Question re AI Modding

[Q]

JLS I have seen different AI building priorities:

First priority are facilities if there is space left on the colony. The facilities are chosen according to the colony type and the AI facility construction file.
Second priority is the AI vehicle construction file. Of course you can have units in this file too.
Last priority is the AI unit construction file.

For homeworlds the AI goes directly to the vehicle construction file because homeworlds are full with facilities at the beginning of the game. However for new colonies facilities are built first, which makes them very vulnerable. A human player would usually build first one or two weapon platforms if the colony is at risk for enemy attacks. As far as I have seen it, the AI does not do that.
