This adds scrollx and scrolly support to mouse() for the mouse wheel information (horizontal/vertical).

Fixes #988

The following example is taken from @StinkerB06 cart for testing....

mouse.tic.zip

-- title:  Input reader
-- author: StinkerB06
-- input: mouse
function TIC()
	local x,y,left,right,middle,scrollx,scrolly=mouse()

	print("X: "..tostring(x), 1, 40, 4, 0, 2)
	print("left: "..tostring(left), 1, 60, 4, 0, 2)
	print("ScrollX: "..tostring(scrollx), 1, 80, 4, 0, 2)
	print("ScrollY: "..tostring(scrolly), 1, 100, 4, 0, 2)
end

Once merged, I can update the wiki documentation.

  1. Remember that the scroll values must be treated as two's complement numbers (-32 to +31).
  2. I think you should update the wiki's mouse() documentation when 0.80 comes out.

Remember that the scroll values must be treated as two's complement numbers (-32 to +31).

From my investigation, it was an integer from -1 to 1.
