Pygame Print Text Screen
I can't figure out to display text in pygame. I know I can't use print like in regular python IDLE but i dont know how import pygame, sys from pygame.locals import.
Now that you can create loops, it is time to move on to learning how to create graphics. This chapter covers: • How the computer handles x, y coordinates. It isn't like the coordinate system you learned in math class. • How to specify colors.

Up vote 2 down vote favorite. So I wanted to make my menu fade in when the game starts and fade out when it quits. To do so, I created a.
With millions of colors to choose from, telling the computer what color to use isn't as easy as just saying “red.” • How to open a blank window for drawing. Gangbusters Tsr. Every artist needs a canvas. • How to draw lines, rectangles, ellipses, and arcs. Video: The coordinate system for computer graphics The Cartesian coordinate system, shown in Figure (), is the system most people are used to when plotting graphics. This is the system taught in school.
The computer uses a similar, but somewhat different, coordinate system. Understanding why it is different requires a quick bit of computer history. Figure 5.1: Cartesian coordinate system During the early '80s, most computer systems were text-based and did not support graphics.
Figure () shows an early spreadsheet program run on an Apple ][ computer that was popular in the '80s. When positioning text on the screen, programmers started at the top calling it line 1. The screen continued down for 24 lines and across for 40 characters. Figure 5.2: Early Apple text screen Even with plain text, it was possible to make rudimentary graphics by just using characters on the keyboard.
See this kitten shown in Figure and look carefully at how it is drawn. When making this art, characters were still positioned starting with line 1 at the top. Figure 5.3: Text screen Later the character set was expanded to include boxes and other primitive drawing shapes. Characters could be drawn in different colors. As shown in Figure the graphics got more advanced. Search the web for “ASCII art” and many more examples can be found. Figure 5.4: Spaceware text screen Once computers moved to being able to control individual pixels for graphics, the text-based coordinate system stuck.
Figure 5. Tuxera Ntfs 2013.2 Keygen. 5: Computer coordinate system The $x$ coordinates work the same as the Cartesian coordinates system. But the $y$ coordinates are reversed. Rather than the zero $y$ coordinate at the bottom of the graph like in Cartesian graphics, the zero $y$ coordinate is at the top of the screen with the computer.
As the $y$ values go up, the computer coordinate position moved down the screen, just like lines of text rather than standard Cartesian graphics. Also, note the screen covers the lower right quadrant, where the Cartesian coordinate system usually focuses on the upper right quadrant. Sim City 3000 World Edition Completo Portugues there. It is possible to draw items at negative coordinates, but they will be drawn off-screen. This can be useful when part of a shape is off screen. The computer figures out what is off-screen and the programmer does not need to worry too much about it. Video: Opening a Window To make graphics easier to work with, we'll use “Pygame.” Pygame is a library of code other people have written, and makes it simple to: • Draw graphic shapes • Display bitmapped images • Animate • Interact with keyboard, mouse, and gamepad • Play sound • Detect when objects collide The first code a Pygame program needs to do is load and initialize the Pygame library. Every program that uses Pygame should start with these lines: # Import a library of functions called 'pygame' import pygame # Initialize the game engine pygame.init() If you haven't installed Pygame yet, directions for installing Pygame are available in the section.
If Pygame is not installed on your computer, you will get an error when trying to run import pygame. Don't name any file “pygame.py” Important: The import pygame looks for a library file named pygame. If a programmer creates a new program named pygame.py, the computer will import that file instead!
