Java Programming

Session 2

Objectives

• To design a range of different ‘blocks’

• To create the code for these blocks

• To test that each block rotates correctly

• To alter the code to select random blocks

Block Rotation 1

piece_Toppiece_Leftpiece_Bottompiece_Right

Block Rotation 2

piece_Toppiece_Leftpiece_Bottompiece_Right

Block Coding

piece_Top { BLUE , BLUE , NONE }, { BLUE , NONE , NONE }, { BLUE , NONE , NONE }

piece_Left { BLUE , BLUE , BLUE }, { NONE , NONE , BLUE }, { NONE , NONE , NONE }

piece_Bottom { NONE , NONE , BLUE }, { NONE , NONE , BLUE }, { NONE , BLUE , BLUE }

piece_Right { NONE , NONE , NONE }, { BLUE , NONE , NONE }, { BLUE , BLUE , BLUE }

Fitting Blocks Together

Remember that the shapes you make must fit together without leaving gaps

Some shapes are more difficult to fit together than others

Don’t make a shape that will be impossible for the person playing the game

Tasks:

• Design a piece

• Modify the code

• Test the piece rotates well

• Keep doing this until you have lots of good pieces.

• Switch to random piece generation and try it out.
