If I have a list with 1 or more objects in it how do I determine how many objects are in it?

The length of a list is stored in the list.len variable.

if(list.len) //<-- I know this asks if the list has any length


But how do I ask if the list has a length of 2 or 3?

if(list.len=2||3)


Maybe this, I'm not too sure.

Just as he said: The list's length is stored in the 'len' variable. As such, it will be equal to how many items are in the list:


var/list/myList1=list("one","two","three")
    // myList1.len would be 3

var/list/myList2=list("one","two","three","four","five")
    // myList2.len would be 5

Almost. You need to be using the == operator here. Also, you must give another statement to be evaluated after the || operator.

if(myList.len==2 || myList.len==3)
    // Stuff here.
