In the constructor, it fails to compile at the setSkin function/method. The errors are: What am I missing? I see no reason for it to not find it, I've included the necessary header files.

Need to see more code. Probly a missing semicolon at a class ending or circular includes, or some such oddity.

I updated the first post, copy pasted the header files and cpp files. Edit: I found the problem, it was circular includes.

Yeah, there it is. tower.h includes entity.h which includes tower.h, so on.... entity.h doesnb't need the include to tower.h there. A base class rarely needs to know about derived classes, if it does, it uses pointers to itself usually... anyway, done rambling now.... tile.h said: #include "TowerManger.h" Misspelled Manager there... Otherwise, it looks okay. My Website! | EAGLE GUI Library Demos | My Deviant Art Gallery | Spiraloid Preview | A4 FontMaker | Skyline!

Hmm can't tell which is right anymore, don't know that one. The second one looks like Miss Pell. She's hot.
