Slalom help with code

This is my code:

// Use object literals to walk the safe path and collect the gems.
// You cannot use moveXY() on this level! Use move() to get around.
gems = this.findItems();

while (this.pos.x < 20) {
	// move() takes objects with x and y properties, not just numbers.
	this.move({'x': 20, 'y': 35});
}

while (this.pos.x < 25) {
	// A gem's position is an object with x and y properties.
	gem0 = gems[0];
	this.move(gem0.pos);
}
while(this.pos.x < 30){
    this.move({x:30,y:35});
}

while (this.pos.x < 35) {
    this.move(gems[1]);
}
// While your x is less than 30,
// Use an object to move to 30, 35.

// While your x is less than 35,
// Move to the position of gems[1].

// Get to the last couple of gems yourself!

When I run this code my hero justs moves to the first X and stays there

***Help pls!!! :cry: ***

is the previous code, you did:

this.move(gems[1]);

should be

this.move(gems[1].pos);

I made that change and a handful of others but my code has an infinity loop could someone find the problem and tell me how to fix it

  //Commented out to stop infinite loop.
// Use object literals to walk the safe path and collect the gems.
// You cannot use moveXY() on this level! Use move() to get around.
gems = this.findItems();

while (this.pos.x < 20) {
	// move() takes objects with x and y properties, not just numbers.
	this.move({x: 20, y: 35});
}

while (this.pos.x < 25) {
	// A gem's position is an object with x and y properties.
	gem0 = gems[0];
	this.move(gem[0].pos);
}
while (this.pos.x < 30 ){
    this.move({x:30,y:35});    
}

while(this.pos.x < 35){
    this.move(gems[1].pos);    
}

// While your x is less than 30,
// Use an object to move to 30, 35.

// While your x is less than 35,
// Move to the position of gems[1].

// Get to the last couple of gems yourself!

this.move(gem[0].pos)

–>

this.move(gems[0].pos)

At first, I missed the additionnal ‘s’ in the nick’s post.
So I tryed your code, and it failled but not with an infinite loop. I got:

which is more clear. Funny you don’t have the correct error message (@nick)

He fixed it(maybe someone else but yeah) and I got past Slalom :smile:

I don’t understand what i’m doing wrong;

# Use object literals to walk the safe path and collect the gems.
# You cannot use moveXY() on this level! Use move() to get around.
gems = self.findItems()

while self.pos.x < 20:
	# move() takes objects with x and y properties, not just numbers.
	self.move({'x': 20, 'y': 35})

while self.pos.x < 25:
	# A gem's position is an object with x and y properties.
	gem0 = gems[0]
	self.move(gem0.pos)

# While your x is less than 30,
# Use an object to move to 30, 35.
while self.pos.x < 30:
    self.move({'x':30, 'y': 35})
# While your x is less than 35,
# Move to the position of gems[1].
while self.pos.x < 35:
    self.move({'x':35, 'y': 25})
# Get to the last couple of gems yourself!
while self.pos.x < 40:
    self.move({'x':40, 'x': 25})
while self.pos.x < 45:
    self.move({'x':45, 'y':35})
while self.pos.x < 50:
    self.move({'x':50, 'y':45})

I tried this level but when I did it half way through he just walked away into the cliff?
This is my code.

// Use object literals to walk the safe path and collect the gems.
// You cannot use moveXY() on this level! Use move() to get around.
gems = hero.findItems();

while (hero.pos.x < 20) {
    // move() takes objects with x and y properties, not just numbers.
    hero.move({'x': 20, 'y': 35});
}

while (hero.pos.x < 25) {
    // A gem's position is an object with x and y properties.
    gem0 = gems[0];
    hero.move(gem0.pos);
}

// While your x is less than 30,
// Use an object to move to 30, 35.
while (hero.pos.x < 30) {
    hero.move({'x': 30, 'y': 35});
    }
// While your x is less than 35,
// Move to the position of gems[1].
while (hero.pos.x < 35) {
    gems1 = gems[1];
    hero.move(gems1.pos);
    }
// Get to the last couple of gems yourself!
while (hero.pos.x < 40) {
    hero.move({'x': 40, 'y': 45});
    }
while (hero.pos.x < 45) {
    gems2 = gems[2];
    hero.move(gems[2].pos);
    }
    while (hero.pos.x < 50) {
    hero.move({'x': 50, 'y': 55});
}
while (hero.pos.x < 55) {
    gems3 = gems[3];
    hero.move(gems[3].pos);
    }

You are missing an s in gems

Edit: oops I relied to the wrong post, hold on i will make a reply to the right one…

Working on it

You are incrementing the y coordinate in your move orders, the y is how much you walk in the UP (north) direction, you should keep y at 35 in all of them.

I don’t know if this is easier for anyone else, but for me personally I found the best way to complete it was using two Arithmetic Series. It reduced the whole program too minimal lines. If you have covered it in school give it a try.

# Use object literals to walk the safe path and collect the gems.

gems = hero.findItems()

while hero.pos.x < 20:
	# move() takes objects with x and y properties, not just numbers.
	hero.move({'x': 20, 'y': 35})

while hero.pos.x < 25:
	# A gem's position is an object with x and y properties.
	gem0 = gems[0]
	hero.move(gem0.pos)

# While your x is less than 30,
# Use an object to move to 30, 35.
while hero.pos.x < 30:
    hero.move({'x': 30, 'y': 35})

while hero.pos.x < 30:
    gem1 = gems[1]
    hero.move(gem1.pos)
# While your x is less than 35,
# Move to the position of gems[1].
while hero.pos.x < 35:
	# move() takes objects with x and y properties, not just numbers.
	hero.move({'x': 35, 'y': 35})

while hero.pos.x < 35:
	# A gem's position is an object with x and y properties.
	gem1 = gems[1]
	hero.move(gem1.pos)
# Get to the last couple of gems yourself!
while hero.pos.x < 40:
	# move() takes objects with x and y properties, not just numbers.
	hero.move({'x': 40, 'y': 35})

while hero.pos.x < 45:
	# A gem's position is an object with x and y properties.
	gem3 = gems[3]
	hero.move(gem3.pos)

i dont know what im doing wrong

Could you please remove the comments from the code and give more info about what is happening when you run your code.
