Sneak peek #1 ;

I am using the program Scratch to create a game that can broaden my knowledge of how technology works in this aspect of gaming.

The concept of my game is a restaurant-waitress game with the setting of McDonalds used. The sprites used is a customer, a computer, coke, a burger, chips and ice cream. I have used the option to make a sprite to create choices i.e. Instructions, Play etc. Because it is a very complex and difficult to create, I have only worked on one level consisting of one customer with one order. To make things easier, there is a scoreboard following the cash achieved throughout the first level. The players are able to choose which level they would like to participate in i.e. level 1-3.

Scratch Challenge #1 ;

Have your sprite glide across the screen and when it touches the edge (note: the “edge” can be sensed as a standard function), have it change directions.

Sample Flowcharts ;

1. For each of the following flowcharts, describe in words what you think they will do.

For the first flowchart, I can assume that the process revolves around the temperature of the climate. First:
1. The start button means to begin the task
2. Read temp means to read the temperature in a specific location
3. If the temperature is less than 32, it will lead you to the button: Print "Bellow Freezing". If the temperature is more than 32 degrees, it will  lead you to the button: Print "Above Freezing"
5. Either way, the process will finish by showing the button End

For the second flowchart, it demonstrates the process of a one second response to a switch.
1. The start button means to execute the action
2. If the switch is not on, turn the LED on
3. Then you will need to start timer to have 1 second expired
4. If one second has expired, you turn the LED off
5. When the LED is off, you reset timer.
6. That is the end of the demonstration

 



2. Convert one of the algorithms you have created in the previous task into a flowchart, e.g.  opening a door, moving through a traffic light.

Start > Find designated door > Did you find the door? (NO) < (YES) > Grasp door handle / unless there is no door handle, push or pull open > If there is a door handle, twist or pull it > Open door fully > Enter room > Close or leave door open > End.

Step 2; Introduction to Algorithms

Define the following terms:

a) Algorithms: A process or set of regulations to be followed in calculations or other problem-solving operations, esp. by a computer.

b) Pseudocode: A notation resembling a simplified programming language, used in program design.

c) Machine Language: It is a system of instructions and data executed directly by a computer's central processing unit.

d) High Level Computer Language: A programming language enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages.

e) Flowchart: A graphical depiction of the flow of execution in a program or algorithm.

f) Sequence: In a sequence structure, an action, or event, leads to the next ordered action in a predetermined order. The sequence can contain any number of actions, but no actions can be skipped in the sequence. The program, when run, must perform each action in order with no possibility of skipping an action or branching off to another action.

g) Selection: In a selection structure, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event.

h) Repetition: In a loop structure, the program asks a question, and if the answer requires an action, it is performed and the original question is asked again until the answer is such that the action is no longer required.

Write an algorithm for the following processes:
1. Opening a door and entering a room
1. You walk to the door.
2. You grasp onto the door knob / you push or pull the door if there is no knob.
3. You twist or pull the door knob
4. Pull or push the door while twisting or pulling the door knob.
5. You walk into the room
6. Close the door or leave it open

2. Negotiating traffic lights as you drive down a street.
1. Start driving
2. If you are far away from a traffic light, keep driving to your destination
3. If the light turns orange and you are near, begin to slow down
4. If the lights are red, stop.
5. Wait for the lights to go green
6. When the lights are green, begin driving

I finished adding the final touches to my powerpoint. The final changes I have applied to my ebook are the chapters:

Chapter 1: Netbooks

Chapter 2: Types of Ports

Chapter 3: Cloud Computing

Chapter 4: Social Networking

I have added images and the navigation button that leads straight to home, but there are no sounds or animations that are applied in my ebook.
