problem with static struct

Murasame

Okay, this is in correlation to a problem I had earlier. I am attempting to create a version of geyKeyboardState that runs on events, so instead of updating it constantly, it only updates when a new event occurs. for those of you who don't understand why I do it this way, you have to call al_get_keyboard_state(foo) every time the keyboard state needs to update. it does not do so automatically, and any reallocation is not done until you tell it to. and since I use events for everything else, why not use it for this too?

My Current solution uses a struct:

#SelectExpand
  1//KeyHeld header file
  2#ifndef KEYHELD_H
  3#define KEYHELD_H
  4#include "allegro5/allegro.h"
  5struct keyHeld
  6{
  7  static bool isKeyHeld [ALLEGRO_KEY_MAX];
  8  static void refocus(ALLEGRO_KEYBOARD_STATE *);//should be called whenever the game regains focus
  9  static void keyDown(int);
 10  static void keyUp(int);
 11};
 12#endif

and

#SelectExpand
  1#include "keyHeld.h"
  2
  3void keyHeld::refocus(ALLEGRO_KEYBOARD_STATE * keys)
  4{
  5  for (unsigned int x = 0; x<ALLEGRO_KEY_MAX; x++)
  6  {
  7    if (al_key_down(keys,x))
  8    {
  9      isKeyHeld[x] = true;
 10    }
 11    else
 12    {
 13      isKeyHeld[x] = false;
 14    }
 15  }
 16}
 17void keyHeld::keyDown(int keycode)
 18{
 19  isKeyHeld[keycode] = true;
 20}
 21void keyHeld::keyUp(int keycode)
 22{
 23  isKeyHeld[keycode] = false;
 24}

and is called in main like so:

#SelectExpand
  1#include "keyHeld.h"
  2//one of many includes. not all are listed here to save your eyeballs
  3int main(int argc, char **argv)
  4{
  5ALLEGRO_EVENT_QUEUE *event_queue = NULL;
  6  event_queue = al_create_event_queue();
  7  if(!event_queue) {
  8    fprintf(stderr, "failed to create event_queue!\n");
  9    al_destroy_display(display);
 10    al_destroy_timer(timer);
 11    return -1;
 12  }
 13//skips some data here too
 14  al_register_event_source(event_queue, al_get_display_event_source(display));//registers display events
 15
 16  al_register_event_source(event_queue, al_get_timer_event_source(timer));//registers timer events
 17
 18  al_register_event_source(event_queue, al_get_keyboard_event_source());//registers events for keypress
 19
 20  ALLEGRO_EVENT ev;//for event listener
 21//... skips a lot of code here that does not affect anything dealing with this.
 22  else if (ev.type == ALLEGRO_EVENT_KEY_DOWN) //if a key is pressed
 23    { 
 24      cout << "registers a keypress";
 25      keyHeld.keyDown(ev.keyboard.keycode);
 26    }

my problem is that I get compile errors wherever I put the word keyHeld in main. the error is always expected a ";" before ".". I had a buddy look at it, and he didn't know what the problem was either. perhaps we are both a bit sleep deprived, and overlooked something stupid. regardless, any help would be appreciated

l j

keyHeld::keyDown(ev.keyboard.keycode);?

I now feel stupid. I guess fatigue really can screw you up. thanks for the really simple fix. I cannot believe we missed that
