[SOLVED] Modifying random child object

[mrbloomfield]

Hello,

I have a parent_object. I would like to create a button which - after clicking on it - randomly selects one of the "children" and change it into different instance. How can I code that?

It depends on a couple things. If it can be any child of the object then it wouldn't be the most efficient but the easiest would be:

///select_random_child(object)

var _list = ds_list_create();
with (argument0) {
    ds_list_add(_list, id);
}
ds_list_shuffle(_list);
var _random_child_id = ds_list_find_value(_list, 0);
ds_list_destroy(_list);
return _random_child_id;

If I remember correct:

target = instance_find(obj, irandom(instance_number(obj)));

with(target){
    instance_create(x,y,different_object);
    instance_destroy();
}

EDIT: I forgot the last part to switch object

Awesome. Thank you everyone.
