lua nested tables insert table into another table
ok i have this table :
tbm.offsets = { -- facedir indexed (+1)
{ -- facedir = 0
{ -- first line
{ X = -1, Y = 2, Z = 1 },
{ X = 0, Y = 2, Z = 1 },
{ X = 1, Y = 2, Z = 1 }
},
{ -- second line
{ X = -1, Y = 1, Z = 1 },
{ X = 0, Y = 1, Z = 1 },
{ X = 1, Y = 1, Z = 1 }
},
{ -- third line
{ X = -1, Y = 0, Z = 1 },
{ X = 0, Y = 0, Z = 1 },
{ X = 1, Y = 0, Z = 1 }
},
{ -- forth line
{ X = -1, Y = -1, Z = 1 },
{ X = 0, Y = -1, Z = 1 },
{ X = 1, Y = -1, Z = 1 }
}
},
{ -- facedir = 1
{ -- first line
{ X = 1, Y = 2, Z = -1 },
{ X = 1, Y = 2, Z = 0 },
{ X = 1, Y = 2, Z = 1 }
},
{ -- second line
{ X = 1, Y = 1, Z = -1 },
{ X = 1, Y = 1, Z = 0 },
{ X = 1, Y = 1, Z = 1 }
},
{ -- third line
{ X = 1, Y = 0, Z = -1 },
{ X = 1, Y = 0, Z = 0 },
{ X = 1, Y = 0, Z = 1 }
},
{ -- forth line
{ X = 1, Y = -1, Z = -1 },
{ X = 1, Y = -1, Z = 0 },
{ X = 1, Y = -1, Z = 1 }
}
},
{ -- facedir = 2
{ -- first line
{ X = -1, Y = 2, Z = -1 },
{ X = 0, Y = 2, Z = -1 },
{ X = 1, Y = 2, Z = -1 }
},
{ -- second line
{ X = -1, Y = 1, Z = -1 },
{ X = 0, Y = 1, Z = -1 },
{ X = 1, Y = 1, Z = -1 }
},
{ -- third line
{ X = -1, Y = 0, Z = -1 },
{ X = 0, Y = 0, Z = -1 },
{ X = 1, Y = 0, Z = -1 }
},
{ -- forth line
{ X = -1, Y = -1, Z = -1 },
{ X = 0, Y = -1, Z = -1 },
{ X = 1, Y = -1, Z = -1 }
}
},
{ -- facedir = 3
{ -- first line
{ X = -1, Y = 2, Z = -1 },
{ X = -1, Y = 2, Z = 0 },
{ X = -1, Y = 2, Z = 1 }
},
{ -- second line
{ X = -1, Y = 1, Z = -1 },
{ X = -1, Y = 1, Z = 0 },
{ X = -1, Y = 1, Z = 1 }
},
{ -- third line
{ X = -1, Y = 0, Z = -1 },
{ X = -1, Y = 0, Z = 0 },
{ X = -1, Y = 0, Z = 1 }
},
{ -- forth line

{ X = -1, Y = -1, Z = 0 },
{ X = -1, Y = -1, Z = 1 }
}
}
}
it is a static table in Lua already but i want to make it dynamic, the table lists XYZ cordinates for a number of lines of blocks, i want to be able to adjust the coordinates table based on user input, for example if they want a grid of 20 blocks 3 lines high how would i assemble the table from within a for loop? each block has an xyz and is in a row, each row is part of a block and the coordinates depend on which way the direction is facing.
what i have begun to figure out in the last 15 mins it would look something like:
temp = {}
temp1 = {}
temp2 = {}
temp3 = {}
for facedir = 1, 4 do
for block = 1, 5 do
for Line = 1,5 do
for X1 = -5, 5 do
for Y1 = 5,-1 do
for Z1 = 1, 5 do
temp = {X = X1, Y = Y1, Z = Z1}
end
end
end
temp1{ line = temp }
end
temp2{block = temp1}
end
temp3{facedir = temp2}
end
would the above code work? or what is a better/easy solution to implement, this code will be executed repeatedly, sometimes with he same variables sometimes with different variables.

Modified to be syntactically and logically correct the above code looks like this:
local temp3 = {}
for facedir = 1, 4 do
local temp2 = {}
for block = 1, 5 do
local temp1 = {}
for Line = 1,5 do
local temp = {}
for X1 = -5, 5 do
for Y1 = 5,-1,-1 do
for Z1 = 1, 5 do
temp[#temp + 1] = {X = X1, Y = Y1, Z = Z1}
end
end
end
temp1[Line] = temp
end
temp2[block] = temp1
end
temp3[facedir] = temp2
end
For reference tab = {key = value} will create a table, store it in the tab variable with a key of "key" and a value of whatever is in the variable value. If you want to use a variable as the key you need to use the longer tab = {[key] = value} format for the key. The bare word version is simply syntactic sugar for tab = {["key"] = value}.
