a[32] = {}
a[32][20] = {}
a[32][20][20] = 67
Try this

function table.array(v, ...)
local t = {}
if arg[2] then
v = table.array(v,table.unpack(arg,2))
end
for i=1,arg[1] do
t[i]=v
end
return t
end
Will create a three dimensional array with all it's values set to 1.

table={}
function table.array(v, ...)
local t = {}
if arg[2] then
v = table.array(v,table.unpack(arg,2))
end
for i=1,arg[1] do
t[i]=v
end
return t
end
mmpmap = table.array(0,32,20,20)
Btw, table.unpack is just the unpack() function.
Your easiest bet is now to make a triple loop:

function threedarray(v,d1,d2,d3)
local t = {}
for i=1, d1 do
t[i] = {}
for j=1,d2 do
t[i][j] = {}
for k=1,d3 do
t[i][j][k] = v
end
end
end
return t
end
Or atleast something like that should work.

end
return t
I think, this should work.

if type(a[23])=="table") and type(a[23][42])=="table") and type(a[23][42][77])=="table") and a[23][42][77]~=nil then
print("it exists!")
else
print("nope try again!")
end
nope try again
3D arrays are usually very memory intensive. For example, a 3D array of dimensions 23x42x77 requires the allocation 74382 empty cells, each of which takes up 8 bytes on the stack and a proportional amount of memory somewhere else in memory.
If you only need a few points in a large 3D space, try using this scheme:
{point1, point2, point3, ...} where each point is a table containing the x, y, and z coordinate of that point.
Are you saying having a table like...
a[23-42-77]=true
a[33-42-65]=true
etc etc
