Hi guys,

i am trying to implement a maze solver with a 3pi, i get an error: (identifier"simplify_path" is undefined) I am going to attach a pdf file with my code, can you please have a look at it and try to help me please??!!! i am struggling!!

In the PDF file i have higlighted the error in red, if i cancel simplify_path(); the error disappear but of course the whole program won't work as it's all the void functions are linked with each other./media/uploads/nepol77/maze_solver_c--.pdf

A text (as sourcecode is also just text) is read from top to bottom. So if you use a function before it is defined (or at least declared), you get this error
