Public Types
typedef fl::FixedMap< int, FxPtr, FASTLED_FX_ENGINE_MAX_FX >	IntFxMap

Public Member Functions
	FxEngine (uint16_t numLeds, bool interpolate=true)
	Constructs an FxEngine with the specified number of LEDs.

	~FxEngine ()
	Destructor for FxEngine.

IntFxMap &	_getEffects ()

int	addFx (Fx &effect)
	Adds a new effect to the engine.

int	addFx (FxPtr effect)
	Adds a new effect to the engine.

bool	draw (fl::u32 now, CRGB *outputBuffer)
	Renders the current effect or transition to the output buffer.

int	getCurrentFxId () const

FxPtr	getFx (int index)
	Retrieves an effect from the engine without removing it.

bool	nextFx (uint16_t transition_ms=500)
	Transitions to the next effect in the sequence.

FxPtr	removeFx (int index)
	Requests removal of an effect from the engine, which might not happen immediately (for example the Fx needs to finish a transition).

bool	setNextFx (int index, uint16_t duration)
	Sets the next effect to transition to.

void	setSpeed (float scale)
	Sets the speed of the fx engine, which will impact the speed of all effects.

Private Attributes
FxCompositor	mCompositor
	Handles effect transitions and rendering.

int	mCounter = 0

int	mCurrId
	Id of the current effect.

uint16_t	mDuration = 0
	Duration of the current transition.

bool	mDurationSet
	Flag indicating if a new transition has been set.

IntFxMap	mEffects
	Collection of effects.

bool	mInterpolate = true

TimeWarp	mTimeFunction
