to make sure, that anyone else who uses the old function can still use it--
[9348]10-- the same way he/she always did. If you want a function with less parameters, just create a new one at the end of the file and call this function with some     --
11-- default values. REMEMBER: Function overloading is not possible, be sure to call your function differently from others already existing ones.                   --
[5333]12--------------------------------------------------------------------------------------------------------------------------------------------------------------------

14-- This function creates a randomly generated space station.
[5341]15-- The first argument ranSeed, must be 0, or a positive Integer, if it is 0 your space station is always chosen randomly, if you give an integer,
[9348]16--  your space station will be generated randomly, but once you have the space station it will always be the same.
[5333]17-- The argument xLength defines how large the space station will be into the x-direction.
18-- The argument xVar defines how much the space station will vary at the ends in x-direction, this is so that the station is no cube.
19-- The argument yLength is the same as xLength, but for the y-direction.
20-- The argument yVar is the same as xLength, but for the y-direction.
21-- The argument zLength is the same as xLength, but for the z-direction.
22-- The argument zVar is the same as xLength, but for the z-direction.
23-- The argument sSScale scales the station proportionally in all directions.
24function createSpaceStationPar(ranSeed, xLength, xVar, yLength, yVar, zLength, zVar, sSScale)

29-- This prints xml code, which creates a MovableEntity, which I need to attach all the parts of the space station.
30print("<MovableEntity scale=1 position=\"0,0,0\" >")
31-- End create Movable Entity.

37-- Create a randomseed, so that the math.random() function is actually random.
[5341]38if ranSeed == 0 then
[9348]39    math.randomseed(os.time())
[5333]40else
[9348]41    math.randomseed(ranSeed)

49-- Here you can define some global variables, with which you can modify the space station.

51-- Define the maximal size of the grid, this value is based on how large you define the area of bodyparts plus 20 gridpoints for attachparts.
52sSSize=30
53if xLength>=yLength and xLength>=zLength then
[9348]54    sSSize=xLength+20

[5333]57elseif zLength>=xLength and zLength>=yLength then
[9348]58    sSSize=zLength+20
[5333]59end
60-- Define how many parts the space station has, this value has to be exact, so be sure to increment it if you're adding a new part.
61sSParts=9
62-- Define how many body parts the space station has, this value has to be exact. Body part means a part, which has connections at least in two directions.
63sSBodyParts=3
64-- Define how many frontParts you have.
65frontParts=1
66-- Define how many backParts you have.
67backParts=1

71rightSideParts=1
72-- Define how many top parts you have.
73topParts=2
74-- Define how many connection parts you have.
75connParts=1
76-- Define the maximal dimension of a single part, be sure this value is big enough, better it's too big, it's only a matter of efficiency.
77-- It should be at least 1 bigger than the biggest part needs, because I guarantee that it works with odd numbers, to do so I use the math.floor function.
78pDim=6
79-- Define the griddimension, be sure this value matches the size of a single space station part plus the size of a connection part, which means your parts must be:
[9348]80--  integer*(gridDim-connectionSize), then integer tells you how many griddimensions your part is.

88-- This creates a 4-dimensional grid, which tells us if there is a part or not, and in which direction it has connections.
89-- The parameters x,y,z are the axis of the space station, which iterate to sSSize, the maximal size of the space station.
90-- The griddimension, this word I will use later, means that the distance of a point to the next point is gridDim in the game, so the absolute x-axis is x*gridDim*sSScale,
[9348]91--  and so on for the other dimensions y and z.
[5333]92-- grid[x][y][z][0] contains 0 if there is no part at the position (x,y,z), otherwise 1.
93-- grid[x][y][z][1] contains 0 if there is no connection from (x,y,z) in x-direction, "+" if there is one in the positive x-direction,
[9348]94--  "-" if there is one in the negative x-direction, "+-" if there are in both x-directions.
[5333]95-- grid[x][y][z][2] contains 0 if there is no connection from (x,y,z) in y-direction, "+" if there is one in the positive y-direction,
[9348]96--  "-" if there is one in the negative y-direction, "+-" if there are in both y-directions.
[5333]97-- grid[x][y][z][3] contains 0 if there is no connection from (x,y,z) in z-direction, "+" if there is one in the positive z-direction,
[9348]98--  "-" if there is one in the negative z-direction, "+-" if there are in both z-directions.

118-- This creates an array which stores all the parts, it's size is depending on the global values pDim and sSParts.
119-- The first parameter i, tells us how many parts fit into the array, so it iterates from 1 to sSParts, each part has his own value i.
120-- The second, third and fourth parameters are the relative coordinates of the part, you have to start at (0,0,0) and be sure you fill the array into the right direction.
[9348]121--  A short example: your part is 2 griddimensions long and you place it in the game, that the relative coordinate point is at (0,0,0) and the part lies in the positive
122--  z-axis, then you have to use the coordinate point (0,0,1).
[5333]123-- The fifth parameter is an array with size 4, at index=0, you have to set 1 if your part covers the gridpoint at (x,y,z), otherwise 0.
[9348]124--  At index=1,2,3 you define the possible connection directions (1 for x, 2 for y and 3 for z), be sure to use the notation from above (0, "+-", "+", "-").

160-- Here you can add a part to the space station, there are some examples here and how to describe your part is written above in the commentary.
161
162-- The part must be inserted so, that the center of reference is at position (0,0,0).
163-- At position bodyParts[i][0][0][0][4] you have to put the mesh name of your part.
164-- At bodyParts[i][0][0][0][5] you can rotate your part, with pitch=angle, yaw=angle or roll=angle (x,y or z). Positive angle means in screw direction.
165-- At bodyParts[i][0][0][0][6] you have another possibility to rotate your part in a different way, e.g. for left and right side parts.
166-- At bodyParts[i][0][0][0][7] you have a third possibility to rotate your part, e.g. connection parts must be rotated into 3 different ways.
167-- At bodyParts[i][0][0][0][8] you can rotate your part around his own axis, with rotationaxis="x,y,z" rotationrate=number.
168-- At bodyParts[i][0][0][0][9] you can attach something to your model, e.g. <ParticleEmitter .../>.
