Okay...
Here is the best way to "start" using OgreFollow.
Going to use the following as examples:
You have a tank (person you want people following), and you have the rest of your group (persons whom you want to follow the tank).
So..
Tank = tank
Group = everyone except the tank
On the group, make sure MoveToArea is checked, and probably "Auto Follow Mode" (I say probably because I'm not at home to check).
Now, hit the OFol-Dft (OgreFollow - Default options) button. You can do this out of combat just to test it. People will follow you about 8 meters behind (that is the default). If that is too close, press the OFol-++, it adds 2 meters. So they would now follow 10 meters behind. Press it again, they follow 12 meters behind.
If you get too far away, press OFol---, it subtracts 2 meters.
The only time OFol is turned off, is in these 2 conditions:
When your target is cleared (remember, if you are targeting your tank and killing their implied target, your "target" isn't cleared. I'm going to change this for the defaults at some stage).
Second: When you have move into melee range/move behind/move in front and have a valid kill target. When that valid kill target is no more (such as it died), you will return to following.
With OFol, it doesn't matter if you have face mob in combat checked etc.
It is a little "clunky" because all it does, is if you are > 8 meters, move forward until you are less than 8 meters. There is no "slow down and move forward for a meter or 2" like in-game follow.
Campspot - Make sure you have MoveToArea checked.
If you press "Cmpspt-Dft" (or however it is spelled), this means your group is locked to the area they are currently standing. They will never move. If you press Jst-In (Joust in), everyone is free to move (if you have move into melee range, they will, if you don't have it checked, they won't move, but you could manually move them).
Pressing Jst-Out (Joust out), will cause your group to stop any movement they are doing (such as move into melee range) and return to their campspot area.
Personally, I use the "CS-JO-JI". This sets a bunch of default options.
It sets campspot for everyone at their current position.
It tells mages and priests, you are never allowed to move.
It tells fights and scouts, you can joust in (allowing move into melee range).
Then, when you need your fighters/scouts out, you press "Jst-out" and they will go to their campspot. You press "Jst-In" and they will return to moving into melee range.
"Lets go" always clears campspot.
