In Sonic games, moving and reacting to the environnement and badnics is a big part of how the game works. A lot of ennemies are diffentiated in how you'll beat them and avoid their attack.

Some notions that would be useful

Map attacks to button instead of being in a list
Let the player chain attacks, maybe with some mechanics like either timing or actions points.
Adding notion of placing ourself and moving could be nice ?

I don't think we should think with with Beat Them up combos, but with more "actions chains", like in an Unleashed.

I see two main possibility:

Turn based (but make avoiding attack harder to conceptualize) where the characters and ennemies have their turn, but in a more dynamic fashion
"Semi-turn-based", where the characters act each after the others and can move/avoid stuff/attack and the ennemies moves and attack "dynamically" more like common Sonic ennemies, with a sort of "relay" after each one is finished. Absent character would regain slowly their action points.

( The second add some possibilities, like some character being more "support" that "prepare the terrain" like Tails that could build some stuff ).

The ennemies would be divided into

basic ennemies (simple patterns of actions, do stuff like "go to the ennemies and try to dash on him", are basically coded with a parent that have behavior and stuff)
boss (have some patterns of attacks, like big powerfull ennemies)
rivals (have some AI that try to use the different actions of a character)

Dev plan
0 : Preparatory phase

Add more buttons to map all future actions ✅
Add (optionnal) character switching to the subgame scene ✅
Connect player object to characters ✅
Basic CBS-like maps ✅
Add Finite State Machine ✅

1 : Basic systems

Add a parent "ennemy" item that can just move to the player if they notice and have some "chill behavior" if they don't + add initial support for aerial ennemies
- Implement a Motobug and a Spinner, that can't attack yet.
Add support for damage to the player and a spike ball
- Add support for being KO
Add back the punching combo
Add a win condition system and two condition (all ennemies, goal panel)
- Add the victory screen
Add a game over screen

2 : Complete with more stuff

Add basic ennemies with corresponding actions/attacks
--- Motobug :: Go to us, attack by dashing.
--- BuzzBomber :: Go to us, shot when near enough ?
--- Crabmeat :: Go to us, shoot bullet from both sides
--- Coconut :: On a tree (which is a separate object), and shoot boombs when we go near them
Add some more attacks
- Add a special attack/action for Sonic, Tails and Amy
Add defending

3 : Add variations

Rival support
- Add support for "cloning" a character to a rival
- Create a "rival" object ennemy
- Add to attacks a "when to use them" API for rivals
Add support for different maps
- Make ennemies able to navigate Battle's maps
Add items, might have to change compared to the present items.
- Add a special hud for that, to select a good item
- Add a "use item" button to use the item (wow)
- Add a more complexe "pause UI" to use items on other characters
Add a Boss
- TODO

Possible schemes

V1 - Usage of item in real-time

A: Jump
B: Basic hit (doesn't use action point) + Interact
X, Y: Special actions
Left stick: move
Right stick: camera ?
R, L : Switch characters
R1: Use item
R2: Lock target
up, down: Switch wisp mode & item mode
left, right: Switch items

Issues:

Would be nice to have a "defend" action
Two special attack add more combo and make the game a bit too much beat them all

V2 - Item Menu

A: Jump
B: Basic hit (doesn't use action point) + Interact
X: Show item menu
Y: Dash
Left stick: move
Right stick: camera ?
R, L : Switch characters
R1: Defend
R2: Lock target
up, down, left, right: Special actions

To handle behavior intelligently, we'll need a to add support for a finite state machine subsystem into birb's actor system, as both fighter and IA will need to have their own states.

State should have callback for when they start, end or begin.

Something like

StateMachine:extend()
StateMachine.addState("punch", punchState)

StateMachine.states = {}

function StateMachine.addState(name, state, isDefault)
	StateMachine.states.list[name] = StateMachine
    
    if (isDefault == true) then
    	StateMachine.states.default = name
	end
end

function StateMachine:initStates()
	self.currentState = StateMachine.states.default
end

function StateMachine:setState(state)
	StateMachine.states.list[state].start(self, )
end

function StateMachine:getState()
	return self.currentState
end

Something like ```lua StateMachine:extend() StateMachine.addState("punch", punchState) StateMachine.states = {} function StateMachine.addState(name, state, isDefault) StateMachine.states.list[name] = StateMachine if (isDefault == true) then StateMachine.states.default = name end end function StateMachine:initStates() self.currentState = StateMachine.states.default end function StateMachine:setState(state) StateMachine.states.list[state].start(self, ) end function StateMachine:getState() return self.currentState end ```
