I'm trying to figure out a way to change all mineral fields on the map to rich mineral fields. Is there some way I can apply a behaviour to all the units on the map of a certain type? I would remove the normal mineral field behaviour and then apply the rich minerals behaviour, Or I could remove all the minerals and place high yield at the position of each but both methods require either a lot of work and triggers or being able to apply something to all units of certain type.
Event: Map init
Local vars: None
Actions: Pick each unit in unit group (entire 'Mineral Cystal's in entire map) and do actions;
Actions: Kill picked unit;
Create unit (High yield minerals) at position of unit (picked unit) facing angle 270;
Will kill all normal minerals and create a high yield version at it's location.
