Moving Units
Okay.
If you want to order the unit to move, you don't need JASS but can do it with GUI, like this:
Unit- Order (Your Unit) to (Move to) center of (Wherever You Want).
If you want to move your unit Instantly, meaning blink-like, you can also use GUI for it. It will look like this:
Unit- Move (Your Unit) instantly to (Wherever You Want)
(Also, you can choose to make them move there facing a certain angle or region, but that's up to you. Just so you know, it's a completely different action.)
(That's how it should look like. Note that These spaces are replaceable by your choice.)
I hope that answered your question.
