Scratch

I tried this already.  You can't drag a reporter into the hat.

Are you absolutely sure that the scripts will remain once the image is saved?

Yep! I've tried it.

Yes, you can.

Not with what I did.
Also, you really don't have to shorten my name for a quote. ^^

I'm lazy 

What if you click Quote? 

Try editing Scratch-Blocks -> KeyEventHatMorph -> --all-- initialize.

This would do so much better in the Suggestions section of the forums.    But I'm sure they'll add a lot of things ( hopefully ) in Scratch 2.0 and I hope this is in it.

Sparks: Add this to Panther, or at least add it to the Block Library.

The (Key pressed) block would be extremely, extremely helpful for projects like word editors. Unfortunately, it doesn't exist. Only the <key [space] pressed> boolean exists. A new block can be coded, but that means it won't work online. So, most Scratchers end up manually making a long script, with an if block for every key. That it a long job.

Solution? Well, you could get away with only one if block: here's how:

Code:

forever:
    set n to 1
    repeat 41 times:
        if <key (item (n) of [keys]) pressed>
            set [keyPressed] to (item (n) of [keys])
    change n by 1

You would need a list called keys, which had each key as an item. This would basically run through the list, testing for a key that's pressed. Great!

The catch? I cleverly assumed that you can drag reporters (round blocks like ((2) + (2))) into the <key [space] presses> block, like the [switch to costume [costume]] block. It doesn't.

Well, let's make it!

Open up the System Browser (learn how here), and navigate:
Scratch-Blocks » CommandBlockMorph » private » uncoloredArgMorphFor:

Replace all the coding with:

Code:

uncoloredArgMorphFor: t1 
    | t2 |
    t2 _ t1 at: 2.
    $a = t2 ifTrue: [^ AttributeArgMorph new choice: 'volume'].
    $b = t2 ifTrue: [^ BooleanArgMorph new].
    $c = t2 ifTrue: [^ ColorArgMorph new showPalette: true].
    $C = t2 ifTrue: [^ ColorArgMorph new showPalette: false].
    $d = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '0';
         menuSelector: #directionMenu].
    $D = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '48';
         menuSelector: #midiDrumMenu].
    $e = t2 ifTrue: [^ EventTitleMorph new].
    $f = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #mathFunctionNames;
         choice: 'sqrt'].
    $g = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #graphicEffectNames;
         choice: 'color'].
    $H = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #hookupSensorNames].
    $h = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #hookupBooleanSensorNames].
    $I = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '1';
         menuSelector: #midiInstrumentMenu].
    $i = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '1';
         menuSelector: #listIndexMenu].
    $k = t2 ifTrue: [^ ChoiceOrExpressionArgMorph new getOptionsSelector: #keyNames;
         choice: 'space'].
    $L = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #listVarMenu].
    $l = t2 ifTrue: [^ ChoiceOrExpressionArgMorph new getOptionsSelector: #costumeNames;
         choice: 'costume1'].
    $m = t2 ifTrue: [^ SpriteArgMorph new].
    $M = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #motorNames].
    $n = t2 ifTrue: [^ ExpressionArgMorph new numExpression: '10'].
    $N = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '60';
         menuSelector: #noteSelector].
    $s = t2 ifTrue: [^ ExpressionArgMorph new stringExpression: ''].
    $S = t2 ifTrue: [^ ChoiceOrExpressionArgMorph new getOptionsSelector: #soundNames;
         choice: 'pop'].
    $v = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #varNamesMenu;
         choice: ''].
    $W = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #motorDirection].
    $x = t2 ifTrue: [^ ChoiceOrExpressionArgMorph new getOptionsSelector: #sceneNames;
         choice: ''].
    $y = t2 ifTrue: [^ ExpressionArgMorphWithMenu new numExpression: '1';
         menuSelector: #listIndexForDeleteMenu].
    ^ ExpressionArgMorph new numExpression: '10'

Alt-click, and choose accept. Close the Browser. Shift-click the R again, and click 'turn fill screen on'.

Do NOT quit Scratch until I say so later!

Drag out the <key [space] pressed?> block. Take any reporter, and stuff it into the [space] dropdown list. Voila! It fits!

Now, make and run the following script (recognize it?). You will need to make 2 variables called 'n' and keyPressed. You also need to make a list called 'keys' and put every key's name in it.

Code:

forever:
    set n to 1
    repeat 41 times:
        if <key (item (n) of [keys]) pressed>
            set [keyPressed] to (item (n) of [keys])
    change n by 1

Run the script—variable keyPressed will show the key you're pressing! 

If you're holding down many keys together, it'll glitch, but that's easy to fix. Here's how:

With the same variables, make these scripts:

Code:

When key (item (n) of (keys)) pressed
set [keyPressed] to (item ((n) mod (41)) of (keys))

When green flag pressed
forever:
    change (n) by 1

Congratulations! Variable keyPressed is your (key pressed) block!

Now, you can save and quit Scratch.

Note that
1) Once you reopen Scratch, while these scripts will remain there, the key [] pressed's modification will get deleted.
2) This will work online!

Yes I have noticed this, though you made it sound like the reporter did, only a reporter which fits into it will stay there.

Next time you quote a long post, could you replace it with 'long post' or something?

what's the point?  Then we have no idea what they are referencing

YAYZ!  I will add this to my SynOS 7 patch     LESS LAG

Ok, please give me some credit.

Yeah...
It will be in somewhere....

In the comments...
Way beneath all the code...

Lol.  jk - i will find a place to put it 

I know this post is a year old, but I need to do exactly this and I would love it if this code example actually worked, but it doesn't seem to. I followed all the steps carefully, but when I got to the line "Drag out the <key [space] pressed?> block. Take any reporter, and stuff it into the [space] dropdown list. Voila! It fits!" I found that it didn't accept any reporter. I reopened the code for that block and verified that it was your version. (btw, it would have been very helpful to point out exactly what line had changed--I ended up having to paste your version and the original into different text files and use a diff tool!)

I tried all the steps several times to make sure I hadn't missed a step, but I had the same problem as scimonster--it just wouldn't accept the reporter.  Is there a step missing or a precondition that I don't have?  Thanks very much!

Well, the hat is hard to modify, but you could do this:

when gf clicked
forever
if <key (someKey) pressed?>
broadcast [somekeywaspress v]
end

when I receive [somekeywaspressed v]
say [Hi!]//Do something!

This is similar to the one in Processing right? The variable that sets to the button pressed.
