0:00:00.840,0:00:01.800
Wow!

0:00:01.800,0:00:03.020
Another three puzzles solved!

0:00:03.020,0:00:05.900
And we've caught...a salmon.

0:00:05.900,0:00:10.580
Not quite as exciting as piles of gold, but[br]we'll take what we can get.

0:00:10.580,0:00:14.429
And I have a feeling that nautilus shell will[br]come in handy later.

0:00:14.429,0:00:17.450
I wonder what lurks in these ruins.

0:00:17.450,0:00:18.840
Perhaps another hint!

0:00:18.840,0:00:21.510
Let’s take a look inside.

0:00:21.510,0:00:24.760
My name is Netty and welcome to my ruins.

0:00:24.760,0:00:28.500
We make decisions all the time based on conditions.

0:00:28.500,0:00:31.540
If it looks like rain, [br]then we’ll grab an umbrella.

0:00:31.540,0:00:34.160
If we’re hungry, then we'll eat a snack.

0:00:34.160,0:00:38.440
If we see a creeper, then we run [br]in the opposite direction.

0:00:38.449,0:00:41.000
Computers make these types of decisions too.

0:00:41.010,0:00:44.460
They can actually respond to [br]conditions using code.

0:00:44.460,0:00:50.700
To program a response like this using your[br]code commands, select an if path block.

0:00:50.700,0:00:53.319
Select the dropdown to create the command.

0:00:53.319,0:00:58.640
For example, if you write the command "if[br]path to the right" and place turn right inside

0:00:58.640,0:01:03.560
the conditional, then when Steve [br]reaches an open path to the right

0:01:03.560,0:01:06.100
he will always turn right.

0:01:06.100,0:01:09.780
If there is no opening to the right, [br]he will not turn right.

0:01:09.780,0:01:14.460
These conditional if commands are helpful[br]when you run code in unpredictable situations

0:01:14.460,0:01:17.860
such as mysterious ruins in underwater caves.

0:01:17.860,0:01:21.200
Try using the if blocks and take your code[br]for a spin.

0:01:21.200,0:01:22.200
Wow!

0:01:22.200,0:01:23.930
Netty’s ruins were awesome.

0:01:23.930,0:01:26.619
I really gotta move out of my parents' house.

0:01:26.619,0:01:27.689
So what do you think?

0:01:27.689,0:01:30.729
Are the conditions right for us to complete[br]the final puzzles?

0:01:30.729,0:01:32.179
Let’s give it a go.
