How do I call functions for objects in an array list?
Hello, I want to know how to call functions for objects in array lists. I have tried several methods but can't figure it out. My code is long and has a lot of unrelated parts so I didn't include it here, but if you think it would be helpful to see just ask.

Use List::get() method in order to access the indexed stored object 1st:

List::get() should just work if you had declared the generics datatype of the container:
https://Processing.org/reference/ArrayList.html
Now that you've got the desired indexed element object outta the container, you're free to use the dot
.operator to access any members from the object:https://Processing.org/reference/dot.html
