Spawning and interacting with game elements

• spawn NPCs
  • NPC movement
  • set destination(s)
  • automatic cycling of detinations once reached
  • trail of last positions
• collision of "protagonist" with NPCs
  • camera shake effect to emphesis event
  • adjustment to length of "protagonists" trail after collision

TODO -- fuck yeah

• spawn 10 npc
• set npc movement to go back and forth between 2 destinations
  • allow movement
  • setable destination
  • setable secondary destination
  • toggle 1st, 2nd destinations
  • debug destinations as objects tend to get stuck at the start or at a destination
• allow npc to cycle through a list of destinations
• add trail of previous locations
• consider collisions
  • despawn an object
  • add screen shake on impact with protagonist
• visual effects class
  • consider the possibility of subclassing entity to make a effemeral object for visual effects
• collision refinement
  • don't consider collision if the colliding objects are not on the same parallax value.
• allow bullet time for a "hero" entity
• allow bullet time to affect a list of entities
• allow scallable magnitude for the bullet effect

TODO -- mehh, when I feel like it. maybe

• refactor code # its getting messy
