|
// 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.
