well hell lol
Intervals are in seconds(ish). Duration's are in game hours.
(Please keep in mind I haven't fully tested everything out in this)
If you set up the wandering horde into waves like:
Code:
<spawn group="[insert your wandering horde group here]" num="3" maxAlive="64" interval="15"/><spawn group="[insert your wandering horde group here]" num="2" maxAlive="64"/>
In this example:
It pulls 3 zombies from the first group (wave 1) and spawns them. After 15 seconds, it will spawn 2 zombies from that 2nd group (wave 2).
^Tested and works^
From past discussions: I've been told that a maximum of only 3-4 wandering hordes can be called in a 24hr game day. That's 1-3 (or 4) wandering hordes at random times of the game day (something like that)
Theoretically: You should be able to make 1 long wandering horde, but broken up into how many "waves" it spawns, throughout a whole game day using the intervals.
Only thing I have left to do, is test out that 1 wandering horde, but broken up in one game day bit
Hope that answers what you need.
