I've been working on learning how to use SDL, by working through some of Marius' tutorials. However, in his third tutorial on using sprites, I'm having an issues. I've been pseudo-converting his code to valid C++ instead of C, and this loop is causing me a problem. It will run through 3 times, and then exit with a bus error. Does anyone have any idea why? If I don't comment out the else clause at the bottom, it will always exit with that error. Anyone have any ideas?
Thanks,
Spidy
