Is there any advantages/disadvantages of using arrays over user-defined type?

Any performance difference?

They perform different uses.

A type is for keeping related information together. For example, all the characteristics of a monster (energy, attack power, defence ability, speed etc)
An array is for keeping collections of entities with the same attributes. For example, a series of integer numbers or an army of monsters.

By putting types into arrays, you have an easy way to keep collections of well-defined entities.

How do I put types into arrays?

Can DBPro put types into arrays too?

Can't we just make an array with 2 dimensions for example, the first dimension being monster numbers, and the seconds dimension being the attributes?
DIM MonsterAttribute[100,4]
MonsterAttribute[1,1] = attack power
MonsterAttribute[1,2] = defence
MonsterAttribute[1,3] = energy
MonsterAttribute[1,4] = speed

So far I've preferred to use arrays instead of type, because it can be saved and all.

What would the advantage of types be, other than it's convenient naming?

A simple example...what if you want to store a name (string), health (integer) and speed (float) for 100 bad guys?

Take a look at this tutorial that I wrote for DBPro in...April 2005! The principle is identical.

Thanks for the turorial.

I see, we can have different types of values easily by using types.

So far, I've only made several arrays for different types of values...


Is there an easy way to 'store' the values in types, for example, for saving you game, and loading it back later? (Without saving it to an array or datafile)

I don't think this is possible. You need to write your own serialisation routine to save it out and read it back in again.
