Form Code, and Squishing

I got squishing working! The White box (which will soon be replaced with actual sprites) can now detect being squished vertically or horizontally, and call a script.

In other news, I've started implementing actual graphics for the levels. How I'm doing it, is each feature will have a string identifying its style. The styles are stored in structs like the following:

struct FeatureStyle

{

SDL_Surface* surface_;

FeatureStyleMode mode_;

SDL_Rect middle_;

SDL_Rect left_edge_;

SDL_Rect top_left_corner_;

SDL_Rect top_edge_;

SDL_Rect top_right_corner_;

SDL_Rect right_edge_;

SDL_Rect bottom_right_corner_;

SDL_Rect bottom_edge_;

SDL_Rect bottom_left_corner_;

};

The mode_  simply defined if its just one, tiles, or tiled with borders. The SDL_Rects define where each part of the image is. The problem is, that this has just led to the biggest piece of copy-paste form-code in my recent history. I've been discussing over at StackOverflow whether there is a better way . There is a good chance I'll implement Konrad Rudolf's excellent suggestion. You can find the discussion on http://stackoverflow.com/questions/9260911/avoiding-copy-paste-code-initialising-a-series-of-sdl-rects-in-a-struct/9261170#9261170 if you feel like contribution. It follows, unadulterated.
