Resource title: Planning and Programming Task
Student instructions
Introduction
You are required to create a simple game for a class of seven year olds to play. The game should
be animated where the player can move an object up or down to avoid other objects moving left to
right (or right to left) across the game area. You need to decide on how a player is to gain or lose
“points” or gain and lose “lives”.
Specifications:
 On starting the player should be given the game’s instructions.
 The player inputs their name, by entry in a textbox, on the game form. (For higher grades
the name needs to be validated to ensure only letters are entered).

Add “lives” so that if a player loses so many points they lose a life, after losing a specified
number of lives the game ends.

Introduce levels of difficulty, as the player’s score gets higher. (This could be speeding up
objects or slowing them down.).
You will be assessed on:

Your planning (the sketch of your game with necessary controls labelled; investigate the
problem to find the inputs, outputs and processing required so you can identify the variables
required and their data types; pseudo code to specify a procedural structure that combines
actions, conditions and control structures; specifying a set of test cases for the inputs of the

program).

Implementing the plan to write and test the program (evidence of testing can be presented as
a journal or as a collection of annotated screen shots), the way in which you implement the
plan to write and test the program. (You are required to work in an organised and efficient way,
using time effectively.)
Evidence for assessment may be provided in any order and at any stage during the time allocated
for the task.
This is an individual assessment activity. You have until Thursday 29 August in which to
complete the Implementation of this assessment. Your planning/design is due Thursday 8
August
Ensure that in your solution:

there is at least one indexed data structure and the program is decomposed into user-defined
modules with scoped variables, constants and derived values effectively to increase the
flexibility and robustness of the program.
interaction between modules is minimised, modules are reused rather than duplicated, and the
procedural structure of each module is efficient.

Task 1: Planning
Investigate the problem.

Draw a sketch of your game identifying and labelling the control structures (labels, textboxes,
menu items, timer(s) etc.)
Identify and record.

The kind of information that the player will need to input.

The information that will be output by the program.

Processing (basic processes that the program needs to handle e.g. using a timer to move
objects left to right, checking for collisions etc).

Identify the variables and their data types needed to hold the information. (you must include
at least two different kinds of information, for example, text information, numeric information)

Develop the pseudo code to specify a procedural structure that combines actions, conditions
and control structures.

Specify a set of test cases for the inputs of the program (validating the inputs).
Note: Your planning must be submitted Thursday 8 August. This is the assessment for
AS91372 - Digital Technologies 2.45 Construct a plan for an advanced computer program
for a specified task.
Task 2: Programming
Write your program to match the specifications provided, including comments that explain the code.
Task 3: Testing and debugging
Write a list of what you will test the program for, including sample inputs. (test plan)
Test your program, record the results of your testing and fix any errors (debugging)
–
Test that the program works correctly on a sample of expected inputs (normal, nonexceptional, and non-error inputs).

Test that the program works correctly on a range of inputs (some exceptional, out of range,
boundary, or invalid). For example, check that the player’s image cannot move outside the
form’s boundary, that only letters can be input as the player name.
Test the functioning of your program as you make additions or changes to the code. Print
the code; then take screen shots and make written comments describing what works and
what you need to change.
Task 4: Evidence
Collect and annotate evidence (for example, through a journal, a collection of annotated screen
shots, photographs, and/or screen dumps) documenting how you have coded the solution and
followed planned testing procedures.
The evidence should show that you have followed a plan for building your program (for example,
by saving successive versions of code), that you have tested each bit as you have added
complexity, and that you have worked in an organised and efficient way, using time effectively (for
example, not using a trial-and-error approach unnecessarily).
At the end of Week 4 Hand in:
–
A printout of your source code
–
–
An electronic version of your code
All documentation related to testing procedures.
