The fundamental parts, as we need to know essentials to be able to write a script
When is the best time to name a C# script?
Once writing the script has finished, and it is time to run the whole project.
When the new file appears in the Project tab with the filename in edit mode, which will make the class name the same as the filename and prevent naming conflicts
Doesn’t matter. Anytime is a good time to name a C# script.
What is the main purpose of a variable?
Assigning specific value to a defined variable
Storing a specific type of data for use elsewhere in a C# file

Methods store executable lines of code for fast and efficient reuse.
Methods store specific values for later use.
How does a script become a component?
By saving and playing the current scene
By changing the inspector specifications

Using camelCase
There is no restriction on variable names in C#
How do you make a variable appear in Unity’s Inspector window?
Declare the variable as public

When are explicit conversions needed between types?
When conversions take place automatically
When a smaller value will fit into another variable type without rounding
When an implicit conversion doesn’t already exist
Which of these requirements for defining a method?
The type of data returned from the method
The name of the method with parentheses
A pair of curly brackets for the code block
What is the purpose of the parentheses at the end of the method name?
To allow parameter data to be passed into the code block
To distinguish methods from classes
To define new variable
What does a return type of “void” mean in a method definition?
The method can return data, but not for the time being
There is data being returned by this method
The method will not return any data
