# Kelvintaph Burgler: Trying to run away from Chieftain [Solved]

In the Kelvintaph Burgler level I want my archers to fire at the chieftain but from a distance so he can’t attack them. I’m trying to use vectors (unsuccessfully) My archers (I’m only trying to implement it for one of them at the moment) keep running directly into the chieftain and get killed.

Can anyone give me some idea what I’m doing wrong please I’m not great with Vectors at the moment.

The bit of code relating to the archer movement is here and the full code is below it.

``````        if archers[0]:
targetPos=chieftains[0].pos
#hero.say(archers[0]+ ' '+archers[0].pos)
distance=archers[0].distanceTo(targetPos)
#hero.say(archers[0]+ ' distance '+distance)
if distance<15:
#hero.say(archers[0]+ ' distance '+distance)
chfVector=Vector.subtract(archers[0].pos,targetPos)
chfVector1=Vector.normalize(chfVector)
chfVector15=Vector.multiply(chfVector1,15)
hero.command(archers[0],'move',moveToPos)
#hero.command(archers[0],'attack',chieftains[0])
if archers[1]:
#hero.command(archers[1],'attack',chieftains[0])
pass
if soldiers[0]:
hero.command(soldiers[0],'attack',chieftains[0])
if soldiers[1]:
hero.command(soldiers[1],'attack',chieftains[0])
commandPalatt()
``````

The full code is here:

One question, how far are you in code combat? If you are past the desert, i can’t help you.

This is in Kelvintaph Glacier…

how did you know? 20

Cause i’ve did the level. And the level has KELVINTAPH in the name.

Hi,

Yes it is in Kelvintaph Glacier.

I’m finding the Vector stuff a bit tricky.

I think this bit is the bit which is wrong. If you make a vector between the archer and the chieftain, then add that vector to the archer’s position, moveToPos will be the chieftain’s exact position. Essentially you worked out the difference between your archer and the chieftain in a vector, but then you just added the difference to the archer’s position, so you made its target the chieftain’s position. Instead you want to subtract the difference from the archer’s position, so the archer’s target will be directly opposite the chieftain’s position.

Thanks very much Danny. I have managed to mess up the rest of my code (the hero bit) but thanks for the explanation I’ll give this a go.

Yay it worked the archer ran away (into the Yak so he can’t really fire any arrows, however it is definitely a start . Thanks v much!
