Gamespace: Player

Next I decided to add functionality to the sphere so that the player can control the object in the Gamespace.


Player controlling ball in Game View

The sphere needed a Rigidbody in order to use gravity and not fall through the floor.
The 'RollingBall' script was attached so that the player could control the ball using keyboard commands and allowed a force to be multiplied and added to the ball.


Player Inspector

The variable 'ForceMultiplyer' was declared as a public float so that the value could be edited outside the code.
The 'forward' and 'right' variables are set to zero as a default.
The if statement states that:
If the 'W' key is pressed move the player forward = 1 on the Z-axis causing the player to move forward.
If the 'S' key is pressed move the player forward = - 1 on the Z-axis causing the player to move backwards.
If the 'D' key is pressed move the player right = 1 on the X-axis causing the player to move right.
If the 'A' key is pressed move the player right = - 1 on the X-axis causing the player to move left

A 2D vector is created named 'direction' which maps the 'forward' and 'right' variables on the X and Y-axis'.

The rigidbody component is received and allows us to add force to the ball including the direction of the object.
A new 3D vector is created allowing the variables 'right' to be mapped onto the X-axis, 0 to be mapped onto the Y-axis (as I do not want the ball to travel in this direction) and 'forward' to be mapped onto the Z-axis. The vector is also multiplied by the score multiplier variable, adding more force to the ball.

If the 'Space' key is pressed, the ball will jump.
This occurs due to the rigidbody component being received. A new 3D vector is created and the AddForce() command has been used to give the object force. The X-axis is set to zero, the Y-axis is set to 100 and the Z-axis is set to zero allowing the object to jump in this direction.

Finished game displayed in the scene view. Scene view Assets Uses Rigidbody so that the ball can use physics (Gravity) therefore it doesn't fall through the ground. The 'Rolling Ball' script is attached to the ball which adds force to the ball. Ball Inspector Scene view displaying the invisible cube object which can be used as a trigger for an event.

When an object does not have a mesh renderer, the object becomes invisible as we cannot see it due to it not having a mesh.

[Research] Traditional Poster Design (4CTA1214)

Image
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
