Hi all,
Anybody knows how implement a graphical odometer with SDL, openGL,
etc ?
Or knows a link to a odometer component in C/C++ ?
Thanks

I've not done it myself, but I imagine that it's probably a simply
matter of determining a set of textures for the numbers, then the
space you want them to go, and finally keeping track of the distance
traveled, and cutting off the floating-point value, and then parsing
the integer into a string of numbers, and drawing those into their
appropriate locations using the appropriate number-texture. So, I
guess it comes down to how much OpenGL code do you know? (ie: can
you load textures and keep track of them?)
So IF you understand what I just rambled about (I'm REALLY bad at
explaining things to people), then maybe you can clarify at what
point you can no longer figure this out the rest of the way, and I
can try to give you some code. ^_^ I just don't want to teach/
exemplify stuff that you already know.
