Last change on this file since 12201 was 11708, checked in by landauf, 7 years ago

[HUD_HS16] fixed issue that the hud shows pickups of ALL players/bots instead of just the own spaceship. fixed this by comparing objectIDs
note: network calls currently support only 5 arguments, so I removed representationObjectId which doesn't seem to be used (neither in C++ nor in Lua)

40    @brief
41        ActionpointController is a state machine with states:
42            1) NONE
43            2) FLY: fly towards a point
44            3) FIGHT: fight enemies that are in attackRange_ (see FightingController)
45            4) PROTECT: follow this->protect_
46            5) FIGHTALL: fight all enemies on the map
47            6) ATTACK: fight a specific spaceship
48        This controller always executes an action that is in the back of the vector being used.
49        After current this->action_ is completed, next action becomes the top action (one that will
50        be returned by someVector.back()), and current action either will be removed (if not looping),
51        or moved to the top (if looping).
52
53        Every second action(), which is once in two seconds, this searches the area for enemies that are in attack range, if finds anyone,
54        pushes Action::FIGHT to the stack. That makes spaceship fight enemies inside of a sphere, and when all enemies in range are dead,
55        Action::FIGHT is removed from the stack, and spaceship resumes doing whatever action was being executed before.
56
57        In XML one has to attack Actionpoints in order to achieve any complex behaviour, but in Controller all actionpoints are effectively
58        being stored in an array of type Point::Value.
59    @note
60        ActionpointController will not work, if there is no MasterController in the level!
61        All the demos are in a file called AITest.oxw. In the menu look for New AI Testing Level.

112                Full description:
113                Adds an Actionpoint to this->actionpoints_. Actionpoint can take arguments like action="attack" attack="name".
114                For documentation on Actionpoint XML arguments, check out Actionpoint.h class
115                If any WorldEntity that is not Actionpoint or its child being sent to actionpoints through XML,
116                action would be assumed to be Action::FLY and target position to be position of the entity. Also, if not Actionpoint
117                is passed, it is assumed to be in a loop. How it works is: in \<actionpoints\> first all Actionpoints between
118                first Actionpoint with loopStart=true and first following Actionpoint with loopEnd=true are included in a single loop.
119                If they are adjacent (in the input array) with WorldEntity, then WorldEntity is also in a loop.
120                All the Worldentities are assumed to be in loop.
121               
122                Loop example:
