The Input object [E/M/W] The Input object allows you to retrieve input status. All keys will return a number; 0 when not pressed, 1 on the first frame the key is pressed, 2 while it's being held, and -1 on the first frame it's released. You can check if a key's value is greater than 0 to see if it's pressed, or if it's exactly 1/-1 to only have an action if it was just pressed/released. Possible key options are below.

Note: do not rely on the Input object to replace proper UI controls. Changing game state in the UI based on input will likely cause a fair share of issues and is not supported at this moment (but feel free to see what does and doesn't work).
