Use the camera.

In this I made a example for how to access the camera.
In this you can swap your face for a emoji!
This is one of my first projects so DONT expect the best and most efficient code

-- Use this function to perform your initial setup function setup() print("Hello World!") parameter.integer("WidthOfEmoji", 1, 10) parameter.integer("HeightOfEmoji", 1, 10) end -- This function gets called once every frame function draw() -- This sets a dark background color sprite(CAMERA,WIDTH/2,HEIGHT/2) -- This sets the line thickness strokeWidth(5) sprite("Project:Emoji1",CurrentTouch.x, CurrentTouch.y, WIDTH*WidthOfEmoji/10, HEIGHT*HeightOfEmoji/10) -- Do your drawing here end

Nice job!
