Pathfinding algorithm wrote in C++ for python

pypath : A* pathfinding algorithm wrote in C++ for python

The goal of this project is to provide a fast and efficient python library that can find a path given a list of obstacle.

This module was originally developed for EIRBOT the robotic club of the engineer school Enseirb-Matmeca(French school).

REQUIREMENTS

You will need g++ in order to install pypath-fpa!

Avaliables constructors

• Coordinates(x,y)
• Size(width,height)
• Rectangle(Coordinates,Size)
• Castar()
• Field()
• Field(int robot_diameter)
• Field(int width, int height, int robot_diameter)

How to use

Here is a simple example :

    field = Field(20)
    castar = Castar()
    field.add_obstacle(Rectangle(Coordinates(60,20), Size(2,40)))
    field.add_obstacle(Rectangle(Coordinates(150,40), Size(10,40)))
    field.add_obstacle(Rectangle(Coordinates(80,80), Size(200,2)))
    err, path = castar.find_path_simplified(Coordinates(10,10), Coordinates(10,100), field)
    if err == 0:
        foo(path)
    field.delete_obstacle(Coordinates(10,40))

pypath's Issues

No path output

Hi,
Unfortunately I don't get any path data back when I run this code. What am I doing wrong?

thank you

Petop

`
from pypath import*

field = Field(width_mm=300,height_mm=300,robot_diameter_mm=30)

castar = Castar()

err, path = castar.find_path_simplified(start_coordinates=Coordinates(200,200), end_coordinates=Coordinates(50,50), field=field)

print (path)
print (err)
