These routines are working fine now.
I'm open to suggestions and updates/tests.
It uses the extended units structure (IUnit). Header and libraries available for download
here (read also
this post).
Please do not distribute any altered code, but run it by me first.#include "RepairAI.h"
#include "OP2extra.h"
#include "IUnit.h" // extended units
int Repairs[512][7]; // contains UnitIDs of convecs repairing those buildings
// space for 512 buildings for each player
bool RepairGPs;
/*
SetupRepairAI(bool FixGPs)
Call SetupRepairAI to set up the repair-AI.
It will create a timer, and check ALL buildings for possible damage.
(if FixGPs is set to false, GPs are NOT fixed. This was added because damaged GPs
can explode when the convec is right next to it)

DoCheck(int playernum)
This is the main routine for checking damages. It should be called for every AI player.
The routine stores what convecs already have repairing orders, so it does not give them
any new orders, overwriting the old ones. Vice versa: if the building is not yet 100%
repaired before the next time this routine is called, it will not send another convec
in to repair it.
It repairs any buildings that have more than 100 points damage to them, excluding
buildings that are currently being constructed or dismantled. This DOES include buildings
that are currently under attack.
