InventionCreating a computer game!

Scratch was the program I chose to create my project.

The tips area was very helpful and shows you step by step instructions on how to create a game. After following the tutorials, it is then much easier to start inventing new elements to your program by following the patterns of data given in the examples.

Press tips for tutorial

AbstractionIn the following slides, I have used abstraction to explain the key steps of creating my game in scratch, without unnecessary details.

Choose a background Click on new backdrops &

choose:• From the library• Draw your own• Upload picture

More than 1 can be chosen to change between.

Data CollectionDefinition - Data collection is the process of gathering and measuring information on targeted variables in an established systematic fashion.

Getting Started!Click on ‘choose sprite’

• From library• Upload or• Draw

Choose a sprite

Animating sprite• Go into costumes

Use the draw option to modify

Select script then looks tab.

By entering in specifications for the algorithm, the computer will change between costume a and b)

Changing your sprites look

Making your sprite move• Go into scripts• Select tab required

Events tab will tell sprite when to will do something(example - when this sprite is clicked)

MotionMotion tab – tell your sprite to move

move -20 steps

move 20 steps

Control key will• add a pause between

commands or • repeat a set of commands.

( wait 0.3 seconds).

Adding soundSound key• from the library• record your own sound• upload a sound

I selected:

• Library – bubble• Record own – I’m hungry

RefiningThe idea was to add text to the different costumes (balls) so they depicted the all of the letters in the alphabet.

When the sprite caught them he would say the letters name and the sound it makes.

Unfortunately was unable to de-bug issues in time frame.

Coding the second & third sprite

Using looping repeats the same algorithm indefinitely.

To add bubbles – (create new sprite)

Sending sprite (ball) to random positions)

Scoring

Implementation

Definition - actual automation of an algorithm (Moodle unit 7)

When these algorithms are initiated, they make the sprite –• look like it is moving• opening/closing claws• & mouth • Bubbles and sounds in

the background• Move sprite to catch

ball• Score
