Four dimensional array

[Konidias]

Does it exist? Is there an extension that can do this?

You can do this easily for example with the Named Variable object.

So you can define variable names like 1-1-23-8 for a specific position (in this case 4-dimensional) as string or value.
If you want to split the variable names again easily use the String Tokenizer object and use "-" as delimiter.
So you can add even more dimensions if you want.

Just use a 1-dimensional array to simulate a 4d array - the maths for converting between 1-d index and n-d array coordinates is not too difficult:

w = i mod dimw
x = i mod (dimw*dimx*dimy) mod (dimw*dimx) / dimw
y = i mod (dimw*dimx*dimy) / (dimw*dimx)
z = i / (dimw*dimx*dimy)

i = (z * dimw*dimx*dimy) + (y * dimw*dimx) + (x * dimw) + w

There's that, I guess. Also the Dynamic Array object supports up to 10D without fancy multiplying dimensions and stuff.

Another question... Which would be quicker, loading and writing/reading to many different small array files quickly, or loading and writing/reading from a giant one?

I'm going to guess the former, but I would love to hear some reasoning. I might not need a 4d array at all, I might just need to store a lot of small arrays in their own files.

I suppose another solution is to use a new array object for every iteration of 4th dimension you wanted to use...

this is kinda troubling for me since I really need a 4-dimension array for my game and the Dynamic Array extension isn't compatible with most exporters

the converting 1d to 4d seems really complicated to me

sigh lol

realized I didn't need 4-dimension array after all. learned a lot. love mmf!
