Using arrays to create more then one same kind of  objects

-----------------------------------

Hello every one. I am a nwebie programmer this my first time attempting to make a game. I neede help with making bullets for my ship. I know i am suppose to use array but dont know how to. I want to creat 20 bullets with same size. one of them is fired every time i hit space bar.

Well there is actually many ways to do this;

for each bullet you need an x and y im supposing, cause you didn't give enough information.

so you could create 2 arrays

var bullet_x:array 1..20 of int
var bullet_y:array 1..20 of int

or you could create a new type, and make an array of it.
type bullet :
      record
           x:int
           y:int
      end record

var bullets:array 1..20 of bullet

both have their own learning curves to them, expessially the second one, im supposing you are almost finished and this is for class, so if you never did the second way; i would recommend doing the first way to save you some time.

If you plan on adding more properties (like damage, size, and speed) to the bullets, then use the array of records.

i just made a sample program using 2 array. I was wondering that how can i chek that first bullet is = 600. I would like you to inform me if i am on right track..

It would be good if there wouldbe some more examples

her is the code:

var x: array 1..20 of int
var y: array 1..20 of int

var count:= 0

for i: 1..20
delay(1000)
x(i):= 10
y(i):= 10
count:= count + 10
Draw.Oval(x(i) ,y(i) ,10,10,1)

for k: 1..20 

delay(100)
x(k):= x(i) + 10
%y(k):= x(i) + 10
Draw.Oval(x(i) ,y(i) ,10,10,1)
if x(1) = 600 then


exit
end if

end loop
end for
end for
