Rendering a texture with SDL2 causes “Invalid texture” error message

No Comments on Rendering a texture with SDL2 causes “Invalid texture” error message

When SDL_RenderCopy() gets called, it fails and SDL_GetError()returns the error "Invalid texture". Here’s my code: main.cpp #include "Game.cpp" #include <iostream> using namespace std; int main(int argc, char* args[]) { try { Game game("Test", 1280, 720, 60); GameObject object("Immagine.bmp"); game.addObject(object); game.run(); } catch(const char* message) { cerr<<message; } return 0; } Game.cpp #include "GameGraphics.cpp" class Game […]

Tags "resources/images/"); surface = SDL_LoadBMP(strcat(basePath, 0); if(window == NULL) { throw SDL_GetError(); } renderer = SDL_CreateRenderer(window, 1, 1280), 60); GameObject object("Immagine.bmp"); game.addObject(object); game.run(); } catch(const char* message) {, 720, as if I was passing it by value). So when the texture member of object is modified, bmpFile)); if(surface == NULL) { throw SDL_GetError(); } texture = NULL; }, char* args[]) { try { Game game("Test", height, I'm just modifying the copy, int height, int targetFps) { if(SDL_WasInit(SDL_INIT_EVERYTHING) < 0) { throw "Can't construct GameGraphics object without, int targetFps) { running = false; if(SDL_Init(SDL_INIT_EVERYTHING) != 0) { throw SDL_GetError();, int width, it fails and SDL_GetError()returns the error "Invalid texture". Here's my code: main.cpp #include "Game.cpp" #include using na, it gets a NULL instead of a pointer to the texture to render, java, Javascript/Typescript) and I think I might be getting something wrong about the mechanism of passing an object by reference. What I suspect t, not a reference to an external object. So when SDL_RenderCopy() gets invoked (inside GameGraphics::render()), null, NULL) == -1) { throw SDL_GetError(); } } SDL_RenderPresent(renderer); }, object.getSurface()); if(texture == NULL) { throw SDL_GetError(); } object, object.getTexture(), Python, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC); if(renderer == NULL) { SDL_DestroyWindow(window);, SDL_WINDOWPOS_CENTERED, targetFps); } catch(const char* message) { SDL_Quit(); throw; }, therefore the error gets printed. But according to countless sources I've read through the last few hours, this is the correct way to pass an object by reference. What am I getting wrong then?, ticksPerFrame; SDL_Renderer* renderer; SDL_Window* window; public: GameGraphics(const char* title, When SDL_RenderCopy() gets called, width

No Comments on Diff a tarball on stdin against a directory hierarchy?

I have a multi-terabyte filesystem I want to diff against a multi-terabyte tar file. The tar file is only available from stdin – no seeking allowed. I do not have the disk space to write the tar on stdin to disk. "tar –diff" is almost what I want, except: It does not allow comparing mtime’s […]

Tags and did find several almost-solutions, but nothing precisely like what I'm looking for. Thanks!, c--, C++ or Go - in that order. I googled this for about an hour, except: It does not allow comparing mtime's within a tolerance - some of the mtimes in the tarball are rounded. It'd be better to ignore mti, I have a multi-terabyte filesystem I want to diff against a multi-terabyte tar file. The tar file is only available from stdin - no seeking a, is something like this already available? I'd prefer a solution in Python, java, Rust
