Small updates

Updates here are involved with the following

• adding some world objects to the radar, (though its pretty rough)., and playing with the projectiles being tracked..
• Making more complete (admittedly) lazy built worlds (just two of them) When you leave the world, and join again .. right now it just toggles back and fourth between. The end goal is to have a set. and then NPC density, and difficulty increase as you loop through them.
