User input into a variable

General
1

I need clarification on how to make user input from the keyboard into a variable. My father put me up to creating a code that calculates QB ratings for quarterbacks in the NFL. So I need to figure out how to shove input from the user (from a keyboard) into a variable. I already have the keyboard working. Thanks!

Easy way is use a parameter. Or just save the keyboard buffer after enter is pressed into a variable. You may want to look at Cider 7 for creating a UI if you chose not to use parameters.

function setup()
--MyVar will store user input.
   parameter.text("MyVar","QB name") 
end
function draw()
    background(0, 0, 0, 255)
text(MyVar,WIDTH/2,HEIGHT/2)
end

@JessicGriffin The response I gave you in your other post ( Need Help: Keyboard Input ) shows how to get keyboard input into a variable. See the keyboard(k) routine.

@JessicGriffin Yes. You would “ask the question” and save the input into different variables. Then use those variables for what you want.

@JessicGriffin Here’s a quick example of inputting data using the screen instead of the output area. It’s set up for 2 questions and just outputs those input values. There will be a lot of changes for what you want, but the majority of what you need is here.


displayMode(FULLSCREEN)

function setup()
    inp=1    
    var1=""
    var2=""
    str = ""
    bcolor= 0
    x=300
    y=500
    w=200
    h=50
    l=x-w/2    --button left
    r=x+w/2    --right
    b=y-h/2    --bottom
    t=y+h/2    --top
end

function draw()
    background(30,30,0,255)
    strokeWidth(6)
    rectMode(CENTER) 
    textMode(CENTER)        
    fill(255)
    text("Tap button then input data.",x,450)
    text("Press RETURN to show input.",x,400)    
    if bcolor == 0 then
        fill(255, 0, 0, 255)
    else
        fill(128,0,0,255)
    end    
    rect(x,y,w,h)    -- input area        
    fill(255)
    if keyboardBuffer() ~= nil then
        text(keyboardBuffer(),x,500)    -- show data as it is keyed
    else
        text(str,x,500)    -- show data in input area  
    end  
    if inp==1 then
        text("Enter number of passes attempted.",300,700)
    elseif inp==2 then
        text("Enter number of passes completed.",300,700)
    end
    if inp==1 and str~="" then
        var1=str
        str=""
        inp=2
    end
    if inp==2 and str~="" then
        var2=str
        str=""
        inp=1
    end
    rect(x,HEIGHT-100,150,50)
    rect(x,HEIGHT-200,150,50)
    fill(255,0,0)
    text(var1,x,HEIGHT-100)
    text(var2,x,HEIGHT-200)
end

function touched() -- check if input area was touched
    if CurrentTouch.x > l and CurrentTouch.x < r then
        if CurrentTouch.y > b and CurrentTouch.y < t then
            showKeyboard()
            bcolor = 1
        end
    end
end

function keyboard(key) -- move keyboardBuffer to str when return is pressed
    if key == RETURN then
        str = keyboardBuffer()
        hideKeyboard()
        bcolor = 0
    end
end

So would it be able to store information from each thing the user inputs? I need to make inputs to see how many passes completed, attempted, yards gained, touchdowns, and interceptions. There will be a button to switch to the next thing (At the beginning it will ask for how many passes attempted, then the user would hit a button and it would ask for the next thing…etc)

I never use the keyboardBuffer() function, just something like string = string … key in function keyboard(key).

@SkyTheCoder Using the keyboardBuffer() allows the use of the backspace key and other things without having to code for it. I don’t like the fact that the buffer can’t be cleared unless you do a hideKeyboard, showKeyboard.

Thanks everyone for the information. I’m hoping I can figure this out :slight_smile:
