NPC check

[micheel15]

I am trying to make a script that when I get close to an NPC it does a Fullcheck if the NPC is on the screen if the NPC is not it returns some points before in a Label, but when arriving at FullCheck instead of returning to the previous label or forward it back to the beginning of the script

the script is like this

BBOT
Cavebot.Waypoint=@M:422127801433691033291358253292
Point (32681 31692 7)
