Yeah yeah the first if statements dealing with newdirection waste space and are unnecessary. I'll fix eventually but it works just fine and doesn't need to be fixed NOW.

So my issue... The commented out portion, just below those first if statements, is an attempt to detect when character and boss cross paths. Either x coordinates or y coordinates match up.

This is not working. He sometimes shoots in the wrong direction or just doesn't shoot.

I was wondering if anyone could help me devise a simple way in which I could test for cross passing. And if they cross paths, then have him shoot int he proper direction.

Btw: newdirection = 4 - shoot right, 5 - shoot left, 6 - shoot up, 7 - shoot down.
0 - boss moves right, 1 - moves left, 2 - moves up, 3 - moves down.

Do you mean something like:

if ( boss.x == player.x && boss.y == player.y )
{
  // Spot on, bite, stomp, ...
}
else if ( boss.x == player.x )
{
  if ( boss.y < player.y ) // Shoot up
  else // Shoot down
}
else if ( boss.y == player.y )
{
  if ( boss.x < player.x ) // Shoot right
  else // Shoot left
}
