Steps in creating a program write source code / script compile source ( run script) debug ( syntax errors) compile execute test debug ( semantic & logical errors ) execute / test

Program Errors Syntax (compile time) Errors in the way the code is written - missing ; keywords mispelled, lower / uppercase errors Semantic ( run time) Errors in program meaning - assigning an integer to a string type, file read/write io errors, arrays out of bounds errors Logical Errors in program calculation - incorrect output from given input - program works but output results not reliable

Lottery Scenario User enters six numbers - what restrictions? Six numbers, range 1..49, all unique, Computer system selects a set of numbers Same criteria + a bonus ball Selections are compared Display message depending on outcome of comparison All within a multimedia context!

LotteryDraw Class select a random number between store in first array element while numbers to choose < 6 select a random number between 1.49 if number already chosen select a random number between else store in next array element decrement numbers to choose end while

LotteryDraw Class Chooses 7 unique random numbers between constructor - LotterDraw() Private Methods getRandomNumber(int number):void Public Methods chooseNumbers() //creates an array of random numbers getNumber(int number):int // returns the value of the number at the given array // element

Storyboarding

Traditional Storyboading A storyboard is a graphical representation such as a series of illustrations or images displayed in sequence for the purpose of visualizing a motion sequence or interactive media sequence The storyboarding process in the form as used today was developed at the Walt Disney studio during the early 1930s Storyboarding became popular in live-action film production during the early 1940s B.Sc.

Animatic Simplified mock-ups called animatics give a better idea of how the scene will look with motion Usually a series of still images edited together and displayed in sequence Additionally a rough dialogue or sound track is added to the sequence of still images (usually taken from a storyboard) to test whether the sound and images are working well together B.Sc.
