stop when street is blocked

[Fusselwurm]

driving AI is not to be trusted.
the least we can do is check for people / cars* blocking the street, and fucking wait instead of going around or over obstacles.

*as long they're in working condition

might be implemented using customActivity:

start:

• save remaining waypoints
• remove waypoints

stop:

• restore waypoints

... still, unit would first rally again, re-creating any waypoints. soooo... we'd need to look for existing waypoints in all waypoint-creating routines.

ugh also - we'd do this using a new state, and calling customActivity from a state is yuck.

so: new car business state "traffic_jam" with transition from and to bus_voyage | bus_transit

edit2:

// stop:
doStop driver vehicle leader _this;

// resume:
_group group _this;
units _group doFollow leader _group

that's NEAT that is!

problem: vehicle would stop as soon as blockage is detected, which might be quite some way off (depending on speed).

example: vec going at 30m/s with 2s scan interval would need to scan (60m+<brake distance>) ahead, might end up stopping directly behind target or up to 60m away which is a bit too far. I want to bumpers to contact. It's supposed to be a traffic jam ffs, not a convoy excercise.

Thus, putting a waypoint might again become the best solution. Meh.

moveTo also works without removing the group's waypoints. Unofrtunately, afterwards the group currentWaypoint is invalid (index = len waypoints), so currentWaypoint index needs to be restored

btw, BIS_fnc_inAngleSector

need to differentiate between oncoming traffic and traffic flow in the same direction
