What are Waypoints?
Waypoints are locations that a mob will move to when it is in its default wandering mode (just walking around without a target to attack).
Multiple waypoints can be chained together so that when a mob reaches a waypoint it will then begin moving toward the next waypoint in the chain.
You would do this if you wanted mobs to follow a specified path.
You add waypoints by placing waypoint 'runes' on the ground in the world. A common way of doing this is with the command
[add waypoint
to create a waypoint rune and place it in the world. Keep adding as many as you would like to have in your chain of waypoints.
Then to link them together just double click each rune and then target the next one in the chain.
Setting spawns to follow waypoints?
To spawn things that will follow those waypoints, just set the Waypoint property on the spawner to point to the starting waypoint (set the property on the spawner and target the waypoint rune).
When you save xmlspawners that have a Waypoint setting, either the name (if the waypoint has been named) or the Serial id of the waypoint will also be saved so that if you reload the spawner the waypoint setting will be restored.
