add Controller object

[loteque]

• Add controller object
• gun component uses controller object

• This technically closes #168
• ...but I think more work should be done for it to be useful if we want couch coop. We could close this now but I wouldn't recommend using it until we handle multiple player inputs, which will be done here and in a PlayerManager.
  • If we use this now and add multiplayer later we will have to change code in every file we use this in.
• We are using two different methods of handling input currently, how we handle input in player controller is different from how we've had to handle input in gun controller and I think we should bring these into alignment, especially if we want to do coop.

Quick sketch of what a player manager would look like: PlayerManager.gd

extends Node2D
devices = [dev_guid]
players = {player_id : dev_id}
    set:
    get:

func _get_new_player_id() -> int:

func _get_new_device_id() -> int:

func _get_dev_guid() -> int:

func _add_player(player_id: int, dev_id: int, dev_guid: String):
    var player = load(PlayerController.gd).new(player_id, dev_id, dev_guid)
    $parent.add_child(player).name(dev_guid)

func _remove_player(dev_id: int):
    get_player_by_dev_id(dev_id).queue_free

_on_joypad_connect(player):
    _add_player(_get_new_player_id(), _get_new_dev_id(), _get_dev_guid())

_on_joypad_disconnect(dev_id):
    _remove_player(dev_id)
