SDL disable keyboard and mouse input
Author
Im writing a simple game and at some point the user has a to move an object across the screen by first clicking the object and then clicking where they would like it placed, this part is working fine, what i want to be able to do is disable all input from the mouse and keyboard while the object is moving. Any help is appreciated.

Ok, i have sorted out the mouse by using SDL_ShowCursor(SDL_DISABLE) but what about keyboard?
Yeah, this is just a programming problem, not specifically SDL. Just use a test for your condition like so:
Note that you still need to poll the events, so that you actually discard them. Otherwise, the event queue will fill up and you'll get weird results. Using SDL_ShowCursor(SDL_DISABLE) will hide the mouse cursor, but does not stop events. It is useful when you want to display your own cursor (image) rather than the default one.
SDL_Event event;bool done = false;while(!done){ while(PollEvent(&event)) { if(event.type == SDL_QUIT) done = true; if(objectIsMoving) { // Keyboard and mouse input stuff here } } // Drawing, updating, etc.}Note that you still need to poll the events, so that you actually discard them.
