What code are you using to spawn? what limitation(s) do you wish to impart?

public void spawns()
{
if(Greenfoot.getRandomNumber (50) < 1)
{
addObject(new Asteroid1(), 599, Greenfoot.getRandomNumber(400));
}
}

This is the code That I'm currently using. By limitations, I want to limit the spawn of the enemy. Ex: Only 30 asteroids in the first wave.

If you want exactly 30 asteriods, change line 3 to this:

for (int i=0; i<30; i++)

If you want a maximum of 30, you can add the line before line 3. (In this case, you should change the 2% you are using to something higher.)

First thing, if you want the value of the limit to be variable, you will need to use a field for its value. As such, you would have this:

// instance field
private int toSpawn = 30; // setting initial value
// the code
public void spawns()
{
    if (toSpawn>0 && Greenfoot.getRandomNumber(50)<1)
    {
        addObject(new Asteroid1(), 599, Greenfoot.getRandomNumber(400));
        toSpawn--; // 
    }
}

You can then use some expression that depends on the wave number to set the number of enemies to produce each wave. Something like:

toSpawn = 25+5*waveNumber;
