miniworlds#

miniworlds ist eine Spiele-Engine, geschrieben in Python (mit pygame). Sie ist dafür geeignet, dass Schüler einfache 2D Miniwelten und Spiele erstellen können.

Deine ersten Spiele mit miniworlds zu erstellen ist einfach!

Beispiele

Zwei tastaturgesteuerte Actors

from miniworlds import World, Actor

world = World()
world.add_background("images/grass.jpg")
player = Actor((90,90))
player.add_costume("images/player.png")
player.costume.orientation = -90
@player.register
def on_key_down_w(self):
    player.y = player.y - 1

player2 = Actor((180,180))
player2.add_costume("images/player.png")
player2.costume.orientation = -90
@player2.register
def on_key_pressed_s(self):
    player2.y = player2.y - 1

world.run()

Tontaubenschießen

Ein zufälliges Ziel kann mit der Maus “abgeschossen” werden.

from miniworlds import World, Actor, Number
import random

world = World(400, 400)
world.add_background("images/skeetshooting.png")
target = Actor((100, 100))
target.add_costume("images/target-red.png")
target.orientation = -90
target.size = (80,80)

cooldown = 5
hits = Number((20,20), 0)

@target.register
def act(self):
    global cooldown
    if self.world.frame % 50 == 0:
        target.position = (random.randint(0, 400), random.randint(0, 400))
    cooldown -= 1

@target.register
def on_clicked_left(self, position):
    global cooldown, hits
    if cooldown < 0:
        hits += 1
        cooldown = 10
        
world.run()

Flugzeuge

Ein klassisches Spiel, bei dem man ein Flugzeug steuert, dass Gegnern ausweicht und diese abschießen kann.
