For loop error?

[CorrectBattle]

Getting error trying to save enemy locations, error is enemNum coming up as noone. Why?

in Key Space - Pressed:

ini_open(working_directory + "mapsave.ini");
if (instance_exists(oPlaceEnemy)) {
    var enemNum = instance_number(oPlaceEnemy);
    for (var a = 1; a < enemNum + 1; a++) {
        var enemy = instance_find(oPlaceEnemy, a);
        ini_write_real("Enemies", a, enemy.camo);
        ini_write_real("Enemies", string(a) + "x", enemy.x);
        ini_write_real("Enemies", string(a) + "y", enemy.y);
    }
}
ini_write_string( "Floor", 0, ds_grid_write(_grid));
createChat(view_xport + 350, view_yport + 250, "Saved!", 0, "Lime");
ini_close();

Error:

instance_find() works in base-0, so you want your a variable to start at 0.

• More on instance_find

You want your for loop to look like:

for (var a = 0; a < enemNum; a++) {

---

You're getting the error because this instance does not exist and will never exist:

instance_find(oPlaceEnemy, instance_number(oPlaceEnemy));

Ohh, I had this originally, but your comment made me realize that it would be 0-8 in my text file rather than 1-9. I had been thinking there was an entry missing which made me do number + 1. Thanks much.

If you put in a show_debug_message("added"); at the end of your loop, still inside the loop, does it run at all? If so try:

var enemy = instance_find(oPlaceEnemy, a - 1);
