Default Object Position in List - 05-04-2010, 05:23 PM

Is it possible to ask an object it's position in a list? So I can tell what Index to remove from the list.

Drag the list onto the scripting area and you'll have the option to make a "Remove item from position [index] of [name of list]" method. Choose any index you want so the method will be created. Then, drag the list onto the index variable, and one of the options will be "First index of..." Using this, you can look for the first occurrence of a certain object. By combining it with the remove item method, you have a method which scans the list to see where the object is, then removes it accordingly.

I included a world with an example of the code I described.
