Enemy AI

Enemy AI To think about:

Impaired
Enemies that are "Blind" (They respond to movement but not to your presence) i.e. Old Hero, Gears of War thingy, (a la Predator where Arnold is covered in mud) or playing a game of Red light/Green light)

Enhanced (change the rules)
Enemies that can move through geometry (i.e. spirits through walls) of can use water (serpents ultima) or fire (balrog Ultima)

Immunity
Enemies that are immune to normal weapons (i.e. they have to be killed by "special weapons" or the environment (Ultima 5 shadowlords glass sword) Oblivion ghosts.

Territorial
Enemies that don't care about you unless you enter thier territory guards,. etc.

Hit & Run (Thieves)
Enemies that Steal/Poison/Curse and run away (their goal isnt to hurt you but rather steal/poison/curse you) i.e. they blind you/steal gold or items (a la Golden Axe)

To Death
Enemies that fight you to the death (pretty much most enemies in AI nowadays)

Summoners
Enemies that call in reinforcements (God of War 2, Xivalvi Oblivion )

Suicidal/Kamakazi
Enemies who rho run straight at you and explode to cause damage (Serious Sam Bombers)

Retreat/Avoid
Run from you at all costs (Leprechauns) dont attempt to do damage (Deer in Oblivion, Crystal Geckos)

Passive
Don't fire unless fired upon (Bison FalloutNV)

Ranged
Keep thier distance and used ranged attacks only (archers)

Splitters
Enemies that when attacked and not killed split into 2 (slimes in Ultima)

Triggered (basically territorial)
Gargoyles
Mimics (Fake Treasure Chests)
Guards after you steal something in Ultima

Organized/Group

Enemies that attack in groups (those things in Dead Space)

Environmental

Enemies that change the environment (i.e. light ground on fire, etc. that causes damage)

good examples of these might be fire elementals who can light the ground on fire where they move...

so if they are retreating you have to run through the wake/trail of fire to do backstabs. also they may retreat go back into fire to regain health.

Dragons that can shoot out arcs of fire lighting the ground on fire

Responsive

Evaluates what you are doing to counter it

Hybrid
Aggressive/Retreat : Might get up close and do melee until health is low and change to Retreat/Avoid

--- how about some enemies, (when they are hurt) might retreat to homebase (and this is how you can find your way to treasure)... gremlins and leprechans (i.e. find the nest)

--bystanders who dont interfere unless disturbed
