// eAthena TODO for Monster AI
|
|
// -----------------------------------------
|
|
// The idea of this file is to write a system to use for mob AI because
|
|
// to put it bluntly, our mobs are stupid. If we can pull off some sweet
|
|
// AI, we will own the other emulators.
|
|
//
|
|
// What we have here are 2 columns. I describe them below...
|
|
// - 'mode' : Mode is when the monster can attack, like, can it move? can it
|
|
// attack first? can it assist other monsters?
|
|
//
|
|
// - 'AI' : AI is the smart part of the monster. This is how the monster
|
|
// will actully go about attacking something. For example we
|
|
// could make archer skeletons fire an arrow or 2, then flee
|
|
// and fire a few more arrows. Or we could have them avoid other
|
|
// classes with range (archers, mages). We could also have mobs
|
|
// run when being sniped off cliffs by archers/mages (wont they
|
|
// hate that, but in reality, thats what they would do).
|
|
//
|
|
// The mode flags will be given an ID to the power of 2, (binary style, like
|
|
// job id's in the item_db) and added together to make the mode. But before
|
|
// the system can be written we need a nice file to explain it. That would be
|
|
// this file. So add away, when it looks done, begin the implementation.
|
|
//
|
|
// Also, if possible, new config file in /conf/. 'mob_ai_athena.conf'. This is
|
|
// where mob AI is enabled/disable. And options can be set to allow and dis-
|
|
// allow certin modes. Ex: People like the AI, but dont like one options, can
|
|
// simply disable THAT AI feature rather then rewriting mob_db to remove it.
|
|
//
|
|
// I wrote the first modes, C devs, move them around as you see fit for programming.

'mode'
|
|
Immobile - Monster can not move, can not be moved (like by archers knockback skills)
|
|
Agressive - Monster can attack first (doesn't mean it will, decided in 'AI')
|
|
Detect cast - Monster will detect if someone is casting on it, and attack back
|
|
Assist - Monster will help other monsters (what monsters it will assist is decided in 'AI')
|
|
Looter - Monster will loot items (if 'Agressive' flag is set, it will attack before looting)
|
|
No Target Change - Monster will not start attacking another target until the first target is dead or out of range
|
|
Passive - Monster will not attack back (ever, unless 'Agressive' flag is also set?)
|
|
Detects Hidden - Monster can see hidden players
|
|
|
|
'ai'
|
|
NoAI - Doesn't do anything (plants)
|
|
NoSnipe - Monster will run away if being 'sniped' from a clif by archer, mage, etc.
|
|
AttackFlee - Monster will attack, then flee, attack, then flee, etc (Archer Skels, run away, shoot arrow, etc)
|
|
AttackRange1 - Will only attack if player is in a set range [0-3] (It's like the player is close, its a threat now)
|
|
AttackRange2 - Will only attack if player is in a set range [4-6]
|
|
ClassFlee1 - Will run from any player with range (archers, mages, thiefs with bows)
|
|
NoviceNoFlee - Will not run if a player is a novice
|
|
LevelFlee - Wlll run if player is of a higher level (porings would run from level 99s, AHH DONT KILL ME!)
|
|
AvoidPlayer - Will run if it sees any player (So it cancels 'Agressive' flag)
|
|
AttackMostDamage - Will attack the player doing the overall most damage
|
|
AttackLessDamage - Will attack the player doing the overall least damage
|
|
AttackLowestLevel - Will attack the lowest level first
|
|
AttackHighestLevel - Will attack the highest level first
|
|
WarpLowHP - Will warp if HP is low (how low is low?)
|
|
NeverStop - Monster will always be on the move, never stop walking. (Is over-ridden by 'Immobile' flag)
|
|
|
|
|
|
//
|
|
// Again, more stuff...
|
|
//
|
|
// The monster spawns sripts need some more params. some examples...
|
|
//
|
|
// We have: map,x,y,offsetx,offsety, ...
|
|
// What if we added more? To only let the monster move so far off from
|
|
// where it was spawned. It could 'guard' an arena, an exit/enterance
|
|
// an npc, whatever =).
|
|
//
|
|
// .... ID,time,time,blah...,mode,WAP
|
|
// Have monsters walk a certin path. Waypoint files are your friend.
|
|
// If a monster has a WAP (optional) it will walk this path.
|
|
// Guardians on patrol? Could be interesting.
|
|
//
|
|
// Add more if you think of any =)
|
|
//
|
|
// If you don't like an idea, comment why, dont remove it.
|
|
// example: (using this one cuz not sure about it)
|
|
//
|
|
// // NeverStop - Will/Could cause lag, don't think its a good idea -name
|
|
// NeverStop - ...
|
|
//

Lupus: (guys, rearrange my ideas or move them as u want)
|
|
Some memory - speed optimizations:
|
|
|
|
There'a big "for cycle" when u look up for a place to mob spawn.
|
|
It could be made quite fast:
|
|
On server .GAT loading you should make an array with OFFSETS (not even X,Y) of right
|
|
places for future mob spawns.
|
|
If the waypoints aren't found for the loadied map then you should make at least 1-2 waypoints automatically.
|
|
|
|
About AI:
|
|
EACH map has defined mobs. Your mob should have a flag "healer", "supporter" etc. "weak", "ranged attacker"
|
|
and each map should contain an attached list of mobs with their types
|
|
when one MVP is hurt it'd look for "helpers", "healers".
|
|
And if a mob is almost 0 HP it should look for helpers or look for other mobs ranged attackers
|
|
defence. Etc.
|
|
|
|
Mobs AI should be WRITTEN IN SPECIAL SCRIPTS.
|
|
Some default mobs will use the same script.
|
|
And some advanced ones will use their own.
|
|
|
|
MOB-scripts are quite interesting. (remember Robot-Wars game?)
|
|
|
|
Gulid Wars:
|
|
I think guardians should be able to warp from room to room using WARPS like common Players.
|
|
|
|
|
|
Aria's Ideas: (do whatever u want)
|
|
|
|
We can make aggressive monsters make ambushes, where one attacks and runs away to a huge group of the same monster
|
|
|
|
instead of dropping 2 x1 items, just drop 1 x2 item
|
|
|
|
make AI vary inside of a group of monsters (IE 1/2 porings do 1 thing, and the other half do another)
|
|
|
|
aggressive monsters sould surround enemies, not just blindly attack them
|
|
|
|
we should also make monsters look as player-like as possible. There should be groups traveling together, or 2 monsters
|
|
next to eachother, chatting.
|
|
|
|
we shouldn't let mobs spawn right infront of people, like in anime or manga. they always walk towards you, or you walk
|
|
towards them.
|
|
|
|
let mob stats vary a little bit - every mob shouldn't be the exact same. if it's stronger it gives more exp, and vice
|
|
versa.
|
|
|
|
have a monster be able to use its drops, and not drop it. like a poring using an apple. |
