Need help with SDL mouse input
Author
I need help with SDL mouse input. I have been using "Focus on SDL" which is good, but is a bit lacking (or I'm just not seeing/understanding it) on how to get which mouse button was pushed and where. This is what I have now (note the fprint isn't long term needed, just nice to know it is working).
I think this is what you're looking after:
SDL_Event event;while (SDL_PollEvent(&event)) { switch (event.type) { case SDL_MOUSEBUTTONDOWN: switch (event.button.button) { case SDL_BUTTON_LEFT: printf("Left mouse button pressed.\n"); printf("At position %dx%d\n", event.button.x, event.button.y); // Get position of the button press break; case SDL_BUTTON_MIDDLE: printf("Middle mouse button pressed.\n"; break; case SDL_BUTTON_RIGHT: printf("Right mouse button pressed.\n"; break; default:break; } break; default:break; } }
I have a tutorial on that.
