Ok ok... I got a good question.

I know leftkey(), and rightkey() But if i wanted a command for the "A" key or the "Q" key, whats the command for that?

look up "inkey" or "scancode"... check those out, there are many different ways to do it... just look a little into those

either
inkey$(a)
or
keystate(scancode) for instance the scancode for 'a' is 30
so
if keystate(30)=1 then dostuff()
clever huh?
oh and before you ask here is a very useful image for finding scancodes


how good am i?

if you have a scancode chart you could use KEYSTATE()

IF KEYSTATE(scancode value here) = 1
do whatever....
END IF

there is a scancode chart for the numeric key values in the codebase I think, or somewhere on these forums. A=30 if I remember.

`//check for A being pressed
IF KEYSTATE(30) = 1
do whatever....
END IF

hope this helps

I've posted all of the key values into the CodeBase too, so you can use 'if keystate(DIK_A) ...' instead of 'if keystate(30) ...' to keep your code a little more readable

true, but is overkill if you are using just a handful of certain keys.

i might have to start using that... would have been nice when i first starting doing this... i wrote a program that would give me the scancodes... then hit each key individually and then pencil the code on a sheet of paper

question...

how would you make it so when you hit the key it does one operation, but does not repeat, only does it once, until they let go of the key and hit it again... to make a toggle effect?

I did write a plugin a while back to convert Scancodes to ASCII, which works regardless of the country (as the keyboard layout will change in France / Germany etc.)...

I'll see if I can dig it up for you.

@Rob K
would that do a toggle effect? like hitting "W" to turn on/off wireframe mode (example)

@IanM
well the that code didnt toggle anything...
its actually for a animation... for landing gear... you hit "L" and it plays an animation of the gear going down... then hit it again to play the animation of them going up... but for some strange reason... it aint working

No, that code just ensures that when you press and hold the W key, the action only occurs once. After re-reading your question, I've come up with this:



As you'll see though, the 'do something' part of my previous code has just become the switching of a value between 0 and 1
