Yuuup, looking for a good example.
Okay 
(No idea why Iâm doing the laugghing smiley)
Hello are you there now?
Still playing - back shortly.
Edit : Still fiddling with my simple demo, in the meantime here is a simple demo from the Ignatz site - hope this helps.
Oh thanks!!!
you very muvh
@Bri_G Actually, I wanted to have a button all the time (e.g.), and when I click on it, a new window opens, so to speak, and then I can âinâ things myself and you can also close the "windowâ
I made this code myself. But there is a problem. So the texts and so are in German, but if you click on the âCotton redâ and you move your finger except the if then the green background is gone. Is it possible to remove it?
@Killer.Jo - actually reading this from images is very difficult. A lot of the code seems to be missing. To get the best from posting code you need to post it as preformatted text. Look at the forum editing window bar, there is a settings gear at the right. Tap that and you get a list of options of which the top one is âpreformatted textâ when you tap that three lines are added to the editing window the top and bottomones are there as delimetters for your code. The centre line reads âpreformatted textâ and is highlighted.
Select an copy your code from Codea andtap on the highlighted text in the forum edit window and it will paste in your code. Exit edit and press reply and the code is then available to forum members to easily copy and use.
Edit: your formatting seems to have infected my post - both narrow width !!!
Edit 2: Closed forum and reopened and formatting OK now !!!

Ah good!!! I hope youâre not overwhelmed because that might be a lot of work. And by the way: I write all this with translator
@Killer.Jo - played around with your code. I think you misunderstood the basics of Codea. You donât need to put massive code in the draw() function. You need to capture touch events and change variables which you then use in draw(). Also setting up variables etc in Setup() can simplify and help you understand what you need. Setting up variables with a relevant name is easier to understand than numbers.
Code is here:
-- Killer.jo
viewer.mode = FULLSCREEN
viewer.retainedBacking = true
function setup()
--
-- sprite definitions
planet = asset.builtin.SpaceCute.Planet
pw, ph = spriteSize(planet)
red = asset.builtin.Blocks.Cotton_Red
grass = asset.builtin.Blocks.Grass3
ship = asset.builtin.Space_Art.Green_Ship
prt = ""
fcol = color(67, 236, 82)
txt1 = "Wird zerstör"
txt2 = "Bombe wird plaziert"
txt3 = "NĂ€chster Planet"
txt4 = "Bombe plaziert"
midX, midY = WIDTH//2, HEIGHT//2
planetPos = vec2(midX, midY)
msgPos = vec2(midX,HEIGHT-60)
planetSize = 200
planetRad = planetSize//2
startPos = vec2(200,200)
buttonPos = vec2(planetPos.x+150, planetPos.y+200)
buttonSize = 100
shipPos = startPos
end
function draw()
--
background(0)
pushMatrix()
spriteMode(CENTER)
sprite(planet, midX, midY, pw, ph)
sprite(ship,shipPos.x, shipPos.y, 100, 100)
sprite(red, buttonPos.x, buttonPos.y, buttonSize, buttonSize)
textMode(CENTER)
fill(fcol)
font("Baskerville-BoldItalic")
fontSize(32)
text(prt,msgPos.x, msgPos.y)
popMatrix()
end
function touched(t)
--
if t.state == BEGAN or t.state == MOVING then
shipPos = t.pos
if inCircle(t.pos, planetPos, planetRad) then
if t.state ~= ENDED then
fcol = color(255, 0, 45)
prt = "Over The Planet Drop Bomb !!"
end
else
fcol = color(67, 236, 82)
prt = "Outside the planet"
end
end
end
function inCircle(p, c, r)
-- p is the point, c is the center of the circle, and r is the radius
print(p,c,r)
local dist = math.sqrt((p.x - c.x)^2 + (p.y - c.y)^2)
if dist < planetSize then return true else return false end
end
As you can see you can write text dialogue outside the reformatted text.
I wasnât sure what you was trying to achieve so you may need to modify this code a lot.
I added a inCircle() function to avoid lots of numbers in comparisons. Not, the planet sprite is not a circle as you can see in the values of pw, ph but the code roughly shows how it works.
So in summary, set up variables in Setup(), capture touch events in touched() and modify variables then use draw() to generate your screen
Hope that helps.
Edit: As you grow to understand the structured approach you will introduce more external functions to carry out small features of code, generally repetitive code.
@Bri_G Yes, thank you very much, But actually I meant that when I due sprite âasset.builtin.Blocks.Cotton_Redâ then comes a green background. But if you click somewhere again, the green background is gone. And I want to avoid that. Can you give me an improved code? 
@Killer.Jo - OK, try this
viewer.mode = FULLSCREEN
viewer.retainedBacking = true
function setup()

