Make the World’s Ground

Now you’re going to create a ground plane for MazeRobo to move about on!

• Start by adding a Quad object to be the ground (GameObject > 3D Object > Quad). Change the name of this object from Quad to Ground in the Inspector.

• In the Inspector for this new object under Transform, set the X Rotation to 90, and for Scale, enter these values:

  X = 40.96
  Y = 40.96
  Z = 1

  

Gah! MazeRobo’s stuck halfway into the ground! Let’s move her up by one meter.

• Select MazeRobo and, in the Inspector under Transform, set the following Position coordinates:

  X = 0
  Y = 1
  Z = 0

  

Now you’ll add a wall to start your maze!

• Create a Cube (GameObject > 3D Object > Cube) and set its Transform Position to:

  X = -2
  Y = 1.5
  Z = 0

• Set the Y Scale to 3 and rename the object to Wall.

• Now make a new material for Wall (Assets > Create > Materials), rename it WallBlue, and change its albedo to give it a (surprise!) blue colour.

• Assign the WallBlue material to Wall using the MeshRender > Materials section of the Inspector (you can also drag the material straight onto the object).

Later on, you’ll turn this wall into a maze for MazeRobo to explore!
