Programming, algorithm by a game / Stage 2=Sky / sky and "for" loop

· We do not acquire personal information and user data

· Do not display advertisements

It is a programming introductory software with game feeling.

Beginners can learn the basics of algorithms.

A small red car moves as you programmed.

Can you make the red car "RedNose" goal?

This "Sky" is the second stage. The car runs on the road and fly in the sky.

Please also try it a fixed number of times.

In this stage 2 "Sky"

· The sense of direction is taken care of.

Can you correctly judge the direction change to 8 direction?

· Can you tell the distance and direction so that the car does not get out of the road?

· The car can fly where there are no roads. The car fly to where there is a road.

· If you make a mistake in the program, the car behaves erratically, can you find the cause?

· Can you solve it by using available tools (enlargement, tracing)?

· Can you adapt to the world of distance and direction different from reality?

· Can we use the loop well?

· Please run 30 maps.

In stage 1 "Road", the car will run on the road. First of all, please try from stage 1.

In stage 3 "Loop", the car goes through the maze by judging the state of the road.

●Introduction of available instructions

〇 Instructions that can be used in the 1st stage "Road"

· Run on a road

run distance · · · · Traveling at a specified distance

   run ... Go straight ahead to the end of the road

· Change turn direction

　turn direction ... Change the direction to the specified direction.

　You can specify 8 directions.

· Stop

　stop ... Stop. Determine whether the position is a goal

○ Instructions to be added in the second stage "Sky"

· Fly in the sky

fly distance · · · fly a specified distance

   fly · · · go straight and fly to where there are roads

· a fixed number of iterations

   for times

     processing

   end

○ Instructions added in the third stage "Loop"

· Execute when if condition is satisfied

   if condition

processing

   end

· Execute when if condition is satisfied or when it fails

   if condition

processing when condition is met

   else

     processing when the condition is not established

   end

· Repeat while while condition is satisfied

while condition

     processing to repeat when the condition is satisfied

   end

● About the name Red Nose

Red beetle, red bee, red ladybug, or rather

Such a name is a small car perfect.

This red car, like a mole,

Push the nose paddle against the road and proceed while exploring the way.

Surely its nose rubbed and it must be red.

That is the impression of the developer.

From here, I named it Red Nose.

The best pose is hanging on the corner of the road when the program fails.
