Is there a way to handle collision detection between draw.circle and draw.rect ?
If I try to use sprite collision detection than it says circle has not got rect atrributes.
I create two players: rectangles. I create one ball: circle. I would like to handle the collision between two players and a ball in the best way possible. Could you help ?
I present my code below:
# DATE: 090215
TWO PLAYERS
CONTROL VIA KEYBOARD OR MOUSE
#
import pygame, sys
from pygame.constants import MOUSEMOTION, K_LEFT, K_RIGHT, K_DOWN, K_UP
pygame.init()
clock = pygame.time.Clock()
SCREENW = 800
SCREENH = 600
SCREEN = pygame.display.set_mode((SCREENW,SCREENH),0,32)
WHITE = (255,255,255)
BLACK = (0,0,0)
BLUE = (0,70,160)
RED = (255,0,0)
RECTH = 100
RECTW = 30
#players
PLAYER1P = (0,((SCREENH - RECTH)/2),RECTW,RECTH)
PLAYER2P = ((SCREENW-RECTW),((SCREENH - RECTH)/2),RECTW,RECTH)
# BALLS append with a ball for collision detection purposes
BALLS = []
# PLAYERS append with players for collision detection purposes
PLAYERS = []
# CLASS TO DEFINE PLAYER
class PlayerSprite(pygame.sprite.Sprite):
# define object atributes
def __init__(self,x,y,rwidth,rheight):
pygame.sprite.Sprite.__init__(self)
self.x = x
self.y = y
self.width = rwidth
self.height = rheight
# define object behavior
def update(self,control,Surface,color):
key = pygame.key.get_pressed()
self.control = control
if self.control == 1:
self.y = pygame.mouse.get_pos()[1]
if self.y >= SCREENH - RECTH:
self.y = SCREENH - RECTH
if self.control == 0:
dist = 20
if key[pygame.K_DOWN]:
self.y += dist
if key[pygame.K_UP]:
self.y -= dist
if key[pygame.K_LEFT]:
None
if key[pygame.K_RIGHT]:
None
if self.y >= SCREENH - RECTH:
self.y = SCREENH - RECTH
if self.y <= 0:
self.y = 0
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
# draw player as a rectangle
# the important bit is that here you can change player shape
self.player = pygame.Rect(self.x,self.y,self.width,self.height)
pygame.draw.rect(Surface,color,self.player)

self.x += self.speedx
self.y += self.speedy
# draw player as a rectangle
# the important bit is that here you can change player shape
pygame.draw.circle(Surface, color, (self.x, self.y), self.width, 0)
# main function
def main():
# CREATE PLAYER OBJECT before WHILE loop
prec1 = PlayerSprite(0,SCREENH/2 - RECTH/2,RECTW,RECTH)
prec2 = PlayerSprite(SCREENW - RECTW,SCREENH/2 - RECTH/2,RECTW,RECTH)

pygame.quit()
