Expand description

This trait should be used instead of the Node trait when making a render node that runs on a view.

It is intended to be used with ViewNodeRunner

Required Associated Types§

type ViewQuery: ReadOnlyQueryData

The query that will be used on the view entity. It is guaranteed to run on the view entity, so there’s no need for a filter

Required Methods§

fn run<'w>( &self, graph: &mut RenderGraphContext<'_>, render_context: &mut RenderContext<'w>, view_query: <Self::ViewQuery as WorldQuery>::Item<'w>, world: &'w World, ) -> Result<(), NodeRunError>

Runs the graph node logic, issues draw calls, updates the output slots and optionally queues up subgraphs for execution. The graph data, input and output values are passed via the RenderGraphContext.

Provided Methods§

fn update(&mut self, _world: &mut World)

Updates internal node state using the current render World prior to the run method.
