Well this may not work but it's still a thing you must learn.
I'll explain for you. The Group you're using is leaking, i supose you know what leaks is. Otherwise go
here and try to learn everything about it, cuz leaks, in massive producing, is really dangerous. It causes bugs, crashes, laggs, etc...
So to avoid that you can use a BJ, with that i mean this action below
-
Custom script: set bj_wantDestroyGroup = true
BJ´s are, and will always be, really slow. With that i mean that when the BJ is "called", it will take some time to get the 'thing' you want started. And that's why you also should try to avoid BJ´s, but in this case, it doesn't matter.
You'll see that when you've pasted this into the Trigger, the effect will be much smoother, in the length.
And also, I'm going to look some further into this thread. Then i can try to solve the problem you've got here.
The things the other guys saying here, that it should be
(Picked Unit) instead of
(Matching Unit), is false. You've done the whole correct in that Condition. But as i said, i'll look some furhter into this.
EDIT:
Well now i've solved you'r problem. So, now if you go into the
Trigger Editor and go to the
Trigger i made called
Zombie Walk, then you can see something that not will be right, here they are (They are there because i don't having you'r real map. Well anyways i'm gonna tell you what you MUST change when you import it into you'r map, well change this following:
From
-
Unit Group - Pick every unit in (Units owned by Player 1 (Red) matching ((Unit-type of (Matching unit)) Equal to Footman)) and do (Actions)
-
Loop - Actions
To
-
Unit Group - Pick every unit in (Units owned by Player 1 (Red) matching ((Unit-type of (Matching unit)) Equal to Zombie)) and do (Actions)
-
Loop - Actions
And also this:
From
-
Set Temp_Loc = (Position of (Random unit from (Units in (Playable map area) matching (((Owner of (Matching unit)) slot status) Equal to Is unused))))
To
-
Set Temp_Loc = (Position of (Random unit from (Units in (Playable map area) matching (((Owner of (Matching unit)) slot status) Equal to Is playing))))
And here's the
TEST MAP 
View attachment Zombie Move.w3x
Zombie Move
Events
Time - Every 2.00 seconds of game time
Conditions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
Unit - Order (Picked unit) to Attack-Move To (Position of (Random unit from (Units in (Playable map area) matching (((Owner of (Matching unit)) slot status) Equal to Is playing))))
I don't know what was the problem with my trigger (I midified it after the question, I tryed to use some custom value thing, but didn't work...)
