Detailed Description

Manages a stack of layers with separate overlay layers.

The LayerStack provides ordered management of layers and overlays:

• Regular layers are rendered in the middle of the stack
• Overlay layers are always rendered on top
• Supports dynamic adding/removing of layers
• Maintains proper render and update order

Note

Layers are processed from bottom to top for updates, and top to bottom for events

Member Function Documentation

begin()

std::vector< Layer * >::iterator AE::Core::LayerStack::begin ( )

inline

Gets iterator to the beginning of the layer stack.

Returns

Iterator pointing to first layer

end()

std::vector< Layer * >::iterator AE::Core::LayerStack::end ( )

inline

Gets iterator to the end of the layer stack.

Returns

Iterator pointing past the last layer

PopLayer()

void AE::Core::LayerStack::PopLayer

(

const Layer *

layer

)

Removes a regular layer from the stack.

Parameters

layer

Pointer to the layer to remove

PopOverlay()

void AE::Core::LayerStack::PopOverlay

(

const Layer *

overlay

)

Removes an overlay layer from the stack.

Parameters

overlay

Pointer to the overlay layer to remove

PushLayer()

void AE::Core::LayerStack::PushLayer

(

Layer *

layer

)

Adds a regular layer to the stack.

Parameters

layer

Pointer to the layer to add

Regular layers are inserted before overlay layers to maintain proper rendering order

PushOverlay()

void AE::Core::LayerStack::PushOverlay

(

Layer *

overlay

)

Adds an overlay layer to the stack.

Parameters

overlay

Pointer to the overlay layer to add

Overlay layers are always added to the end of the stack to render on top
