Cannot read property 'x' of undefined error


#1

can i have help with this definition?
is arch.pos.x not a thing?

def commandArchers():
    archer = hero.findByType("archer")
    enemy = hero.findNearest(hero.findEnemies())
    if archer:
        if enemy:
            if enemy.pos.x + 25 <= 50 :
                hero.command(archers, "attack", enemy)
            else:
                x = archer.pos.x
                y = archer.pos.y
                hero.command(archer, "move", { 'x': x, 'y': y})

thx in advance


#2

and if i use,

def commandArchers():
    archer = hero.findByType("archer")
    enemy = hero.findNearest(hero.findEnemies())
    if archer:
        if enemy:
            if enemy.pos.x + 25 <= 50 :
                hero.command(archers, "attack", enemy)
            else:
                hero.command(archer, "move", archer.pos)

I get a array error on archer in

archer.pos

even though it worked for

if archer:

#3

archerS <=> archer

Maybe that’s the problem


#4

archer in this case is an array. So it should be called archers as that is more descriptive of what is being returned.

therefore archer.pos.x is undefined. however archer[0].pos.x should be defined if there are archers in game.

ok thanks
funny what you miss sometimes
