/** The fire simulator takes care of the fire blocks.
|
|
It periodically increases their meta ("steps") until they "burn out"; it also supports the forever burning netherrack.
|
|
Each individual fire block gets stored in per-chunk data; that list is then used for fast retrieval.
|
|
The data value associated with each coord is used as the number of msec that the fire takes until
|
|
it progresses to the next step (blockmeta++). This value is updated if a neighbor is changed.
|
|
The simulator reads its parameters from the ini file given to the constructor.
