Need help math.randomseed

Hello I am new to codea as well as coding I am trying to make a game similar to bit invader only horizontal. So far I have created a spaceship sprite which is movable as well as a background with some stars.

-- Use this function to perform your initial setup
function setup()
x = WIDTH/2
y = HEIGHT/2
c = color(0, 0, 0, 255)
end

-- This function gets called once every frame
function draw()
background(0, 0, 0, 225)

sprite("SpaceCute:Star",374,374)
sprite("SpaceCute:Star",100,150)
sprite("SpaceCute:Star",400,550)
sprite("SpaceCute:Star",600,200)
sprite("SpaceCute:Star",150,650)
sprite("SpaceCute:Star",650,700)
sprite("SpaceCute:Rocketship",150,y)
end

function touched(touch)
x = x
y = touch.y
end

I am looking to have objects come on to the screen horizontally and have you control the spaceship to avoid them. However I am a stuck at how to get the objects to come onto the screen infinitely and how to get them to come on at random points in the right hand side. I believe you use something called math.random seed then enter coordinates. For example, (math.randomseed1,100) and then it will randomly chose between the 1 and 100 coordinates to come on. Deos anyone know how to apply this to my game. Please keep it as simple as possible and any help is greatly appreciated.

I added some code to your program to just give you an idea of what you can do. Youâ€™ll have to use a table to have multiple objects going at once. If you have questions, just ask.

function setup()
displayMode(FULLSCREEN)

x = WIDTH/2
y = HEIGHT/2
c = color(0, 0, 0, 255)

x1=0
y1=0
end

function draw()
background(0, 0, 0, 225)

x1=x1-5
if x1<1 then
rand()
end

sprite("SpaceCute:Star",x1,y1)    -- change x1 and y1 to use a table

sprite("SpaceCute:Star",100,150)
sprite("SpaceCute:Star",400,550)
sprite("SpaceCute:Star",600,200)
sprite("SpaceCute:Star",150,650)
sprite("SpaceCute:Star",650,700)

sprite("SpaceCute:Rocketship",150,y)
end

function touched(touch)
x = x y = touch.y
end

function rand()
y1=math.random(50,HEIGHT-50)
x1=WIDTH
end

Good stuff guys. Thanks for sharing.

thanks dave, very helpful, just got to figure out collision then I am done.
