.enemy

.movetarget
The next path spot to walk toward. If .enemy, ignore .movetarget.
When an enemy is killed, the monster will try to return to it's path.

Set to time + something when the player is in sight, but movement straight for
him is blocked. This causes the monster to use wall following code for
movement direction instead of sighting on the player.

A yaw angle of the intended direction, which will be turned towards at up

this will be the exact line towards the enemy.
.pausetime
A monster will leave it's stand state and head towards it's .movetarget when
