General discussions / Re: SFML Game Development by Example - 4th SFML book
« on: December 20, 2017, 02:32:57 am »
I've been working through the book with a Mac and enjoying it quite a bit. There are a few roadblocks for Mac users, and so I thought I'd share the ones I've encountered so far to possibly spare others some pain.
- Make sure to use the ResourcePath helper function that comes with the OS X SFML installation whenever you need to load something from the file system (e.g. graphics, fonts, etc.)
- Earlier in this thread there is a discussion about errors caused by unordered_map and hashing custom objects. This applies to Xcode as well, and you will need to create and use the CustomHash header file as described.
- If you try to read in text files that come with the source code download, your code will throw a runtime error due to a null pointer (this first happens with keys.cfg in the EventManager and StateManager chapters). It took me forever to figure out that this appears to be due to the different end-of-line characters between Windows and OS X. A solution is to recreate the files on the Mac, I just typed them in using nano in a terminal window.
- More to come I'm sure!
