/** @file

* All disaster/easter egg vehicles are handled here.
|
||||
* The general flow of control for the disaster vehicles is as follows:
|
||||
* <ol>
|
||||
* <li>Initialize the disaster in a disaster specific way (eg start position,
|
||||
* possible target, etc.) Disaster_XXX_Init() function
|
||||
* <li>Add a subtype to a disaster, which is an index into the function array
|
||||
* that handles the vehicle's ticks.
|
||||
* <li>Run the disaster vehicles each tick until their target has been reached,
|
||||
* this happens in the DisasterTick_XXX() functions. In here, a vehicle's
|
||||
* state is kept by v->current_order.dest variable. Each achieved sub-target
|
||||
* will increase this value, and the last one will remove the disaster itself
|
||||
* </ol>
|
||||
* @see ChunkHandler
|
