This is a simple navigation system I wrote.
The "else" in check_if_end() is supposed to be find_path() but I was just testing so it looked like what we currently see.
I arranged the system in triangle , each area intersects with the other two.
Area 1 is set to be start point
Area 3 is set to be the end
According to the code this should print
Area 2 , 1 , [area 1 , area2]
Area 3 , 1 , [area1 , area3]
But instead we get this
Area 2 , 1 , [area 1 , area2]
Area 3 , 1 , [area1 , area2 , area3]
Seems like the if-else in check_if_end() is not working properly.
When I detete total_path.append(self) in the else section, everything works fine.
we get what we expected like
Area 2 , 1 , [area 1]
Area 3 , 1 , [area1 , area3]
I don't know why this is happening plz help me :(
