Instead, the whole layout is pushed up and you can't see the upper part of it. I tried many different keyboard spacer libraries but they all just push the TextInput even higher..

What is the best way to read input from keyboard using SDL?

由 邮差的信 提交于 2020-03-17 05:57:07
问题 I'm running an update() method n times per second to "update" the keyboard input from the user so I can read it later in the logic part of the program. So I find two ways of implementing this in the SDL Docs and I'm not sure which one should I use. 1; Loop for all events using SDL_PollEvent searching for key down/up events and saving the key states in a map so I can check for each key state in the logic of the program. Note: Alternatively, I can also use SDL_PeepEvents instead of SDL
