I haven't been able to test AppGameKit V2 with my project since it crashes when deleting sprites or text. I created a simple piece of code that replicates the problem. I attached the entire project here in a zip file. I will summit a bug report and link it back here.

It is tier 2. It is a Visual C++ 2010 project. I use 2013 IDE and have windows 8.1.

Thanks for any help.

Maybe you need to check if the objects exist, before you delete them?

I don't know about Tier2 and C++, but should not the variables be global type?

Technically, the variables you use should preferably be in template.h as either private or public members of the class.

Also as Impetus states, try a quick if sprite/text exists before deleting. However, i think that by putting the variables in the class declaration you are sure they assigned correctly in the class methods!

I think your variables are causing the issue!

The code looks fine. Checking to see if the objects exist is always a good idea, but the logic in the code shown is fine.

Impetus73, the variables as defined are global in the scope of that file.

I am wondering if the issue is with IDE 2013. AppGameKit was designed to work with VS 2008 or 2010. VS 2013 may be using libraries and headers and such that are not compatible.

Parry, I don't know if VS 2010 free is still available, but can you try installing that and seeing if you still have an issue?

This whole issue would go away if AppGameKit used Gnu C++ and didn't rely on the "free" versions of Visual Studio, with their frequent incompatible "updates" and "improvements."

-- Jim - When is there going to be a release?

I think using Visual Studio was chosen in part because it comes with all the Windows stuff built in. And it comes with a usable IDE to do stuff (including debugging).

I think there are Gnu C++ usable libraries and such for the I/O functions, but maybe there are issues with OpenGL. Don't know.

I'm just guessing about the reasons they chose it.
