Not a lot different from normal variables really, except that you *have* to declare them.

type MyType
a as integer
b as float
c as string
endtype

` Declare 2 variables
V1 as MyType
V2 as MyType

` Fill out the first
V1.a=1
V1.b=1.2
V1.c="Hello"

` Fill out the second
V2.a=4
V2.b=99.99
V2.c="Goodbye"

` Subtract their values in the normal way - all arithmetic is identical to standard variables
print V1.a + V2.a

Just like you declair a normal varable as a type you can do it with arrays as well


You can also have types within types

As of just recently i discovered that DBPro could use types, which in my opinion is the most useful thing that a program can have... but as of my attempts there seems to be no support of arrags within types.
eg.

Type Model
Dim Equipment(4) As String
EndType

Has any one got arrays to work in types, either through work arround or a dll function, any help would be much appreciated.

w00t -what does it mean?

you can array the type instance, not a var within the type - would be very useful however.

also, if you think types are cool you should see Classes.

@the_winch if I do
Type Monster
sfdf
endtype

Raeckon as Monster
sfdf
endtype

could I do
M as Monster
and still control the sub types of the types?

` create a UDT
type monsterData
name$ as string
hp as integer
ID as integer
endType

` create an array of monsters
dim monster(10) as monsterData

` describe the first monster
monster(1).name$ = "Scarecrow"
monster(1).hp = 10
monster(1).ID = scarecrowObject :` a previously loaded model ID

remStart
A model already had XYZ position and rotation so we don't need to include that in the monsterData UDT, just the object ID the monster uses.
remEnd

How about that for a starter?

the first monster would be monster(0)

if you have "M as Monster" in your code then you will have 1 monster with the attributes of the type. If you have "Dim M(9) as Monster" in your code then you'll have 10 monsters, all with the attributes of the base type - BUT - it's up to you to know which moster you are dealing with by keeping track of the INDEX value (num) of the arrayed monsters.

if you correlate the object numbers of the monsters to the exact array index of that monster then you could be "notified" of which monster was attacked by the collision value returned.

Yes, CR. I know about DB's N+1 array behavior and base zero. Since Oneka is just starting out, I didn't want to go into that right away.


Oneka, we're creating these examples on the fly. I doubt there is any code to show unless someone sits down and writes it for you.

zirch, I know you know I am just of the mindset of "teach it as it is, straight away" Instead of learning a bad habit that has to be unlearned later.


Oneka, I have no code example
