##### Multidimensional arrays
« on: 2015-Dec-01 »
I'm new to GLB and trying to convert a game I wrote in another Basic dialect which uses a 6 dimensional array as a primary data structure.  It appears there is a 4 dimension limit in GL Basic.  I thought of using Types to address this and was wondering if multidimensional arrays can be handled as variables in a Type, and what the limits are regarding associating chains of variables with Types.  I'm a complete novice so if someone can point me in the right direction to learn about this (other than just trial and error) I'd appreciate it.

Multidimensional arrays? You could switch to C inline code to use them as such. Otherwise, you can use a monodimensional array, and compute which cell/address you want to access. It's the same... remember that all the memory is linear, and accessed like that in a linear way, the data addresses.
Example: GLOBAL v%[] // confusing, I know.   DIM v%[10][20][30][40]
"v[w][X][y][z]" is nothing more than v[40*30*20*w + 40*30*X + 40*y + z]     (from memory lane, please check it.)
This way the number of dimensions in unlimited -just the total RAM size is.
