TFaLCoN	Hi, i am working on a Tower Defense map and have some difficulties making a trigger for creeps to walk a specific route by using a crossroad. Events: Unit - A unit enters START Actions: Unit - Order (Entering unit) to Move To (Center of END)

Captain Griffen	Use custom values on each unit to store which spawn point they came from, and then use that to decide which way to order them when they enter each region.

Ok, ik found out howto setup a custom unit value:

Unit: Set custom value of (Last created unit) to 1

But i can't find a condition to check on the unit value when he entered crossroad, only found this :

(Unit-type of (Triggering unit)) Equal to Footman1
(Unit-type of (Triggering unit)) Equal to Footman2
(Unit-type of (Triggering unit)) Equal to Footman3

But not efficient to make a unit for each spawmpoint; if i would do that with 5 spawmpoints x 40 units i have 200 custom units

harshateja	I like the colorful picture . Back on topic, there is a GUI function that is like Get Custom Value of Unit. And, instead of triggering unit, use entering unit. THen use the Get Custom value of Unit on the entering unit and check if its some INTEGER value.

Alevice	[OT]A little tip: Rather than taking a screenshot and uploading it, you can just right click in your trigger name, select copy as text, and paste it within [trigger] tags. ;)
