Legacy GM Turning Multiple Objects *SOLVED*

[Odolwa]

I have an object with separate hitbox objects matching its movement. I want to make a shorthand for the code when manipulating the 'image_angle' of all of these at once. At present I have it as follows:

image_angle += 1 //The main object
obj_a.image_angle += 1 //The hitbox objects a, b & c
obj_b.image_angle += 1
obj_c.image_angle += 1

If I wanted to reduce all of that to a single line variable do I use an array? I've tried writing the following, but I get an error so I must be doing it wrong:

var array[3] = obj_a.id, obj_b.id, obj_c.id

Can anyone help? Thanks.

You should use this code to initialize the array

var array;
array[0] = obj_a;
array[1] = obj_b;
// ... and so on

Ok, so I created the array as you described and then tried manipulating the 'image_angle' as follows:

array.image_angle = image_angle //Image angles of all hitbox objects in the array will match the image angle of the main object they are attached to

However, an error is thrown which says this is an illegal use of arrays. How should I write the code then, to get the desired effect?

for (var i = array_length_1d(array)-1; i >= 0; i--) {
  (array[i]).image_angle += 1;
}

Great! Thank you.
