What is Pygame Color?
As you journey into the world of Pygame, you encounter a variety of functions and features that add depth and color to game creation. Speaking of color, Pygame color is an integral part of this game development process. It’s a feature that allows us to change and manage the color elements in our games.
What is it for?
With Pygame color, you can breathe life into your game characters, themes, landscapes and much more. It helps to visually distinguish between different sections of a game, and brings emphasis to parts where required. From setting a thrilling background for your boss fight to driving focus on vital clues in your mystery game, creative use of colors can drastically change the player’s experience.
Why should I learn it?
Understanding and correctly utilizing the power of colors can make your games richer and dynamic. Learning about Pygame colors allows you to experiment with aesthetics and emotional perspectives in game design. A good understanding of Pygame color will move you from a beginner to an advanced game designer, adding a valuable skill in your game development toolkit.
In the next few sections, we will provide some engaging coding examples that give you a hands-on experience on how to use Pygame colors. So stay with us and let’s explore pygames colors in a manner that is beginner-friendly without implying everyone is.
Getting Started with Pygame Colors
To begin, we need to import the pygame module and initialize it. Here’s how to do it:
import pygame pygame.init()
Defining Colors
In Pygame, colors are defined using RGB (Red, Green, Blue) syntax, using values between 0 and 255. Below are examples of how we define colors:
WHITE = (255, 255, 255) RED = (255, 0, 0) GREEN = (0, 255, 0) BLUE = (0, 0, 255)
Now we have colors defined, let’s start applying them.
Setting Up Game Display
Here is how to set up a game display of 800×600 pixels and set its background color to white.
DISPLAY = pygame.display.set_mode((800,600)) DISPLAY.fill(WHITE) pygame.display.update()
Our display window will now show as a white screen.
Drawing Shapes with Colors
Pygame provides us with a variety of shapes that we can draw on our screen, such as lines, rectangles, circles, and ellipses. Let’s start by drawing a red rectangle.
pygame.draw.rect(DISPLAY, RED, (200, 150, 100, 50)) pygame.display.update()
The rectangle will be drawn in the top left corner (200px from the left, 150px from the top), with a width of 100px and height of 50px.
Next, let’s draw a blue circle.
pygame.draw.circle(DISPLAY, BLUE, (400, 300), 50) pygame.display.update()
The circle will be drawn at the center of the screen with a radius of 50px.
Drawing Lines and Ellipses with Colors
After mastering the drawing of basic shapes, we can take a step further to create a line and an ellipse with specific colors.
The following code will draw a green line from point (100,100) to point (700,500):
pygame.draw.line(DISPLAY, GREEN, (100, 100), (700, 500), 5) pygame.display.update()
The last argument given in the function, ‘5’, denotes the width of the line.
Let’s not stop here! Let’s draw an ellipse. An ellipse requires a bit more information, including a rectangle that inscribes it. Let’s draw a red ellipse:
pygame.draw.ellipse(DISPLAY, RED, (350, 250, 200, 100)) pygame.display.update()
The first two arguments specify the top left corner of the rectangle, and the next two denote the width and height of the rectangle.
Update Display or Flip Display?
You might be wondering why we are calling pygame.display.update() after drawing each shape. Pygame uses a concept called ‘double-buffering’. What this means, in essence, is that Pygame works on two screens: one that is visible to us and one hidden ‘buffer’ screen.
When you create a shape in Pygame, it first gets drawn on this buffer screen. The pygame.display.update() or pygame.display.flip() is used to make all changes done in the buffer reflect on our visible screen.
Use the pygame.display.flip() command when you need to update the entire screen. But if you want up to update only part of the screen, use the pygame.display.update() function and pass the rectangle containing your objects as an argument.
pygame.display.update(pygame.Rect(200, 150, 100, 50))
With these examples in mind, you can now confidently start adding striking visuals to your game design. Creating engaging visuals with colors is one of the most exciting parts of game development! With Zenva, you’ll gain the knowledge and confidence to design and build your own spectacular games.
Adding Colors to Text
Adding color to text in your game can help with readability and help set the tone of your game. Pygame allows you to add colors to your text easily.
Here’s how you can create a red text:
FONT = pygame.font.Font('freesansbold.ttf', 32)
TEXT = FONT.render('Hello, World!', True, RED, WHITE)
TEXTRECT = TEXT.get_rect()
TEXTRECT.center = (400, 300)
DISPLAY.blit(TEXT, TEXTRECT)
pygame.display.update()In the above code, we first define a font object and then use the render method to create a text surface. The first argument is the text string, the second is a Boolean for antialiasing (smoothing the edges), then comes the text color and finally, the background color. The blit function is used to draw the text on the surface.
Changing Background Color with Events
Engage your users more by allowing them to control the color of the game background with user generated events. Below is an example of changing the background color when the user presses the SPACE key:
for event in pygame.event.get():
if event.type == KEYDOWN:
if event.key == K_SPACE:
DISPLAY.fill(BLUE)
pygame.display.update()This code awaits and checks for any key press event. If the key pressed is SPACE, it changes the background color to blue.
Fading Colors
A color fade effect can be used for transitions between scenes. Below, we’ll use a while loop to slowly change the color of a circle:
r = 255
while r > 0:
pygame.draw.circle(DISPLAY, (r, 0, 0), (400, 300), 50)
pygame.display.update()
r -= 1This is sure to keep your users hooked with dynamic visuals and prompt them to interact more with your game.
With these new skills at your disposal, we encourage you to try playing around with Pygame colors and explore the endless opportunities they present in enhancing your game’s visuals. Coding with colors is fun, and you’re just a few lines of code away from creating a vibrant, visually engaging game that excels not only in gameplay but also in aesthetics.
