Movement

Movement#

In diesem Kapitel setzen wir Elemente in Bewegung. Dabei helfen uns auch Variablen.

Simple Bewegungen#

You can achieve a simple movement by changing the x and y attributes of an object.

from miniworlds import *
import random
world = World((100,100))
c = Circle((0,50), 20)
@world.register
def act(self):
    c.x = c.x + 1
    
world.run()

Output:

bewegen

Der Modulo-Operator#

The modulo operator is particularly helpful for repetitive movements.

Python kennt 3 Arten von Divisionen:

13 / 3 liefert das Ergebnis 4.3333333333 13 // 3 liefert das ganzzahlige Ergebnis 4 13 % 3 liefert den Rest der Division 13 / 3, also 1 zurück.

That the remainder can never be greater than the dividend can help us with animations:

from miniworlds import *
import random
world = World((100,100))
c = Circle((0,50), 20)
x = 0
@world.register
def act(self):
    global x
    c.x = x % 100
    x = x + 1
world.run()

The variable x keeps counting upwards, since the remainder of the division of x and 100 can never be greater than 100, the point moves back again.
