Random Spawn Location!

Is there a way to make units players send start at random regions?

And whats the best way to script units to keep attack a unit (thats allrdy in a unit group)

1) don't understand what you want...sry

2) periodically loop through the group and issue "attack"-order

OR

register all order-events (ISSUE_ORDER, ISSUE_POINT_ORDER, ISSUE_TARGET_ORDER) and check if the ordered unit is within your group, if it is and the order is different from "attack" then disable the order-trigger, pause the unit, issue "stop", unpause it, issue "attack", enable the order-trigger. this method requires to issue "attack" when an unit is added to the group.

i thing second way is more efficient, but also more difficult to code...

Cool thanks that helped alot!!

Ok what i meant by the first one is, i have a region, where the units enter (like creep sends), then i want those units that enter the region to spawn in random other regions?

use unit enters region event and an array with all possible random locations/regions
everytime an units enter the region, move it instantly to the location/region at a random place in the array. use a random integer form <index of first location/region> to <index of last location/region> as index to determine the location/region where you wanna move your unit

How do i add regions to the array?

You need to do it in a trigger that runs on map initialization: just use the "set variable" action.

Will this work on multipale regions?

yes, you need a region-array and an integer to count how many regions you have.
then simply populate the array and set the count-integer to the maximal used index of your array.
