@:value(true)destroySubStates:Bool = true
If substates get destroyed when they are closed, setting this to
false might reduce state creation time, at greater memory cost.
@:value(true)persistentDraw:Bool = true
Determines whether or not this state is updated even when it is not the active state.
For example, if you have your game state first, and then you push a menu state on top of it,
if this is set to true, the game state would continue to be drawn behind the pause state.
By default this is true, so background states will continue to be drawn behind the current state.
If background states are not visible when you have a different state on top,
you should set this to false for improved performance.
@:value(false)persistentUpdate:Bool = false
Determines whether or not this state is updated even when it is not the active state.
For example, if you have your game state first, and then you push a menu state on top of it,
if this is set to true, the game state would continue to update in the background.
By default this is false, so background states will be "paused" when they are not active.
read onlysubStateClosed:FlxTypedSignal<FlxSubState ‑> Void>
A FlxSignal that dispatches when a sub state is closed from this state.
4.9.0
.read onlysubStateOpened:FlxTypedSignal<FlxSubState ‑> Void>
A FlxSignal that dispatches when a sub state is opened from this state.

@:value(0)read onlylength:Int = 0
The number of entries in the members array. For performance and safety you should check this
variable instead of members.length unless you really know what you're doing!
maxSize:Int
The maximum capacity of this group. Default is 0, meaning no max capacity, and the group can just grow.
read onlymemberAdded:FlxTypedSignal<T ‑> Void>
A FlxSignal that dispatches when a child is added to this group.
4.4.0
.read onlymemberRemoved:FlxTypedSignal<T ‑> Void>
A FlxSignal that dispatches when a child is removed from this group.

@:value(idEnumerator++)ID:Int = idEnumerator++
A unique ID starting from 0 and increasing by 1 for each subsequent FlxBasic that is created.
@:value(true)alive:Bool = true
Useful state for many game objects - "dead" (!alive) vs alive. kill() and
revive() both flip this switch (along with exists, but you can override that).
cameras:Array<FlxCamera>
This determines on which FlxCameras this object will be drawn. If it is null / has not been
set, it uses the list of default draw targets, which is controlled via FlxG.camera.setDefaultDrawTarget
as well as the DefaultDrawTarget argument of FlxG.camera.add.
read onlycontainer:Null<FlxContainer>
The parent containing this basic, typically if you check this recursively you should reach the state

onFocus():Void
This method is called after the game receives focus. Can be useful for third party libraries, such as tweening engines.
onFocusLost():Void
This method is called after the game loses focus. Can be useful for third party libraries, such as tweening engines.
startOutro(onOutroComplete:() ‑> Void):Void
Called from FlxG.switchState(), when onOutroComplete is called, the actual state
switching will happen.
Note: Calling super.startOutro(onOutroComplete) will call onOutroComplete.

add(basic:T):T

.@:value({ revive : true, force : false })recycle(?objectClass:Class<T>, ?objectFactory:() ‑> T, force:Bool = false, revive:Bool = true):T
Recycling is designed to help you reuse game objects without always re-allocating or "newing" them.
It behaves differently depending on whether maxSize equals 0 or is bigger than 0.
maxSize > 0 / "rotating-recycling" (used by FlxEmitter):
- at capacity: returns the next object in line, no matter its properties like alive, exists etc.
- otherwise: returns a new object.
maxSize == 0 / "grow-style-recycling"
- tries to find the first object with exists == false
- otherwise: adds a new object to the members array
WARNING: If this function needs to create a new object, and no object class was provided,
it will return null instead of a valid object!
Parameters:
objectClass | The class type you want to recycle (e.g. |
|---|---|
objectFactory | Optional factory function to create a new object
if there aren't any dead members to recycle.
If |
force | Force the object to be an |
revive | Whether recycled members should automatically be revived
(by calling |
Returns:
A reference to the object that was created.
@:value({ splice : false })remove(basic:T, splice:Bool = false):T
Removes an object from the group.
Parameters:

|---|---|
splice | Whether the object should be cut from the array entirely or not. |
Returns:
The removed object.
replace(oldObject:T, newObject:T):T
Replaces an existing FlxBasic with a new one.
Does not do anything and returns null if the old object is not part of the group.
Parameters:
oldObject | The object you want to replace. |
|---|---|
newObject | The new object you want to use instead. |
Returns:
The new object.
reviveMembers():Void
Calls revive() on the group's killed members and then on the group itself.

.@:value({ order : FlxSort.ASCENDING })inlinesort(func:(Int, T, T) ‑> Int, order:Int = FlxSort.ASCENDING):Void
Call this function to sort the group according to a particular value and order.
For example, to sort game objects for Zelda-style overlaps you might call
group.sort(FlxSort.byY, FlxSort.ASCENDING) at the bottom of your FlxState#update() override.
Parameters:
func | The sorting function to use - you can use one of the premade ones in
|
|---|---|
order | A constant that defines the sort order.
Possible values are |

getCameras():Array<FlxCamera>
The cameras that will draw this. Use this.cameras to set specific cameras for this object,
otherwise the container's cameras are used, or the container's container and so on. If there
is no container, say, if this is inside FlxGroups rather than a FlxContainer then the
default draw cameras are returned.
