Heya, d00ds, just some short notes here on guard WP's and GuardedBy triggers.
With the guard waypoint you you can set soldiers / groups in a support mode,
so when some troops are attacked the groups in guard mode will come to support.
When the enemy is defeated & if the guards survive, these guards will return to the
guard WP and stay there. If another attack is coming in, they'll respond...
If you place "guarded by" triggers the troops in the gaurd mode will come regulary to invest
in the area that is in the "guarded by" trigger if there are enemy forces...
Guarded by _x:
This trigger is used with the GUARD waypoint and works as shown in the following example.
First, let's say you have 3 groups (West) that each have reached a GUARD waypoint.
As you've probably seen, that'll make them hang around a bit, and come to the rescue of other nearby units if needed
(after which they'll return to their GUARD location).
Second, put down 2 triggers, and change their type to "Guarded by West". No other changes really needed.
Now the interesting part; two of the groups will move to these triggers' locations, each group to its closest trigger,
to guard it (that is, any nearby friendlies under attack). The third group, the one farthest away from the two
"Guarded by"-triggers, will stay put.
Let's say that one of the two groups at the "Guarded by"-triggers is killed. The two remaining groups will reorganize,
each moving to its closest "Guarded by"-trigger. That could even mean that a group will leave its current location at a
"Guarded by"-trigger to move to another "Guarded by"-trigger, it this group is closest to the second trigger than
any other group.
As you see, "Guarded by"-triggers are a convenient way to set up terrain objectives for AI squads, without having to do
a lot of work. They can also be used to heavily randomize a mission.
AFAIK, "Guarded by"-triggers will never go off, and only their type is important. Everything else seem to be ignored,
unfortunately including radius. Note that you can group a "Guarded by"-trigger with a unit, with expected results.
so!
