That was a half-finished thing of mine designed to make my 9-12 year old victims
suffer: they were meant to read the code! 8)

The map is ripped-off from battle for Wesnoth. :D

Once you've done the above steps, place the cursor where you want the picture to show up in the reply and click the "Place inline" button :D
Yes, but only after you have at least 10 postings!
So in your next (but one) posting you can add images, links etc.
I was still able to add images with less than 10 postings so yeah.

Code: Select all

on rawKeyDown RAWK
   put empty into fld "fKEE"
   switch RAWK
      case "32"
         put "SPACE" into fld "fKEE"
         break

         break
      default
         pass rawKeyDown
   end switch
end rawKeyDown
but this doesn't match for the code in my game.

No, it doesn't match the code in your game.

If I sorted your game out for you it would be my game. 8)

But with a bit of lateral thinking, you can use my code to help you with yours. :D

Personally I always control movement of objects on-screen with the arrowKeys ONLY.

Space, w and the UP arrowKey seem an odd combination.

I do feel that, instead of posting pictures of code and so on, you would
be far better to describe the FUNCTIONALITY you want . . .

e.g: on pressing the UP arrowKey the 'bird' moves up the screen.

Certainly my experience with both clients and students/pupils over a 28 year period is that
the best way to understand things is to sit them down in front of a large table with a handful of toys
so they can demonstrate exactly what they want in concrete terms.

LiveCode is so very flexible, and is capable of achieving the same sort of thing in so many ways
that show me your code, or my showing you my code might be like you speaking in Serbian and my speaking
in Albanian: i.e. we'd end up in Kosovo at daggers drawn: not because either of us is 'wrong' but just because
your LiveCode and my LiveCode are different.

I do not think that enough work has been done on the methodology of this sort of communication.

Hi Starpat,

the message "rawkweydown" returns a NUMBER (the keycode of the pressed key) and not its "value"!
So take another look at Richmonds script and try again.
Hint: Really no need to QUOTE numbers!

Code: Select all

...
 switch RAWK
      case 32
        ## put "SPACE" into fld "fKEE"
        ## Do your thing here when user pressed -> SPACE
         break
      case 119
         ## put "w" into fld "fKEE"
         ## Samew here for -> w
         break
      case 65362
         ## put "Arrow key UP" into fld "fKEE"
        ## and here for -> ARROW KEY UP
         break
      default
         pass rawKeyDown
...
Best

Klaus

P.S.
Your "rawkeyUP" handler will OVERWRITE ALL VALUES for birdDirection you have just set in "rawkeydown"!

I made my code like this and it finally worked! :D

Code: Select all

on keyDown theKey
   if theKey is space then
      put -1 into birdDirection
   else
      if theKey is "w" then
         put -1 into birdDirection
         end if
   end if
end keyDown
on arrowKey AK
   if AK is "up" then
      put -1 into birdDirection
   end if
end arrowKey
on rawKeyUp
   put 1 into birdDirection
end rawKeyUp

That is great to know! :D

I do think you would have found things easier using rawKeyDown
so you didn't have to invoke both keyDown and arrowKey
which might possibly interfere with each other.

Like this:

Code: Select all

on rawKeyDown tKey
 switch tKey
 
     ## SPACE, w and ARROW KEY UP do the same thing, so we can do this:
      case 32
      case 65362
      case 119
         put -1 into birdDirection
      break
    
      ## ANY other pressed keys:  
      default
          put 1 into birdDirection
      break
  end switch
end rawKeyDown
See, much cleaner and even shorter! :-)

Not that I'd like to admit this in public, but Klaus has been
something of a mentor to me for the last 20 years re LiveCode. :D
