This document contains a multiple choice quiz about Unity 3D and C#. Unity 3D is a cross-platform game engine that can be used to develop 2D and 3D games and experiences. It uses the C# programming language and supports scripting. The document also provides the names of two students and a link to a presentation they created about Unity 3D. It concludes by listing several references used to create the content in the document.

d) None
8) Is Unity only used for developing 3D games?
a) YES
b) NO
9) Who develop Unity?
a) Microsoft
b) IBM
c) Apple
d) Unity Technologies
10) Unity is written in which programing Language?
a) JAVA
b) C, C++
c) C#
d) Python
11) Can threads be used to modify a Texture on runtime?
a) No. Unity doesn’t allow other threads, besides the main one, to make modifications on these
kinds of data.
b) Yes,Because Texture and Meshes are examples of elements stored in GPU memory
12) Can threads be used to move a GameObject on the scene?
a) No. Fetching the Transform reference isn’t thread safe in Unity.
b) Yes,Because Fetching the Transform reference is thread safe in Unity
.
13) Can two GameObjects, each with only a sphere collider, both set as trigger and
raise OnTrigger events?
a) No. Collision events between two objects can only be raised when one of them has a RigidBody
attached to it.
b) Yes. Collision events between two objects can be raised when one of them has a RigidBody attached
to it.

4. 14) Which of the following examples will run faster?
a) 1000 GameObjects, each with a MonoBehaviour implementing the Update callback.
b) One GameObject with one MonoBehaviour with an Array of 1000 classes,each implementing a
custom Update callback.
15) Arrange the event functions listed below in the order in which they will be
invoked when an application is closed:
Update() ;OnGUI() ;Awake() ;OnDisable() ;Start() ;LateUpdate()
OnEnable() ;OnApplicationQuit() ;OnDestroy()
a) Awake(); OnEnable(); Start(); Update(); LateUpdate();
OnGUI(); OnApplicationQuit(); OnDisable(); OnDestroy()
b) OnGUI(); OnApplicationQuit(); OnDisable(); OnDestroy()
Awake(); OnEnable(); Start(); Update(); LateUpdate();
16) Why vectors should be normalized when used to move an object.
a) Normalization makes the vector unit length.
b) Normalization makes the vector auto increment/decrement.
17) What is vertex shader?
a) Vertex shader is a script that runs for each vertex of the mesh
b) Vertex shader is a script that runs for each fragment of the mesh
18) What a pixel shader?
a) Pixel shader is a script that runs for each fragment after three vertexes are processed in a mesh’s
triangle.
b) Pixel shader is a script that runs for each pixel of the vertex.
19) What is the role of inspector panel in the Unity editor?
a) The inspector panel allows users to modify numeric values drag and drop references of scene
objects

5. b) It shows all the available scripts, textures, materials and shaders available for use in the project.
20) What is the role of project panel in the Unity editor?
a) It shows all the available scripts, textures, materials and shaders available for use in the project.
b) The inspector panel allows users to modify numeric values drag and drop references of scene
objects
