Notifications - called from javascript. You request orders with a target entity, order type, and whether the previous listeners you have requested for this entity should be destroyed. When the target entity processes an order that was requested, that order is pushed onto the queue of the requester. This is useful for things such as follow that require the actual order to perform the action. This was SVN commit r3329.

|
// Entity orders structure.
|
|
//
|
|
// Usage: All orders at this point use the location component of the union.
|
|
// Orders are: ORDER_GOTO_NOPATHING: Attempts to reach the given destination via a line-of-sight
|
|
// ORDER_GOTO_SMOOTED: system. Do not create an order of these types directly; it is
|
|
// used to return a path of line segments from the pathfinder.
|
|
// _SMOOTHED flags to the entity state-control that it's OK to
|
|
// smooth the corner between segments. _NOPATHING just does
|
|
// zero-radius turns.
|
|
// ORDER_GOTO_COLLISION: When the coldet system is trying to get us out of a collision,
|
|
// it generates these intermediate waypoints. We don't really have
|
|
// any reason to go to this specific point, so if a better way
|
|
// comes along, this order can be deleted.
|
|
// ORDER_GOTO: Attempts to reach the given destination. Uses the pathfinder
|
|
// to... er... find the path.
|
|
// Create this order when a standard movement or movement waypoint
|
|
// order is required.
|
|
// ORDER_PATROL: As ORDER_GOTO, but pushes the patrol order onto the back of the
|
|
// order queue after it's executed. In this way, the entity will
|
|
// circle round a list of patrol points.
|
|
// Create this order when a standard patrol order is required.
|
|
// ORDER_ATTACK_MELEE: Move towards target entity; start bashing it when close enough.
|
|
// If we collide with something (=> line-of-sight tracking no longer
|
|
// sufficient) spawns a ORDER_GOTO to target's location and pushes it
|
|
// immediately in front of this order.
|
|
//
|
|
// Entities which exhaust all orders from their queue go to idle status; there is no specific order
|
|
// type for this status.
