Python Arcade – Display Text

0 0 2 minutes read

In this article, we will learn How we can add text to arcade games in Python.

Adding Simple Text

We can add text in the arcade using the draw_text() function.

Syntax: arcade.draw_text(text, x, y, color, size, width, align, font_name)

Parameters:

text: Text we want to display

x : x coordinate

y : y coordinate

color : color of the text

size : Size of the font

width : Width of the text

align : Alignment of the text

font_name : Name of the font

In the below example, we are going to create a class named MainGame, and inside this class, we will create an on_draw() function in which we will do the rendering and drawing of our text. Then we will call our MainGame() class and arcade.run() function.

Below is the implementation:

Python3

# Importing arcade module 
import arcade 
  
# Creating MainGame class        
class MainGame(arcade.Window): 
    def __init__(self): 
        super().__init__(600, 600, 
                         title="Text in Arcade") 
  
  
    # Creating on_draw() function to draw on the screen 
    def on_draw(self): 
        arcade.start_render() 
          
        # Drawing the text using draw_text() 
        # draw_text function is used to draw  
        # text to the screen using Pyglet’s label. 
        arcade.draw_text("zambiatek",120.0,300.0, 
                         arcade.color.GREEN,40,80,'left') 
  
# Calling MainGame class        
MainGame() 
arcade.run() 

Output:

Updating the Text

In this example, we are going to display the score as text and we want to increase the score by 10 points every time the player touches the border of the screen. For this, we are going to initialize some variables for the x and y coordinates, score, and velocity of the player in our MainGame class. After that, we will create 2 functions:

on_draw(): We will draw our player and text inside this function.
on_update(): We will update the x coordinate of the player by adding velocity. Then we will change the player’s direction and increase the score if the player crosses the boundaries of the screen. After this, we will call our MainGame() class.

Below is the implementation:

Python3

# Importing arcade module 
import arcade 
  
# Creating MainGame class        
class MainGame(arcade.Window): 
    def __init__(self): 
        super().__init__(600, 600, title="Player Movement") 
  
        # Initializing the initial x and y coordinated 
        self.x = 250 
        self.y = 250
  
        # Creating variable to store the score 
        self.score = 0
  
        # Initializing a variable to store 
        # the velocity of the player 
        self.vel = 300
  
    # Creating on_draw() function to draw on the screen 
    def on_draw(self): 
        arcade.start_render() 
  
        # Drawing the rectangle using 
        # draw_rectangle_filled function 
        arcade.draw_rectangle_filled(self.x, self.y,50, 50, 
                                     arcade.color.GREEN ) 
  
        # Drawing the text 
        arcade.draw_text('Score :- '+str(self.score),150.0,500.0, 
                         arcade.color.RED,20,180,'left') 
          
    # Creating on_update function to 
    # update the x coordinate 
    def on_update(self,delta_time): 
        self.x += self.vel * delta_time 
  
        # Changing the direction of 
        # movement if player crosses the screen 
        # and increasing the score 
        if self.x>=550 or self.x<=50: 
            self.score += 10
            self.vel *= -1
          
# Calling MainGame class        
MainGame() 
arcade.run()
