Question

I made shoot em up like game.But I have only one ememy which fallows me on screen.But I want to make lots of enemys like each 10 second they will across on screen together 5 or 10 enemys.

 ArrayList<Enemies> enemy = new ArrayList<Enemies>();

 for (Enemies e : enemy) {

        e.draw(g);
    }

is it good creating array list and then showing on screen?
And Do I have to make some planing movements thoose enemies in my code ? I want that they vill appear not on same pozition.Like First 5 enemies will come top of screen then the other 5 or 10 enemies will come from left side.. so on.What is best solution for this?

And I have problem where to fullfiel this array like

enemy.add(new Enemies(750,60)) 

But this doesnt work ((

Answer 1

Use for example a random property and onScreen property. And set them when you show them on the screen.
