For my dragon adventure game, i need to build a ‘maze’. The NetLogo screen itself is an ok size, but if i want playable characters suitable for a video game, i need to use more space.<\/p>\n\n\n\n

Firstly, i designed my simple maze on pen and paper.<\/p>\n\n\n\n

\"\"
the initial maze design – a 4×4 grid<\/figcaption><\/figure>\n\n\n\n

As you can see I started with a 4×4 grid counting from 1, but the NetLogo array function counts from 0, so i redid the map starting from 0. This becomes significant when building the array.<\/p>\n\n\n\n

\"\"
array 1, counting from 1 and slightly unordered, array , more sequential and from 0<\/figcaption><\/figure>\n\n\n\n

So having completed the array for the maze and the interconnecting rooms, I explored how to code this in NetLogo.<\/p>\n\n\n\n

Firstly, I found some pseudo code, this time based on python as I have programming experience of it<\/p>\n\n\n\n

;map = {'corridor':['room1','room2'],'room1':['corridor'],'room2':['corridor'] - python method<\/code><\/pre>\n\n\n\n
So in the python, it defines two rooms and corridor, with how they are connected. This is great for a text based adventure, i want to keep it simpler and not really name the rooms, just from my physical map know which rooms are, so reduced that to numbers.<\/p>\n\n\n\n
I started with following the array example from the NetLogo dictionary, adjusting for the amount of rooms i needed (16).<\/p>\n\n\n\n
let a array:from-list n-values 16 [0] ; init array a with 16 values of 0<\/code><\/pre>\n\n\n\n
So my room ‘0’ connects to room ‘1’, and room ‘1’ connects to ‘0, 5, 2’<\/p>\n\n\n\n
  array:set a 0 \"1\"\n  array:set a 1 \"0,5,2\"\n<\/code><\/pre>\n\n\n\n
As I am testing, i want to see the value of the array in the console as well.<\/p>\n\n\n\n
print a<\/code><\/pre>\n\n\n\n
To make this work in NetLogo i need to create the ‘setup’ button and assign to a routine, so i create the ‘setup’ button from the ‘add’ item menu, and give it the routine ‘setup’<\/p>\n\n\n\n
\"\"
add the setup button<\/figcaption><\/figure>\n\n\n\n
I then wrap the array creation in a the standard function, not forgetting to add the array extension.<\/p>\n\n\n\n
extensions [array]\n\nto setup\n  let a array:from-list n-values 16 [0] ; init array a with 16 values of 0\n  array:set a 0 \"1\"\n  array:set a 1 \"0,5,2\"\n  print a\nend\n<\/code><\/pre>\n\n\n\n
I can then run the setup procedure, which will output the array<\/p>\n\n\n\n
\"\"
values in array represent connections between room<\/figcaption><\/figure>\n\n\n\n
So I can see that my array is getting populated, i will be able to use the values in an index to draw the relevant rooms.<\/p>\n\n\n\n
The completed array<\/p>\n\n\n\n
extensions [array]\n\nto setup\n  let dungeon array:from-list n-values 16 [0] ; init array a with 16 values of 0\n  ; use this line to copy and paste from \n  ; array:set dungeon n \"\"\n  array:set dungeon 0 \"1\"\n  array:set dungeon 1 \"0,5,2\"\n  array:set dungeon 2 \"1,3\"\n  array:set dungeon 3 \"2\"\n  array:set dungeon 4 \"8\"\n  array:set dungeon 5 \"1,6\"\n  array:set dungeon 6 \"5,10,7\"\n  array:set dungeon 7 \"6,11\"\n  array:set dungeon 8 \"4,9\"\n  array:set dungeon 9 \"8\"\n  array:set dungeon 10 \"6\"\n  array:set dungeon 11 \"7,13\"\n  array:set dungeon 12 \"13\"\n  array:set dungeon 13 \"12,14\"\n  array:set dungeon 14 \"13,15\"\n  array:set dungeon 15 \"11,14\"\n  print dungeon\nend<\/code><\/pre>\n\n\n\n
Confirmation output<\/p>\n\n\n\n
\"\"
this was helpful as i could spot the typo on 11.14 <\/figcaption><\/figure>\n\n\n\n
I spotted I had already made a typo on room 15, so I corrected that from 11.14 to 11,15 and my ‘dungeon’ map array was complete !<\/p>\n","protected":false},"excerpt":{"rendered":"
