As for this time, it’s fine
Get the hero and the peasant to the south.
The function move your hero down along the center line.
def moveDownCenter():
x = 40
y = hero.pos.y - 12
hero.moveXY(x, y)
The function build a fence on the right of something.
def buildRightOf(something):
# buildXY a “fence” 20 meters to something’s right.
x = 40 + 20
y = hero.pos.y
hero.buildXY(“fence”, x, y)
pass
The function build a fence on the left of something.
def buildLeftOf(something):
# buildXY a “fence” 20 meters to something’s left.
x = 40 - 20
y = hero.pos.y
hero.buildXY(“fence”, x, y)
pass
while True:
ogre = hero.findNearestEnemy()
coin = hero.findNearestItem()
if ogre.pos.x < 40:
buildRightOf(ogre)
elif:
buildLeftOf(ogre)
elif coin:
hero.move(coin)
moveDownCenter()
pass
So in both of the functions that you build in them, the x should be +20 or -20 the position of the parameter you entered in paranthesis called “something”, try that, if it didn’t work, then please post your code after editing
