If I re-size the window bigger, the x,y positions from either mouse events, seem to be restricted to the original window Width and Height. If there some function call that I'm missing to tell SDL that the mousing area has increased in size. The relevant parts of the app: void Resize ( int width , int height ) { WindowWidth = width ; WindowHeight = height ; /* update OpenGL */ } void Init () { glClearColor ( 0.f , 0.f , 0.f , 1.f ); Resize ( WindowWidth ,

I can see a Metadata property that contains a string of XML, and a MetadataSchema property that represents a link to a Schema. Should I deal directly with the XML, or is there a way to do something more like the ItemFields processing in the TOM.Net? What if I want to add metadata to an item that doesn't already have any set? 回答1: You'll need to provide your own code to parse and modify that XML, based

Basically I can't seem to be able to compile a basic Hello World program on OSX (Yosemite) using the SDL2 external library. I'm trying to do this on console, without the help of any IDEs. I already installed the SDL 2.0.3 and it is located on the /Library/Frameworks/SDL2.framework path. My main file looks like this: #include <SDL2/SDL.h> #include <stdio.h> bool init(); void close(); SDL_Window* gameWindow = NULL; SDL_Surface* gameScreenSurface = NULL; bool init() { ... } void close() { ... } int main( int argc

For example I have the blue rectangle texture, and I want to draw red rectangles on top of this blue rect. However i want them to restrict the render only on this rectangle. Like the following image: I read something about texture blit between them or something like that but im not sure if this is posible. My code looks like this: SDL_RenderCopy(ren,bluetexture,NULL,dBLUErect); SDL_RenderCopy(ren,redtexture,NULL

I have little to no experience when it comes to compiling/building anything, especially when Code::Blocks doesn't use makefiles. I downloaded SDL2-devel-2.0.0-mingw.tar.gz (SDL Development Libraries) from http://www.libsdl.org/tmp/download-2.0.php , and I'd like to create a standalone executable using SDL2 libraries, but so far I've always had to bundle the SDL2.dll file with the executable to make it work. I've heard that I can not static-link dynamic libraries, so my only option seems to be

I was following introductory examples (from lazyfoo mostly) and made a simple test. #include <stdio.h> #include <SDL.h> const int SCREEN_WIDTH = 640; const int SCREEN_HEIGHT = 480; int main(int argc, char const *argv[]) { /* The window handle */ SDL_Window* window = NULL; /* The surface contained in the window */ SDL_Surface* screen_surface = NULL; /* Init SDL */ if(SDL_Init(SDL_INIT_VIDEO) < 0) { printf("SDL could not initialize!
