1. Re: How can I work with a user type arra
Your cell/item tuple can be represented by the sequence:
{ cell, item }
Data types in sequences do not have to be declared. You could define a
prototype (default) your type as:
constant myType = { 0, 0 }. -- default item
constant CELL = 1, -- index to first value
ITEM = 2. -- index to second value
You can use 'myType' like this:
sequence x -- declare the variable
x = myType -- assign it to your data structure
x[CELL] = 22 -- same as x[1] = 22
x[ITEM] = 33 -- same as x[2] = 33
But I digress. You can then create a 2D array using the repeat() command:
global sequence mapVar -- this will be your array
mapVar = repeat( myType, 100 ) -- 1 row = 100 cols of myType
mapVar = repeat( mapVar, 100 ) -- matrix = 100 rows of cols
More typically, you can embed the repeat(), like:
-- more typical; though not very readable IMHO.
mapVar = repeat( repeat( myType, 100 ), 100 )
and even hard code myType:
-- even more typical. bad style, though, IMHO.
mapVar = repeat( repeat( {0,0}, 100 ), 100 )
Once the array is created, you can then assign values like this:
mapVar[2][3][CELL] = 3 -- row 3, col 2, index 1 of myType
mapVar[2][3][ITEM] = 4 -- row 3, col 2, index 2 of myType
Hope this helps.
