Initialization

init_ai_objects

For each ship objects, call init_ai_object.

init_ai_object(int objnum)

Initialize ai_info structure of object `objnum'.

ai_object_init(object *obj, int ai_index)

FIXME

Update

ai_process

This method is called once a frame by ship/ship.cpp in ship_process_post.

1. init_ship_info
2. create_waypoints
3. ai_frame
4. if not in docking or warping modes: do read flying controls (?)

ai_frame

1. possibly: ai_warp_out
2. ai_maybe_self_destruct
3. ai_process_mission_orders
4. possibly: ai_avoid_shockwave, ai_abort_rearm_request
5. ai_do_repair_frame
6. possibly: ai_await_repair_frame
7. maybe_big_ship_collide_recover_frame
8. ai_preprocess_ignore_objnum
9. ai_manage_shield
10. ai_maybe_depart
99. ai_execute_behavior

ai_execute_behavior

Branch on different ai submethods, given the ai_info->mode received as argument:

AIM_CHASE: call ai_chase or evade_weapon or [...]
AIM_EVADE: call ai_evade or [...]
AIM_STILL: call ai_still
AIM_STAY_NEAR: call ai_stay_near
AIM_GUARD: call ai_guard
AIM_WAYPOINTS: call ai_waypoints
AIM_FLY_TO_SHIP: call ai_fly_to_ship
AIM_DOCK: call ai_dock
AIM_NONE: do nothing
AIM_BIGSHIP: call ai_big_ship
AIM_PATH: call ai_find_path then ai_path
AIM_SAFETY: call ai_safety
AIM_EVADE_WEAPON: call evade_weapon
AIM_STRAFE: call ai_big_strafe or set to AIM_NONE
AIM_BAY_EMERGE: call ai_bay_emerge
AIM_BAY_DEPART: call ai_bay_depart()
AIM_SENTRYGUN: call ai_sentrygun()
AIM_WARP_OUT: do nothing: this case is handled directly from ai_frame
AIM_GET_BEHIND: see FIXME
default: should not be there, just abort

Eventually call mabe_evade_dumbfire_weapon, when FIXME.

Behaviors

Docking

Mode: AIM_DOCK

Enterring AIM_DOCK:

ai_dock_with_object: ask for a `docker' object to dock with a `dockee' one, possibly enter one fo the following submodes:
- AIS_DOCK_0: start docking
- AIS_DOCK_4A: dock instantly
- AIS_UNDOCK_0: start undocking

Handler: ai_dock

Approach a ship, follow path to docking platform, approach platform; after awhile, undock.

Docking is decomposed in several steps:

AIS_DOCK_0: find a path to the dockee then enable submode AIS_DOCK_1.
AIS_DOCK_1: follow the path previously built until just before the last point. Switch to AIS_DOCK_2 when the point preceding the last one is reached.
AIS_DOCK_2: do final approach: orient docker correctly then approach dockee. Once close enough, swith to submode AIS_DOCK_3.
AIS_DOCK_3: eventually dock. Call `ai_do_objects_docked_stuff' to decide wether to switch to AIS_DOCK_4 (rearm/repair) or to AIS_DOCK_4A (just wait).
AIS_DOCK_4A: just sit where docker is, waiting for further orders. When goal is AI_GOAL_DOCK, this means mission goal completion.
AIS_DOCK_4: rearm/repair by calling `ai_do_objects_repairing_stuff'. If the dockee is going too fast, abort by calling `ai_abort_rearm_request'.

Undocking is decomposed in several steps:

Chasing

Mode: AIM_CHASE

Enterring AIM_CHASE:

ai_attack_object: enter SM_ATTACK submode

Handler: ai_chase
