SCRATCH

This term 4 we will being using the Scratch program to create a game. Scratch is a program that lets you create interactive stories, games, music and art, using control, looks, motion, sensing, operators, sounds, pen and variables blocks.

Moving Animation- Fire Breathing Dragon

Using the tutorial on StudentNet I have learnt how to make a moving animation using the program Scratch.



<----- On the right is the blocks I used to construct the moving dragon which is shown in the above two images. The orange-yellow blocks are used to HOW long the object should move. The purple blocks control what "costume" is shown. With the dragon, there are two costumes. A costume is the object itself. The dark blue blocks are used to control the steps and movement of the object, and the light blue block is user to tell the object WHEN to move.

In these blocks the dragon is: going to start when I press 'space,' repeat until I press the 'down' button, change to 'costume a' (costume 'a' is the dragon with a shut mouth). After that, it'll wait 0.5 seconds until moving 4 steps. Then it'll switch to 'costume b' (costume 'b' is the fire breathing dragon), wait 0.5 seconds, move 4 steps and if the dragon hits the edge it will turn around and REPEAT!!

Opening a door and Entering a room

Using Word I have created a flowchart for the recent algorithm posted on my blog.

Flowcharts!

Pink Chart

In this flowchart the question is asking if the temperature is below 32 degrees. On either side of the diamond are arrows-one labelled "no" and the other "yes"- indicating what your answer may be. Also, on either side both answers end up coming to a dead end, "end."


Blue Chart

This flowchart is for "One Second Response to a switch." Unlike the above flowchart it is more complex with more directions. The diamond below  "start" asks if the the switch is on. If "no" you follow the arrow labelled "no" and continue following until your answer changes to "yes." Once the answer changes to "yes" the direction changes and more instructions are given until you arrive at the next question. In this case, the next question is asking if one second as past. The same with the previous question, if the answer is "no" followed the arrow labelled "no" and do so until your answer changes. Basically, the flowchart could be split into two sections to make simpler but incomplete flowcharts.

ALGORITHMS

Opening a door and entering a room

1. Facing 180 degrees away from the door, turn 180 degrees to face the door.
2. Take 3 steps forward
3. Take one side-step to the right
4. Put your hand out
5. Lower your arm slightly
6. Grab hold of handle/knob
7.  Push handle down or turn knob towards the right until it unlocks
8. Push the door
9. Take 5 steps into the room

TERM 4 DEFINITION

Algorithms
A process or set of rules to be followed in calculation or other problem-solving operations.

Pseudocode
A compact an informal high-level description of a computer programming algorithm that uses the structural convention. (Written in a technical way but cannot be interpreted by a computer but by humans.)

Machine Language
Designed for use on a specific class of computers.

High Level Computer Language
A problem oriented language that uses English-like statements and symbols to create sequences of computer instructions and identify memory locations, rather than the machine-specific individual instruction codes and numerical addresses employed by machine language. (A language understood by both computer and person)

Flowchart
A diagram of the sequence of operations in a computer program or an accounting system.

Sequence
A particular order in which related events, movements or things follow each other.

Selection
The action or fact of carefully choosing someone or something as being the best or most suitable.

Repetition
Repeat a sequence of steps until requirement is satisfied.

FINALLY COMPLETED EBOOK!

I have finally completed my Multimedia Ebook which can now be viewed on share-point.

The program I was originally meant to use was Notland but due to the difficulties I was facing I have decided to use Powerpoint. Though I had no access to Powerpoint on my home PC I looked up the information, saved it and when I got to school I would put the information on the Powerpoint.

My Ebook contains hyperlinks to other slides, videos, images and sound. The easiest part of producing the ebook was making the hyperlinks. The hardest part on the other hand was transferring everything from one computer to another. During the process of the assignment I have learnt how to download videos off Youtube. The Ebook is also 25 slides long. :)
