Multiple variables without calling at startup?

RockyHawk

I need to have many variables (x, y, x1, y1, x2, y2, etc) for the different positions of enemies and if I make a local variable at the start the other parts of the program wouldn't be able to see it because it is a local variable. How can I do that without making the variable local?

Also note that the built-in PVector already contains an x and a y. So you could use an array or ArrayList of PVectors:

PVector[] enemies;
// or:
ArrayList<PVector> enemies;

Or, as @GoToLoop indicated, if you also have other variables for enemies (such as "health" or "speed" et cetera), then you could wrap these in a class:

class Enemy {
  Enemy(){}
  float x;
  float y;
  int health;
  float speed;
}

....and then create an array or an ArrayList of your class objects:

Enemy[] enemies;
// or:
ArrayList<Enemy> enemies;

Ah so instead of a variable I used an array and then I used a for loop to go through all the enemies in the array.
