Helpful Hints

  • The total degree measure of a circle is 360 degrees. Use the following formula to calculate the angle the robot needs to turn to split a specific fraction of the pizza.

Angle_To_Turn = 360 * Fraction 

  • Use the divide block from the Operators category to express the fraction.

    VEXcode Divide block that reads '1 / 3'.

    • Matching Python command:

      1 / 3

  • Use the multiply block from the Operators category to multiply any two values together and report the product.

    VEXcode Multiply block with an added Divide block that reads '360 * 1 / 3'.

    • Matching Python command:

      360 * (1 / 3)

  • Use the fill area with color block from the Looks category to fill an area with a specified color. Move the red, green, and blue sliders in the block to mix primary colors to get blended colors.

    VEXcode Fill area with color block that reads 'fill area with color yellow'.

    • Matching Python command:

      pen.fill(255, 255, 82, 100)
  • The dimension of the VEXcode VR Playground is 2000mm x 2000mm.
