It seems like the mission Bonemender (python) is bugged.
When ever I am trying to cast regen on Chandra it just says “ArgumentError: Target is null. Is there always a target to attack? (Use if?)”. I have spent like 2-3 hours in just trying to find the correct code for this but then I gave up and look up online and found several people who have used the exact same code as I am but they do succeed this mission. I also see a post on youtube that another person tried the same and cannot get though this mission of the same error.
The code itself
# Heal allied soldiers to survive the siege. while True: if hero.canCast("regen"): bernardDistance = hero.distanceTo("Bernard") if bernardDistance < 10: # "Bernard" needs regeneration! hero.cast("regen", "Bernard") # Use "if" and "distanceTo" to regenerate "Chandra" # if she is closer than 10 meters away. chandraDistance = hero.distanceTo("Chandra") * List item if chandraDistance < 10: hero.cast("regen", "Chandra") else: # If you aren't casting "regen", use "if" and "distanceTo" # to attack enemies that are closer than hero.attackRange. enemy = hero.findNearestEnemy() hero.attackRange - 30 hero.attack(enemy) pass
