I’m trying to do this level but my character just gets into a loop. Can someone help?

```python
#lpx and lpy == lastPositionX and lastPositionY
x = hero.pos.x
y = hero.pos.y
while True:
    downClear = hero.isPathClear(hero.pos,{'x':hero.pos.x,'y':hero.pos.y - 16})
    if downClear and y - 16 != lpy:
        lpx = x
        lpy = y
        y-=16
        hero.moveXY(x,y)
    leftClear = hero.isPathClear(hero.pos,{'x':hero.pos.x + 16, 'y':hero.pos.y})
    if leftClear and x - 16 != lpx:
        lpx = x
        lpy = y
        x+=16
        hero.moveXY(x,y)
    rightClear = hero.isPathClear(hero.pos,{'x':hero.pos.x- 16, 'y':hero.pos.y})
    if rightClear and x + 16 != lpx:
        lpx = x
        lpy = y
        x-=16
        hero.moveXY(x,y)
    upClear= hero.isPathClear(hero.pos,{'x':hero.pos.x,'y':hero.pos.y + 16})    
    if upClear and y + 16 != lpy:
        lpx = x
        lpy = y
        y+=16
        hero.moveXY(x, y)

```

Hey there!  
Before anything else, you’ve got a mistake on left and right checks I believe!  
on the _isPathClear function_ you pass hero’s position **+16** and in the if-block after that you check if you’ve been to hero’s position **-16** and the other way around for right.

What you could do now would be to define an array of “positions you’ve been to before” and a function that would check the position passed by iterating through the array and checking if one of these match and if not would return true. That way you’re sure to **never** go to a position you’ve been to before. Just an idea 😄  
Because right now, you just check the last position you’ve been to.

someone please help me this is my code

```python
# Find the treasure inside the maze.
# When you get the treasure, move to the exit.
# The exit is marked by the red cross. The level ends when you step on the mark.
# Some doors are blocked, some open when you are near them.

        x += 16
    elif n == 2:
        y -= 16
    else:
        x -= 16
    return {"x": hero.pos.x + x, "y": hero.pos.y + y}

while True:
    jMod = 0
    doNext = True
    lastStep = (steps[-1] + 2) % 4
    yDif = hero.pos.y - chest.pos.y

            jMod = 3
    # hero.say(jMod)
    for j in range(4):
        i = (j + jMod) % 4
        checkPoint = direction(i)
        if hero.isPathClear(hero.pos, checkPoint) and walls[len(steps)][i] == 0 and i != lastStep:
            hero.moveXY(checkPoint.x, checkPoint.y)
            steps.append(i)
