Can anyone tell me where I am going wrong with this please? My hero picks up the first 3 gems but then runs into the traps.

while True:
    gem = hero.findNearest(hero.findItems())
    if gem:
        clear = hero.isPathClear(hero.pos, gem.pos)
        
        if clear:
            hero.move(gem.pos)
    
        else:
            hero.moveXY(40, 36)

I solved it! I needed to use an object literal in the last line - so that now reads as below.

Can anyone explain why using an object literal worked when the x and y coordinates did not?


        else:
            hero.move({'x' : 40, 'y' : 36})

it’s because when you use hero.move, the statement will run for one step before finishing, meaning that a conditional will instantly update after the statement ran.

compared for moveXY which will only finish after the hero has moved all the way back.

This is important because when you use hero.move the hero will find a clear path to a gem while walking back, and will instantly change course. Comparing this to moveXY, the hero will literally just move into the bear traps before changing course even if it sees a new gem.
