29
Q

Inheritance

A

the ability to create a class from another class

30
Q

MonoBehaviour class

A

MonoBehaviour is the base class from which every Unity script derives

31
Q

collider

A

A base class of all colliders.

32
Q

pseudocode

A

a simplified programming language that is easier to understand

33
Q

transform component

A

a component that allows you to move or change an objects size through the script

34
Q

localScale

A

uses the Vector3 scale to change a game objects scale in a specific way

35
Q

vector

A

This structure is used throughout Unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.

36
Q

scaling a vector (vector multiplication)

A

Vector3(3,4,5) would send it right by 3 points,up by 4, and forward by 5.

37
Q

vector’s magnitude

A

returns the length of a vector

38
Q

unitary vector

A

has a vector of 1

39
Q

normalized vector

A

makes the vector have a magnitude of 1

40
Q

Vector class

A

Vector3(x, y, z)

41
Q

Update() method

A

called every frame if enabled

42
Q

refactoring code

A

Refactoring is the process of improving your code after it has been written by changing the internal structure of the code without changing the external behavior of the code.

43
Q

Game Design Document (gdd)

A

Short document to describe a game concept, for yourself or your team.
Things to include: description, concept art, assets
game mechanics: controls, UI, and camera

44
Q

speed distance and time formulas

A

The triangles will help you remember these 3 rules: Distance = Speed x Time.

45
Q

Time.deltaTime

A

The time in seconds it took to complete the last frame (Read Only).

46
Q

Transform.Rotate

A

Applies a rotation of eulerAngles.z degrees around the z axis, eulerAngles.x degrees around the x axis, and eulerAngles.y degrees around the y axis (in that order).

47
Q

Prefab

A

Prefab asset type that allows you to store a GameObject object complete with components and properties.

48
Q

Input (unity class)

A

Use this class to read the axes set up in the Input Manager, and to access multi-touch/accelerometer data on mobile devices.

49
Q

Horizontal Axis (input manager)

A

commands that allow the player object to move horizontally

50
Q

Vertical Axis (input manager)

A

commands that allow the player object to move vertically

51
Q

Input.GetAxis() method

A

Returns the value of the virtual axis identified by axisName.

52
Q

ternary operator

A

The conditional operator (?:) returns one of two values depending on the value of a Boolean expression.

53
Q

Rigidbody class

A

Control of an object’s position through physics simulation.

54
Q

C# Generics

A

Generics allow you to define type-safe classes without compromising type safety, performance, or productivity.

55
Q

GetComponent

A

Returns the component of Type type if the game object has one attached, null if it doesn’t.

56
Q

FixedUpdate() method

A

This function is called every fixed framerate frame, if the MonoBehaviour is enabled.

57
Q

Rigidbody.AddForce()

A

Force is applied continuously along the direction of the force vector. Specifying the ForceMode mode allows the type of force to be changed to an Acceleration, Impulse or Velocity Change.

58
Q

Collider class (component)

A

If the object with the Collider needs to be moved during gameplay then you should also attach a Rigidbody component to the object. The Rigidbody can be set to be kinematic if you don’t want the object to have physical interaction with other objects.

59
Q

physics.Raycast()

A

Casts a ray, from point origin, in direction direction, of length maxDistance, against all colliders in the scene.

60
Q

Static objects

A

The inspector for a GameObject has a Static checkbox and menu in the extreme top-right, which is used to inform various different systems in Unity that the object will not move.

61
Q

Kinematic objects (isKinematic boolean on RIgidBody object)

A

Controls whether physics affects the rigidbody.

62
Q

Trigger objects (isTrigger boolean on Collider Object)

A

detect when an object is within a particular space in the game world.

63
Q

OnTriggerEnter(Collider other) method

A

OnTriggerEnter is called when the Collider other enters the trigger

64
Q

Awake() method

A

Awake is called when the script instance is being loaded.

65
Q

static variables (class level variables)

A

static - the same variable is shared by all instances of the class that are created, and can be private, protected or public.

66
Q

Scene manager class

A

Scene management at run-time.

67
Q

HUD (heads up display) manager

A

68
Q

Text Class

A

The default Graphic to draw font data to screen.

69
Q

FindObjectOfType() method

A

Returns the first active loaded object of Type type.
