Multi-Dimensional Arrays
To create an array with more than one dimension, you can specify indexes seperated by commas:
Local int_array1 : Int[4,4] 'create a 4x4 array
Local int_array2 : Int[3,3,3] 'create a 3x3x3 array
You can then refer to them like so:
int_array1[0,0] = 100
int_array2[2,1,0] = 1000
