is a fix32 positive only?

I am having problems with numbers less than zero in scrolling my road. It works fine scrolling right but when I scroll left and it gets below zero it turns to garbled gfx. Is fix32 positive only or perhaps the problem is with the fix32toint function? What other options are there?

Fix32 is signed but it all depends from your code implementation : having a single non signed comparison can make every thing wrong !

Good point. I'll take a closer look at my code. I could be using a u16 somewhere...

Found the culprit - my offset variable was a u16. Oops! All working now
