Hello! I am looking for some help, and have provided the code. I'm just trying to do some simple stuff. I'm trying to create a simple game without using classes (but using lists).
What I'm trying to do is create collision detection among list objects ("bullets" and "baddies"), as you'll be able to see in the code.
I'm also trying to fire 10 bullets at once from an "ammoCrate". My problem is that I have to stay on the "ammoCrate" in order for the bullets to do their thing, otherwise they stop in place and disappear, but continue if the "playerRect" stays on the "ammoCrate". Additionally, I'm firing the bullets from a given position, and not from the "ammoCrate" that the "playerRect" is touching/colliding with. NOTE: I'm using primitives instead of loaded images. Here is the code:
import pygame, sys, time, random
from pygame.locals import *
pygame.init()
def collision(playerRect,baddies,baddiesA):
for b in baddies:
if playerRect.colliderect(b):
return True
for bA in baddiesA:
if playerRect.colliderect(bA):
return True
return False
def bulletCollide(bullets,baddies,baddiesA):
for b in baddies:#lists will not collide?
if bullets.colliderect(b):
baddies.remove(b)
for bA in baddiesA:
if bullets.colliderect(bA):
baddiesA.remove(bA)
def ammoCollide(playerRect,ammoCrate):
for x in ammoCrate[:]:
if playerRect.colliderect(x):
#if ammoCrate.remove(x), the bullets cease bc the cmd is complete. Cmd must keep going.
for i in range(len(bullets)):
pygame.draw.rect(screen,WHITE,bullets[i])
for i in bullets[0:0]:
i.move_ip(2,-2)
for i in bullets[0:1]:
i.move_ip(2,2)
for i in bullets[1:2]:
i.move_ip(0,2)
for i in bullets[2:3]:
i.move_ip(2,0)
for i in bullets[3:4]:
i.move_ip(4,-4)
for i in bullets[4:5]:
i.move_ip(-4,4)
for i in bullets[5:6]:
i.move_ip(-2,2)
for i in bullets[6:7]:
i.move_ip(4,4)
for i in bullets[7:8]:
i.move_ip(6,-6)
for i in bullets[8:9]:
i.move_ip(-6,6)
for i in bullets[9:10]:
i.move_ip(6,6)
bulletCollide(bullets,baddies,baddiesA)
