yo, I need help w/ adding mobile support

this is my "main" file:

init = function() Camx = 0 Camy = 0

player = new player()

audio.playMusic( "bgm", 50, )

end

update = function() player.update()

Camx = Camx + (player.x - Camx) * 0.1 Camy = Camy + (player.y - Camy) * 0.1 end

draw = function() screen.clear() screen.setTranslation(-Camx, -Camy)

screen.drawMap( "world",0, 0,500,196 ) screen.drawMap( "desert",-500, 196,500,196 ) screen.drawMap( "world_2",500, 0,500,196 ) screen.drawMap( "world_3",500, -195.6,500,196 ) screen.drawMap( "world_4",0, -195.6,500,196 ) screen.drawMap( "world_5",0, 196,500,196 ) screen.drawMap( "world_6",500, 196,500,196 ) screen.drawMap( "desert",-500, 0,500,196 ) screen.drawMap( "desert",-500, -196,500,196 ) screen.drawMap( "desert",-500, -392,500,196 ) screen.drawMap( "desert_2",-1000, 0,500,196 ) screen.drawMap( "desert_2",-1500, 0,500,196 ) screen.drawMap( "desert_2",-1000, -196,500,196 ) screen.drawMap( "desert_2",-1500, -196,500,196 ) screen.drawMap( "desert_2",-1500, -392,500,196 ) screen.drawMap( "desert_3",-1000, -392,500,196 ) screen.drawMap( "desert_2",-1000, -588,500,196 ) screen.drawMap( "desert_2",-1500, -588,500,196 )

player.draw()

how do I add mobile support???
