Module testing for properties of creatures, whether they are reloading, etc.
|
|
Each function takes the world and a creature and returns a bool.
|
|
Note that the creature NEED NOT be the same as the creature with that id in the world,
|
|
in fact in some cases a creature with that id may not even exist.
