Bug in dx/dy for multi touch on Android (DEF-1726)(SOLVEDx3)

So, I’ve come to using this module and I’m not sure how! I get screen coordinates from input, but then what? This doesn’t work (the node is moved outside the screen area):

Are you sure you added changes into your render_script?

@AGulev

First of all, we need to recalculate all coefficient when you change screen size, that why we need to add a few lines into render_script :

-- require the module
local gui_extra_functions = require "gui_extra_functions.gui_extra_functions"
...
function init(self)
  ...
  -- calculate coefficients when init the game
  gui_extra_functions.update_coef(render.get_window_width(), render.get_window_height())
end
...

function on_message(self, message_id, message)
  ...
  -- calculate coefficients when changing screen size
elseif message_id == hash("window_resized") then
  gui_extra_functions.update_coef(render.get_window_width(), render.get_window_height())
elseif
...
end
