Title: Wavey Text

Author: Pete Shinners (pete at shinners.org)
Submission date: December 03, 2001

Description: Animated effect that deforms a text string along a sine wave.

Download: wavey.py

pygame version required: Any
SDL version required: Any
Python version required: Any

Comments: The code is quite clear; the example program continues animating the text until you click on the window - pressing 's' takes a screenshot.

example animated entry for the pygame text contest

if you would like to change this for your own entry, modify
the class so it returns the next image of the rendered text
each call to animate(). Note the image size should not change
for this simple framework.
import os, sys, math, pygame, pygame.font, pygame.image
from pygame.locals import *

class textWavey:
    def __init__(self, font, message, fontcolor, amount=10):
        self.base = font.render(message, 0, fontcolor)
        self.steps = range(0, self.base.get_width(), 2)
        self.amount = amount
        self.size = self.base.get_rect().inflate(0, amount).size
        self.offset = 0.0
    def animate(self):
        s = pygame.Surface(self.size)
        height = self.size[1]
        self.offset += 0.5
        for step in self.steps:
            src = Rect(step, 0, 2, height)
            dst = src.move(0, math.cos(self.offset + step*.02)*self.amount)
            s.blit(self.base, dst, src)
        return s

    renderer = textWavey(bigfont, entry_info, white, 16)
