If and else statement

Questions
21

Ok thanks
Can I use this to learn and make games?

22

@Gamerage13 As far as I’m concerned, anything posted on this forum can be used by anyone. It would be nice to acknowledge if you use someone else’s code though.

23

A loot of this is my experience cause JavaScript and lua are
Almost the same :slight_smile:

And you helped me with one thing and I learned how to write an if and else statement
Thanks to the forum and other people.

And yes I’m using a little bit from some examples in the codea app
I’m only using it now beacuse I’m still learning lua.
And I et some code frome the forum
Cause I’m a beginner in lua
And much of things I Learned am I using in other projects

@Gamerage13 It good that you’re learning. A lot of people give up because they say it’s too hard. Don’t think that you ask too many questions because that’s what a lot of us are here for, to help others. Anytime you have a question, just ask. Just make sure you include enough information. The more you include, the easier it is to answer.

@Gamerage13 - I’ve written a lot of stuff that may help you, summarised here

I recommend you start with the Lua and Codea ebooks.

Ok thanks @Ignatz and @dave1707

Thanks for helping me!
And here is the itranslater beta
Its not the best but i work

If you write something the words will be displayer on the screen
I dont want that i want the answer to be displayed instead


-- itranslate beta
function setup()
    print("please dont write with big words like A. everything you translate will be translated to swedish")
    parameter.text("translate")
    parameter.action("answer",answer)
end

function answer()
    if translate=="hello" then
        print("hej. on swedish")
        translate=""
        
    elseif translate=="goodbye" then
        print("hejdå. on swedish")
    else
        
        
    if translate=="thanks" then
            print("tack!. on swedish")
            translate""
        elseif translate=="what are you doing?" then
                print("vad gör du?. on swedish")
            else
                print("i dont know what you want to translate")
        end
    end
end

function draw()
background(73, 168, 53, 255)
    
      fill(255, 255, 255, 255)
    fontSize(60)
    font("AmericanTypewriter")
    textWrapWidth(WIDTH)        -- i want the output/translated on the screen instead of that im writting
  
    sprite("Documents:CodeaCommunityClientBtn",WIDTH/2, HEIGHT/2)
    text(translate, WIDTH/2, HEIGHT - 160)
    
   
    end

@Gamerage13 I took the code I posted for someone else on the forum and modified it a little to do what you were doing. Try this and if you like it, make whatever changes you want.


displayMode(FULLSCREEN)

function setup()
    createTable()
    rectMode(CORNER)
    textMode(CORNER)
    showKeyboard()
    str="Enter a word or phrase, then press return."
    textWrapWidth(480)
end

function draw()
    background(80,80,80)

    fill(0)
    noStroke()
    rect(220,HEIGHT/2+110,500,100)

    fill(255)
    stroke(255,0,0)
    strokeWidth(5)
    rect(200,HEIGHT/2+130,500,100)
    
    if keyboardBuffer()~=nil and keyboardBuffer()~="" then
        str=keyboardBuffer()
    end
    
    fill(255,0,0)
    text(str,210,HEIGHT/2+140)
    
    if rtn then
        rtn=false
        translate()
        hideKeyboard()
        showKeyboard()
    end
end

function translate()
    for z=1,#tab1 do
        if str==tab1[z] then
            str=tab2[z]
            return
        end
    end
    str="I dont know what you want to translate."    
end

function keyboard(k)
    if k==RETURN then
        rtn=true
    end 
end

function touched(t)
    if t.state == ENDED then
        showKeyboard()
    end
end

function createTable()
    tab1={
        "hello",
        "goodbye",
        "thanks",
        "what are you doing?"}
    
    tab2={
        "hej. on swedish",
        "hejdå. on swedish",
        "tack!. on swedish",
        "vad gör du?. on swedish"}
end

@dave1707
Nice work I really like that you did! 5 - 5 stars :slight_smile:

Side note: You don’t have to tell users they can’t use uppercase letters, you can just use string.lower.

31

Ok

32

@Gamerage13 - here is another way to do it

Put the words in a dictionary format so you can look them up

Here is a table of words

function createTable()
    tab1={
        ["hello"]="hej",
        ["goodbye"]="hejdå",
        ["thanks"]="tack!",
        ["what are you doing?"]="vad gör du?"
        }
end

and now it’s much quicker to look them up (when you have thousands of words, later on)

function translate()
    --this line looks up the word in the table
    --if it doesn't find it, str wil be nil, and the "or" part makes str = the error message
    local str2=tab1[str] or "I don't know what you want to translate." 
    --put the result on two ines, English first, \
 goes to the next line
    str="English: " .. str .. "\
" .. "Swedish: " ..str2 
end

This isn’t necessarily better than Dave1707’s solution. Although it’s faster to look up, it can’t translate the other way from Swedish to English, whereas Dave has two tables and can look up either one, so it can translate both ways.

Ok thanks @ignatz :slight_smile:
