Add Colour

• Create a new folder by clicking Assets > Create > Folder, and call it Materials.

• Now make two materials (Assets > Create > Material) called EyeBlack and NoseRed.

• The two new materials should be in the Materials folder you just made, inside the Project pane at the bottom of the screen. If they are not there, drag them onto the the Materials folder to place them inside it.

• You can set the colour of a material by changing its albedo value in the Inspector. Click on the rectangle next to the dropper icon, and a colour picker should open.

• Make EyeBlack’s albedo value black, and NoseRed’s albedo value red.

• Select the Shades object, look at the Mesh Renderer section of the Inspector, and expand the Materials subsection. Click on the small circle to the right of Element 0 and select EyeBlack. Now MazeRobo has black shades!

• Do the same for the Nose object as you did for the Shades object, only now select the NoseRed material. Now you have given MazeRobo a red nose!

Giving your robot rules

MazeRobo needs a Rigidbody component so that you can move her about and let her interact with the world.

• With MazeRobo selected, click on Component > Physics > Rigidbody. This will let you set rules for how MazeRobo behaves in the game.

• You’ll see now that when you have MazeRobo selected, there’s a Rigidbody section in the Inspector. Open up the Constraints subsection of the Rigidbody section, and set Freeze Rotation X, Y and Z to True by clicking in all the boxes. In Freeze Position, set Y to True by clicking that box.

• Now you have a basic robot character you can use in your game. You can really make it your own by changing a few colours around, or maybe adding extra pieces to it using more 3D Objects that you can position, like you did in the last step! Once you’re happy with your robot, move on to the next step.
