Artificial Intelligence (AI)

AIs (Artificial Intelligences) are used to make a unit act upon certain conditions.

For example: New worker is created + Resources is lower than 50 ore => Send worker to closest mineral field.

Trigger References

Basically, what you are searching for is the "Issue Order" action. Keep in mind you can change the Order "type" by clicking the parenthesis. This is very important because you can't find, for example, the Blink ability under the "Order With No Target" order-type.

   Actions
       General - Wait 1.4 Game Time seconds
       Unit - Order (Triggering unit) to (Stalker - Blink targeting (Random point in (Entire map))) (After Existing Orders)

The conditions set in this trigger are to prevent the AI to be applied to players currently playing. Any players leaving will see their unit gotten in charge by the AI trigger.

Please take note that a unit becomes idle only when one of his issue is done. Thus, units that were pre-placed or just created will not be considered as idle since they haven't had any actions ordered to them yet.
