flixel-abstractinput
Small library for HaxeFlixel provides another abstraction layer which allows user to group different input, such as keyboard, mouse and gamepad (axis and buttons) in several abstract actions, and then check them. Actions use Int numbers as ids or names. For every action you can bind standart input source, for axample keys of keyboard or axis of gamepad, as more as you need, but every source can be used only once.
Input source can be:
- keyboard keys (FlxKey)
- mouse keys (MouseID)
- gamepad keys (FlxGamepadInputID)
- gamepad axis (GamepadAxisID)
Actions
Action has standart updateble vars
- justPressed:Bool
- justReleased:Bool
- pressed:Bool
and the unified
- value:Float
value can be from 0 to 1 depends on input type. For buttons it can be 0 or 1, for axis it can be 0..1.
Axis sources are devided for positive and negative directions, bacause of value of value.
Basic usage Example
var actions:AbstractInputManager = new AbstractInputManager();
var a = actions.addAction(GO_UP);
a.addKey(FlxKey.W);
a.addKey(FlxKey.UP);
a.addGamepadAxis(GamepadAxisID.LEFT_STICK_Y_MINUS);
a=actions.addAction(GO_DOWN);
a.addKey(FlxKey.S);
a.addKey(FlxKey.DOWN);
a.addGamepadAxis(GamepadAxisID.LEFT_STICK_Y_PLUS);
a=actions.addAction(GO_LEFT);
a.addKey(FlxKey.A);
a.addKey(FlxKey.LEFT);
a.addGamepadAxis(GamepadAxisID.LEFT_STICK_X_MINUS);
a=actions.addAction(GO_RIGHT);
a.addKey(FlxKey.D);
a.addKey(FlxKey.RIGHT);
a.addGamepadAxis(GamepadAxisID.LEFT_STICK_X_PLUS);
a=actions.addAction(ATTACK);
a.addMouseKey(MouseID.MOUSE_LEFT);
a.addMouseKey(FlxGamepadInputID.A);
///in update
actions.update();
if (actions.anyChanged([GO_UP, GO_DOWN, GO_LEFT, GO_RIGHT])){//check if any of GO_UP, GO_DOWN, GO_LEFT, GO_RIGHT was changed
if (actions.value(GO_RIGHT) == 1){
//key GO_RIGHT is pressed
}
if (actions.value(GO_LEFT) == 0){
//key GO_LEFT is not pressed
}
//if we need to do smth on change in any of this actions
}Custom Action ids
You can create your custom enum class for action ids or use Int numbers directly
Code of standart AbstractActionID enum class:
@:enum
abstract AbstractActionID(Int) from Int to Int{
public static var fromStringMap(default, null):Map<String, AbstractActionID>
= FlxMacroUtil.buildMap("AbstractInputManager.AbstractActionID");
public static var toStringMap(default, null):Map<AbstractActionID, String>
= FlxMacroUtil.buildMap("AbstractInputManager.AbstractActionID", true);
var NONE = -1;
var GO_UP = 1;
var GO_DOWN = 2;
var GO_LEFT = 3;
var GO_RIGHT = 4;
var ATTACK = 5;
var GRENAGE = 6;
var FLASHLIGHT = 7;
var JUMP = 8;
var NEXT_W = 9;
var PREV_W = 10;
var SLOT_1 = 11;
var SLOT_2 = 12;
var SLOT_3 = 13;
var SLOT_4 = 14;
var SLOT_5 = 15;
var SLOT_6 = 16;
var SLOT_7 = 17;
var SLOT_8 = 18;
var SLOT_9 = 19;
var USE = 20;
var USE_ITEM = 21;
var NEXT_ITEM = 22;
var PREV_ITEM = 23;
@:from
public static inline function fromString(s:String)
{
s = s.toUpperCase();
return fromStringMap.exists(s) ? fromStringMap.get(s) : NONE;
}
@:to
public inline function toString():String
{
return toStringMap.get(this);
}
