graphics tablet

Post by GVovkiv »

Soo, apparently love doesnt have support of graphics tablets?
Like detecting if tablet connected or pressure, etc?

P.S:
Well, as Alex said on GitHub, i guess there will no proper support for tablets unless SDL will have it
Sadly

It can be also for the tablets, you get some pen-touches here.

Code: Select all

function love.draw()
	local touches = love.touch.getTouches( )
	for i, id in pairs (touches) do
		local pressure = love.touch.getPressure( id )
		love.graphics.print('i: '..i..' pressure: '..pressure, 32, 32+20*i)
	end
end

The Huion Inspiroy H430P looks like an alternative for a mouse input; so more like a graphics tablet than a tablet computer. Try https://love2d.org/wiki/love.mouse.isDown and https://love2d.org/wiki/love.mouse.getPosition.

It's an alternative for mouse input, yes, like all other graphics tablets. So while you can track them with love.mouse functions, I don't think there's any functionality in löve to detect pressure of the pen touches if love.touch.getPressure doesn't work. Not sure how you would go about it with Huion tablets, but Wacom tablets provide an API that you could hook up to with C, and then from where with luajit. Maybe Huion might have similar opportunity.

I've tried this code (touch-pressure-01.love) with Wacom Bamboo Fun Pen & Touch, it feels like a mouse click, the pressure is always 1 (Wacom Bamboo Fun Pen & Touch supports pressure, the pen with 1024 levels of pressure sensitivity).
