Walker Guide
Click on the wand at the top left, go into Looter
Click on the + next to Default, and give your new path a name. (Generally I name it the spawn name for easy reference)
You can then click on auto learn at the bottom right and run your rotation. Generally I do a big circle, but make sure to go from the start of your path, back to the start when you are done. Not doing so will cause the bot to break.
Make sure to set the Walker Timeout: Value. I would set this anywhere from 1-3 seconds and you do this with the slider next to the bar. This will cause the walker to attempt to go to the next point. Usually helps get it going if the bot becomes stuck.
In conjunction with Walker, I would also select the settings below in Targeting.
Auto Learn will not add going up/down steps. So make sure to add a Waypoint type: Node next to the stair, and then another one with the Walk:North, East, Etc after it to force the bot up and down stairs. You need to add this every time you go up, and every time you go down. Example picture below of walking the bot to the point before the stairs, and then up.
My bot keeps breaking, keeps spamming no way whats going on? A: Most likely you either lagged and went too far of a distance during auto learn. Or auto learn skipped a step and made 1 spot unreachable. Just add a waypoint in between the spot you are stuck on and the next one to fix this.
Make use of the Stand and Lure waypoint types. Lure will cause you to keep walking to that node even if mobs are on you, and stand will go to that node and then wait depending on the number of targets you have set in targeting.
You may also want to set your Targeting to stand still. This will force your bot to walk along the path, and avoid any situations where you chase a mob out of your waypoint range and break it.
You can set your Target Count in Targeting to keep your bot walking until you hit the maximum amount of mobs you want to tank. For example, I set mine to 3.
