Weird Errors

AmazingBKaiser (28)
Hello, I am writing an evolution simulator, but I recently came across a lot of error codes. The problem is that I don't even know what is wrong in my code. I have tried every thing and this is my last solution, else I might just abandon the project.
(I will upload the whole project to GitHub, user AmazingBKaiser and probably name it Creepie Crawlers, https://github.com/AmazingBKaiser/Creepie-Crawlers.git)


I got 20 errors so it would take too long to write the all down, but to summarize most of them were telling that the variable WorldTile was not defined (crawler.h l.19) or that Crawler wasn't a valid constructor (world.h l.23)

(I commented out most of the code just to see if the bug was there. It did decrease the number of error messages, but the error is probably not in World.cpp)

(left out Crawler.cpp because it was too long)

I got 20 errors so it would take too long to write the all down

You couldn't cut and paste from the compiler output window?
Because you didn't supply all the code, I can't compile it to duplicate your errors.

most of them were telling that the variable WorldTile was not defined (crawler.h l.19)

So where is WorldTile declared? You haven't posted a header declaring it.

It doesn't have a cpp file.

My German is rusty, but most of those errors are pretty obvious.

world.h line 23: Crawler is undefined. I do see that world.h includes crawler.h. Looking crawler.h line 5, you include world.h. This is a classic case of recursive includes. i.e. a.h includes b.h. b.h includes a.h.

Recursive defines should be avoided. Often creating recursive defines is just an oversight when not enough thought has been given to the class hierarchy.

However, there are cases where the are legitimate reasons for class A to reference class B and for class B to reference class A. If this is the case, the easiest way around this is to use a forward declaration for one of the classes. This means in the header (A) that has the forward declaration for B, B can only be passed by reference or as a pointer. It can not be passed by value since the compiler does not the size of B when it is declared forward.

Thanks very much. I would never have thought that the errors came from a case of recursive includes.
Thanks
