Using keystokes rather than mouse

Question

Hey folks,
I'm a bit of a novice at this lingo so if anyone can help
out there it'd be much appreciated. I'm creating a sliding tile
puzzle game, and the lingo that is operational allows the tiles to
move on mouse clicks. However I want to alter the code so that the
individual tiles (Sprites 1-9) move on their relevant keys i.e.
1-9. I'm using sendAllSprites to move the tiles on the mouse but
I'm stuck with the keystroke command. I guess I'm supposed to put
individual code on each of the sprites with the relevant
'keystroke' command????

Hi,
There are a few different ways you can do it:
1. Check for #keyDown events
2. Check, on every #exitframe, what keys are currently
pressed using KeyPressed()
3. Use the 'keyDownScript'
To respond to Keydown events, you need to remember that
#keyDown events are only sent to certain sprite types (editable
text etc). If your tiles are bitmaps, they probably wont receive
#keyDown. In this case, using a frame script like this might help
on keyDown (me)
k = the key
case(k) of
"1": doSomething()
etc
end case
end
With the second approach, you would add a behaviour like this
onto each of the individual tile sprites:
on exitframe (me)
if keyPressed(thekeythatIamInterestedIn) then
doStuff()
end if
end
With the third approach, you would do something like this
on startMovie
the keyDownScript = "MyKeyControlScript"
end
on MyKeyControlScript ()
k = the key
case(k) of
"1": doSomething()
etc
end case
end
