The problem for an AI is to determine whether the object hit them or they hit the object. It's the same collision code in both cases. We don't want them getting alerted when they kick a box out of the way. If the velocity of the incoming object is still available after the collision, then we could differentiate between the two cases. |

But aren't thrown objects tagged with "set in motion by: player" versus "set in motion by: entity myself"? The same goes for the case where the player still has the object in the grabber - if it bumbs into an AI they should be able to tell the difference and react. |

1 – AI are now alerted, and possibly hurt, if you throw something at them. They will stop and look at the item thrown, then turn back toward where it came from. 2 – AI can be knocked out if you drop something heavier than 20kg on their head. 3 – Throwing or dropping things at/on AI will never kill them. 4 – When an AI kills an enemy, he will pause before emitting his victory bark. It was being emitted at the same time as the enemy’s death bark, making it difficult to make out either. Plus, it’s more dramatic. 5 – An AI remembers who he last killed, so that contact with the victim on his way down doesn’t cause a tactile alert to the victor. 6 – When an AI drops his weapon upon dying, that weapon won’t hurt or alert others who come in contact with it. 7 – An AI who kills an enemy won’t emit a rampdown bark. It sounded silly when they’d just killed someone, and then said something like, “I guess it was just rats” or “You win this round.” 8 – An AI is no longer alerted by the death bark of someone he just killed. 9 – Increased the tactile alert search volume from (40,40,40) to (100,100,100) because AI were just standing still and not searching. 10 – Prevent knocked-out AI from yelping with pain when something is dropped on them. rev. 5394: CombatState.cpp ObservantState.cpp State.cpp AI.cpp AI.h AI_events.cpp Memory.h Physics_RigidBody.cpp Actor.cpp Actor.h Moveable.cpp AFEntity.cpp Mind.cpp Entity.cpp MeleeWeapon.cpp rev. 12768: tdm_damage.def moveable.def tdm_movable_containers.def |

Next round: 1 – moveable weapons in the map at map start won’t hurt AI that collide with them 2 – objects dropped on the inventor with his goggles up can cause KO Rev. 5396: Actor.cpp Moveable.cpp |

Third round: 1 - Adjust velocity limits to eliminate the likelihood of damage from stepping or jumping on objects. Then I don't need to worry about what struck what. CrashLand() will take care of damage from crashing into walls or crates or whatever when riding movers or being flung from movers. 2 - If an object hits an AI when he's not searching, he should stop, look at the object for a moment, and turn to look in the direction the object came from. If he spots an enemy, he'll do his normal "Aha!" and enter combat mode. If he spots a friend, he'll go back to what he was doing. If he spots no one, and a friend/neutral threw the object, he'll go back to what he was doing. If he spots no one, and an enemy threw the object, he'll treat it as a suspicious event and start searching. If the object is heavy enough and fast enough to knock him out, it will. 3 - If an object hits an AI when he's searching, he should turn to look in the direction the object came from (assuming the search code doesn't override this somehow). If he spots an enemy, he'll enter combat mode. If he spots a friend or no one, he'll go back to what he was doing (searching). If the object is heavy enough and fast enough to knock him out, it will.

Fourth round: 1 – Put back immediate AI tactile alert when you bump them or they bump you. 2 – Allow small AI to be killed by a dropped moveable. 3 – Further corrections to KOs by dropped moveables 4 – Define new sounds for getting hit and admonishing friends when appropriate. rev 5400: Actor.cpp Actor.h AFEntity.cpp AI.cpp CombatState.cpp HitByMoveableState.cpp HitByMoveableState.h State.cpp Moveable.cpp rev 12787: tdm_ai_animal_horse2.def tdm_ai_animal_rat.def tdm_ai_base.def tdm_ai_ghostwoman.def tdm_ai_humanoid.def tdm_ai_humanoid_undead.def tdm_ai_monster_spider.def tdm_ai_steambot_base.def tdm_ai_vocal_set_monster.def tdm_ai_vocal_set_revenant01.def |

Another round: snd_notice_generic needed to be added for all 5 horse types; I had only added it to the first type. The code line that emitted snd_notice_generic hadn’t made it into the committed version. rev 5415: HitByMoveableState.cpp State.cpp rev 12795: tdm_ai_animal_horse2.def |

Another round: Change mass threshold beneath which a falling object that would have KO’ed an AI kills them instead. Changed from 5 to 50 to kill a normal-sized spider. rev 5420: Actor.h |

Another round: Only set the 1s timer for when damage can next be applied if damage was taken. rev 5458: AI.cpp Moveable.cpp |
