Generals Alpha is an OpenRA mod that recreates Command & Conquer: Generals on OpenRA engine as much as possible but using Red Alert and Tiberian Dawn artworks.
I have coded a ConditionPrerequisite and LaysMinefield logic which allowed me to implement this. With ConditionPrerequisite, i also made Radar upgrade per Command Center and also impelented Stealth General's Camo Netting on structures.
Do the mines also respawn over time when destroyed?
Yes.
