"and" not working for two keys down

[CreativeOcclusion]

It seems that the "and" statement is not working for 2 keys down at the same time...Unless I have the syntax wrong or something...Thanks for any help....Here is a code sample that is not working...This is in a function onKeyDown(key)...

Code: Select all

   if (key == "shift" and key == "w") then
      sound.play2DSound( runsound_ID );
      anim.setSpeed(obj, "Walk", 2.8);
   end

onKeyDown(key) sends an event immediatelly when a key is pressed. This means "shift" and "w" are triggered seperately. Even if not your code requires "shift" == "w", which will obviously always return false.
Solution:

Code: Select all

if (key == "w" and input.keyDown("shift")==1)) then

if you want multiple keys with shift and only mondify e.g. speed by the shift-key this saves you some lines of code and code doubling (haven't gone into movement, so the example is repositioning)

Code: Select all

if (string.find("ijkluo",key) > 0 and not key == "") then
   sky.lprint("DEBUG: moveObj");
   sky.lprint("DEBUG: shift: "..input.keyDown("shift"));
   if (input.keyDown("shift") == 1) then
      d = d/20;
   end
   if (key == "i") then
      x,y,z = entity.getPosition(eid); -- eid=0 -> crash
      y = y+d;
      entity.setPosition(eid,x,y,z);
   elseif (key == "j") then
.....
   end
end


Unfortunately, all this will not work with numbers.

Code: Select all

if (key == "0") then
   if (input.keyDown("shift")==1) then
      sky.lprint("THIS IS UNREACHABLE");
   end
end


The reason can be seen with Debug-Messages:

Code: Select all

sky.lprint("DEBUG: keyPressed("..key..")");

shift+0 will NOT trigger key="0", but key="".

Unfortunately the following won't work, too. input.keyDown("0") does work, but only if pressed without a modifier key. First "0" then Shift has keyDown("0")==1, but obviously that triggers a 'plain' "0" first, which is unusable for hotkeys.

Code: Select all

if (key == "" and input.keyDown("shift")==1 and input.keyDown("0")==1) then

Hope this helps with your problem(s).

As PaRaDoXos has mentioned, only 1 key is sent through at once. To get around this, when the shift key is pressed or released, store a variable for isShiftPressed.

e.g.

Code: Select all

isShiftPressed = false;
function onKeyDown( key )
     if(key == "shift")then isShiftPressed = true; end

     if(key == "w" and isShiftPressed) then
          -- set the run speed
     end
end

function onKeyUp( key )
     if(key == "shift")then isShiftPressed = false; end
end


well, thats how i would approach this, the only problem is that the w key will not be retriggered if it is held down and the shift key is released or pressed. Which is why movement we tend to handle in the update loop to adapt the speeds on the keys pressed.

All methods are valid i think

i will just end up moving this to the onUpdate()....The main problem I'm having is that These adjustments are being made to the FPS Kit Player...The micro-script for this player contains none of the movement code or keys code...The shift and w key work fine together for the FPS Player...

I am just adding footsteps sounds for run and walk, and changing the animation speed for the walk animation...The actual movement is controlled from somewhere unseen...If this code was visible to me I could easily manipulate it to do what I want, without having to guess at it....I can find no code attached to the character controller...I may end up just having to code my own character controller....Thanks for the help, @PaRaDoXoS and @SolarPortal...

i would wait until the new FPS player before writing a new one
