input handling:

App.map_key(:space, :jump) # maps the space key to a :jump action (multiple keys can be mapped to the same action)
# all events here are in english ones, (so need to find which english key corresponds to the key in the current language of the keyboard)
key can be one of [:a..:z, :0..:9, :space, :enter, :shift, :ctrl, :alt, :tab, :backspace, :escape, :up, :down, :left, :right, :middle]

this can be checked anywhere using:

App.down?(:jump) # returns true if the jump action is currently being pressed
App.pressed?(:jump) # returns true if the jump action was just pressed this frame
App.released?(:jump) # returns true if the jump action was just released this frame

for wheel, you can use:

App.wheel # returns a hash with :x and :y values representing the wheel movement since the last frame (can be used for zooming, scrolling, etc.)

mouse position can be accessed with:

App.mouse_position # returns a hash with :x and :y values representing the current mouse position in the window

For localized input, you can use:

App.start_text_input!

App.text_input # returns the text typed this frame as a string (useful for text input fields, chat, etc.)
               # can be multiple characters if the user types fast, so you should append it to a string variable to get the full input

App.stop_text_input!
