i know you can make a trigger to make (any unit) that enter a region to move or what not but is there a way to make a unit spawn at one point and attack-move to another because i cant find a trigger to "pick up" the unit that was created and send it to a point. can anyone help me out?

It is the same thing, just use attack instead of move for the order.

well i know that but i need to make the units(s) that are created at one point to attack-move to another point without entering a region

Does a trigger spawn the units?

use "last created units" to have a reference to the units when you order them directly after they spawned?

i have 5 points. each point spawns a marine every 3 seconds. i need to get these marines to attack-move to another point after they spawn

Use Ahli's suggestion and when a unit spawns (in the same trigger) use an attack order with the unit being the function Last Created unit.
