Struct MapRenderer

pub struct MapRenderer {
    pub buffer: InstanceBuffer<MapVertex>,
}

Instance Buffer Setup for Map’s.

Fields

buffer: InstanceBuffer<MapVertex>

Instance Buffer holding all Rendering information for Map’s.

Implementations

impl MapRenderer

pub fn new( renderer: &mut GpuRenderer, map_count: u32, ) -> Result<Self, GraphicsError>

Creates a new MapRenderer.

Arguments

• map_count: The number of Maps to presize the instance buffer by.

pub fn add_buffer_store( &mut self, renderer: &GpuRenderer, index: OrderedIndex, buffer_layer: usize, )

Adds a Buffer OrderedIndex to the Rendering Store to get processed. This must be done before MapRenderer::finalize but after Map::update in order for it to Render.

Arguments

• index: The OrderedIndex of the Object we want to render.
• buffer_layer: The Buffer Layer we want to add this Object too.

pub fn finalize(&mut self, renderer: &mut GpuRenderer)

Finalizes the Buffer by processing staged OrderedIndex’s and uploading it to the GPU. Must be called after all the MapRenderer::add_buffer_store’s.

pub fn map_update( &mut self, map: &mut Map, renderer: &mut GpuRenderer, atlas: &mut AtlasSet, buffer_layers: [usize; 2], )

Updates a Map and adds its OrderedIndex’s to staging using MapRenderer::add_buffer_store. This must be done before MapRenderer::finalize in order for it to Render.

Arguments

• map: Map we want to update and prepare for rendering.
• atlas: AtlasSet the Map needs to render with.
• buffer_layers: The Buffer Layer’s we want to add this Object too.

pub fn use_clipping(&mut self)

Map does not use Clipping.
