Post subject:  drawing ovals with arrays
Is it possible to make an array and make it so that each variable can draw an oval that I would be able to move across the screen?

I don't quite get what you're saying...

...but you could do this:

code:

type coord:
record
x : int
y : int
end record

var test : array 1..20 of coord


Then, you'd just use some maths to assign the coordinates for each variable, then draw an oval using each ref-point.

Or you could use 1 oval, and just calculate its co-ordinates at each point of the screen.
You'll need cosd and sind for that.

i don't follow what u mean?? do u mean 1 oval mobin across teh screen and its variables in an array?? or multiple ovals??

i would just make a decresing loop of hte y coordinate ,and a decreasing loop for the x coordinate , that way it would move donw the screen , what is the bigger picture for this program , so i know what im trying to make , id liketo help but i dont understand the situation

sry.. i didnt explain it well. i just started to use arrays recently. I am trying to make a small explosion. I need a whole bunch of dots to go out in different directions at the same time.

Don't try understand his code...it's unbelieveable.

I tell ya, that guy is freakin insane!

In a really nice way though... Wink

im trying to make my own but its not workin at all.. heres the code, someone look at it and tell me what is wrong with it

code:
View.Set ("graphics:max;max, nobuttonbar")
randomize
var x:array 1..10 of int
var y:array 1..10 of int
var em:int

for exn:1..10
x(exn):=393
y(exn):=262
end for

 
for exn:1..10
for expl:1..100

randint(em,-1,1)
randint(em2,-1,1)

drawdot (x(exn), y(exn), 16)
delay(10)
drawdot (x(exn), y(exn), 0)
x(exn):=x(exn)+em
y(exn):=y(exn)+em
end for
end for
