Adventure Game Studio

I'm trying to call a function for bullet trajectory, but I can't call the function, and the manual isn't very specific about function syntax. As it is, it says the function shot_vector is an undefined token.

the function call is in the mouse click function, and shot_vector, the function I'm trying to call is at the bottom of the code.

here's the code, all of this is in global.asc.    Thanks

// main global script file

// called when the game starts, before the first room is loaded
function game_start()
{
KeyboardMovement.SetMode(eKeyboardMovement_Pressing);

}

// put anything you want to happen every game cycle in here
function repeatedly_execute()
{
 
}

// called when a key is pressed. keycode holds the key's ASCII code
function on_key_press(eKeyCode keycode)
{
  if (IsGamePaused()) keycode = 0; // game paused, so don't react to keypresses
 
  if (keycode == eKeyCtrlQ) QuitGame(1); // Ctrl-Q
  if (keycode == eKeyF9) RestartGame(); // F9
  if (keycode == eKeyF12) SaveScreenShot("scrnshot.pcx");  // F12
  if (keycode == eKeyCtrlS) Debug(0,0); // Ctrl-S, give all inventory
  if (keycode == eKeyCtrlV) Debug(1,0); // Ctrl-V, version
  if (keycode == eKeyCtrlA) Debug(2,0); // Ctrl-A, show walkable areas
  if (keycode == eKeyCtrlX) Debug(3,0); // Ctrl-X, teleport to room
 
  /*  //brandon's stuff, now useless
  if (IsKeyPressed(eKeyUpArrow) == 1)
  cglitch.Walk(cglitch.x, cglitch.y-10);
  if (IsKeyPressed(eKeyDownArrow) == 1)
  cglitch.Walk(cglitch.x, cglitch.y+10);
  if (IsKeyPressed(eKeyRightArrow) == 1)
  cglitch.Walk(cglitch.x+10, cglitch.y);
  if (IsKeyPressed(eKeyLeftArrow) == 1)
  cglitch.Walk(cglitch.x-10, cglitch.y);
  //end brandon
*/

  if (IsKeyPressed(eKeyQ) == 1)
  {
   /* DrawingSurface *surface = Room.GetDrawingSurfaceForBackground();
surface.DrawImage(cglitch.x,  cglitch.y-60, 11);
surface.Release();*/
   
   
  /*  DrawingSurface *surface = Room.GetDrawingSurfaceForBackground();
surface.DrawingColor = 14;
surface.DrawLine(cglitch.x, cglitch.y, mouse.x+16, mouse.y+16);
surface.Clear();
surface.Release();
*/

function shot_vector(int cglitch.x, int cglitch.y, int mouse.x,  int mouse.y)
{

  criflebullet.ChangeRoom(1, 0, 0);
  criflebullet.Move(cglitch.x,  cglitch.y);
  int vectorx;
  int vectory;
  vectorx = mouse.x - cglitch.x;
  vectory = mouse.y - cglitch.y;
  while((-30<criflebullet.x<830) && (-30<criflebullet.y<630))
  {
  criflebullet.Move(criflebullet.x+vectorx, criflebullet.y+vectory);

  return;
}

Move the function shot_vector() on top of on_mouse_click(). You cannot call a function that is declared after the current one.

Thanks
