Detailed Description

A framework-integrated convex polygon shape.

Convex wraps sf::ConvexShape inside Graphic<>, giving it the full framework trait set: Subscribable (click, hover, update), Flaggable, Positionable, and Draggable.

After construction, set the point count and define each vertex using the inherited sf::ConvexShape API. The shape must be convex — all interior angles less than 180° — for SFML to render it correctly.

Usage

ml::Convex hex;
hex.setPointCount(6);
hex.setPoint(0, {60.f,   0.f});
hex.setPoint(1, {120.f, 30.f});
hex.setPoint(2, {120.f, 90.f});
hex.setPoint(3, {60.f, 120.f});
hex.setPoint(4, {0.f,   90.f});
hex.setPoint(5, {0.f,   30.f});
hex.setFillColor(sf::Color(80, 160, 80));
hex.setPosition({200.f, 200.f});
hex.onClick([]{ std::cout << "hex clicked\n"; });
addComponent(hex);

With a manifest

ConvexWith<Manifest> layers a manifest's flags and states onto the shape:

class MyHex : public ml::ConvexWith<MyManifest> {};

ml::ConvexWith

Convex with an attached manifest.

bounds The world-space rectangle within which the component may be dragged.

◆ setDragBounds() [2/2]

void ml::Draggable::setDragBounds ( const sf::FloatRect & bounds )

inherited

Constrain drag movement to an axis-aligned bounding rectangle.

While bounds are set, the component's position is clamped so that its top-left corner never moves outside bounds during a drag gesture. Bounds are applied in world coordinates.

Call clearDragBounds() to remove the constraint and allow free movement again.

Parameters

bounds The world-space rectangle within which the component may be dragged.

◆ setFlag() [1/2]

void ml::FlagManager< Flag >::setFlag	(	State	state,
		bool	status )

inherited

Set a flag to an explicit value.

Parameters

state	The flag to modify.
status	`true` to enable, `false` to disable.

◆ setFlag() [2/2]

void ml::FlagManager< Flag >::setFlag	(	State	state,
		bool	status )

inherited

Parameters

state	The flag to modify.
status	`true` to enable, `false` to disable.

◆ setFramerate() [1/2]

void ml::Positionable::setFramerate ( float framerate )

inherited

Set the assumed framerate for movement interpolation.

moveTo generates a queue of intermediate positions based on this value. Defaults to 60 fps. Call this if your application runs at a different target rate to keep animation timing accurate.

Parameters

framerate Target framerate in frames per second.

void ml::Positionable::setFramerate ( float framerate )

inherited

Set the assumed framerate for movement interpolation.

moveTo generates a queue of intermediate positions based on this value. Defaults to 60 fps. Call this if your application runs at a different target rate to keep animation timing accurate.

◆ setState() [1/2]

std::enable_if_t<!std::is_void_v< T > > ml::StateManager< extract_State< DraggableManifest >::type >::setState ( T newState )

inherited

Transition to a new state.

Fires the exit callback with the current state, updates the stored state to newState, then fires the enter callback with the new state. Either callback may be unset (nullptr), in which case it is skipped.

Parameters

newState The state to transition into.

◆ setState() [2/2]

std::enable_if_t<!std::is_void_v< T > > ml::StateManager< extract_State< DraggableManifest >::type >::setState ( T newState )

inherited

Transition to a new state.

Fires the exit callback with the current state, updates the stored state to newState, then fires the enter callback with the new state. Either callback may be unset (nullptr), in which case it is skipped.

Parameters

newState The state to transition into.

◆ subscribe() [1/4]

void ml::Subscribable::subscribe	(	ENUM_TYPE	event,
		Callback	callback )

inherited

Subscribe to an enum-keyed event with a no-argument callback.

Convenience overload for callbacks that do not need access to the raw SFML event.

Template Parameters

ENUM_TYPE Any enum type.

Parameters

event	The enum value identifying the event to subscribe to.
callback	Function invoked with no arguments when the event fires.

◆ subscribe() [2/4]

void ml::Subscribable::subscribe	(	ENUM_TYPE	event,
		EventCallback	callback )

inherited

Subscribe to an enum-keyed event with a full SFML event callback.

The callback is invoked each time the event fires and the framework's filter (defined by the associated EventDispatcher) passes this component. The std::optional<sf::Event> parameter carries the raw SFML event when one is available, or std::nullopt for frame events.

Template Parameters

ENUM_TYPE Any enum type — ml::Event for built-in events, or a manifest event enum for custom events.

Parameters

event	The enum value identifying the event to subscribe to.
callback	Function invoked with the SFML event when the event fires.

◆ subscribe() [3/4]

template<typename ENUM_TYPE>

void ml::Subscribable::subscribe	(	ENUM_TYPE	event,
		Callback	callback )

inherited

Subscribe to an enum-keyed event with a no-argument callback.

Convenience overload for callbacks that do not need access to the raw SFML event.

Template Parameters

ENUM_TYPE Any enum type.

Parameters

event	The enum value identifying the event to subscribe to.
callback	Function invoked with no arguments when the event fires.

◆ subscribe() [4/4]

template<typename ENUM_TYPE>

void ml::Subscribable::subscribe	(	ENUM_TYPE	event,
		EventCallback	callback )

inherited

Subscribe to an enum-keyed event with a full SFML event callback.

The callback is invoked each time the event fires and the framework's filter (defined by the associated EventDispatcher) passes this component. The std::optional<sf::Event> parameter carries the raw SFML event when one is available, or std::nullopt for frame events.

Template Parameters

ENUM_TYPE Any enum type — ml::Event for built-in events, or a manifest event enum for custom events.

Parameters

event	The enum value identifying the event to subscribe to.
callback	Function invoked with the SFML event when the event fires.

◆ toggleFlag() [1/2]

void ml::FlagManager< Flag >::toggleFlag ( State state )

inherited

state The flag to toggle.

◆ toggleFlag() [2/2]

void ml::FlagManager< Flag >::toggleFlag ( State state )

inherited

Flip a flag between true and false.
