Struct bevy_render::render_phase::RenderCommandState
source · pub struct RenderCommandState<P: PhaseItem + 'static, C: RenderCommand<P>> { /* private fields */ }
Expand description
Wraps a RenderCommand
into a state so that it can be used as a Draw
function.
The RenderCommand::Param
, RenderCommand::ViewWorldQuery
and
RenderCommand::ItemWorldQuery
are fetched from the ECS and passed to the command.
Implementations§
source§impl<P: PhaseItem, C: RenderCommand<P>> RenderCommandState<P, C>
impl<P: PhaseItem, C: RenderCommand<P>> RenderCommandState<P, C>
sourcepub fn new(world: &mut World) -> Self
pub fn new(world: &mut World) -> Self
Creates a new RenderCommandState
for the RenderCommand
.
Trait Implementations§
source§impl<P: PhaseItem, C: RenderCommand<P> + Send + Sync + 'static> Draw<P> for RenderCommandState<P, C>where
C::Param: ReadOnlySystemParam,
impl<P: PhaseItem, C: RenderCommand<P> + Send + Sync + 'static> Draw<P> for RenderCommandState<P, C>where C::Param: ReadOnlySystemParam,
source§fn prepare(&mut self, world: &World)
fn prepare(&mut self, world: &World)
Prepares the render command to be used. This is called once and only once before the phase
begins. There may be zero or more draw
calls following a call to this function.
source§fn draw<'w>(
&mut self,
world: &'w World,
pass: &mut TrackedRenderPass<'w>,
view: Entity,
item: &P
)
fn draw<'w>( &mut self, world: &'w World, pass: &mut TrackedRenderPass<'w>, view: Entity, item: &P )
Fetches the ECS parameters for the wrapped RenderCommand
and then renders it.
