..im just wondering, is there a way to perform sort of FlushKeys() command but only for specific character ?

Function flushOneKey(keycode%)
	KeyHit(keycode)
	EmitEvent (CreateEvent(EVENT_KEYUP,, keycode))
End Function

Just calling the Key_hit function for the specific key was enough for me...

This caused the key to be buffered and the jump executed at the next available opportunity (pseudo code)..

if ( not OnGround )
  continuejump()
else 
  if ( keyhit( key_space ) )
     jump()
  end if 
end if

Whereas, checking the key every update was what I needed to to..

local wantJump:Int = keyhit( key_space )
if ( not OnGround )
  continuejump()
else 
  if ( wantJump )
     jump()
  end if 
end if

I would say:

Function FlushOneKey(keycode:Int)
	While KeyHit(keycode);Wend
End Function

While KeyHit(keycode);Wend

KeyHit returns count of hitings from last call of KeyHit/FlushKey, and set counter to 0.
So a While/Wend is not neccesary.
