  1. POmaking bouncing pacman with pygame mode change bugging out
    text
    copied!<p>RANDOM PACMAN The task was to animate 5 objects(pac man and 4 ghosts that moved randomly,if pac man collides with a ghost he bounce's off it, the ghosts pass though one another and are unaffected when hit by pac man. When the mouse is clicked the mode changes and the ghosts bounce of pac man if they collide and pac man is unaffected, if the mouse is clicked again it reverts back to the original mode. Functions ghost_collision and mode_swich deal with this and I have a if statement at the end for the mouse click. BUG1I can't work out why when sprites collide sometimes they become immobile (in both modes). Also is I possible to replace some of the repeated if statements with a list and a for loop? If so how? I tried making a list of all the ghost_boundary variables and then using </p> <pre><code> For sprite in sprite_list(): sprite.left &lt; 0 or sprite.right &gt; WIDTH: sprite_velocity[1] = -1 * sprite_velocity[1] </code></pre> <p>and that failed.</p> <pre><code>import pygame from random import * pygame.init() def ghost_collision(): # global pacman_up, pacman_right, pacman_velocity why?
