Hello, I'm trying to get the map1 bitmap value to be different images depending on what mapnum value is passed to it.
Thank you so much.Code:world_map2::world_map2(int mapnum) { map1=load_bitmap("images/maps/planet1.bmp", NULL); }

Wouldn't you need some type of arguments to do this?
if mapnum ==1 load this // if mapnum==2 load that.
Or, perhaps something funky and make your mapnum a string rather than an int. Doesn't matter what the character contained within the string is.
I'm not sure if that'd work for you or not.Code:#include <iostream> #include <string> std::string get_number; void funky(std::string number) { std::string test="images/maps/planet"; test.append(number); test.append(".bmp"); std::cout<<test; } int main () { std::cout<<" enter a number: "; std::cin>>get_number; funky(get_number); std::cin.ignore(); std::cin.get(); return 0; }

well, if you need to add bitmaps at runtime, I'd use an std::map.
if not, then just hardcode an arrayCode:std::map<int, std::string> bitmaps; bitmaps[0] = "bmp1"; bitmaps[1] = "bmp2"; world_map2::world_map2(int mapnum) { map1=load_bitmap(bitmaps[mapnum], NULL); }
Code:static const char* bitmaps[] = { "images/maps/planet1.bmp", "images/maps/planetoftheapes.bmp", "images/maps/hoth.bmp", "images/maps/magarathea.bmp", "images/maps/uranus.bmp" // heh heh }; world_map2::world_map2(int mapnum) { map1=load_bitmap(bitmaps[mapnum], NULL); }

If you program in C++, you need Boost. You should also know how to use the Standard Library (STL). Want to make games? After reading this, I don't like WxWidgets anymore. Want to add some scripting to your App?
