If you have 'r' mapped to the reload action, you might want 'r' to reload regardless of whether shift or capslock is held down. In that case it's easy to add 'R' also mapped to the reload action. It seems like for key bindings, you're either binding positionally, in which case ...
The keysym approach detected the key being pressed, but my own function relying on SDL_GetKeyboardState, for those 7 frames of me holding the key down, reported as NEVER HELD, essentially proving that the state isn't being updated correctly. This only occurs until a couple seconds after my...
