Well, a 1-dimensional (1d) array would be like:

DIM array(32)

Making an array with 32 indices

A 2D array would be like:

DIM array(32,32)

An array with 32x32 indices. If you've got any experience with spreadsheets, it's an idea to visualise a 2D array as a spreadsheet - more dimensions in the array might signify 'worksheets', like a 3D array:

DIM array(256,256,10)
Which would be like a spreadsheet with 256x256 cells, and 10 pages.
In Excel terms, cell A1 on worksheet 1 might be array(0,0,0).

Well, let's say your character has 4 weapons, and you want to know how much damage each weapon does.

We make a 2 dimentional array.

CharacterWeaponDamage(10,4)

In the above array, there are 10 characters, EACH has 4 weapon slots.
You can use that array for a variaty of things, like storing weapon DAMAGER, or weapon RELOAD TIME.

for example:

Here we talk about character number 1 (or entity number 1), as you can see the left number on the index represents the number of the entity, and the second number represents the weapon number.
CharacterWeaponTimer(1,1)=500 `weapon 1
CharacterWeaponTimer(1,2)=1000 `weapon 2
CharacterWeaponTimer(1,3)=1500 `weapon 3
CharacterWeaponTimer(1,4)=2000 `weapon 4
So have character 1 which has 4 weapons, each weapon holds a number.
That number represents the damage that specific weapon on that specific character does.

This belongs in the Newcomer's Corner

It is a perilous occupation for TGC to post anything by way of a promise, as the words get etched in indestructable marble for all time.
