several falling objects

Hey.
I'm trying to make serveral falling objects in my program. (in y pos).
But when i call meteor(); in void loop it just draws one image.
Some one there who can help me develope the code?.
(This is how far i have got):
//Variables
int speed = 10;
int start = int(random(100,400));
BImage ship, meteorImage1, meteorImage2;
void loop(){
meteor();
}
//meteor code
void meteor(){
int acc = int(random(1,9));
int num = int(random(1,2));
speed = speed+acc;
if (speed < 0) {
speed = height;
}
meteorImage1 = loadImage("meteor"+num+".gif");
image(meteorImage1,start,speed);
println(num); //Why does it allways become 1 ??
}

you are mixing up typecasting to int with round() ... see below.
int(1.999999f) // returns 1
round(1.999999f) // returns 2
so your "int num = int(random(1,2));" does return 2 sometimes, just very rarely ... 
try:
int num = round(random(1,2));
