/// minimal example of adding a custom render pipeline in bevy 0.11.
///
/// When this example runs, you should only see a blue screen. There are no
/// vertex buffers, or anything else in this example.  Effectively it is
/// shader-toy written in bevy.
///
/// This revision adds a post-processing node to the RenderGraph to
/// execute the shader.  Thanks to @Jasmine on the bevy discord for
/// suggesting I take a second look at the bevy post-processing example

//! Example workaround for ecs-based race-conditions when used in muds.
//! The key problem is two characters stunning each other in the same
//! frame, only one of them should end up stunned.
//!
//! This solution in bevy uses an exclusive system that runs without
//! world deferment.

Navigate cscope in neovim using telescope with multiple databases

Setup:
  local cscope = require('cscope')
  -- look for cscope.out in the current working directory
  cscope.add_database { path = "." }
  -- add a second database and set the top-level path for files in that db
  cscope.add_database {
    path = "/project/altitude/src",

// This is a rough & dirty fork of `bevy_picking_raycast` that supports multiple raycast sets.
// This is needed when you have multiple cameras you want to raycast from at the same time.
// The key change is making the `Backend` generic for raycast sets.  It's harder to work
// with as it requires an understanding of `bevy_mod_raycast`.
//
// Other changes: removed `Picking` component management; added enable/disable via config

//! A raycasting backend for `bevy_mod_picking` that uses `bevy_mod_raycast` for raycasting.
