Question about tables?
I have this script where I choose a random number, then transfer it to a letter using this table. Should I be using the [1] = 'A' or the 'N'?
01 | _G.alphabet = { |
02 | [1] = 'A', |
03 | [2] = 'B', |
04 | [3] = 'C', |
05 | [4] = 'D', |
06 | [5] = 'E', |
07 | [6] = 'F', |
08 | [7] = 'G', |
09 | [8] = 'H', |
10 | [9] = 'I', |
11 | [10] = 'J', |
12 | [11] = 'K', |
13 | [12] = 'L', |
14 | [13] = 'M', |
15 | 'N', |

I would go with the N and below since you're just going after random letters. Unless a index value is defined like with A-M, then the index value will go from 1 to 2 to 3, etc.
How you can have the table spit out a random letter would be a table like below;
1 | _G.alphabet = {'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z'} |
And then with that, you can use the math.random() function to randomly select the letter in this table, unless the table has pre-defined index values (["Test"] = true).
To have it randomly select a value you can do;
1 | --The script should go TableNameHere[Within The Brackets Is Where The Index Value Goes] |
2 | --And # can help with tables to find out how many values are in the list. |
3 | print(_G.alphabet[math.random(1,#_G.alphabet)]) |
So I'll break this down a little bit more
1 | print() --How else will you know the letter |
2 | print(_G.alphabet) --Start to have it look at the table. |
3 | print(_G.alphabet[]) --Make sure you have brackets for index value. |
4 | print(_G.alphabet[math.random()]) --Get math.random ready to random select. |
5 | print(_G.alphabet[math.random(1, #_G.alphabet)]) --1 is the first value of the index, # will get the number of values in the table |
So it should print out A or C or G or T or M or Z etc...
