gunscript: Yeah i know how unoriginal

[Liberated]

Okay so im working on a gunscript.

PHP Code:

//#CLIENTSIDE

function onWeaponFired()
{
  shoot(player.x + 1.5 + vecx(player.dir), player.y + 2 + vecy(player.dir), player.z, (playerdir + 1) * pi / 2, NULL, NULL, "era_bulletfx", NULL);
  setani("firegani", NULL);
  freezeplayer(0.5);
  
}
function onActionProjectile()
{
   player.hearts -= 2;
} 


I don't know what im doing wrong, i don't really understand the shoot command yet, but it's not showing the bullet flying.
Oh and, sometimes if i shoot while walking and shoot again i hurt myself :s
as for this one.

PHP Code:

//#CLIENTSIDE
function onKeyPressed()
{
  temp.equip = 1;
  if (keydown(5))
  {
    if(temp.equip == 1)
    {
      temp.equip = 0;
      setani("gunequip", NULL);
      sleep(1);
      setani("gunidle", NULL);
    } 
    else
    {
      temp.equip = 1;
      setani("idle", NULL);
    }
  }
}
function onWeaponFired()
{
  if(temp.equip == 0)
  {
    shoot(player.x + 1.5 + vecx(player.dir), player.y + 2 + vecy(player.dir), player.z, (playerdir + 1) * pi / 2, NULL, NULL, "era_bulletfx", NULL);
    setani("gunidlegani", NULL);
    freezeplayer(0.1);
  }
}
function onActionProjectile()
{
   player.hearts -= 2;
} 


I need to figure out if the player is moving or standing still, to add a walking/idle gani to it, but i have no idea how to check it, also, the ganis don't seem to be working on this one, i haven't made any gani's myself yet, so i used those of a server, and i even uploaded them to testbed, but they still don't work.

i would've checked the wiki for the shoot command, but as we all know that's temporarily down.

I myself think i need a timeout function that will constantly check if the player is moving or standing still
