Appending Array in Godot

An array is a collection of one or more values of the same type. Each value is called an element of the array. The components of the array share the same variable name, but each part has its unique index number (also known as a subscript).

An array can be of any type, for example, int, float, char, etc.

Always remember arrays always start from their index value, and the index of the array is begun from 0 to n-1.

Suppose we want to access the 5^th element of the array, then we will help us 4^th element because arrays start from 0, and the array is always stored in contiguous memory locations. The number of elements and types of array identified by the subscript of array elements. The various types of Array that are provided by c as follows:-

Single Dimensional Array
Two dimensional Array
Three dimensional Array
Character Array or String

Single dimensional Array

A dimensional is used representing the elements of the array

for example

int a[5]

The [] is used for dimensional or the subscript of the array that is generally used for declaring the elements of the array.

For Accessing the Element from the collection, we can use the Subscript of the Array like this

a[3]=100

This will set the value of the 4^th element of an array

So there is only the single bracket then it called the Single Dimensional Array

This is also called as the Single Dimensional array

Two Dimensional Arrays or matrix

The two-dimensional array is used for representing the elements of the array in the form of the rows and columns, and these are used for representing the matrix A two-dimensional array uses the two subscripts for declaring the elements of the Array Like this int a [3] [3]

Multidimensional or Three Dimensional Array:

The multidimensional array is used for representing the total number of tables of matrix A three-dimensional array is used when we want to make the two or more tables of the matrix elements for declaring the array element we can use the way like this

Int a [3][3][3]

This first 3 represents the total number of Tables, and the second 3 represents the total number of rows in each table, and the third 3 represents the total number of columns in the tables.

So this makes the 3 tables having the three rows and the three columns the primary and essential thing about the array that the elements are always stored in the contiguous in the memory of the computer.

Character Array of String

As an integer, the character is also in the Array. The array of characters is called the strings; they are generally used for representing the strings always remember that a string is terminated with the o or null character.

There is the built-in string operation; the C language in the string provides those.h header file like

strLen: For getting the Length or total numbers of characters in a string
strconcat: This is used for joining the two strings, or this function is used for concatenating the two strings.
strRev: This function is used for obtaining the reverse of the string
strcmp: This function is used for comparing the Two strings, and it gives us the result as follows after comparing the two strings.

Open Godot Engine, then click on the script.

Code:

  extends Control  var player_words=[] #array  var story= “There are sometrees of %s and %s in the %s garden. And a %s morning”   var prompts = [“MANGO”, “Papaya”, “Glorious”,”pleasant”]   #Using PlayerText, DisplayText, And VBox and HBoxContainer.  onready var PlayerText= $VBoxContainer/HBoxContainer/PlayerText  onready var DisplayText= $VBoxContainer/DisplayText      #func _ready():   #DisplayText.text= story%prompts  func _on_PlayerText_text_entered(new_text):  update_DisplayText(new_text)  story=””  #Using Button   func _on_TextureButton_pressed():  var words= PlayerText.text  update_DisplayText(words)  func update_DisplayText(words):  $VBoxContainer/DisplayText.text= words  $VBoxContainer/HBoxContainer/PlayerText.clear()  

Screenshot:

Updated coded part:

  extends Control  var player_words=[]  var story= “There are many trees of %s and %s in the %s amazing garden. And a %s morning”   var prompts = [“MANGO”, “Papaya”, “Glorious”,”pleasant”]  onready var PlayerText= $VBoxContainer/HBoxContainer/PlayerText  onready var DisplayText= $VBoxContainer/DisplayText  func _ready():  DisplayText.text= story%prompts  func _on_PlayerText_text_entered(new_text):  update_DisplayText(new_text)            story = “”  func _on_TextureButton_pressed():  var words = PlayerText.text  update_DisplayText(words)  func update_DisplayText(words):  $VBoxContainer/DisplayText.text=words  $VBoxContainer/HBoxContainer/PlayerText.clear()  func add_to_player_words():  player_words.append(PlayerText.text)  

If we press any function with the ctrl button, then we see the description and type of function like below we click on size () then the following description will open.

Complete Code:

  extends Control  var player_words=[]  var story= “There are many companies like of %s and %s are in the %s section. And many %s companies also which are help under forture 500”  var prompts = [“a company name”, “a mnc company name”, “adverb”,”adjective”]  onready var PlayerText= $VBoxContainer/HBoxContainer/PlayerText  onready var DisplayText= $VBoxContainer/DisplayText  func _ready():  check_player_words_length()    func _on_PlayerText_text_entered(new_text):  add_to_player_words()    func _on_TextureButton_pressed():  add_to_player_words()  #Using TextureButton  func add_to_player_words():  player_words.append(PlayerText.text) #Using .append method  PlayerText.clear()  check_player_words_length() #Players word count to calculating length  func is_story_done():  return player_words.size() == prompts.size() # here we are using array .size method  func check_player_words_length():  if is_story_done():  tell_story()  else:  prompt_player() # Using If/Else condition to check the logic  func tell_story():  DisplayText.text= story % player_words  func prompt_player():  DisplayText.text = “May I have” +prompts[player_words.size()]+”please?” #For displaying question to player or user.  

Then we run the code the output will be like this:

After this question and answers, the story will be generated below:

Now we can change some DisplayText also as our wish as we do: And at the end, we should add a Plus (+) sign to add the display text into it.

These lines are the added lines.

Updated code is:

  extends Control  var player_words=[]  var story= “Optimism is the %s that leads to %s. Nothing can be done without %s and %s.”  var prompts = [“a verb”, “a noun”, “verb”, “adjective”]  onready var PlayerText= $VBoxContainer/HBoxContainer/PlayerText  onready var DisplayText= $VBoxContainer/DisplayText  func _ready():  DisplayText.text=”Welcome all of u in the world of game and have a wondeful time!” # added line  check_player_words_length()    func _on_PlayerText_text_entered(new_text):  add_to_player_words()    func _on_TextureButton_pressed():  add_to_player_words()     func add_to_player_words():  player_words.append(PlayerText.text)  DisplayText.text=”” # Added line  PlayerText.clear()  check_player_words_length()    func is_story_done():  return player_words.size() == prompts.size()    func check_player_words_length():  if is_story_done():  tell_story()  else:  prompt_player()    func tell_story():  DisplayText.text= story % player_words    func prompt_player():  DisplayText.text += “May I have” +prompts[player_words.size()]+”please?”  

Output after adding lines:

And here the story is ready.
