Basic Coding Concepts in GDScript

Which of the following is a correct variable declaration in Godot? (Select 3)

• var points: int = 0

• var myVariable: int

• let myVariable = int

• var myVariable: float = 3.14

• var float: int = 34

Answer explanation

The correct syntax for a variable declarations in Godot is var [valid variable name] : [data type] = [value]. This means that the correct variable declarations are 'var points: int = 0', 'var myVariable: int', and 'var myVariable: float = 3.14'. var myVariable: int simply means that myVariable currently has no value in it.

Complete the line of code below to correctly define a constant float variable in GDScript.

​ (a)   pi: ​ float = ​ (b)   ​

• const

• 3.14

• def

• 57

Answer explanation

To define a constant float variable in GDScript, 'const' is used followed by the variable name 'pi' and its value '3.14'.

Which of these data types are supported in GDScript? (Select 3)

• Double

• Char

• Integer

• Float

• Bool

Answer explanation

The basic data types supported in GDScript are Integer, Float, and Bool. Double and Char are not basic data types in GDScript.

What are the different types of conditional statements in GDScript? (Select 2)

• if

• for

• else

• when

• elif

Answer explanation

The different types of conditional statements in GDScript are 'if' and 'elif'. 'if' is used for the primary condition, while 'elif' is used for additional conditions after the initial 'if' statement.

What is the purpose of loops in programming?

• The purpose of loops in programming is to automate the execution of repetitive tasks.

• Loops are designed to execute tasks only once in programming

• The purpose of loops is to slow down the program execution

• Loops in programming are used to create chaos and confusion

Answer explanation

The purpose of loops in programming is to automate the execution of repetitive tasks.

What are the types of loops available in GDScript? (Select 2)

• while

• do-while

• repeat

• for

• when

Answer explanation

The types of loops available in GDScript are 'while' and 'for'. 'while' is a pre-test loop, and 'for' is a loop that iterates over a sequence of values.

How do you write a for loop in GDScript? (Select 2)

• for (i = 0; i < 10; i++):

• for i = 0 to 10:

• for i in range(0, 10):

• for i in range(10):

• for range(0, 10):

Answer explanation

The correct way to write a for loop in GDScript is 'for i in range(10):'. This syntax iterates over a range of numbers from 0 to 9.

What is a function in programming?

• A function in programming is a block of code that performs a specific task.

• A function in programming is a variable that stores data

• A function in programming is a loop that repeats a set of instructions

• A function in programming is a comment that explains code

Answer explanation

A function in programming is a block of code that performs a specific task.

What is the difference between a function and a method in GDScript?

• A function is standalone, while a method is associated with an object or class.

• A function is associated with an object, while a method is standalone.

• A function can only be used in classes, while a method can be used anywhere.

• A function can access class variables, while a method cannot.

Answer explanation

A function is standalone, while a method is associated with an object or class. In GDScript, functions can exist independently, while methods are tied to objects or classes.

Complete the line of code below to declare a String array with the name enemyAttack and the item "Blizzard" on index 1.

​ (a)   ​ (b)   = [​ (c)   , ​ (d)   , "Thunder"]

• var
• def

• enemyAttack
• "Fire"
• "Blizzard"
• enemy Attack

Answer explanation

The correct choices to declare a String array with 'Blizzard' on index 1 are 'var', 'enemyAttack', 'Fire', and 'Blizzard'. Since the first item on an array is index 0, "Blizzard" should be on the second blank.
