LightLogo (LLogo) aims to provide a simple, lightweight, and powerful 3D agent-based simulation toolkit for educational and scientific research.
pip install LightLogo
-
Redesigned turtle and more agent types that support 3D contexts;
-
Easy integration with Python and its massive Python libraries to enhance experience;
-
Following the basic principles of Logo language but with significant improvement.
Example 1: Playground
from lightlogo.play3D import *
clearscreen()
reset()
setxyz(5,-5,0)
pendown()
repeat(8,[
left(45),
fd(5)
])
penup()
repeat_play()Example 2: Full-scale agent-based simulation
from lightlogo.world3D import *
if __name__=="__main__":
# Step 1: Create a 3D world in LightLogo
w3d=world3D(x_range=[-10,10],y_range=[-10,10],z_range=[-10,10],title="Demo 2",)
w3d.create(style="seaborn-ticks")
# Step 2: Define an initialization function
def setup(world):
# create turtles
N=1
list_turtles=[
turtle3D(xyz=[0,0,0],color='red',shape='.',size=10) for _ in range(N)
]
list_turtles[0].left(45)
world.turtles(list_turtles)
# Step 3: Define a step function for each frame to update
def go(frame,world):
list_turtles=world.turtles()
print(f"Step {frame}\tTurtles Count: {len(list_turtles)}")
# turtle 1
turtle1=list_turtles[0]
if frame==0:
turtle1.pendown()
turtle1.forward(3)
# turtle1.setxrotate(45)
# turtle1.right(60)
# turtle1.up(45)
# turtle1.rollback(30)
# turtle1.setxrotate(45)
# turtle1.setxrotate(90)
if frame!=0 and frame % 1 == 0 and frame < 40:
turtle1.left(30)
t1=text3D(xyz=turtle1.pos(),color='green',text=f"p{frame}")
world.texts().append(t1)
if frame >=40:
turtle1.penup()
if frame>=10:
turtle1.hide()
if frame>=20:
turtle1.show()
list_turtles[0]=turtle1
world.turtles(list_turtles)
# Step 4 (final step): Run the simulation
w3d.run(go=go,setup=setup,interval=500,frames=1000,repeat=True)