planet = readImage(asset.builtin.SpaceCute.Planet)
pw, ph = spriteSize(planet)

tcol = color(0, 233, 255)
bkgnd = color(67, 236, 82)
txt1 = "Wird zerstör"
txt2 = "Bombe wird plaziert"
txt3 = "NĂ€chster Planet"
txt4 = "Bombe plaziert"
midX, midY = WIDTH//2, HEIGHT//2
planetPos = vec2(midX, midY)
msgPos = vec2(midX,HEIGHT-60)
planetSize = 200

startPos = vec2(200,200)
buttonPos = vec2(planetPos.x+150, planetPos.y+200)
buttonSize = 100
buttonRad = buttonSize//2
shipPos = startPos
zapped = false
end
function draw()
--
if zapped == false then
background(0)
else
background(bkgnd)
end
pushMatrix()

if zapped == false then
sprite(planet, midX, midY, pw, ph)
end
sprite(ship,shipPos.x, shipPos.y, 100, 100)
sprite(button, buttonPos.x, buttonPos.y, buttonSize, buttonSize)
textMode(CENTER)
font("Baskerville-BoldItalic")
fontSize(32)
text(prt,msgPos.x, msgPos.y)
popMatrix()
end
function touched(t)
--
if t.state == BEGAN or t.state == MOVING then
touchPos = t.pos
if inCircle(t.pos, buttonPos, buttonRad) then
fill(tcol)
prt = "Kaaaaboooom !!!"
zapped = true
elseif inCircle(t.pos, planetPos, planetRad) then
shipPos = touchPos
if t.state ~= ENDED then
fill(fcol)
prt = "Over The Planet Drop Bomb !!"
end
else
shipPos = touchPos
fill(tcol)
prt = "Outside the planet"
end
end
end
function inCircle(p, c, r)
-- p is the point, c is the center of the circle, and r is the radius
print(p,c,r)
local dist = math.sqrt((p.x - c.x)^2 + (p.y - c.y)^2)
if dist < planetSize then return true else return false end
end
Edit: Updated the code to make the project do what I think you wanted and took out my own mistakes. Hope this meets your needsâŠ

Thannnnnnnkssssss!!!
Can you make a simple game with a main menu with several buttons and when you click on one come more buttons and there is a back button that you come back to the main menu. I think at least then, have you FINALLY solved my problem that would be the best moment of my life (in programming) then I will FINALLY write you other things in Codea talk then you have also done so much for me you can then rest from me 
and I know that this is a lot of work I hope that you forgive me
@Killer.Jo - OK, here is what I think you asked for. Now Iâm going to get stuck into my own project. When youâve finished post your project so we can see how well youâve done.
viewer.mode = FULLSCREEN
function setup()
--
midX, midY = WIDTH//2, HEIGHT//2
buttonMaster = asset.builtin.UI.Blue_Box_Tick
masterPos = vec2(midX, midY)
returnPos = masterPos
buttons = {
asset.builtin.UI.Green_Box_Tick,
asset.builtin.UI.Grey_Box_Tick,
asset.builtin.UI.Red_Box_Tick,
asset.builtin.UI.Yellow_Box_Tick,
asset.builtin.UI.Blue_Circle
}
butSize = 80
butRad = butSize//2
chosen = false
mode = "start"
str = "Option not chosen yet"
end
function draw()
--
background(19, 19, 23)
if mode == "start" then
pushMatrix()
spriteMode(CENTER)
sprite(buttonMaster, midX,midY, butSize, butSize)
elseif mode == "options" then
for lp = 1, 4 do
sprite(buttons[lp],lp*160, 800, butSize, butSize)
end
ret = #buttons
fill(67, 236, 71)
font("Arial-BoldItalicMT")
fontSize(48)
text(str, midX, HEIGHT-60)
sprite(buttons[ret],midX, midY, butSize, butSize)
popMatrix()
end
end
function touched(t)
--
if t.state == BEGAN then
myTouch = t.pos
if mode == "start" and inCircle(myTouch, masterPos, butSize//2) then
mode = "options"
elseif mode == "options" and inCircle(myTouch, returnPos, butSize) then
mode = "start"
else
for lp = 1, 4 do
if inCircle(myTouch, vec2(lp*160,800), butRad) then
chosen = "true"
str = "Button pressed is : " .. lp
end
end
end
end
end
function inCircle(p, c, r)
-- p is the point, c is the center of the circle, and r is the radius
local dist = math.sqrt((p.x - c.x)^2 + (p.y - c.y)^2)
if dist < butRad then return true else return false end
end
Okay, wait a few days and then maybe Iâll be done
How can I make even more buttons and how can I make a different execution instead of a text (I know that Iâm a complete beginner, I just donât understand all thisđ„Č)
