Can someone help me to understand how to use Linked List with a practical example, please? I am using this one: [vJASS] - LinkedList Modules
I have a spell "hook", and I want to add all the links to the list. Then, I want to add new links if the gap between the caster/target and the link is more than x and delete them when the gap is smaller than y. I understand how to do it with arrays, but not with the list. Here is my hook:
