Make a presentation with Python and Pygame<\/h1>\n

\"\"<\/a><\/p>\n

If you want to impress your audience you have to create something unique. You will use powerpoint? I do not think so. If you are a programmer, you want to use Python and if you want envolvment you will use the pygame libraries, right? Let’s dive into this project and show you a way, my own way, to do it, step by step.<\/p>\n

A long journey starts from a little step. (anonymous)<\/p>\n

First things first (the window)<\/h2>\n

The following code will make a window for you. Nothing in it, but you can close it.<\/p>\n

import pygame as pg\r\n\r\n# THE SCREEN SIZE AND DISPLAY + WINDOW NAME + CLOCK\r\ndef windowinit():\r\n\t\"\"\"Initialize the window with a way to quit it\"\"\"\r\n\tW, H = 800, 600\r\n\tdisplay = pg.display.set_mode((W, H))\r\n\tpg.display.set_caption(\"Mario Game\")\r\n\tclock = pg.time.Clock()\r\n\tcrashed = False\r\n\twhile not crashed:\r\n\t\tfor event in pg.event.get():\r\n\t\t\tif event.type == pg.QUIT:\r\n\t\t\t\tcrashed = True\r\n\t\tpg.display.update()\r\n\t\tclock.tick(60)\r\n\tpg.quit()\r\n\r\n\r\nif __name__ == \"__main__\":\r\n\twindowinit()<\/pre>\n
Let’s add some text to the window<\/h2>\n
Let’s create a class Text that displays the text of single objects<\/p>\n
class Text:\r\n\tdef __init__(self, screen, t, x=0, y=0, dim = 30, color=(0,0,0)):\r\n\t\tself.myfont = pg.font.SysFont(\"Comic sans MS\", dim)\r\n\t\tself.textsurface = self.myfont.render(t, False, color)\r\n\t\tscreen.blit(self.textsurface,(x,y))<\/pre>\n
In the function windowinit() we will create a list of string that will be our rows of text for each slide and then we will iterate the list with a for loop that will call for each string the class Text to render the text of the string in different positions (one under the previous).<\/p>\n
\ttextrows = [\r\n\t\t\t\t\"FULL COSTING\",\r\n\t\t\t\t\"Metodo per attribuire i costi ad\",\r\n\t\t\t\t\" un oggetto di calcolo (un prodotto).\",\r\n\t\t\t\t\" -------------------------\",\r\n\t\t\t\t\"Costi diretti + indiretti\",\r\n\t\t\t\t\"Costi diretti: facili da calcolare\",\r\n\t\t\t\t\"Costi indiretti:\",\r\n\t\t\t\t\"    sono comuni a pi\u00f9 oggetti di calcolo\"\r\n\t\t\t\t\" e quindi occorre dividere i\",\r\n\t\t\t\t\" costi comuni in base a dei criteri di riparto.\"\r\n\t\t\t\t]\r\n\tz = 0\r\n\tdim = 50\r\n\tfor row in textrows:\r\n\t\tif z==0:\r\n\t\t\ttextsurface = Text(screen, row, 0, z, 50, (0,255,0))\r\n\t\telse:\r\n\t\t\ttextsurface = Text(screen, row, 0, z, 50, (255,255,0))\r\n\t\tz += dim<\/pre>\n
The whole code will be this:<\/p>\n
