That's a good idea. I figured I'd do the nitty gritty stuff eventually, just wanted to see if anyone had any insight as to what I might be doing wrong.

The #ifdef USE_SDL idea is a great tip and also something worth including in future code so I can just swap between console and graphics libraries to see that the gears are in fact turning the way I want them to.

Thanks again! 8]

- Yes (hence the part where I stated that I can see that the vector class' variables aren't being assigned any values)

I've already tried to debug it to the extent that I can (usually with somewhat greater success). My question is basically why making a single struct works with all the function calls whilst when defining an array of the same structs it does not, even though I am referencing them as single values, array[0], array[1], in the same manner as I would if they were single variables.

Thanks for the reply btw!

Ooooo, thanks to the logcat trick I actually managed to fix it myself.

The problem was actually really simple. For some reason my graphical layout editor wasnt saving the XML properly and thus the NullPointerException came from referencing stuff in the XML that wasnt actually there, so I remade it and now it works like a charm!

Sorry for posting and then figuring it out on my own..

Thanks for the tip, edited my previous post so you can see what logcat gave me.

Thanks, sorry about posting in the wrong part of the forum, thought I actually had the right one.
