Unity Project 4: Ball platformer game (Code Explained)

'RollingBall' script allows the ball to be moved by the player using the 'W, A, S, D' keys. When any of these buttons are pressed then the ball will move in the direction that has been set in the code. When the space key is pressed, the ball jumps and again uses force of the object's Rigidbody.

Moreover, the script adds force to the Rigidbody of the object making the ball a little bit more difficult to control. The value can be edited in the scene view.

RollingBall script

The script rotates the two cubes which look like a windmill.
Transform.Rotate allows the arms to rotate around the same axis.
The speed is set in the scene for the windmill.

RotatingWindmill script


When the ball collides with whatever object this script is attached to (invisible cube) then the word 'COLLIDED' is printed in the console.

This trigger can be used for many different aspects in a game. This may include: spawning enemies, losing/gaining health, activating a door to be opened/closed, playing music/sounds etc.


Trigger script

Follow Target script allows the camera to follow the ball (Target). 
An offset has been applied so that if wanted the ball can be seen slightly ahead of view, making it easier to control.

[Research] Traditional Poster Design (4CTA1214)

As you can see from the superman poster, there are only four main colours used which includes red, blue, yellow and brown. All elements are filled in with block colours with no shading which was a common colour theme for traditional posters of this kind. This poster may have been used to advertise a new Superman comic or movie depending on the year it was created. The expression on the characters face fits the title shown on the poster explaining that he is returning. This poster advertised Coca Cola, and looks as though this specific poster was used in the USA - due to the currency used. The whole aim of the poster is to incorporate this drink into working peoples daily lives. This is seen by the slogan, 'Work refreshed' and the small graphics on the bottom right of the poster. Displayed is a man working in a factory environment and a lady is working in an office environment both drinking cola during their breaks - to feel refreshed. In some ways the bottle and
