[Trigger] Clarifying variables

[Modding-Ivan]

So i was trying to assign a location variable to another location variable also the logic of my trigger was all correct except that i notice is that when i try to reassign the latter variable it takes and removes the value of the former variable. If i may ask are gui variables pointers? Are there any specifics why variables acts like pointers in gui?

Yep, both location variables will point on the same location object. So when you destroy one variables's content, it will be destroyed likewise for the other one. It's not being copy-constructed, if you meant that/maybe have some programming background.

Thanks for the fast reply i was really distraught why my trigger wont work. I just realized it now after all this time.

Not a trait of GUI, all object variables in jass are refs. There is no general copy construction. Imagine you could just copy a unit, some objects are interactive in the game world. With a location it's relatively easy, though, there is a function "Convert coordinates to point" as well as "X of point" and "Y of point".

In the jass world, locations are mostly not required, by the way.
