How do I make a "if key press space or up or w key" kind of statement?

[Starpat]

Code: Select all

on keyDown theKey
   if theKey is space then
      put -1 into birdDirection
   end if
end keyDown

Hello! I have a question. What if in the code I want to put a "if key space or key up or key w" how do I do that? Sorry If I'm a newbie but please help me please. I'm making a flappy bird game following a udemy course on livecode by the way.

Hello Starpat

Instead of typing out "space", try hitting the spacebar instead and wrapping it in quotes. For instance (tested)

Code: Select all

on keyDown theKey
   if theKey is "q" then move button 1 relative 0,+5
   if theKey is " " then move button 1 relative 0,-5
end keyDown

If you read the keyDown entry in the dictionary, the relevant part is -

Parameters:
The keyName is the actual character of the pressed key.

Well here's the code in the cardScript that I used to trap for SPACE and 'w':

Code: Select all

on keyDown KD
   put empty into fld "fRESULT"
   if KD is " " then
      put "Space" into fld "fRESULT"
   else
      if KD is "w" then
         put "w" into fld "fRESULT"
      end if
   end if
end keyDown

I don't think you can trap in the same way for 'key up' as you suggest;

"if key space or key up or key w"

[richmond62]

If by 'key up' you mean
the arrowKey up then that's altogether different:

Code: Select all

on arrowKey AK
if AK is "up" then
--do something
end if
end arrowKey

[Starpat]

Okay I'll try it.

[richmond62]

Arrow keys are dealt with arrowKey,

other keys with keyDown

if you want to work with both arrowkeys and others in the same script then you'll
have to use rawKeyDown and find out their rawKey codes.

Code: Select all

local birdDirection
local birdVerticalSpeed
local gameIsRunning
local citySpeed
on preOpenCard
   put 1 into birdDirection
   put 4 into birdVerticalSpeed
   put 3 into citySpeed
end preOpenCard
on startGame
   preOpenCard
   put true into gameIsRunning
   flapBird
end startGame
on stopGame
   put false into gameIsRunning
   set the bottom of button "Bird" to 400
end stopGame
// move bird up and down
on flapBird
   // move bird
   put the bottom of button "Bird" into newPosition
   add(birdDirection * birdVerticalSpeed) to newPosition
   set the bottom of button "Bird" to newPosition
   // move City_Background1
   put the right of button "City_Background1" - citySpeed into newLoc
   if newLoc < 0 then
      set the left of button "City_Background1" to the right of button "City_Background2" - citySpeed
   else
      set the right of button "City_Background1" to newLoc
   end if
   // move City_Background2
   put the right of button "City_Background2" - citySpeed into newLoc
   if newLoc < 0 then
      set the left of button "City_Background2" to the right of button "City_Background1"
   else
      set the right of button "City_Background2" to newLoc
   end if
   
   //
   if gameIsRunning then
      send flapBird to me in 0.02 seconds
   end if
end flapBird
// control bird movements
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 keyUp
   put 1 into birdDirection
end keyUp

So I've tried and it kinda works but not quite still. My flappy bird in the game is meant to go up once with the keep press but when I use the up arrow key it continues to go up after I pressed it.

how do i put in image please too (edit: thanks for telling me )

I'll come back to you after supper.

Sorry, I got distracted last night.

Code: Select all

on rawKeyDown RAWK
   put empty into fld "fKEE"
   switch RAWK
      case "32"
         put "SPACE" into fld "fKEE"
         break
      case "119"
         put "w" into fld "fKEE"
         break
      case "65362"
         put "UP" into fld "fKEE"
         break
      default
         pass rawKeyDown
   end switch
end rawKeyDown

on startGame

seems odd as "startGame" is not standard LiveCode.

I cannot see where "startGame" is called inwith that script.

[bogs]

I would have to guess it is called from elsewhere, like a button script where the button is named 'Start'

how do i put in image please too

I'm so attached...

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

Yes, but only after you have at least 10 postings!
So in your next (but one) posting you can add images, links etc.

Map looks good, but tough to figure out how to play it without reading the code
